The Ocotillo family is small, with just 11 species, and Fouquieria splendens is the most widely recognized. They are native to North and Central America, with a distant sister family in Madagascar. Interestingly, ocotillo is more closely related to blueberries than to cactus. The flowers are also edible and can be used to make a tisane.

In this article, we’ll cover how to propagate ocotillo successfully. Although not a cactus, it shares many of the same propagation needs and fits well here.

Choosing an Ocotillo to Propagate

Spring is the best season to propagate ocotillo. Once the risk of frost has passed, look for a healthy plant with long, vigorous canes that bloomed and leafed frequently the previous year. 

The ideal length of a cane is around 3-5ft long, and a cane can be cut as a section of a longer cane; the main plant will regrow. Cuttings should be taken from younger, more supple growth, which is typically a little thicker than a pencil, and can look more purple in color. If the cane is quite bendy or supple, it should root well.

Thinner, younger canes are easier to cut, will heal quicker, and are less woody, so have more adaptive cell tissue.

Taking a Cutting

Removing a section of ocotillo is very simple.

You will need:

• Thick gloves
• Sterilized cutting tools - a garden knife and garden loppers
• A bucket to carry the canes in

After you’ve found a good cane to cut, it’s important to evaluate how thick it is. A clean cut is essential to prevent damage to the parent plant and help the cutting to remain healthy. 

Canes that are even a little too thick or woody, but still suitable for propagation, can be crushed by loppers, so a garden knife may be more suitable for some plants. 

Plants should be cut at a shallow angle to prevent water pooling on the main plant and increase the rooting surface area of the cutting. Take care not to go too steeply, as this creates a wound that is too big and is more likely to rot. 

Before cutting, mark which side of the cane faces south, or south-west. Tying a piece of string around one of the large thorns is an easy way. Desert plants form thicker, more sun-adapted tissue on these sides, and this will help the plant root more successfully by minimizing stress. 

Once cut, place the cutting in the bucket, which makes them much easier to carry, as the thorns can be very sharp.

Preparing the Cutting

Ocotillo stems need to dry out and form a callus before being planted, just as many other desert plants do. 

Store the canes horizontally in a semi-shaded, well-ventilated location. Ocotillo calluses very quickly, and you may find it happens in as little as 2-3 days. 

Canes can then be prepared for planting by dusting the bottoms with rooting hormones or sulfur powder. As well as encouraging the plant to root, this also helps to keep the cane base dry as it roots out.

Preparing the Ground

Ocotillos prefer sandy, slightly loamy soil. As the canes will be very unstable when planted, you may find it beneficial to amend the planting area with small stones or a small amount of gravel to provide some stability and weight at the base. 

Dig a hole that is approximately 4-6 inches deep, and complete any necessary soil amendments. The hole should be approximately 4-6 inches wide as well to help with water infiltration.

Place the cane in the hole, and gently backfill, compressing the soil with your foot to create slightly compacted layers. Amend the top surface with a few larger rocks close to the cane to stabilize the cane against wind or animal disturbance. Once the cane is stable, avoid watering the soil directly for the first few weeks.

Remember to orient the cane in the correct direction. The cane will likely survive even if you don’t do this, but for more extreme weather years, this will really benefit the plant. 

Caring For Your Ocotillo

Ocotillo does not like wet roots. Ocotillo also takes up much of its water through its stems, and is very receptive to humidity, having the ability to open and contract its stems to expose more surface area for photosynthesis and water intake.

Most of the watering for your ocotillo canes should be done through a misting of the stems. A deep watering once a month before the monsoon rains come will stimulate root growth, but misting is most effective, as the cane will not have many roots, if any at all, for the first few months. 

Ocotillo can take anywhere from 3-24 months to root. They are very resilient plants, and a little fussy about environmental conditions. You can check if your ocotillo canes are still alive through the following methods. 

1. Check for visible green on the stems. You may have to look closely, but millimeter ribbons of green are often all that can be seen on dormant plants.
2. Scratch the stem and look for green beneath the stem. In very dormant cases, plants will close up. 
3. Check how flexible the stem feels. Dead stems will be very brittle and will snap. Canes that are still alive will bend, even if only a little, and won’t snap easily.

Propagating From Seeds

Seeds can be collected from your own plants or purchased from reputable sellers online. These seeds are easy to germinate, and can provide transplantable ocotillo within 2 years. 

