Spring Gardening Tips - May
Containers & Annual Plantings
- Our greenhouses are loaded! Come see us soon for some colourful annuals!
- Plant annuals out after Mother's Day. Remember to harden them off first by either moving them in at night for a couple of days or keeping them up close to your house for a couple of days before planting. This acclimatizes them so they are not shocked by the night time temperatures.
- Plant up tubs and baskets. Try something new! Our staff in the greenhouses are more than happy to show you their favourites!
- Begin a fertilizing schedule for annuals and perennials in baskets, tubs and beds.
- Lots of Veggies can be planted right away but May 24th is still the 'Old Gardeners' favourite for planting the warm weather veggies into vegetable garden. Tomatoes, cucumbers, zucchinis, corn, beans and basil planted too early have no real advantage so don't be in to much of a hurry to move them outside.
- Apply manure or compost to rhubarb, strawberries, and veggie beds (remember to avoid manure where potatoes will be planted as manure can cause scab on potatoes.)
Veggies Seeds to start in May
- Direct seed in your garden:- beans, beets, broccoli, carrots, cilantro, corn, kale, kohlrabi, leeks, lettuce, green onions, oriental greens, parsnips, spinach, Swiss chard and turnips.
- Start late cabbage indoors.
- Transplant to your garden artichokes, early cabbage, cauliflower, celery and fennel.
- If the nights are warm enough (10 degrees) you can transplant pumpkins, squash, peppers and tomatoes. If the nights are still cool you are best to wait a wee bit.
Borders & Flower Gardens
- Choose and plant summer flowering bulbs, roots, and tubers such as dahlias, lilies, hostas, canna lilies, gladiolas, and many more. These packaged bulbs and roots are a great value!
- Plant roses for gorgeous summer blooms. You can check out our selection for this year on our roses page.
- Plant new trees, shrubs, roses, perennials, pansies, small fruits and hardy herbs. Include bonemeal, peat moss and manure or your own compost when planting and don't forget to water new transplants frequently.
- Feed your garden. We stock a large selection of organic fertilizers which we know you will love! Fertilizing can be easy too! Our bulk 'Organic Mix ' Fertilizer is great for just about everything and is available in a large sack or by the pound.
- Rhododendrons, Azaleas, Heather, Camellias, hedges and other acid loving plants can be fertilized with 'Miracid' or 'Ever Acid' for lovely deep green foliage and for the acidifying that they need.
- Compost or manure can be added to flower beds now.
- Prune early bloomers such as Forsythia after blooming.
- Trim back perennials that have bloomed.
- Hold off trimming down bulbs such as Tulips and Daffodils until the foliage is yellowing as this process is feeding the bulb for next Spring.
- Dead head Rhododendrons and Azaleas as they finish blooming.
- Weed flower beds.
- Clean out pond.
- Repot and/or divide pond plants.
- Choose new water lilies and pond plants now. May and early June are when we find the largest selection of pond plants are available.
- Control moss in lawns with Ferrous Sulphate (Iron) if moss is a problem. You will need two days of dry weather after it has been applied.
- Thatch lawn to remove thatch in older lawns and dead moss in lawns recently treated with moss control. (10 days after moss control.)
- Lime lawns in preparation for fertilizing about two weeks later.
- Feed lawn with a good quality Spring fertilizer.
- Pull dandelions and other weeds from lawn before they flower.
- Seed new lawns and fertilize with Turf Starter 15-30-10.
Whew! You're finished... sit back and enjoy the feeling of a job well done
