The last few years have seen gardening rise in popularity. Once considered an activity mostly undertaken by elderly people or retirees, owning, potting and planting greenery has now become a big hit with younger generations. For those who want to up the ante and spruce up their backyard with the latest and greatest in gardening, the trends for next year have just come in, courtesy of The Royal Horticultural Society. The charity has spoken to horticultural experts and science and communities teams, reviewed its own gardens and retail centres to figure out what will be the next big thing in gardening. ‘As we enter a new decade, gardening takes on an ever more important role in helping us to create healthy and happy places to live,’ said Guy Barter, chief horticulturist at the RHS. ‘While many gardeners will celebrate the return of some old favourites there is much to be excited about in the way that we’ll all be growing in 2020.’ From huge plants to 80s flower inspiration, here are the top five developments expected to blossom in 2020. Supersize your plants In 2020, plants will take centre stage in people’s homes. Forget a modest aloe vera plant on your window sill or a spiky cactus. It’s all about big, show-stopping greenery now, like alocasia, which has giant leaves and contrasting stems, and monstera, featuring deep green-patterned foliage. Plants that are around 6-9cm will still remain popular though, so don’t completely overlook miniature shapes if you prefer those. Sustainable soil will become more important Don’t know much about soil? Time to do some research. According to RHS, new findings have revealed that a soil bacteria known as mycobacterium vaccea is good for our immune systems, which could spark interest in mud pies next year. Sustainability is also key, with gardeners expected to use environmentally-friendly materials such as wood fibre and green waste compost. Embrace the ‘no dig’ philosophy, which could help limit damage to soil structure and wildlife. The 80s are back Meanwhile, if you’re considering adding a new flower to your pots, baskets or beddings, the 80s will resurge with nemesia and diascias at the front of the line. The sweet scents will attract bees and butterflies, and new breeding programmes have been introduced which have produced exciting colours, such as the nemesia ‘berries and cream’ style or ‘Wisley vanilla’.