1. Prepare a well-draining, sandy potting mix in a small to medium container. 
2. Plant the seeds at a depth of around 1 inch, and dampen the soil all the way to the bottom. 
3. Keep the soil consistently moist until the seeds germinate and sprout above the surface. 
4. Provide intense sunlight, as a lack of, or limited, sunlight will cause seedlings to become heavy with leaves and break. Later afternoon shade will help young plants. I keep my seedlings on a northeast-facing patio.
5. Ocotillo will eventually grow a deep taproot, so a container that is at least 6 inches deep is good. 
6. Water seedlings weekly to encourage healthy growth.

Once the seedling is around 2-4 inches tall and is leafing out regularly, you can transplant it to the final location. Water the plant weekly for the first couple of months, and then reduce the watering schedule, eventually leaving irrigation to natural rainfall. 

Watering once a month in the heat of the summer is helpful for the first two years. 

Wrapping Up

Ocotillo is a delightful plant. They are wonderfully unique, have beautiful flowers, an interesting growth pattern, and a structure that is elegant and dramatic. Ocotillo will flower and leaf regularly once they are well established, which could take multiple years. However, they are an incredibly low-maintenance, keystone plant that will hold a place of pride in your garden and benefit all kinds of wildlife.

Columnar cacti are relatively simple to propagate, though the method can vary. In part 3 of this series, we’ll cover the ways to increase the number of columns in your garden and care for the parent plant after you’ve taken a cutting.

Taking a Cutting

The most effective method for most columnar cacti is to take a stem cutting. A cutting between 6 and 12 inches tall is ideal, although on smaller varieties, 2-3 inches is plenty. Taller cuttings can work, but they take longer to establish and are more prone to tipping due to their weight.

Things You’ll Need:

• A healthy parent plant
• A sharp garden knife
• 80% alcohol or another sterilizing agent
• Thick gloves and long sleeves
• Rooting hormone powder (optional)
• Well‑draining potting mix

The best time to take a columnar cactus cutting is in late spring or early summer, when the plant is healthy after the winter rains, but the temperature is not yet too hot. This balances the conditions and maximizes the chance of plant survival.

Choosing and Taking a Healthy Cutting

First, select a healthy parent plant with robust color and good growth that is not wrinkled or dry. Look for a segment that is at least 6-8 inches long and has plenty of areoles (the raised nodes along the stem), as these will produce most of the roots. You can take the cutting from the main growing stem or one of the offset shoots. 

Using your clean, sterile knife, cut the cactus just below an areole at a 45-degree angle, taking care not to nick other parts of the cactus. If the column has a ‘joint’, this is an excellent place to make the cut, and we’ll explain a little more on this later. 

Adjustments For Cacti With Joints

Some columnar cacti form joints, either along their main stems (these will be slightly constricted lines with hard tissue growth) or through arms, like myrtillocactus geometrizans. If your plant has these joints, these are excellent places to cut. The plant will root more readily from these areas as the tissue is denser, and the cut site will be smaller, allowing the plant to heal more quickly. 

Follow all the steps listed here, but note that drying and rooting will likely be faster.

Callus Your Cutting

After taking your cutting, let the wound dry and callus fully before planting. Columnar cacti may take 2-4 weeks or more to fully dry because the cut surface is larger and holds more moisture.

Place the cutting in a bright, airy spot out of direct sun and protected from rain. Good airflow speeds drying and reduces the chance of fungal issues. Rotate the cutting every few days to discourage aerial roots, which often form when one side stays shaded or pressed against a surface.

A fully callused cutting will have a firm, dry, corky surface with no remaining moisture. Once it reaches this stage, it’s ready to plant.

Rooting the Cutting

Plant your cutting in a well-draining potting mix. Keep the amount of organic matter low to reduce the chance of rot; I’ve found that incorporating some rocky soil from the garden works very well. Stake your cactus with canes if needed; you want it to stay steady while it roots.

Your cutting will likely shrivel in the weeks after you plant it, but resist the temptation to water it until it roots (around 3-4 weeks). The cacti will lose some water in the rooting process, but a well-sized cutting will have plenty of reserves and will fill out again after it roots.

