Common Gardening Errors That Will Hinder Your Lavender Harvest
By DEIRDRE MUNDORF
Pruning
Cutting the woody portions while pruning can damage your lavender plant. You should only cut the green stems, staying about three inches away from the woody portions.
Another thing to avoid is pruning at the wrong time. You should prune lavender just after the flowers have stopped blooming, which is near the end of summer or early fall.
Make sure you choose the right type of fertilizer for this flower. Opt for a slow-acting, alkaline fertilizer with a low nitrogen count and acidity level.
The ideal soil for lavender, whether you’re growing it in your garden or pots, should have a pH between about 6.7 and 7.3. It should also be well-drained.
For an indoor plant, check the moisture levels by dipping your finger down into the soil a bit to see if it is wet or dry. Water your lavenders only if the soil is dry.
