March

At last, spring arrives, and perfumes and colours are back after the long cold winter ... Did you miss the good smell of earth? March is the ideal time to start working in the garden and on flowerbeds. Here’s a list of things to do:

  • Prune dormant fruit trees
  • Apply dormant oil
  • Indoor seeding of annual flowers and some vegetables
  • Plant canna and dahlia bulbs indoors
  • Fertilize and repot indoor plants
  • Make a garden plan and order seeds

April

Spring has truly arrived! Here are examples of general work to be done in zone 5:

  • Remove winter protections, usually in mid-April (consult us on what to do in early spring and or with extreme temperatures)
  • There may still be time to apply dormant oil and sulfur compound before bud break on fruit trees and ornamental trees to destroy insect larvae and prevent scab and powdery mildew
  • Remove winter-damaged parts of trees, shrubs and roses
  • Prune summer-flowering shrubs
  • Remove suckers
  • Water evergreen shrubs and conifers
  • Remove the brown parts of perennials that weren’t cut back in the fall
  • Fluff up mulch and add more as needed
  • Seed annual flowers indoors and plant bulbs such as cannas or dahlias
  • Clean and inventory tools and equipment
  • Attach supports to plants that need them

May

Warm weather is settling in! However, there is still a risk of overnight frost. Patience is the watchword for the vegetable garden and annuals. Here are some examples of work to be done in zone 5:

  • Control weeds
  • Gradually acclimatize homegrown plants to the outdoors
  • Transplant seedlings before leaf budding
  • Plant purchased plants in beds or containers
  • Hoe and amend the soil of the vegetable garden
  • Add stakes and supports
  • Prune spring-flowering shrubs after flowering
  • Fertilize trees, shrubs, conifers and roses with adequate fertilizer
  • Add compost and mulch to beds
  • Plant onion sets
  • Transplant vegetable seedlings to the garden when the risk of frost is plan or plan to cover at night
  • Get your berry plants and plant them
  • Aerate the lawn and if necessary re-seed
  • It’s already time to monitor for insects and diseases
