Lavender Plant Profile and Growing Notes
Lavender comes in many forms and is a very hardy plant. Aromatic, long flowering and a great hedging plant. Best grown in a sunny position in a humus rich well drained soil, lavender can be planted from autumn right through until early summer, or even later given some water until established. Lavandula 'Sidonie' is a hybrid, 'bred in Australia' and is a variety best suited to warmer climates.
The best time to plant is is early autumn or in early spring, the soil is still warm, or warming up so you will get some root growth. You will not need to water a lot, and the plants should be established before the heat of summer.
As for fertilizer, these plants do not usually require a lot of fertilizer, however that will depend on the soil, a slow release fertilizer in early spring is a good idea. Mulch at the same time. Although lavender will grow in containers it is happiest in the ground. Fertilize every 12 months in spring for great results.
Lavender plants are fairly long lived, around 10 -15 years before they need replacing. Regular pruning will increase the useful life.
Pruning is easy and is best carried out starting when plants are still young, to encourage bushy growth. In general, prune the plant back by 30% in spring. Dendata species require little pruning at all except for a tidy up after flowering.
