Several months into hurricane season, residents of Grand Cayman who have secured homes and businesses may be turning their attention to their gardens. Horticulture during hurricane season requires both strategy and care, especially when strong winds and heavy rains can damage years of cultivation in a single day.
Grand Cayman’s tropical climate allows for lush landscaping and year-round gardening, but it also means that hurricane season — from 1 June to 30 Nov. — poses a significant threat to local flora. Native and ornamental plants alike can suffer damage or loss without proper preparation.
One of the best strategies for gardeners is to prioritise planting native plants. Species such as silver thatch palm, sea grape and buttonwood are naturally adapted to withstand high winds and salt spray, making them more resilient in storms. Incorporating these into your landscape design can reduce the risk of total garden loss during a hurricane.
For existing gardens, pre-storm preparation is crucial. Prune trees and large shrubs regularly to remove dead branches and reduce wind resistance. Secure or bring indoors potted plants and lightweight containers. Trellises, garden décor and other loose items should be removed or fastened down to prevent them from becoming airborne hazards.
Mulching is another helpful step — applying a thick layer around the base of plants can help retain soil moisture and reduce erosion during heavy rains. However, after the storm, be cautious: Floodwaters may carry contaminants, and standing water can promote disease and root rot.
For vegetable and herb gardeners, it is recommended to plant in raised beds and use a well-draining soil to help manage the heavy rainfall typical of storm season. Post-storm, wash off any salt that may have accumulated on the plants but avoid the urge to overwater; plants may already be stressed or waterlogged. Remove damaged foliage and assess for signs of disease before deciding what can be salvaged or needs to be replaced.
The Department of Agriculture often issues alerts and offers advice specific to Cayman’s conditions, so staying informed is key. Local garden centers and nurseries can also be valuable resources for plant selection and storm-proofing advice tailored to Grand Cayman’s unique environment.
While hurricane season can be challenging for gardeners, with careful planning and the use of native species, it’s possible to create a more resilient and sustainable landscape. Gardening in Grand Cayman is not only about beauty but also about building harmony with the natural forces of the region. Preparing your garden today can help ensure it survives tomorrow.
