Lavandula dentata var. candicans

Spring · Outdoors

Add lime to soil

This plant prefers lime in soil. Where soil is neutral or only just alkaline, give a lime dressing in spring, applied as per rates on the packet.

Spring - late · Outdoors

Give light potash feed

The plant enjoys a sprinkling of potash round its base in spring.

Spring-Autumn · Outdoors

Water in dry periods

Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.

Spring - mid · Planting

Prune young growth

Remove most of the young growth that the plant has made in the previous season. Leave just around 2 centimetres of young growth on the plant. Don't cut into old wood unless it is diseased or damaged.

Winter-Spring · Planting

Protect from winter cold

Bring the plant into a frost-free area before frosts occur, and do not put them outside until all danger of frost is past. Follow watering instructions, or allow the plant a period of dormancy during the winter.

Plants need to be brought inside in cold areas, i.e. colder than zone 8.

Add root growth stimulant to the planting hole

Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.

Planting

Deadhead blooms during flowering season

Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.

The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.
