Perennial gardening can be beneficial for many reasons
Low care: Once planted, perennials do not need as much water as annuals since they bloom year after year.
Affordable: While perennials cost more to start out with, they can also save you money in the long run as you won't have to replace them every year.
Environmental advantages: Perennials tend to have more radii than annuals, so they are better for soil health and erosion prevention. They are a habitat for helpful insects and wildlife, too.
Interest all year long: Most perennials have interesting leaves, textured foliage, or flowering blooms that can keep the garden interesting all year long.
To begin perennial gardening in your space do this
Pick a location: Find an area that has good sunlight to grow your plants and drainage.
Choose your perennials: Pick perennials that are suitable for your climate and soil type and will give you the appearance you want in your garden.
Preparing the soil: Tear and till the soil with organic matter like compost to make it more structured and fertile.
Plant perennials: Make holes a bit bigger than your plant root balls, and plant the perennials in the holes as deep as they were in their pots. Water them thoroughly after planting.
Mulch: Add an organic mulch to your plants (shredded leaves, bark) to keep it moist and keep weeds at bay.
Water and fertilize: Be sure to water your plants deeply and regularly especially in dry months. Fertilize them according to their requirements, and never over-fertilize them, as they will grow way too big or won't flower.
Maintain: Keep your perennials tidy and healthy by pruning them. Split them off once every few years so they don't crowd and restore them.
