Lavender is a beautiful perennial shrub valued for its fragrant purple flowers and gray-green foliage. It’s versatile, used in teas, cocktails, and essential oils found in soaps and cosmetics. Its soft, calming aroma makes it a favorite among many.
Growing lavender indoors can be challenging, so follow these tips for the best results.
Where Should I Place My Lavender Plant Indoors?
For successful indoor growth, lavender needs as much light as possible. It thrives in a south-facing window or a spot with at least three to four hours of direct sunlight. Even better, use an LED grow light to provide consistent, full-spectrum light all year round. Rotate the pot weekly to ensure uniform growth and flowering. Without adequate light, lavender will develop weak, leggy growth, stop flowering, and become more susceptible to diseases. Good ventilation and air circulation are essential indoors, but avoid placing the plant near forced-air heat sources.
Ideal indoor temperatures from spring through mid-fall are 50 to 55°F at night and 70°F during the day. From late fall through winter, cooler temperatures are preferred: 45 to 50°F at night and 60 to 65°F during the day. Lavender also benefits from being moved outdoors to a semi-shaded area after the danger of frost has passed. In spring, it can be planted outside in a sunny spot. When mature, lavender can withstand temperatures as low as 10°F.
How Much Water Does My Indoor Lavender Plant Need?
Water your lavender thoroughly, allowing the soil to dry slightly between waterings. Check moisture levels by touching the soil with your finger. Avoid overwatering or letting the soil remain constantly moist, as this can lead to root rot. However, do not let the soil dry out completely, as this can cause yellowing of the lower leaves. If you move lavender outside in spring, keep in mind it will dry out faster and will need more frequent watering.
Do I Need to Prune My Indoor Lavender Plant?
Harvesting flowers by cutting branches encourages new growth and helps the plant look fuller. Occasionally tip prune if you want a bushier plant, but note that flowers grow at the tips of branches, so frequent pruning may reduce flowering.
How Often Should I Fertilize an Indoor Lavender Plant?
Fertilize with a water-soluble, all-purpose fertilizer at half strength every four weeks during the spring and summer.
What Type of Soil Does My Indoor Lavender Plant Need?
Lavender thrives in well-drained, slightly gritty soil and does not do well in heavy clay. For indoor growth, use high-quality potting soil mixed with a bit of cactus mix. Repot your indoor lavender plant every year or so to keep it healthy.
