March in the Garden
It is said that March comes “in like a lion and out like a Lamb” and due to the extremely wet and windy winter we’ve had I’ve no doubt that we all hope this is true. The arrival of March brings with it the beginning of spring and although winter was very wet it has been mild so once the sun does break through the warm rays of spring should arrive fairly quickly but beware as the sunny days can make way for hard frosty nights. March is a great time to get on top of the garden before the weeds take hold and begin to take over.
Grass cutting can begin again this month but remember for the first few cuts set the blades on the highest setting and gradually reduce the height.
Bare patches on lawns can be reseeded now.
Remove dead thatch from your lawn – using a spring tined rake pull it vigorously all over the lawn, this might make it look shabby but it will soon recover and look better than before.
Trim lawn edges.
Gladioli can be planted outside this month it’s a good idea to stagger the plants of the corms as this will extend the flowering period.
Dead head spring flowering bulbs and leave daffodil foliage for at least 6 weeks after flowering.
If you didn’t do so last month prune your roses.
Cut down any perennials that were left over winter.
Start your Dahlia tubers – pop the tuber into a pot or a deep tray and cover with compost ensuring that just the top and any new shoots are just visible, water thoroughly allowing excess water to drain then pop in a warm sunny position.
Prune winter jasmine once it’s finished flowering and hard prune summer flowering Clematis.
Divide snowdrops – once snowdrops have finished flowering it is the best time to move and divide overgrown clumps.
Weeding is a tedious and laborious task but by getting on top of those little weedlings now will prevent them from getting stronger and reproducing, remember “One year’s seeding makes seven years’ weeding”.
If you have a greenhouse then the sowing of many seeds can begin, however, for those without and providing the ground isn’t waterlogged here are a few hardy annuals which can be sown outside – Californian poppy, Cornflower and Cerinthe.
Lift and divide summer flowering perennials.
