Create a DIY mini greenhouse

Give new life to plastic water bottles by cutting them in the middle and placing the top half (remove the cap) over a pot of the same size or right in your garden bed. That helps protect the plant from insects while also trapping enough sunlight and heat inside to keep the plant warm. Leaving the cap off, especially if the plant is outside, will prevent overheating of the plant as heat gets trapped inside. Two tricks: You can water the plant through the cap-less top. And cut waste by using the bottom half as a pot for indoor plants. Mini greenhouses can be used on both indoor and outdoor plants.
