Our RightPlantz March Garden Guide:
Ahh, spring! There is still a chill in the air but we are rounding the corner. March is a busy month and although we still cannot put most vegetables and flowers in the ground, there is plenty to do. Shake of that winter dust and get after it!
Transplant deciduous trees or shrubs. Now is the time to do this task, as long as the soil isn’t frozen or waterlogged.
Strip off any old mulch and add a fresh layer.
Feed ornamental trees and shrubs with a slow release fertilizer.
Feed roses with special rose feed or balanced fertilizer as they begin to grow.
Prune roses to encourage strong new growth. Thin out interior branches.
Prune summer-flowering clematis before they start into active growth.
Finish cutting back dead foliage from perennials and ornamental grasses to make way for new growth.
Prune winter-flowering jasmine (Jasminum nudiflorum) after flowering, to encourage new growth for next year’s blooms.
Keep an eye out for slugs as the weather warms. Pay special attention to soft, new growth, which slugs love.
This month you can plant asparagus, kale, lettuce, spinach, onions and peas.
Cut the old leaves off hellebores to remove any foliar diseases and make spring flowers more visible.
Continue to deadhead winter pansies to stop them setting seed. This will encourage flushes of new flowers throughout the spring.
Deadhead daffodils as the flowers finish and let the foliage die back naturally.
Weed and mulch asparagus beds. Asparagus has shallow roots so weed by hand to prevent damage.
Cut autumn-fruiting raspberry canes to the ground to stimulate new canes, which will fruit in the autumn.
Cut the tips of summer-fruiting raspberry canes that have grown beyond the top of their supports; cut just above a bud.
Feed blueberry plants with ericaceous plant fertilizer.
Apply lime to lawns.
If you do not plan to apply pre-emergent herbicide to your lawn, it is also an excellent time to aerate and overseed.