Looking For Roots

My favorite test for roots with columnar cacti is to gently lift the cactus and see if the pot lifts with it. Lifting it just a quarter inch off the ground is enough. You can also look for a more vibrant coloring at the tip, or if there are any offsets from the areoles; this means the plant has rooted and is beginning to grow again.

Watering and Transplanting

Once roots emerge, water lightly and allow the soil to dry completely before watering again. As it becomes more established, start soaking the soil more deeply and more infrequently. The aim is to adapt it to dry conditions. 

Once the plant has well-established roots, is a robust, healthy color, and is putting out new growth, it’s ready to be transplanted to the final location. This usually takes a few months. 

After transplanting, water thoroughly, and then water once a week for 4-6 weeks to encourage root spreading. During the first couple of years, you may need to water it once a month during the dry spells, but it should become independent quite quickly; just keep an eye on it. 

Caring for the Parent Plant

The parent plant now has an exposed wound. The 45-degree angle of the cut, or cut at the joint, will minimize damage, but there are some steps you can take to speed up recovery.

• Additional watering - a good soak every 1-2 weeks will help the plant scab over the site. 
• Shade - bird netting will provide a 10% shade increase, which can reduce sun scorch.
• A small amount of cactus and succulent fertilizer during the late spring can renew vigor in the plant.
• Watch for pests, particularly cactus borer, that may take advantage of the soft tissue.

The parent plant will likely produce multiple offsets from the cut site that will grow from the surrounding areoles. Choosing an offset to begin with means you can retain a healthy main stem, with new growth that starts closer to the ground and is easier to manage.

Wrapping Up

With a clean cut, a full callus, and a gritty soil mix, most columnar species root reliably. The process takes time, but each stage is simple, and the plants are far more resilient than they appear. Given a few months of careful attention and the right conditions, your cutting will establish itself and begin the slow climb toward maturity, soon becoming a wonderful garden addition.

Agaves are incredibly resilient plants and a staple in desert and xeriscape gardens. Their thick leaves, fibrous roots, and carbohydrate‑rich cores allow detached pups and bulbils to survive long periods with minimal water while they establish new roots.

In this article, we’ll dive into propagation techniques and methods for growing agave. Let’s dive in.

The Primary Propagation Methods

There are three main methods for agave propagation, and each comes at a different stage of an agave’s life cycle. 

Pups

This is the easiest and most accessible method, as most agave species produce pups regularly. Agave americana, for example, will produce a handful of pups every year if the conditions are right and the plant is mature enough – usually after 3-4 years. Some agaves are solitary, however, such as A. ovatifolia, which won’t produce pups until they flower.

Choosing a Good Pup

A few cues help you pick the strongest candidates:

• Leaves should be plump and unblemished, with no soft spots or signs of rot.
• The pup should have a clear, well‑formed center—tiny, tight leaves emerging from the middle.
• A size between 3–8 inches roots most reliably: large enough to have stored energy, small enough to handle easily.

Avoid pups that are yellowing, shriveled, or growing in deep shade under the parent—they often struggle to establish.

Tools you’ll need

• A small garden trowel
• A sharp, sterilized knife, pruning saw, or pruning shears
• Thick gloves (agave can be spiky!)
• A pot filled with fast‑draining sandy cactus mix

Steps:

Use the trowel to gently excavate around the pup until you can see where it connects to the mother plant, keeping as many roots intact as possible. Not all pups will have roots, and that’s okay.

Removing the Pup

If the pup is attached by a fleshy tuber or rhizome, cut it as close to the mother plant as you can. Avoid ripping or twisting as the flesh is delicate. Loosen the surrounding soil and lift the pup from the base, keeping any attached roots intact.

Callusing

Set the pup in bright, indirect light for one to three days. The cut end should dry into a firm, matte, corky surface. If the pup has no tuber, only roots, you can plant it immediately, either in a pot or in the ground.

Planting

Place the pup so the base sits on the soil surface. Agaves are prone to rotting at the rosette base, so bury only the roots and tubers.

Early Watering

Water until the soil is damp, then let it dry completely. After that, water sparingly but regularly to encourage new root growth—once a week is a good guide.

Transplanting

When the pup has firm roots and a rich, even color, it’s ready for the ground or a larger pot. Acclimate it to full sun before planting. Water every two weeks for 1-2 months, then let natural rainfall take over. Some agave root in a matter of weeks, while others take a few months.

