Timely Garden Tips For March

Hold on to your hat, there is a ton of work to be done this month. You may need to quit your day job just to keep up!

If the soil is workable, dig in a 2” (or more) layer of composted leafmold or well-rotted manure into your beds to prepare for the growing season ahead.

Plant bare root roses.

Feed trees, shrubs and hedges with a slow-release fertilizer. Follow instructions on the package.

Plant summer-flowering bulbs such as Gladiolus, Lilies, Elephant Ears and Ranunculus into beds, borders and containers.

If any of your garden plants will need supporting this year, put the supports in now so the plants grow up through them. Adding supports afterwards is difficult and often looks unattractive.

Cool season annuals can be planted now. See our blog post 5 ANNUALS FOR SPECTACULAR EARLY SPRING COLOR for some helpful information.

Prune early-flowering Clematis once their flowers have finished and summer-flowering Clematis before they start into active growth.

Finish cutting back any dead foliage left on your perennials and ornamental grasses to make way for new growth.

Cut off the old leaves of Hellebores to remove any foliar diseases and make the spring flowers more visible.

Deadhead daffodils as the flowers finish and let the foliage die back naturally.

Dead-head Hydrangeas before new growth appears. Cut to about one third of last season’s growth.

Prepare vegetable seed beds by removing all weeds and forking in plenty of compost. Cover prepared soil with sheets of black plastic to keep it drier and warmer in preparation for planting.

Plant asparagus beds from crowns. Weed and mulch existing asparagus beds. Asparagus has shallow roots so weed by hand to prevent damage.

Plant onion, shallot and garlic sets provided the soil isn’t frozen or waterlogged. Alternatively pot up sets into individual pots for transplanting outdoors later on.

Remember to feed your blueberry plants with ericaceous plant fertilizer.

Top up raised beds with compost and good quality topsoil.

Begin weeding as the weather warms – weeds are more easily controlled if removed young.
