Perennials are an excellent way to simplify gardening, as they require planting only once and return every year. However, many varieties have a limited flowering period of just a few weeks annually. To enjoy a prolonged blooming season, opt for perennials that produce flowers throughout the summer. This approach allows you to maintain a vibrant garden without the need for frequent replanting.
To make the most out of your perennial collection, consider purchasing a package like the Perennial Flower Garden Collection, which offers a range of flowering plants at an affordable price. For example, you can get a collection that includes Russell Lupine, Black-Eyed Susan, Shasta Daisy, Purple Coneflower, and Blue Columbine for as low as $10. Check out this offer HERE.
When growing perennials, keep the following tips in mind: Plant your perennials as soon as possible after receiving them to ensure they get established quickly. Amend your soil by adding peat moss or compost to improve its structure and fertility. Dig holes that are slightly larger than the root ball of each plant to provide adequate space for growth. Water your perennials regularly, especially during their first growing season.
Finally, in colder climates, consider mulching around the base of your plants to protect them from harsh winter conditions.
