jojoba Care (Simmondsia chinensis)

This desert shrub thrives in strong sun and is adapted to bright, open sites.

• Provide 6–10 hours of direct sun daily; full sun is best for dense growth and maximum seed production in jojoba.
• Accepts light partial shade, especially with morning sun and light afternoon shade in very hot inland climates to reduce leaf scorch risk.
• In winter, ensure plants are not shaded by buildings or trees; prolonged shade causes leggy, sparse growth and fewer flowers.

This species is highly drought-tolerant and prefers deep, infrequent watering once established.

• Allow soil to dry thoroughly between waterings; in the ground, wait until the top 5–10 cm are completely dry before watering deeply.
• Use fast-draining, sandy or gravelly soil; standing water, sour smell, or yellowing, soft leaves suggest overwatering of Simmondsia chinensis roots.
• During hot, dry periods, watch for dull, slightly curling leaves as a cue to soak the root zone, then let it dry fully again.

This shrub is adapted to hot, arid climates but has some cold tolerance once mature.

• Optimal growth occurs around 75–95°F (24–35°C), with best vegetative activity in warm, dry air and full sun exposure.
• Mature plants tolerate brief drops to about 15–20°F (-9–-6°C), but young plants are less hardy and benefit from protection from hard frost.
• Handles extreme heat above 100°F (38°C) if soil drains well; avoid low spots where cold air settles, which increase frost damage risk.

This desert shrub tolerates low humidity and usually needs no special humidity management.

• Ideal humidity is 20–40%, matching arid or semi-arid conditions.
• Dry indoor air is rarely a problem when caring for jojoba, as long as soil moisture is correct.
• If leaves shrivel while soil stays moist, reduce humidity-raising practices and improve light and airflow.

This species needs very fast-draining, mineral-rich soil that mimics desert conditions.

• Use a sandy or gravelly mix with coarse particles; aim for at least 50–70% sand, grit, or small gravel.
• Keep soil pH slightly acidic to slightly alkaline, around 6.0–8.0, since Simmondsia chinensis is tolerant across this range.
• Combine cactus mix with extra coarse sand or pumice to improve aeration and prevent water staying around the roots.
• Avoid heavy, clay-based, or peat-heavy mixes that compact, hold water, and increase risk of root rot.

This shrub can be grown in containers but needs careful attention to root space and stability.

• Choose a deep, heavy pot to anchor the woody root system and prevent tipping in strong sun or wind.
• Select a container material like unglazed terracotta if extra moisture loss is needed in humid or rainy climates.
• Use a tall container with ample depth so the strong taproot can extend without circling tightly near the base.

This desert shrub has low nutrient demand, so use light feeding only to support container or young plants.

• Apply a balanced, diluted liquid fertilizer (for example 10-10-10 at 1/4–1/2 strength) every 6–8 weeks in spring and early summer.
• Use a small amount of well-aged compost as a surface dressing for jojoba in poor soils, keeping it away from the stem.
• Avoid high-nitrogen products that push lush, weak growth; prioritize slow-release or organic sources for steady nutrients.
• Stop feeding in late summer so new growth hardens before cooler weather and potential winter chill.

Pruning Simmondsia chinensis is mainly structural and corrective, not heavy or frequent.

• Carry out light pruning in late winter or very early spring before new growth starts.
• Remove dead, diseased, crossing, or crowded branches to improve airflow and reduce pest and disease pressure.
• Shorten overly long shoots to maintain a compact, rounded form and encourage branching from lower nodes.
• Use sharp, clean bypass pruners, making cuts just above outward-facing buds to guide future growth direction.

This drought-adapted shrub is usually grown in-ground, so focus on careful outdoor transplanting rather than frequent repotting.

• Transplant in late winter or early spring when temperatures are mild and soil is workable.
• Look for signs such as roots circling the pot, water running off quickly, or reduced vigor as cues a container plant needs more space.
• Move up only 1 pot size, teasing apart circling roots gently and setting the crown at the same depth in a well-drained, sandy mix.
• Water thoroughly after transplanting, then allow soil to dry between waterings and shade the plant lightly for 3–5 days to limit stress.

Simmondsia chinensis is propagated mainly from semi-hardwood cuttings and seeds under warm, controlled conditions.

• Take semi-hardwood cuttings in late spring to summer, 8–12 cm long, and remove lower leaves.
• Dip cut ends in rooting hormone and place in a gritty, well-drained medium kept slightly moist and 70–80°F.
• Sow fresh seeds in warm conditions with good light; germination can be slow and uneven.
• Maintain high airflow and moderate humidity to reduce rot while roots or seedlings establish.

This shrub is fairly cold hardy in arid climates but may need some winter care in cooler or wetter regions.

• Mature plants tolerate light frost, but young or potted plants are more sensitive to prolonged freezes.
• Apply a 5–8 cm layer of dry mulch around the root zone, keeping it a few cm away from stems.
• Grow containers in fast-draining mix; move them under cover or indoors during hard freezes, with bright light and minimal watering.
