Most herbs require well drained soil. Many grow in rocky or sandy soil and are adapted to dry conditions. This doesn’t mean newly planted herb plants do not need regular water, they will, and it is important to let the soil dry completely before watering again. The same is true for fertilizing herb plants, they only need a little bit. Herbs are like wine grapes, they are better when they struggle. Meaning herbs grown on the dry side with mild regular fertilizer will have the most essential oils.
Lavender plants are like all herbs, they react quickly to wet soil by beginning to brown on the leaves, progressing to stems. Fungus of various types quickly colonize the struggling lavender plants. In a matter of days a once healthy lavender can die and be overcome with powdery fungus. They really hate wet roots!
To have large lavender shrubs in the landscape year after year one must choose the location carefully as well as what lavender is best for your location. Full sun, a minimum of six direct hours. Protection from winter winds. And a site that allows rain water to drain away quickly. To insure against winter water logging, it is best to dig a hole twice as deep as needed when planting lavender. Back fill to proper depth with sand or gravel under the new plants. This keeps even the wettest winter from killing the plants. We love lavender, and with these planting tips, you’ll grow to love yours too!
