Indoor to Outdoor: How to Create the Perfect Microclimate for Your Lavender
Lavender is a tough and beautiful plant, but it’s a bit particular about its environment. It’s native to the dry, rocky soils of the Mediterranean, and to get it to thrive, you need to mimic those conditions, whether you’re growing it on a sunny patio or in a pot on your windowsill.
Creating the right microclimate—a small, specific environment—is the key to a happy and healthy lavender plant.
Outdoor Microclimates: Sun, Air, and Soil
Outdoors is the most natural home for lavender, and a few simple adjustments can ensure it thrives.
- Sunlight is Everything: Lavender needs at least 6-8 hours of direct sun per day. A spot on a south-facing patio, a sunny corner of the garden, or against a sun-drenched wall is ideal.
- Embrace Good Airflow: Lavender needs excellent air circulation to keep its leaves dry and prevent fungal diseases. Avoid placing your pots in a crowded corner. A raised bed or a rock garden can also help improve drainage and airflow around the plant’s base.
- Location Matters: For potted lavender, your biggest advantage is mobility. If you have a wheeled plant caddy, you can move your plant to follow the sun as the seasons change, ensuring it gets enough light no matter the time of year.
Indoor Microclimates: The Challenge of Light and Humidity
Growing lavender indoors is more challenging, but not impossible. The main goals are to provide enough light and control moisture.
- Mimic the Sun: A south-facing window that receives intense, direct sunlight for most of the day is your best bet. If your home lacks a suitable window, you will need a full-spectrum grow light for 10-12 hours a day to supplement the natural light.
- Manage Humidity: Lavender hates a humid environment. Do not place it in a steamy bathroom or kitchen. A spot with good air circulation is key. You can even use a small fan on a low setting to help move the air around your plant.
- The Pot’s Role: For an indoor plant, a terracotta pot is a must. Its porous nature will allow excess moisture to evaporate, preventing the root rot that is the biggest threat to indoor lavender.

Making the Transition
If you plan to move your potted lavender between indoors and outdoors, do so gradually. Acclimate it to its new environment over a week or two by moving it to a partially shaded spot for a few hours a day and slowly increasing its sun exposure. This prevents shock and sunburn, ensuring a smooth transition.
By paying close attention to these simple environmental factors, you can create a perfect home for your lavender, whether inside or out, and enjoy its beauty and fragrance for years to come.
