As soon as warm weather and sunshine arrive in Southern Ontario, it’s time to head to the garden centre and pick up all the plants we’ve been dreaming about all winter long! May 24th is generally the date we look forward to — the unofficial marker when frosty mornings are behind us and the promise of summer is ahead.
By now, cool-weather plants like cabbage, Brussels sprouts, peas, and lettuce should be well established in the vegetable garden. And for everything else, it’s go time!
TIP: Before you start planting, this is the ideal time to amend your soil. Top up your garden beds with fresh topsoil or enrich them with compost to improve soil health, add nutrients, and promote vigorous plant growth. Don’t forget to refresh the soil in your containers as well, with potting mix or compost.
Warm Weather Vegetables
When soil temperatures are consistently 60°F (15°C) or higher, it’s safe to plant all the warm-weather vegetable crops we’ve been waiting for! Plants that thrive in warmer weather include tomatoes, peppers, eggplants, cucumbers, zucchini and corn.
At Eising Garden Centre, you’ll find vegetables in 6-packs, 4” pots, trellised patio containers, patio bowls and hanging baskets - while supplies last, of course!
Herbs also love warm weather, and tender varieties like basil are safe to plant once all danger of frost has passed. Whether you plant herbs directly into the ground or create a potted herb garden near the kitchen door, they’ll add fresh flavour to your meals all season long. A container of herbs also makes a wonderful gift when visiting friends and family for a summer BBQ.
While you’re in the vegetable and herb aisle, keep an eye out for everbearing strawberries in planters and containers of tropical fruits like lemons, limes, and oranges.
Annual Flowers
Winter-weary flower beds can be revived almost instantly with a burst of colourful annuals! If you’re looking for an immediate impact and blooms that last all summer long, annual flowers are the answer.
Whether you plant them in beds, containers, window boxes, or hanging baskets — or choose from one of our gorgeous pre-planted options — just add water and fertilizer, and you’ll be rewarded with a vibrant display that keeps on giving.
Perennials
While perennials may not bloom all summer, many offer extended bloom periods, and by combining different varieties, you can create a succession of flowers that lasts for months. Perennials also provide essential greenery to anchor your garden and enhance the look of your flowering plants.
You can plant perennials from spring through fall, but getting them into the ground now gives them a strong start. From hostas and ornamental grasses to daisies and delphiniums, there’s a perennial for every style of garden — and the best part is, they’ll return each spring like dependable old friends.
Trees, Shrubs and Vines
Often called “the bones” of the garden, trees, shrubs, and climbing vines add essential structure, height, and seasonal interest. Planting them now allows you to design your garden layers thoughtfully, incorporating annuals and perennials around their base.
Spring is also the prime time to purchase and plant fruit trees and fruiting shrubs. At Eising, spring offers the best selection for starting your home orchard. Are you thinking of adding a few edible shrubs? Gooseberries, haskaps, hardy kiwi, rhubarb and raspberries are excellent choices.
Mulch
Okay, it’s not a plant, but this is a reminder to add mulch to your garden beds or containers. After planting, adding a layer of mulch to your garden beds or containers helps retain soil moisture, reduces transplant shock, and suppresses weeds. Even if a few weeds manage to sneak through, mulch makes them easier to pull.
Water Garden Plants
If you have a garden pond, spring is the perfect time to add water plants. Floating plants, such as water hyacinths and water lilies, help shade the pond’s surface, reducing algae blooms. Marginal or bog plants, such as water iris, papyrus, and cattails, also help keep the water healthy and clear by improving oxygen levels and providing habitats for beneficial wildlife.
Time to Grow!
May is one of the most anticipated and exciting months in the garden. Whether you’re dreaming of fresh vegetables, a lush landscape, or a colourful flower display, planting now sets the stage for a beautiful, bountiful season. Visit us at Eising Garden Centre to find everything you need — and let’s get growing!

Spring is the time of year known for new beginnings, and it’s also a very busy season in the garden as we hurry to get everything planted for the summer growing season here in Southern Ontario. But, did you know that fall is also an ideal time to get planting?
Similar to spring conditions, the cooler temperatures and more frequent rainfall make it easier for new plants to transition. This also decreases transplant stress. There’s time for roots to become established, and by springtime, you’ll be enjoying your plants instead of being busy planting them!
Don’t wait too long, though! At Eising Greenhouses, we recommend planting perennials, trees and shrubs before Thanksgiving weekend to give your new plants a little time to settle in before a hard frost arrives. A hard frost, or freeze, is when the temperature dips below zero for an extended period of time, killing tender plants.
What to Plant in Fall
Spring-Flowering Bulbs
Tulips, Daffodils, Hyacinths, Crocus, Fritillaria and Alliums are just some of the bulbs that need to be planted in the fall in order to enjoy their flowers in the spring. Tulips especially appreciate being planted in cooler weather, but all of these bulbs require a cold period of about 12 weeks in order to grow in the spring. Many bulbs can be planted right up until the ground freezes. But why wait?!
👉 TIPS: While Tulips can be tasty and tempting for squirrels, rabbits and deer, many bulbs like Alliums, Frittilaria and Daffodils are not so delectable. Tamping down the soil after planting your bulbs makes it more difficult for critters to sniff them out. Laying some chicken wire over the area can also help deter from your bulbs becoming a meal for a critter.
Be sure to choose an area to plant your bulbs in that does not stay wet so the bulbs don’t rot.
Garlic
While some folks choose to plant garlic in the early spring, many people choose to plant it in the fall. Why not get started now? When you plant your garlic in autumn, you will have a crop that’s ready for harvest next summer.
Plant, Divide, and Transplant Perennials
Yes, you can still plant perennial flowers in the fall! Whether you’re purchasing new plants or moving plants around, autumn is a great time of year to do it.
It’s also a great time to divide and transplant spring and summer blooming perennials. Why divide your plants? It’s a great way to revitalize the plant and also to create new plants.
Whether you’re planting, dividing or transplanting perennials, it’s best to do it 4-6 weeks before the first hard frost so that they have time to become established in the soil. Perennial plants will be available for sale at Eising Greenhouses until Thanksgiving weekend, so don’t delay too much!
Trees and Shrubs
Container-grown or burlap-wrapped trees and shrubs can be planted as long as you can get a shovel in the ground! However, it’s a good idea to give them a few weeks in your garden before it freezes if you can.
It’s especially nice to see what a tree or shrub will look like in the fall before you plant it.
Peonies
Autumn is the best time to plant and establish roots so your peony is ready to bloom in spring! Planting them 4-6 weeks before the first hard frost will help your plant become established before cold weather descends.
👉 TIP: Be sure to add mulch to trees, shrubs and perennials after planting. But keep the mulch away from the trunks or stems. It’s never a good idea to put decaying plant material right up against a living plant!
Come in and take a look at what’s available, then enjoy the cool fall weather for planting!
