Spring and early fall are generally the best times for planting trees. It has been found that newly planted trees thrive when exposed to moderate temperatures and rainfall, as they need time to root and acclimatize before the onset of intense heat and dryness of summer or the freezing temperatures of winter.
Now whilst planting different types of trees differ in detail, all trees eventually end up in a hole. But remember not just any old hole will do.
Let’s Get Digging!
1. Some trees are buried too deeply, causing the tree roots to decline in health and condition. We have a whole other article dedicated to transplanting depth if you wish to read more, but here’s the just of it: Poor tree health results in reduced growth rate, atypical leaf size and colour, increased disease susceptibility, and reduced cold hardiness. Always make sure that the root collar flare is visible after planting; if settling occurs, reset the tree to the proper depth.
👉 Note: Many times, homeowners build a raised bed garden around an existing tree in the yard (thus burying the root collar flare) only to find within a year or two their favourite tree now is in decline. Don’t bury that root collar flare!
2. As a general rule, trees should be transplanted no deeper than the soil in which they were originally grown. The width of the hole should be at least three times the diameter of the root ball or container or the spread of the roots in the case of bareroot trees. This will provide the tree with enough worked earth for its root structure to establish itself.
3. When digging in poorly drained clay soil, it is important to avoid 'glazing'. Glazing occurs when the sides and bottom of a hole become smoothed forming a barrier, through which water has difficulty passing. To break up the glaze, use a fork to work the bottom and drag the points along the sides of the completed hole. Also, raising the centre bottom of the hole slightly higher than the surrounding area. This allows water to disperse, reducing the possibility of water pooling in the planting zone.
4. The backfill soil should be a mixture of composted manure and topsoil. The mixture should then be placed in the hole surrounding the tree just to the height of the ball or slightly lower to allow for some settling. Be careful not to compress the backfill soil as this may prevent water from reaching the roots and the roots from expanding beyond the ball.
Jobs well done by the Eising landscaping team!
Standing On Its Own Roots
Young trees should be able to support their own weight when they are transplanted. If the tree is unable to do so, try thinning out the upper branches to reduce wind resistance. If that is not enough, you may have to stake a tree.
Watering Your New Tree
Newly planted trees should be watered at the time of planting. In addition, during the first growing season, they should be watered at least once a week in the absence of a good rain.
👉 Remember: Regular deep soakings are better than frequent light wettings.
We hope these tips can help you encourage the longevity of your new tree! For more information - and trees - visit our Trees & Shrubs section at Eising Greenhouse and Garden Centre. We hope to see you soon!
Dealing with water restrictions or choosing to conserve water? You’re not alone. Many gardeners in Norfolk County are facing the challenge of keeping gardens thriving with less water. The good news? A lush, colourful garden is still within reach—thanks to drought-tolerant perennials.
When we think of drought-tolerant plants, cacti might be the first thing that comes to mind. But there’s a surprising variety of beautiful, hardy perennials that can handle our region’s dry spells—no desert landscape required.
While these plants do need regular watering when first planted, once established, they’re low-maintenance and well-suited to Southern Ontario’s climate, including periods of limited rainfall.

A Little TLC
It doesn’t take much to keep drought-tolerant plants thriving—just a little attention and some seasonal TLC. While they’re tough, even these hardy perennials appreciate an occasional deep watering during extended dry spells, especially in their first year.
For sun-loving perennials, skip the heavy fertilizers. Instead, an annual layer of compost is all they need to stay healthy and strong.
Shade-loving drought-tolerant plants, on the other hand, benefit from a layer of mulch. This helps retain moisture and reduces evaporation, especially in dry shade, which is one of the most challenging conditions for any plant to thrive in.
And don’t forget to deadhead regularly! Removing spent blooms encourages your plants to keep producing flowers instead of going to seed, meaning more colour, for longer.
With a few simple care tips, your drought-tolerant garden can remain beautiful and resilient throughout the entire season.

