Lavender - Key Growing Information

Field of lavender of a winter-hardy type that will produce bushy, well-branched plants and flowers the first year.

DAYS TO GERMINATION:

14-21 days at 65–70°F (18–21°C).

SOWING:

Transplant (recommended): Sow seeds 1/8" deep in a flat 8-10 weeks before the last frost. Seeds require some light for germination. Transplant to individual pots when the plants are large enough to handle. Transplant to the field in the spring after the last frost. Plant shallowly, so the soil line is just above the top roots of the plant. Space plants 12-18" apart in rows 24-36" apart. In late fall, clip plants back to below the flower stems and mulch heavily. During the second year, cuttings can be taken from August-November, when the stems are semihardened, but before they have been subjected to a hard freeze.
Direct seeding is not recommended.

LIGHT PREFERENCE:

Sun.

SOIL REQUIREMENTS:

Plant in a light, well-drained, gravelly soil. Lavender likes a protected, south-facing location. Soil that is slightly acidic to slightly alkaline is most desirable. If the soil pH falls below 6.5, the soil should be treated with lime to adjust the pH to no more than 8.3.

PLANT HEIGHT:

12-18".

PLANT SPACING:

12-18".

HARDINESS ZONES:

Varies.

HARVEST:

Harvest the flower spikes on a dry, warm, sunny day just as the flowers are about to open. Hang to dry in a dry, well-ventilated space out of direct sunlight.

SCIENTIFIC NAME:

Lavandula angustifolia
