When Can Lavender Seedlings Go Outside?

Lavender is a popular plant that adds a beautiful fragrance to any garden or indoor space. It is easy to grow from seed, but many people wonder when to transplant their lavender seedlings outdoors. In this article, we will explore when lavender seedlings can go outside and how to ensure their success in the garden.

Best Time to Transfer Lavender Seedlings Outdoors

Indoor Start

If you started your lavender seeds indoors or in a greenhouse, you should wait until the seedlings have reached a height of approximately 3 to 4 inches before transferring them outside. This typically takes 8 to 10 weeks or more after planting the seeds.

Outdoor Sowing

If you directly sowed lavender seeds outdoors, you should wait until the seedlings have grown big enough to withstand transplanting. This takes about 4 to 6 weeks after the seeds have germinated.

Factors to Consider

When transferring lavender seedlings outside, it is important to consider several factors that could affect their growth and survival:

• Temperature: Lavender prefers warm and sunny conditions. Wait until the last frost has passed in your area and nighttime temperatures are consistently above 50°F (10°C).
• Soil: Lavender thrives in well-draining, alkaline soil with a pH between 6.5 and 7.5. Amend the soil with sand or gravel if necessary to improve drainage.
• Location: Choose a location that receives full sun or at least 6 to 8 hours of direct sunlight per day. Lavender also appreciates good air circulation and protection from strong winds.

How to Transplant Lavender Seedlings

When transplanting your lavender seedlings outdoors, follow these steps:

1. Water the seedlings well the day before transplanting to help prevent shock.
2. Dig a hole that is slightly larger than the root ball of the seedling.
3. Gently remove the seedling from its container and loosen the roots if they are root-bound.
4. Place the seedling in the hole and backfill with soil until the plant is at the same level as it was in its original container.
5. Water the plant deeply but avoid getting water on the leaves or stem.
6. Mulch around the plant with gravel or other organic material to retain moisture and suppress weeds.

Lavender seedlings can go outside when they are strong enough to handle the transition and when weather conditions are favorable for their growth. Whether you started your lavender indoors or sowed it directly outdoors, wait until the seedlings are big enough and follow the tips we mentioned for a successful transplant. Lavender is a low-maintenance plant that rewards gardeners with its beautiful blooms, soothing fragrance, and myriad uses in cooking, aromatherapy, and more.
