lavandin

Lavandin (Lavandula intermedia 'Grosso') should be watered deeply but infrequently. During most of the year, it should be watered about once every 7 to 10 days, soaking the root zone thoroughly. In hot summer months, it may need more frequent watering, although the frequency will depend on environmental conditions and plant health. Once the top inch of soil begins to feel dry, it's time to water. Lavandin needs a lot of sun and heat, so it's important to make sure the soil is not too dry. As a rule of thumb, never let the soil dry out completely.

Lavandin (Lavandula intermedia 'Grosso') plants require plenty of full sun exposure throughout the day in order to thrive. The recommended sun exposure for this species of lavender is 8-10 hours per day. Lavandin should be exposed to direct sunlight during the late morning and early afternoon, as the intense heat of the midday sun may cause damage. When in direct sun, the plant should receive protection from wind in order to avoid dehydration and dry soil.

Lavandin (Lavandula intermedia 'Grosso') should be pruned twice each year, once in late winter and again in late spring. In late winter, remove up to 1-third of the plant’s branches, being sure to leave enough of the strong, healthy wood to prevent drying out. This pruning encourages a strong and bushy habit of growth and promotes larger, more fragrant flower heads. In late spring, after the plant has finished flowering, prune off the spent flowers and any weak or damaged branches. This will help promote new growth and encourage the development of flower spikes for the next season.
