Whether you are looking to use ground cover plants for smother weeds in your yard and gardenprevention of soil erosion, for aesthetic purposes or using the plants as an alternative to grass in your outdoor spaceyou want to plant them at the right time of year to allow them to become established and thrive. While there are many ground cover plants to choose from, each with their own care requirements, overall the ideal season for planting them is spring or early summer. Placing them in their proper place early in the year will give these perennials time to take root and spread to the desired area before winter. Note that if you choose early summer, be sure to provide your plants with enough water as the days become hotter and longer.

That said, early fall sowing is not out of the question. Although spring or early summer is best, placing your ground cover plants in their proper place at this time of year could still give them plenty of time to take root before winter. Frequent rain this season may reduce the time you need to water these plants to help them get established as well. Plus, you’ll avoid the summer heat, which can be harsh on new plants. But before you put your ground cover of choice in your garden or yard, you need to do some prep work to give your plants the best chance of survival.

First, remove all weeds from the area. You don’t want other plants competing for nutrients while your ground cover is trying to make the space its new home. Also make sure your soil meets the nutritional and pH specifications of your chosen ground cover. Tests can be carried out using kits purchased from garden centers, do a DIY test to check the health of your soilor contact a professional by contacting your local university extension. Once you have the results, make the necessary adjustments to meet the needs of the plant. Or you can simply add a complete 10-10-10 fertilizer to the soil without testing, mixing it about 6 to 8 inches deep.

You also want to make sure your soil drains well but retains some moisture for your plants. Clemson Cooperative Expansion suggests working in compost at least 8 inches deep in the desired area. This will facilitate drainage while improving the soil’s ability to retain some water.

Once the preparation is complete, it’s time to plant. Pay attention to spacing, allowing enough room for your ground cover to spread while avoiding overcrowding. A good rule of thumb is to look at the extent of their scope over three years and space them accordingly. Also remember that spring is the time when many plants grow, including weeds. Staying on top of weeding and removing all invaders early in their growth cycle is key to the success of your ground cover. A few inches of mulch might help in this area. Although spring rains can help, you want to water your plants regularly whenever the soil is dry.
