In winter, the window sill becomes a dangerous zone for indoor plants: cold comes from the window, and dry heat comes from below, from the radiator. This temperature difference weakens plants, leads to yellowing of leaves and rotting of roots. An easy way to protect green critters is to use foam tiles that create a barrier between the cold surface and the bottom of the pot.
Polystyrene foam does not conduct heat well. It prevents the cold from the windowsill from reaching the roots, maintaining a comfortable temperature for them. At the same time, it protects the plant from the heat of the battery, working as an insulating layer. This is especially important for flowers with sensitive roots: geraniums, ficus, citrus fruits and orchids.
What you will need:
Polystyrene foam tiles 3-5 cm thick (you can use packaging material from equipment);
Ruler and cutting knife;
Trays for pots (if necessary);
Decorative film or fabric (for aesthetics).
Instructions:
Prepare the tiles
Measure the size of the window sill. Cut the foam so that it completely covers the area where the pots are placed. If the plants are different sizes, you can cut out separate stands for each pot.
Organize drainage
Make small holes in the tiles to drain excess water. If using pallets, place them on top of the foam.
Set plants
Place the pots on the prepared surface. Make sure the foam does not block the vents in the bottom of the pots.
Add a decorative touch
If desired, cover the foam with a beautiful oilcloth, fabric or decorative film – this will make the window sill neat.
This method does not require financial costs (foam plastic is often left over from packaging), but it prolongs the life of indoor plants and preserves their decorative appearance even in the harshest winter.
