Pruning Lavenders

It takes most lavenders about three years to fill out and bloom their best.

Cutting then back every year before, or just after bloom, keeps them vigorous and flowering well for many years.

Every third year consider cutting by one-half to two-thirds to keep plants dense and good looking.

Growing Tips

Lavenders love sunshine, so a full sun site is the best. Don’t even consider planting them in shade.

Average, well-drained soil with a pH that’s near neutral to slightly alkaline is a plus.

Loose, sandy soil which provides excellent drainage is critical for healthy growth.

Lavenders are woody-based plants and don’t like to be divided, so it’s best not to do it, since they might not make it then.

Established lavenders can tolerate drought, but they bloom the best if you give them an occasional deep soaking during dry spells. Zones 4-24.

Seasonal Care of Lavenders

Move existing plant clumps if really needed, in early spring. But don’t make a habit of moving them a lot.

Water new plantings regularly if rainfall is lacking.

Once established they are very drought resistant.

Before summer, spread a layer of crushed gravel 1-2 inches deep around each plant to help keep the crown and foilage dry.

It’s generally best to leave lavender plants untrimmed in fall and winter.

Lavenders usually keep their foilage through winter, but may drop their leaves in colder zones.

For protection from winter winds and cold, cover the plants with evergreen boughs.

Pests of Lavenders

Possible pest problem include caterpillars, plant bugs, root rot, and a disease called “shab”, which causes black spot and browned stems. Remove and destroy infected plants.
