You don't need a green thumb to transform your humble garden into a field of flowers - or any growing experience at all. As explained by award-winning gardening expert and author Jane Moore, all it takes is a simple job that's ideal to do in March specifically.

It doesn't just look good either. Jane has explained how flowers like snowdrops, irises, sedum, asters are "rejuvenated" by the simple job dubbed "planting in the green". It simply requires splitting up clumps of flowers that will eventually grow and burst into life in the spring. 

In a Youtube video, Jane demonstrates how it's done, saying: "I've also got masses of snowdrops - don't they look great? And that's because I keep dividing and splitting them.

"Snowdrops are one of those bulbs that's best planted when it's actually growing rather than a dry bulb, like daffodils and tulips.

"It's called planting in the green. You can do it any time when the plants have finished flowering - or actually any time when they're actually actively growing.

"But this is the perfect time of year to do it and it's so easy. You simply gently dig up a clump and then tease them apart, then replant the smaller clumps at the same depth.

"If you haven't got snowdrops of your own, they're widely available by mail order. Just make sure that they're coming from a bonafide supplier."

This technique can be extended to other perennial blooms, Jane continued.

"This is the perfect time of year for splitting all sorts of plants. Lots of perennials like irises, sedum, asters. In fact, nearly every perennial I can think of can be divided now to make more plants. It's a great thing to do if you want to have some to give away, but it's also really good for the plants as it sort of rejuvenates them.

"Old plants get worn out and they often just sort of fade away. It's a bit more effort than snowdrops, but just lift the clump using a fork."

Jane showed how it's done with a "lovely" blue aster called King George which she noted is brilliant for butterflies and bees.

"Now the traditional method of splitting it is to use a pair of forks and that's ideal if you're worried about a precious plant because it causes the least amount of damage to the roots."

With a chuckle, she admitted: "But I nearly always end up just chopping it up with a sharp spade and that's always worked perfectly. Then replant where you want them or pot them up to give away, but don't forget to water them in to settle soil around the roots nicely."
