Lavender is a fragrant herb that produces small purple flowers. It has many uses, such as relieving migraines and depression, but is best known for the relaxing effect of the fragrance. Lavender also helps ease stress and promote sleep. It can easily be grown indoors, and the fragrance will promote a stress-free environment. Varieties like French lavender grow well indoors.
Add soil to a pot that is large enough to hold your lavender plant. The pot should have one or more drainage holes in the bottom. Use loose, well-draining soil with a pH level between 6.5 and 7.0.
Water the soil until water drains from the drainage holes; allow sufficient time for drainage. The soil should be moist, but not soaked.
Dig a small hole in the soil that is large enough to hold the root ball. Barely cover the root ball in soil, and do not position any part of the stem below the soil line.
Place the plant in a warm area where it will receive bright light. If natural light is not available, use artificial lighting.
Water established plants infrequently, and allow the soil to dry out before watering again.
Prune any brown or dying foliage regularly. Prune older growth up to a third of the plant's size in order to make room for new growth.
Fertilize the lavender plant twice a month with a general-use fertilizer that has been diluted to half strength. Do not fertilize the lavender in the winter.
Cut lavender flower spikes just before they open and hang them upside down to dry. Airflow is important to lavender; place the plant near an open window occasionally, or place it outdoors a few times a week. If your lavender has previously been planted outdoors, move it indoors gradually. Start by moving the plant to a location where it receives less light than usual. Then, move it indoors for several hours a day before placing it back outside. Continue the process for a week before moving it permanently indoors. Propagate a lavender plant by dividing an existing plant, or by rooting a cutting taken from an adult plant.
Check the plant regularly for pests by examining the underside of the leaves for any sign of infestation.