Bulbils

Bulbils are the second major way to propagate agave. When a mature plant sends up its towering flower stalk, some species produce hundreds of tiny plantlets along the spent bloom stems. 

Not every agave makes bulbils. Species such as Agave americana and A. vivipara are very reliable producers, while others, such as Agave shawii, do not produce any at all.

Harvesting and Rooting Bulbils

Bulbils root easily and with a high success rate. By late summer, as the stalk dries, they typically reach 2–3 inches tall and develop a pale, slightly white base. A gentle tug should detach them; if they resist or feel soft, give them more time.

Tools you’ll need

• Thick gloves (agave can be spiky!)
• Pots of seedling trays with fast-draining cactus soil

Steps:

With your hands, detach the bulbil with a gentle tug. Avoid tearing the base—this is where new roots will emerge.

Callusing

Allow 1-5 days of callusing. Once the base has turned white and looks a little corky, they’re ready to plant.

Planting

Set the bulbil on top of a gritty cactus mix and nestle it slightly into the surface. A coarse, fast‑draining blend prevents moisture from lingering around the base. Pebbles are good for support.

Early Watering

Keep the soil barely moist. Light misting every few days is usually enough until roots form.

Increasing Water

When the bulbil resists a gentle tug or begins producing new leaves, shift to deeper but infrequent watering—about once a week.

Transplanting

When the bulbil has firm roots and a rich, even color, it’s ready for the ground or a larger pot. Acclimate it to full sun before planting. Water every two weeks for 1-2 months, then let natural rainfall take over. Some agave root in a matter of weeks, while others take a few months.

Seed Propagation

Seed propagation is the slowest but most genetically diverse way to grow agave. While pups and bulbils produce clones, seeds introduce variation that strengthens long‑term resilience. Agave seeds are short‑lived, so fresher seed almost always germinates better than older seed.

Seeds develop in pods along the main flowering stalk. Each pod contains dozens of seeds and is ready to harvest when it turns brown and begins to split. Because the stalk can be quite tall, you may need a ladder to safely collect a few mature pods.

Once you’ve collected the pods, the seeds need a short drying period to ensure they store well and germinate cleanly. Fresh pods often hold a bit of residual moisture, and drying helps prevent mold.

• Spread the seeds in a single layer on a paper towel or a clean tray.
• Let them air‑dry for 3–7 days in a warm, shaded spot with good airflow.
• Once fully dry, the seeds should feel firm and papery, not flexible or tacky.

Sowing Agave Seed

Warmth, light, and a gritty, sterile medium are the three pillars of successful germination. Agave seedlings are surprisingly easy to grow when these conditions are met.

Planting in late spring is best. Warm soil (70–85°F) speeds germination and reduces the risk of fungi.

Tools you’ll need

• A shallow tray or small pots
• Sterile, fast‑draining seed mix (cactus mix with added pumice or sand)
• A spray bottle
• A humidity dome or clear cover (optional but helpful)

Steps

Prepare the soil.  

Fill your tray or pots with a gritty, sterile mix.

Sow the seeds.  

Press the seeds gently into the surface. They need light to germinate, so keep them only lightly covered.

Moisten and cover.  

Mist the soil until damp, then cover the tray with a humidity dome. Keep the mix lightly moist—not wet—and vent daily to prevent fungal growth.

Provide bright, indirect light.  

Most seeds germinate within 7–21 days under warm, bright conditions.

Care for seedlings.  

Once sprouted, water from the bottom to avoid disturbing the roots and allow the soil to dry slightly between waterings.

Transplant when sturdy.  

When seedlings have several true leaves and a small root system, move them into individual pots filled with gritty cactus mix. Water them deeply and infrequently, watching for signs of over- and under-watering.

Watch and wait. 

After 1–2 years of steady growth and proper acclimation, young agaves are ready for transplanting into the garden in spring. Acclimate young starts in the same way you would pups or bulbils in early-mid spring.

Wrapping Up

Propagating agave is immensely satisfying. They root well, adapt to their environment quickly, and support a wide range of animal and insect species. Their drought tolerance and range of shapes and colors make them an attractive addition to any garden, and their life cycle means you may never have to buy another agave plant ever again.

Clever Adaptations

Paddle cacti grow in distinct segments that are designed to detach. Each pad is a self‑contained reservoir of water and stored energy, and the joint between pads is a natural break point. Detached pads seal their wounds quickly, resist rot when kept dry, and send out roots with very little encouragement.

