As summer concludes, Rock Hill residents are encouraged to begin preparing their landscapes for the cooler fall and winter months. Proper care during this transition period, which is particularly relevant as September begins, can significantly improve plant survival through winter, support local pollinators, and enhance the overall health and appearance of gardens and lawns.
A key task is to continue consistent watering, especially for new plantings, evergreens, and moisture-loving species. Even established trees benefit from adequate hydration, as drought stress can leave them vulnerable to insects and diseases. Removing weeds from gardens and mixed borders now, while temperatures are milder, can reduce the amount of weeding required next spring. This proactive approach helps maintain the aesthetic appeal of areas like those found in the Downtown / Historic District or Woodside Plantation.
Gardeners should not put away their mowers just yet. Lawns should continue to be cut as long as growth persists. A beneficial practice is to mow over fallen leaves, leaving the shredded leaves and grass clippings on the lawn. These small pieces contribute essential nutrients and organic matter to the soil. If leaves are large, a second pass with the mower can further break them down. Additionally, fall leaves can be used as mulch in garden beds, providing insulation for plant roots against temperature extremes, suppressing weeds, conserving moisture, and enriching the soil as they decompose. This also offers winter protection for beneficial insects, toads, and frogs.
Starting a compost pile is another effective way to utilize fall leaves, mixing them with other landscape trimmings. It is important to avoid adding invasive plants, aggressive weeds, or those that have gone to seed. Plant debris infested with insects or disease, or treated with chemicals, should also be kept out of the compost. Materials like fat, meat, or other animal products should not be added, as they can attract rodents. Moistening and occasionally turning the pile will accelerate the composting process, yielding a valuable soil conditioner for future use.
Healthy perennials should be left standing through winter, as they add visual interest with their form and texture to the winter garden. Their seed heads attract songbirds, providing food and adding color and motion to the landscape. These standing plants also offer crucial winter habitats and shelter for beneficial insects that aid in pollination and pest management. However, any diseased plant debris or those infested with damaging insects should be removed from the garden to prevent future infestations, leading to healthier plants and reduced pest control efforts. Local municipalities, including the City of Rock Hill, can provide guidance on proper disposal of such materials.
When cutting back perennials, it is advisable to wait until after several hard frosts. This timing allows the plants to maximize energy production and store it in their roots, promoting robust growth in the spring. Cuts should be made two to three inches above the ground to protect the plant’s crown. To protect gardens from animal damage, barriers such as hardware cloth cylinders, at least four feet high and sunk several inches into the ground, can deter rabbits, deer, and voles. For smaller gardens, a five-foot-tall fence with a secure gate can offer protection from most critters. If fencing is not practical, rain- and snow-resistant repellents can be applied, with greater success achieved before animals begin feeding.
Once fall landscaping tasks are complete, it is a good time to clean, repair, sharpen, and store garden tools for the winter. Lawn mowers should also be winterized. Granular landscape products should be moved to a dry location, and liquid products to a frost-free area, ensuring all are stored securely away from children and pets. Utilizing the cooler fall days for these preparations can help minimize winter damage and streamline gardening efforts when the next growing season arrives. Melinda Myers, a gardening expert and author, emphasizes these practices for a healthier landscape.
