How To Care For Dying Lavender Plants. Dry gravelly and alkaline soil is the best option to plant lavender. Lavender also may lose limbs as it ages.
Tie a bunch using a rubber band and hang it upside down in a dark dry place for about a week. Thorough pruning right after flowering ends helps to rejuvenate an aging plant. This is why dry and sandy substrates that dont retain water are recommended.
In areas where lavender has died or is dying due to poor drainage or flooding but where dry conditions are the norm consider replanting it into raised beds as is done on lavender farms.
Keep the mulch away from the crown of the lavender plant however to prevent excess moisture and root rot. In winter keep the containers fairly dry maybe in a cold greenhouse or in the rain shadow at the base of a wall to keep off excessive rain which will help improve the plants tolerance to cold weather. Plant lavender 2 to 3 feet apart. Tie a bunch using a rubber band and hang it upside down in a dark dry place for about a week.
