A Special Mix-In for a Garden
If the look of patches of foil in your garden doesn’t appeal to you, then you can try mixing shredded aluminum foil with the mulch and also place some at the base of your plants. One of the benefits of this is that the foil refracts light up into the plant and helps cool the soil around it, thereby retaining more moisture.
It also lights up the parts of the plant beneath where pests such as snails, slugs, and aphids like to hide. Another benefit is that it aids photosynthesis, hence, plant vigor.