Amaranth
If you're after drama, Amaranth is your plant! Reaching heights of 3 to 5 feet, these bold beauties flaunt long, rope-like clusters of maroon or red flowers. While low-maintenance, Amaranths may need a bit of support to stay upright as they mature.
Portulaca
Perfect for hot, dry, and neglected spots, Portulacas deliver a brilliant show of colour with minimal effort. Their rose-like blooms come in vivid shades of red, pink, yellow, white, orange, and purple. Low-growing at just 4 to 8 inches tall, they're ideal for the front of borders, or alongside driveways, and patios.
Salvia
With tall spikes of bold purple, red, blue, pink, or white blooms, Salvias are garden standouts. Growing 8 to 24 inches tall and often blooming continuously, they quickly become must-haves for flower beds or large containers.
Geranium
Drought-tolerant and tough as nails, Geraniums have long been a gardener’s favourite. Regular deadheading (removing spent blooms) will reward you with non-stop flowers until frost. Their lush foliage and bright flowers—ranging from salmon, white, purple, violet, and orange to red and pink—also shine in mixed containers. Geraniums typically grow between 8 and 24 inches tall.
Petunia
It’s no surprise Petunias have remained beloved for generations. They grow quickly, bloom prolifically, and require little care. Available in mounding or trailing forms—and sometimes carrying a heavenly scent—Petunias are perfect for flower beds, hanging baskets, pots, or window boxes. Growing 6 to 18 inches tall, they come in white, yellow, pink, purple, red, bi-colours, and even black!
Dahlia
Dahlias can become a full-on passion project—and it’s easy to see why. Their breathtaking blooms come in a stunning range of sizes, shapes, and colours. While Dahlias can be a bit particular (they love rich, well-drained soil and plenty of water, but hate soggy conditions), they are absolutely worth the extra attention.
Sunshine + Food + Hydration = Success
All of these annuals thrive in full sun and will reward you with even more blooms when given consistent water and fertilizer.
Adding a continuous-release fertilizer to your soil at planting time—or feeding weekly with a balanced, water-soluble fertilizer—makes it easy to keep your garden thriving all summer long!

During the dog days of summer, having a resilient, dependable, and beautiful perennial flower in your garden is terrific. Meet the Black-Eyed Susan. They are quick to establish and mature, and perfect for a perennial border, cutting garden, or naturalized garden. Depending on the variety, they will grow 1-3 feet tall and spread about 2 feet wide, making them a show-stopping spectacle!
If that and the cheerful, dark-centred, golden-yellow, daisy-shaped flowers aren’t enough to draw you in, here are more reasons we love these plants!
Long Blooming
Black-Eyed Susan (Latin name: Rudbeckia) is a prolific bloomer whose flowers can last from July to October. At a time in the season when many other flowers can look weary, Rudbeckia is a shining star. Its flowers grow on sturdy stems, which adds to their resilience.
Easy to Grow
Rudbeckia are robust! They are drought—and heat-tolerant and generally do well in hard-to-grow locations. Once established, they do not require frequent watering. Rudbeckia hirta is an Ontario native plant, and exceptionally hardy.
Plant Black-Eyed Susan in full sun to partial shade and almost any type of soil. They are adaptable, generally trouble-free and do not require any extra care.
Pollinator-friendly
We aren’t the only ones who love Rudbeckia; butterflies, birds and bees do, too. This makes Black-Eyed Susan a perfect partner for other pollinator-friendly plants like Monarda (aka Wild Bergamot and Bee Balm), Gaillardia (Blanket flower), Yarrow and Echinacea (aka Coneflower).
Who doesn’t love Black-Eyed Susans? Because of the course hairs on the stems, this is a plant that rabbits and deer don’t care for.
Black-Eyed Susan is perfect to grow in a border, bed, planter, or in a field as a mass planting. It’s resilient, attractive, low maintenance and a beneficial addition to any garden!
