To make your flower beds require less maintenance, you should try to use low water perennials so they can go long periods without water and will tolerate lots of sun.
You should also think carefully about what plants and flowers you’re pairing together - be tactical about it. Try pairing pest-resistant flowers next to tones that are not so resistant which will keep pests and having to use pesticides to a minimum.
If you’re concerned about having to weed your yard, create a raised flower bed that will prevent weeds from growing.
Instead of fussing over buying expensive soil or using fertilizer, make a natural compost using scraps from your food such as vegetables, fruits, and eggs. This will keep your soil rich with nutrients and leave you with happy flower beds.
