Position
Full sun is ideal for Lavender plants to thrive. Lavender plants should be spaced about 1-2m apart. This spacing allows for adequate air circulation and growth, helping to prevent diseases and ensuring each plant has enough room to thrive. If you’re planting a hedge or a larger display, you could space them closer with 1m spacing.
Soil Type
Lavender prefers loose, well-drained soil. Very damp conditions will cause root rot. The ideal pH is between 6.7 and 7.3. If your soil is heavy or clayey, add organic compost or sand to improve drainage. Dig a hole 50cmx 50cm, plant in the hole and fill it with soil. Do not bury the stem. Adding a bit of manure initially will be great, otherwise use Superfrass or rock dust to give them a good start.
Mulching
Use a layer of pine bark mulch around the base of the plant. Mulch helps retain moisture and insulates the roots from heat and cold. Never place mulch on the stem of plants, as this leads to root rot.
Watering
When planting, water the lavender plant deeply. Ensure the soil does not dry out, and water when necessary without overwatering. Once established, lavender is drought-tolerant.
Fertilising
A general fruit and flower fertiliser in spring and autumn will suffice, or apply our slow release fertiliser using 1 teaspoon every 4-5 months.
Pests and Diseases
Aphids, citrus psylla, red scale, citrus greening. Spraying regularly with Agricultural Neem Oil or Effective Microorganisms (EM Control ) will assist in either prevention or after the fact. If you already have aphids or mites, wash the tree with a harsh hosing, and when dry, spray with Neem oil or EM Control.
Practice good garden hygiene (remove fallen fruit and leaves).
Watch for root rot (if overwatered) and fungal infections during wet periods.
Pruning
Lavender needs regular pruning. Pruning keeps the plant compact and encourages healthy growth. In spring, cut back the previous year’s growth to about one-third. After flowers have bloomed, prune lightly to encourage more buds. Avoid heavy pruning in late autumn or winter.
