March in the Garden
It is said that March comes “in like a lion and out like a Lamb” and although it is only the first week of the month I would say that was fairly accurate – the beginning of the week we were once again plunged into winter and 5 days later the weather is feeling very Spring like, but don’t be fooled as during March winter can be lurking ready to pounce once again! 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 lawn 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.
Sow sweetpeas – in the greenhouse or on sunny windowsill.
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.
Radishes can be sown outside – sow them thinly into drills approx 12mm deeps and 25cm apart.
Parsnips can also been sown outside sow the seed in groups of 3, 15-20cm apart approx 12mm deep and into drills approx 38cm apart – these can then be thinned so that the strongest seedlings remain.
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.
Now is also a great time to sow Seedball the quick and easy way to create your own wildflower patch – Clay ball (plus added chilli) naturally protects seed from predators, such as ants, birds and slugs. Easy to use – no need to ‘plant’, just scatter on top of soil or compost. Ideal for garden beds and planting pots.
Lift and divide summer flowering perennials.
