Seaweed compost and bean ‘manure’ among RHS garden trends for 2023 | Gardens


The Royal Horticultural Society predicts seaweed compost supplements and ‘compost’ made with beans will be one of the top garden trends for 2023.

As regenerative gardening becomes fashionable, experts at horticultural charities are demonstrating how to grow beautiful plants in a greener way that protects the soil rather than extracting it from the soil.

People will also learn to lure creatures that were previously vilified as pests into their gardens, bringing them unexpected benefits. , said it has received more inquiries about encouraging more wildlife to enter the garden. These include hornets that prey on caterpillars, slugs that help recycle decaying material, aphids that feed ladybirds, and lacewing and hoverfly larvae.

Dr. Mark Gush, Director of Environmental Horticulture at RHS, said: In our gardens we apply no-tillage techniques, use cover crops and apply mulch to ensure that the soil on which growth is based is nurtured and protected. It releases nutrients, minimizes evaporation and regulates temperature throughout the year. ”

Home composting has long been a favorite of many gardeners and those aspiring to zero-waste homes.

Matthew Pottage, curator of one of the charity’s gardens in Surrey, said: We stopped digging the garden and allowed the leaves to sit on the beds. We now have a better understanding of soil ecosystems and their benefits for plants.

“Since we opened the World Food Garden using regenerative horticulture, it has been a huge success. Retention has improved. Following these very positive results, we are moving to the same system in our orchards.”

This year’s drought in the UK has made gardeners more aware of the need to protect plants from prolonged dry weather. weather. “

Other ways RHS has predicted that gardeners can future-proof their space for extreme weather include gravel gardens and “xeriscapes” (designed to minimize future watering). garden). There are some plant permutations a gardener can make to maintain the same feel, such as substituting choisha for hydrangea and figilius for fuchsia.

Gardeners also plan to make their properties flood-proof, and with hard landscape costs skyrocketing, RHS predicts that gardeners will turn to plants to add structure to their patches. Green walls, hedges and swimming ponds are all expected to grow in popularity. Searches for myrtle on the RHS website increase by more than 500% in the fall, making the fragrant evergreen shrub suitable for Mediterranean borders, hedgerows and screens.

RHS Chief Horticultural Scientist Guy Barter said: In the coming year, we expect gardeners to garden more with nature and the environment in mind than ever before, a trend that is growing each year and will be a major concern for gardeners in the UK. ”
