Ocotillo

Ocotillo key facts

Growing Difficulty

Intermediate

Lifespan

Long-lived shrub taking 60–100 years to mature

Size

2.5–6 m (rarely 10 m) tall; stems about 6 cm thick at the base

Watering

Light feeding in the growing season

Light & Placement

It grows best in full sun to part shade.

Watering

Give moderate water while it is in leaf and keep it dry while it is leafless and dormant.

Soil & Repotting

A plant of dry rocky ground: use a free-draining mix. Seedlings grow fast and need a deep pot for their stout taproot.

Pruning & Shaping

To show off the swollen base, side branches are often pruned away to enlarge the main trunk.

Propagation

Propagate from seed or cuttings; in its native range cut stems used as fencing often take root to form a living fence.

About Ocotillo

Fouquieria splendens (ocotillo) is a North American desert plant with spiny stems that leaf out after rain and bear red tubular flowers. In the wild it is a shrub 2.5 to 6 meters tall.

7 things to know before growing Ocotillo

1. 1Light & placement

   Ocotillo thrives in strong, direct sun, so an all-day sun spot outdoors suits it best. If kept indoors, place it by the brightest south-facing window you have and make sure air circulates around it.

2. 2Watering rhythm

   While the plant is actively leafing out, water thoroughly whenever the topsoil dries. Once it drops its leaves and enters dormancy, cut back watering sharply and keep it on the dry side.

3. 3Fast-draining soil

   A well-draining cactus or succulent mix suits ocotillo well. Blending in pumice or hard akadama helps ensure the drainage that keeps roots from rotting over the long term.

4. 4Repotting

   Repot every few years during dormancy to prevent the roots from becoming pot-bound. The roots are delicate, so work quickly, and hold off on watering for a while afterward to let them recover.

5. 5Seasonal care shifts

   Care needs change dramatically between the growing season and dormancy. Give it plenty of sun and water while it's in leaf, then switch to a drier, cooler regimen once it drops its leaves for the season.

6. 6Choosing a healthy plant

   Look for a plant with firm, unwrinkled stems, since shriveling can signal dehydration. The condition of the spines and the base of the stems is another good health indicator, and during the leafing season, good leaf coverage is a useful sign too.

7. 7Cold protection & winter

   Ocotillo enjoys heat but doesn't tolerate cold well, so bring it to a bright spot indoors as temperatures drop. Keep it on the dry side through dormancy so it winters over without excess moisture.

Frequently asked questions about Ocotillo

Q.Is it normal for the leaves to appear and drop repeatedly?

A.This isn't a sign of disease — it's simply how ocotillo behaves naturally. It flushes with new leaves within days of rainfall, then drops them again and goes dormant as conditions dry out.

Q.Can it be grown indoors?

A.Yes, it can be kept indoors as long as the spot gets plenty of light and airflow. It's hard to match the intensity of outdoor direct sun indoors, though, so place it at the brightest window available.

Q.When does it bloom?

A.During its active growing season, clusters of red tubular flowers appear in spikes at the stem tips. Whether and when it flowers can vary depending on the individual plant's condition and growing conditions.

Q.Is this suitable for beginners?

A.It's generally considered an intermediate-level plant to grow. Because watering needs to shift dramatically between the growing season and dormancy, prior experience with succulents or cacti will make it easier to manage.

Q.How large does it grow?

A.In the wild it typically reaches 2.5 to 6 meters tall, occasionally as much as 10 meters, with stems around 6cm thick at the base.
