If you’ve planted flowers or vegetable seedlings that need extra warmth, never fear. Water or stone can warm up the air around those plants.
How it works:
Water Method
DIY “Wall of Waters”:
- Fill milk jugs or plastic water bottles with water.
- Surround your plant with these water-filled containers.
- The water will absorb heat from the day’s sunshine and release it slowly throughout the night, keeping the air around the plants warmer.
Stone Method
Using Stones and Bricks:
Surround your plants with bricks or large stones.
These materials will absorb ambient heat during the day and reflect it onto the plants at night.
Combined Method
Combine both methods by surrounding your plants with both water-filled containers and stones or bricks for maximum heat retention and reflection.
Why we like this:
Using these methods can give you an edge in cooler climates or during slow springs. For example, in Seattle, these techniques can help maintain soil temperatures above 50 degrees, which is crucial for planting tomatoes and other warmth-loving crops.
These simple, cost-effective solutions utilize everyday materials to create a microclimate that supports the healthy growth of your seedlings.
