Gap filling in your flowerbed: A guide to using groundcovers


When it comes to gardening and landscaping, flowerbeds are a popular choice for adding beauty and color to outdoor spaces. However, maintaining flowerbeds can be a challenge, especially when it comes to filling in gaps between plants. These gaps not only detract from the overall aesthetic appeal of the flowerbed, but they can also lead to weed growth and soil erosion. One effective solution to this problem is using groundcovers.

Groundcovers are low-growing plants that spread quickly and densely, providing a natural and attractive way to fill in gaps in flowerbeds. They not only help to prevent weed growth and soil erosion but also add texture and interest to the garden. In this guide, we will explore the benefits of using groundcovers in flowerbeds and provide tips on selecting and caring for these plants.

The Benefits of Groundcovers

Groundcovers offer several advantages when it comes to filling in gaps in flowerbeds. Here are some of the key benefits:

  • Weed suppression: Groundcovers form a dense mat that helps to suppress weed growth, reducing the need for frequent weeding.
  • Soil erosion prevention: By covering the soil surface, groundcovers help to prevent erosion caused by wind and water, keeping the soil in place and protecting the roots of neighboring plants.
  • Moisture retention: The dense foliage of groundcovers helps to retain moisture in the soil, reducing the need for frequent watering.
  • Attractive appearance: Groundcovers come in a variety of colors, textures, and growth habits, adding visual interest and beauty to flowerbeds.
  • Low maintenance: Once established, groundcovers require minimal care, making them an ideal choice for busy gardeners.

Selecting the Right Groundcovers

Choosing the right groundcovers for your flowerbed is crucial for ensuring their success. Here are some factors to consider when selecting groundcovers:

Light requirements:

Different groundcovers have different light requirements. Some thrive in full sun, while others prefer partial or full shade. Assess the amount of sunlight your flowerbed receives throughout the day and choose groundcovers that are suitable for those conditions.

Soil type:

Groundcovers have varying soil preferences. Some prefer well-drained soil, while others can tolerate clay or sandy soil. Consider the soil type in your flowerbed and choose groundcovers that are well-suited to those conditions.

Growth habit:

Groundcovers can be classified into three main growth habits: spreading, clumping, and trailing. Spreading groundcovers quickly fill in gaps by sending out runners or stems that root and form new plants. Clumping groundcovers grow in dense clumps and slowly spread over time. Trailing groundcovers have long stems that cascade over the edges of flowerbeds or containers. Choose a growth habit that suits your aesthetic preferences and the size of the gaps you need to fill.

Maintenance requirements:

Consider the maintenance requirements of different groundcovers. Some may require regular pruning or trimming to keep them in check, while others are low-maintenance and require little to no pruning. Choose groundcovers that align with the amount of time and effort you are willing to invest in their care.

Compatibility with existing plants:

Ensure that the groundcovers you choose are compatible with the existing plants in your flowerbed. Consider factors such as height, spread, and growth rate to ensure that the groundcovers will not overshadow or outcompete the other plants.

Caring for Groundcovers

Once you have selected and planted your groundcovers, proper care is essential for their success. Here are some tips for caring for groundcovers in your flowerbed:

Water newly planted groundcovers regularly to help them establish a strong root system. Once established, most groundcovers are drought-tolerant and require minimal watering. However, during dry periods, it is important to provide supplemental irrigation to prevent wilting.


Applying a layer of mulch around the base of groundcovers helps to conserve soil moisture, suppress weed growth, and regulate soil temperature. Use organic mulch, such as wood chips or shredded bark, and apply it to a depth of 2-3 inches.


Regular pruning helps to maintain the shape and size of groundcovers and prevents them from becoming overgrown. Prune back any dead or damaged foliage and trim back any stems that are encroaching on neighboring plants or pathways.


Most groundcovers do not require regular fertilization. However, if the plants show signs of nutrient deficiency, such as yellowing leaves or stunted growth, you can apply a slow-release, balanced fertilizer according to the manufacturer’s instructions.

Weed control:

While groundcovers help to suppress weed growth, occasional weeding may still be necessary, especially in the early stages of establishment. Regularly inspect the flowerbed for any weeds and remove them promptly to prevent them from competing with the groundcovers for nutrients and space.


Filling in gaps in your flowerbed can be a challenging task, but using groundcovers can provide an effective and attractive solution. Groundcovers offer numerous benefits, including weed suppression, soil erosion prevention, moisture retention, and low maintenance. By selecting the right groundcovers and providing proper care, you can enjoy a beautiful and well-maintained flowerbed year-round. So, next time you notice gaps in your flowerbed, consider using groundcovers to fill them in and enhance the overall beauty of your garden.
