How Do I Move Lavender Without Killing It?

Lavender is not the easiest plant to transplant, but moving one successfully is entirely achievable if you choose the right time of year, prepare the new site properly, and handle the root ball with care. The main risks are disturbing the roots so severely that the plant cannot re-establish before a hot dry period or a cold winter, and replanting into conditions that are no better than where the plant was struggling. Get those two things right and most lavender transplants recover well within a season.

Best time to transplant lavender

Early autumn (September to October) is the preferred window for moving lavender. Soil temperatures are still warm, which encourages rapid root re-establishment, while the cooler air temperature means the shoot system is not under the same high water-demand pressure it would be in summer. Spring (March to April) is the second-best option, before active growth begins and before warm weather increases water demand on a newly moved root system. Avoid moving lavender in the height of summer or in mid-winter when the ground may be frozen.

Preparing the new site

Before lifting the plant, prepare the new planting hole thoroughly. Improve drainage by working in generous amounts of horticultural grit — particularly if moving from one part of the garden to another where soil may be heavier. The hole should be slightly larger than the root ball. If the soil at the new site is compacted or waterlogged, reconsider the location: moving lavender from one poor-drainage spot to another resolves nothing.

Lifting the plant

Water the plant the day before moving to hydrate the root ball and make it easier to lift cleanly. Dig a circle at least 30 cm from the base of the plant to avoid severing main roots. Work the spade under the root ball at an angle to lift the whole mass intact. Lavender has a fairly compact root system that lifts as a ball without spreading far, but digging too close to the crown damages the feeder roots that are most important for re-establishment.

Planting and aftercare

Transplant immediately — do not leave the bare root system exposed to sun or wind for more than a few minutes. Place the plant at the same depth it was previously growing — planting too deeply covers the woody crown in soil and promotes rot. Firm the soil gently around the root ball and water in well. For the first two to four weeks, water once a week if conditions are dry. After the first month, reduce to the minimal watering that established lavender requires.

Reducing transplant shock

Trim the plant back by about one third at the time of transplanting. This reduces the water demand on the shoot system while the roots are recovering. The plant may look sparse for the rest of the season, but this pruning substantially improves the survival rate of transplanted lavender. Avoid feeding the plant in its first season after moving; let the root system recover without the additional demand of processing nutrients.
