Planting Information

Choosing a Site

Lavender grows best in full sun. These plants are from the Mediterranean and can take heat and dryness. Good drainage is essential for lavender plants, which will develop root problems in poorly drained soil. If your soil needs help with drainage, dig planting holes the size of bushel baskets and mix in generous amounts of small grit gravel or road base. Test drainage before planting. Water should drain in an hour or less.

Soil Prep

Lean to moderately fertile soil works well for lavender. Rich soil contributes to foliage growth and doesn't produce stronger plants nor more blooms. Most soils do not need fertilizer before planting lavender. Soil pH that is neutral or slightly alkaline is ideal for lavenders.

When to Plant Lavenders

Plant lavender outdoors in spring when frost danger has past and soil has warmed. These perennial plants can manage cold temperatures just fine when establish, but during their settling in period they need protection from freezing.

How to Plant

Dig a planting hole a bit larger than the potted rootball of your plant. Situate the plant so that the soil in the pot is level with the garden soil. Refill around plant with soil, tap down to eliminate any big air pockets and water well to settle the soil around the roots. Keep soil lightly moist for the first few weeks while plants are establishing.

Plant lavenders about 15” apart for full size varieties like Hidcote and Otto Quast. Mustead is a dwarf variety that grows to about 18" across so plant is about 8-10"from neighboring plants.

During the Season

Lavender plants need very little care once established. Unless there has been a long period of drought, these perennials typically do not need supplemental water.

Insider Tips

  1. Overwatering is the most common problem people have with growing lavender. Once established, lavender plants generally don't require watering.
  2. Lavender needs to be pruned annually to promote good flower development and to avoid woody stems. Trim plants by one third, using sharp, clean pruners.
  3. The best time to prune lavender bushes is in the spring as plants are starting to leaf out. Do not trim the first year but do prune each spring thereafter.
