How to grow jade plant
Overview
Jade plant (Crassula ovata) is a woody-stemmed succulent shrub grown for its glossy, fleshy oval leaves and occasional starry white flowers. It is a popular low-maintenance pot plant in Australian gardens, valued for its ability to thrive with minimal care and its long-lived, sculptural form.
Varieties
- Crassula ovata 'Hummel's Sunset' — Leaves turn golden-yellow with red edges in bright light, popular in Australian pots.
- Crassula ovata 'Gollum' — Tubular, finger-like leaves; a quirky, slow-growing form well-suited to bonsai.
- Crassula ovata 'Tricolor' — Variegated green, cream, and pink leaves; needs bright light to maintain colour.
Soil Preparation
Jade plant thrives in a slightly acidic to neutral pH (6.0–7.0) mix that is extremely free-draining. Use a blend of 1 part potting soil, 1 part coarse sand or perlite, and 1 part pumice. Avoid heavy clay or water-retentive soils; add gravel or crushed granite to improve drainage.
Growing Guide
Plant jade in a free-draining mix of coarse sand, perlite, or pumice with standard potting soil. Position in part shade to bright indirect light, avoiding harsh afternoon sun. Space 30–50 cm apart in garden beds or singly in pots. Allow the soil to dry completely between waterings; water only when the top 2–3 cm of mix feels dry. In cooler zones, grow in a pot that can be moved under cover during frost.
Care
Feed jade plant with a balanced, low-nitrogen succulent fertiliser (e.g., 2-7-7) once in spring and once in summer. Prune leggy stems in early spring to encourage bushiness; remove dead or damaged leaves as needed. Repot every 2–3 years in fresh, well-draining mix to prevent soil compaction.
Companion Planting
Pair jade with other drought-tolerant succulents like aloe, echeveria, or sedum. Avoid planting near moisture-loving annuals or vegetables that require frequent watering, as this can lead to root rot in jade.
Common Pests & Risks
Mealybug scale appears as white cottony clusters on leaf joints and stems; treat with a cotton swab dipped in isopropyl alcohol or neem oil spray. Root rot is caused by overwatering in heavy, poorly draining soil; prevent by using a gritty mix and allowing the pot to dry fully between waterings.
Troubleshooting
Yellow leaves: overwatering or poor drainage; let soil dry out and repot in grittier mix. Brown leaf edges: too much direct sun or low humidity; move to part shade. Dropping leaves: sudden temperature change or underwatering; stabilise conditions and water when dry. Soft, mushy stems: root rot from waterlogging; cut away rotted parts, repot in dry mix, and reduce watering. Leggy growth: insufficient light; move to a brighter spot and prune to encourage bushiness.
