Lavender is a perennial herb that loves dry and warm growing space. Most often it dies in winter due to lack of care but overwintering lavender is easy if you follow these quick tips.
1. Most of the times lavender plants die off due to the wet and waterlogged soil in winter. Take care to grow your lavenders in a dry well-drained soil.
2. If your soil is heavy add lot of compost, organic matter and sand in it to improve its texture.
3. Grow lavender in the South facing location of your garden as south part remains 5 to 10 degrees warmer in compare to other directions.
4. Cut back the flower stalks down to the leaves when flowers begin to fade so that the plant doesn’t consume its energy in them.
5. Just before frost and winter arrives prune your lavender plant to one third of its height, at least three weeks prior to first frost date to reduce its size and density.
6. When the temperature dip below the freezing point, do heavy mulching and cover lavenders 50-70% with straws and leaves for insulation.
7. Remove the mulch and let the fresh air flow in when all the danger of frost will pass away in spring.

1. To overwinter lavenders growing in pots, move them inside if possible. If you’re using large pots and can’t move them inside, change their location. Place them in a warm and airy spot.
2. Water less, only when top two inches of soil dry out completely.
3. Don’t fertilize in the period of dormancy, mulch your pots heavily before winter arrives.
