📋 Here’s our top-10 list for indoor and outdoor gardens this May:
1. Direct sow veggie seeds and plant starter veggies according to specific minimum nighttime temperature requirements. Visit us for a full list.
2. Plant herbs. Note: heat-loving herbs such as basil, stevia, and lemon verbena should be planted outdoors when nighttime temps reach 15℃.
3. Plant perennials. Each perennial has its own bloom time, so plant a selection of perennials to enjoy a succession of colour throughout the year.
4. Apply slug bait around your veggie gardens, hostas, and dahlias.
5. Change the colour of your mophead and lacecap hydrangeas. Apply GardenPro Dolomite Lime to soil for pink blooms and GardenPro Aluminum Sulphate for blue blooms.
6. Feed your roses. Apply Orgunique Kelp Boost 0-0-3 to the soil around your roses to help protect them from pests and fungal issues such as black spot and aphids. Also, feed your roses monthly with granular GardenPRO Rose Food (8-14-12).
7. Apply biological controls such as Weevilution to manage root weevils on rhododendrons, hydrangeas, azaleas, primulas, camellias, and strawberries; and apply Attack Pack nematodes for crane flies in lawns or cutworms in gardens.
8. Prune lilacs and rhodos immediately after flowering and feed with GardenPro Rhodo and Azalea fertilizer (6-12-12).
9. Plant annuals for summer colour. Come see us in our 12,000 sq ft bedding plant department for recommendations on the best plants for your garden.
10. Feed hanging baskets and planters with GardenPro Hanging Basket Slow Release fertilizer (14-14-14) and then supplement with Superbloom (10-40-25) every two weeks.
