What You’ll Need: Glass jars and warm water.

You will need atleast two jars or glasses per plant for this project – the more, the better! Fill with warm water and place them 4-5 inches away from the plant.

As the water cools, it releases warmth and increases humidity – keeping the plants warm in the process.

3. Add Thermal Mass

What You’ll Need: Stones, bricks, or large water bottles.

Pick a sunny spot, like an east-facing window, and keep your plant there. Then, place these objects within 4-5 inches of the pot. During daytime, these will absorb warmth from the sun and radiate it around the plant slowly throughout the day.

Pro Tip: Paint the stones or bricks to match your room’s decor!

PS: Make sure these objects are not touching the windowpane. Also, if you have a room heater, it will work wonders!

4. Group Plants Together

Keeping plants in a close vicinity of each other creates a microclimate, which helps trap humidity and warmth around the plants – keeping them warm and safe from cold drafts.

Pro Tip: Choose a corner, as it helps trap the warmth better and makes a tropical spot inside the room, enhancing the ambiance!

Using traditional string light bulbs helps as they heat up when they are lit, unlike LEDs, which stay cool. Make a coil of these string lights around your pot, and light them up at night. This will help you to keep your beloved plants warm.

PS: Make sure the bulbs are not touching the leaves or stems.