Paddle cacti are best propagated in mid-spring when the chance of frost is well past, and the plants have taken in the winter rains, although any season but winter will work with some adaptations.

Choosing a Good Pad

When you’re selecting a pad to propagate, start by looking at the whole plant’s health. A good parent plant will have plenty of mature, thick pads with strong color and clean surfaces. Pads with wrinkles, soft spots, scabs, or signs of past wounds are less suitable.

Age matters too. A pad that’s at least a year old has already adapted to the local climate and built up enough stored energy to support new root growth. Very young pads are still thin and tender, while very old pads can be woody or oversized.

Size is the most reliable factor in choosing a pad. Larger pads can root, but they take longer to settle and are more likely to topple or stay unstable in the soil. In practice, pads between three and eight inches tend to root the most reliably as they are well-sized and not too old.

Removing the Pad

Pads should be carefully removed at the woody join. I have found it easiest to use a clean, sharp garden knife or shears to make a clean cut.

Because paddle cacti have both large spines and much smaller, often near-invisible glochids, take extra care when handling pads. Smooth-ended barbecue tongs are my tool of choice, although many gardeners will also use newspaper or old carpet to carry them. 

Prepping the Pad for Potting

Once removed, every pad needs time to callus. This drying period reduces the risk of rot by sealing the wound into a firm, white, corky surface. Depending on humidity and pad thickness, this can take anywhere from three days to two weeks. A fully callused end looks matte and chalky, with no lingering moisture.

When the pad is ready, plant it in a fast‑draining mix. A gritty soil keeps excess moisture away from the wound and encourages roots to reach downward. A 50/50 blend of sandy native soil and commercial cactus mix works well in my experience because it both feeds the plant and acclimates it to the conditions it will eventually grow in. The pad should sit upright or slightly angled. You may need stakes to support taller pads.

Watering and Early Root Development

Once a pad is planted, the most important thing you can do is not water it. A freshly callused pad contains enough stored moisture to sustain itself for weeks. If the mix stays damp, the pad is less likely to root and is far more likely to rot from the base upward.

For the first two to three weeks, simply leave the pad in bright, indirect light and let the soil remain completely dry. Warmth speeds things along, so a spot that stays above 70°F during the day is ideal. 

After a few weeks, you can test for early rooting by gently pulling on the pad. A pad that has begun to root will feel slightly anchored, as if it’s gripping the soil. If it lifts easily, set it back and give it more time. Once you feel that first bit of resistance, you can begin watering lightly—just enough to moisten the top inch of soil. Then let it dry out completely again before the next watering.

Rooting speed varies by species, temperature, and pad size. Smaller pads often root within two to four weeks, while larger ones may take six or more. The first visible sign of success is usually swelling and deepening color at the top of the pad, followed by the emergence of a new segment. When that new growth appears, you can be confident the plant has established a functioning root system.

In-Ground Planting

When the pad has rooted, acclimate the cactus to the conditions of its final planting location over the course of a week or so, and then plant as you would any other plant. 

A moderate soak once a month for the first 3-6 months will help the cactus naturalize itself to the rainfall in your area, and from then on it should be plain sailing!

Problems to Watch For

Even with good pads and proper soil, a few issues can show up during propagation. These quick cues help you spot trouble early.

• Rot at the base — Softness, darkening, or a sour smell usually means moisture reached the cut too soon. Many pads will survive this, so all is not lost.
• Shriveling — Light wrinkling is normal as the pad uses stored moisture. Deep folds or a limp feel suggest it’s losing water too quickly, often from heat or too much sun.
• Sunburn — Pale, yellow, or bleached patches indicate the pad is getting more sun than it can handle before rooting. Move it to partial shade until new growth appears.
• Instability — Pads that lean or fall over typically haven’t rooted yet or are simply top‑heavy. A small stake helps keep them upright without burying them deeper.
• Slow or no rooting — If there’s no anchoring after several weeks, the cut may not have fully callused, the soil may be too rich, or temperatures may be too cool. Keep it in good condition and keep waiting - it can take months to root sometimes.

Wrapping Up

Working with paddle cacti is incredibly rewarding. After just a couple of years of propagating you can have many more thriving plants, each producing fruit and flowers for you and wildlife to enjoy.
