Tips for growing lavender include choosing a variety suitable for your climate, choosing a good location to grow the plants and properly preparing the soil before planting. Growing lavender in full sunlight on well-drained, alkaline soil, maintaining a reasonable water schedule and pruning the plants annually are recommended lavender-growing tips as well.
To make sure the soil is not too moist, it is best to plant lavender in raised beds. Mixing stones into the soil may help to keep it well-drained. In the flowerbed, it is best to form a raised mound with a hole in the middle for each plant and to make sure the mounds are spaced enough to accommodate full-grown plants. A mixture of equal parts of lime, bone meal and composted manure helps to raise the pH level of the soil and gives the plants needed nutrients. Each plant needs half a cup of this mixture placed on the bottom of the planting hole. After the planting, mulching with light-colored stones or shells can help to reflect light away and keep the soil as dry as possible.
Most seasons of the year are suitable for planting lavender, with exception of very dry and cold periods. During the first two years, the plants need to regular watering with the equivalent of at least one inch of rainfall each week. Growers should take care not to give the plants too much water, however, as over watering can be more dangerous than drought.
Prune lavender plants once a year. The best time for pruning is in late winter, when the temperatures stat to rise. A well-pruned plant has two to three inches of the green part of each branch left after cutting.
