Ground Cover & Cover Crops: Key to Healthy Gardens
Ground cover plants and cover crops are fundamental to creating and maintaining a thriving, sustainable garden. While both are used to cover soil, their roles differ. Ground cover plants are primarily ornamental and protective, whereas cover crops focus on enhancing soil health and fertility. This article delves into the specific benefits of each, along with detailed guidance on selecting, planting, and managing these valuable plants.
Benefits and Uses of Ground Cover Plants
Ground cover plants are versatile and serve multiple functions in a garden. Beyond their aesthetic value, they play a critical role in protecting soil and reducing garden maintenance.
Erosion Control
Ground cover plants are essential for preventing soil erosion, particularly on slopes and in areas prone to heavy rainfall. Their roots stabilize the soil, reducing runoff and keeping the soil intact.
- Selecting Plants: For erosion control on sunny slopes, choose Creeping Thyme or Sedum, which are low-growing and form a dense mat over the soil. In shaded areas, Pachysandra and Hosta are excellent choices due to their robust root systems.
- Planting Tips: Prepare the soil by loosening it and adding compost to improve drainage and fertility. Plant ground cover in staggered rows to ensure full coverage as they grow. Mulch between the plants to reduce weed growth and retain moisture during establishment.
Moisture Retention
Ground cover plants help conserve soil moisture by shading the soil and reducing evaporation. This is particularly beneficial in areas prone to drought.
- Choosing Plants: Lamb’s Ear and Ajuga are great options, with Lamb’s Ear thriving in sunny spots and Ajuga in the shade. Both plants have dense foliage that effectively retains moisture.
- Planting Guide: Before planting, ensure the soil is well-drained and fertile. Space plants according to their mature size to allow them to cover the soil without overcrowding. Water thoroughly after planting and apply a layer of mulch to help retain moisture.
Weed Suppression
One of the most significant benefits of ground cover plants is their ability to suppress weeds. By covering the soil, they block sunlight, which prevents weed seeds from germinating.
- Best Choices: Hosta and Sedum are particularly effective, with Hosta being ideal for shaded areas and Sedum for sunny, dry locations.
- How to Plant: Clear the area of existing weeds and loosen the soil. Plant your ground cover densely enough to outcompete weeds but not so tightly that air and light can’t circulate. Regularly check for and remove any emerging weeds until the ground cover is fully established.
Aesthetic Enhancement
In addition to their functional benefits, ground cover plants enhance the visual appeal of gardens by adding texture, colour, and interest to the landscape.
- Ornamental Options: Creeping Jenny and Sweet Woodruff are popular for their attractive foliage and flowers. Creeping Jenny is versatile, with bright green or golden leaves, while Sweet Woodruff adds delicate white blooms to shady areas.
- Design Tips: Use ground cover plants to fill in gaps between larger plants, along pathways, or in areas where grass is difficult to grow. Consider mixing different ground covers to create visual interest with varying textures and colours.
