How To Grow Lavender Indoors

Lavender indoor plants are usually easy to grow only when you provide them with the growing environment they demand. Following are the ideal caring tips for your lavender plants.

Light Conditions for Your Lavender Plants

When placed outdoors, the lavender plants thrive well in full sun, so they want as much sunlight as possible when placed indoors. For indoor lavender plants, bright sunlight will work best. A window where your plant can get at least three to four hours of direct light every day is important for better growth.

Temperature Requirements for Your Indoor Lavender Plants

The temperature needs for lavender plants are slightly different when grown indoors. They need one temperature range to grow well at night and one for growing better in the day. Such differences in their temperature will increase more flowering and promote robust and healthy foliage growth. Between spring and mid-fall seasons, ideal temperature ranges between 21°C (70°F) during the day and 10-13°C (50-55°F) at night. In the late fall season through the winter, temperature ranges must be 15-18°C (60-65°F) during the day and about 7-10°C (45-50°F) at night.

Humidity For Your Lavender Plants

Unlike tropical indoor plants, lavender plants prefer a low humidity environment and are great in warm, dry conditions. The indoor home environment has relative moisture levels of around 40%, best for growing your lavender plants. It eliminates the need to add extra humidity or grow them in your bathroom for enhanced humidity levels.

Watering Your Lavender Plants Indoors

Lavender plants are native to the Mediterranean and love to stay drier, opposing plants like their roots to hold moisture. The potting soil should dry before watering again, but you shouldn't let it dry as it will cause yellowing of the leaves. Overwatering your potted lavender plants will trigger root rot and jeopardise the entire plant. Check the moistness of the soil by inserting your finger in the top one inch of the soil. If the soil is completely dry water, it again.

Fertilising Your Lavender Indoors

Your lavender plants can survive well in poor fertilizer conditions. That’s because too much fertiliser inhibits flowering and encourages vegetative growth. To avoid over-fertilisation, you can apply well-balanced, water-soluble fertilisers designed at half the recommended strength in the growing season. Also, this can be utilised in the late summer or even in the early fall.

Pruning or Harvesting Your Lavender

It would help if you pruned your lavender plants after their first flowering. Also, in fall, you need to prune them again before their growth slows in the winter months. First, you need to remove around two-thirds of your plant from the bottom two sets of plant leaves present on the stems. You need to be careful and avoid cutting the woody part of your lavender plants. To enhance the bushy growth, you need to pinch back your plant's tops as required during its growing season. If you want to harvest your lavender flowers right after their opening, you need to cut them using a pruner or a sharp pair of scissors in early spring. Collect the stalks and cut them around two inches above your plant’s woody growth.
