In late June and early July we will be witnessing the annual invasion of the Japanese Beetle on many of our favourite landscape plantings including Hollyhocks, Dahlias, Hibiscus, Roses, Grapes, and Raspberries.

   Adult beetles skeletonize foliage.

   Many of us have tried the various means available to curb this yearly destruction like pheromone traps, Nematode lawn inoculation, hand picking, and concoctive sprays. But still, we get substantive damage.

   Interestingly enough, some plants such as Geranium, Castor Bean, and the flowers of Bottlebrush Buckeye, will cause paralysis and death of these beetles when eaten.

Maybe it’s Time We Look at Whole New Approach

Why not slowly invest in a landscape makeover? One with Japanese Beetle resistant plants!

   Trees such as Red Maple, Red Oak, Hickory, and Redbud could replace the susceptible Japanese Maple, Norway Maple, Pin Oak, Linden, and Mountain Ash.

   Why not consider growing more Evergreens such as Holly, Yew, Boxwood, and Aborvitae instead of the prone Virginia Creeper, Apple and Plum family of trees, and Birches.

   You also may want to contemplate planting perennials such as Coral-Bells, Hostas, Pachysandra, Sedum and Foxglove as opposed to the Japanese Beetle standard menu fare of Evening Primrose, Hydrangea, Clematis, Potentilla, and Zinnia.

   Yes, we do have some preventative measures at our disposal to battle the Japanese Beetle (find how to use beneficial nematodes in our fall chore blog) but due to the nature of this pest, it will inevitably win the war. If we continue to grow the some 400+ preferred host plants in our landscape, providing an adequate food source for this invasive pest rather than replacing them with resistant species, surely this pest will make gardening a chore instead of the pleasure it should be.

We hope this article will aid in the prevention of Japanese Beetles in your garden space! For more information – and Japanese Beetle resistant plants – visit Eising Greenhouse and Garden Centre! 🪲

Tropical Hibiscus evokes all of the best descriptions imaginable when you see one. Showy, stunning, exotic, vibrant, impressive, large, lush, colourful and flamboyant flowers grace branches of dark, glossy, green leaves. It just seems unreal! This plant conjures up images of the tropics, but it will grow in a pot on your sunny patio or inside your home!

Tropical Paradise

If you’re looking to create your own tropical paradise, this surprisingly low-maintenance plant is a great addition. Its showy trumpet-shaped blooms make it a great focal plant and the wide variety of shapes and colours available is astounding!

Tropical Hibiscus flowers are rich in nectar, attracting hummingbirds, bees, butterflies and other beneficial pollinators to your garden.

Planting tropical Hibiscus in a pot makes it easier to move the plant to a sunny, warm location, which provides the conditions for it to thrive. Be sure to ease your plant outside by hardening it off though. If it’s been indoors or in a greenhouse, give it time to acclimate, or it will become scorched or worse, die. Hardening off is a simple process of slowly easing your plants into life outdoors.

Blooming Good

Tropical Hibiscus will bloom all summer long here in southern Ontario when provided with sun, warmth, ample water and nutrients. During the growing season, water the soil regularly to keep it evenly moist. While it loves full sun, the sun’s rays can be dehydrating. Hibiscus is a thirsty plant when it’s in bloom so don’t let the soil completely dry out. Of course, there’s a limit to how much water you use. Too much water will cause the roots to rot. The key word is “moist”  - not monsoon wet! Using mulch will help to retain moisture in the pot.

To provide your plant with proper nutrition, use a time-release fertilizer in May or a balanced, diluted water-soluble fertilizer like fish emulsion about once a week over the summer months.

Each blossom lasts one day. They are short-lived, but don’t worry - Tropical Hibiscus will produce a succession of flowers during the growing season with ample light, water, and fertilizer. Once a faded bloom wilts, remove it from the plant to make way for the next one.

Looking Ahead

If you’re planning to keep your Hibiscus over the winter, here are a few tips to help.

Before the first frost, inspect the plant thoroughly for any bug hitchhikers or pests like aphids or spider mites. Give the entire plant a thorough shower and then bring it indoors. If you’ve found that your plant needs constant watering and has outgrown its pot, this is a great time for repotting before it comes indoors. Find a pot that is only 1-2” bigger than the pot it’s currently in and transplant it with some fresh, tropical potting mix.

This is another big transition for your plant, and you may find it loses some leaves unless you slowly migrate it from outdoor to indoor conditions. Place your Tropical Hibiscus in a warm, sunny window. Don’t move it to a cold basement right away, even if that will ultimately be its winter home. Just as you hardened it off in the Spring, slowly move it to a cooler location for winter storage if you don’t have a sunny, warm location. Be sure though that it ends up in an area where it’s getting at least 3 hours of direct sun each day.

At this point, stop fertilizing your tropical Hibiscus and reduce the amount of water used. Allowing the soil to dry out between waterings while the plant is dormant and not blooming is okay.

Enough talk of winter! While the weather is warm, pop an umbrella into a fruity summer drink and enjoy your beautiful tropical Hibiscus oasis!

Shrubs that flower in summer and fall make gorgeous accent plants for the landscape. We're so accustomed to seeing trees and shrubs blossom during spring, so it's a real treat to have all that vibrant colour and texture to enjoy throughout the later months of our growing season in Southern Ontario. 

While many gardeners will insist that summer is too hot to plant shrubs, that simply isn't the case! It can still be done successfully if you follow the correct steps to prevent your plant from getting heat stress. If you wait until later in the evening on a cloudy day to transplant a shrub, then water it thoroughly after planting, it will have all night to adjust to its new habitat and will be hydrated—ready to soak up the summer sun the following morning. 

Want to enhance the design and layout of your yard with some large, flowering shrubs? These late-season bloomers will bring a burst of colour and energy to the landscape, creating a fantastic setting for summer entertaining, hangouts on the patio, and picture-perfect photo ops.  

Bluebeard

True blue is certainly the rarest colour to encounter in the plant world, so we can't help but get excited when we see flowering plants sporting this deep, cool hue. Our Beyond Midnight Bluebeard is totally on-trend—after all, Pantone named 'Classic Blue' as the 2020 Colour of the Year! 

Bluebeard is a gorgeous flowering shrub that blooms from late summer to early fall, and its dark, glossy green foliage catches the sunlight beautifully. Plant it in full sun for best results, and prune it yearly in early spring, right at the first sign of new growth. Make sure its soil is well-draining because this shrub does not take kindly to soggy earth or stagnant water hanging around its roots. 

Butterfly Bush

These pollinator-friendly shrubs have incredibly vivid flowers that attract butterflies, bees, and hummingbirds alike. Our Crown Jewels variety has some of the brightest purple petals we've ever seen, nestled in a mass of golden lime green foliage. Talk about a high-impact colour palette!

Butterfly bush is an incredibly hardy plant that's resistant to drought and tolerant of rocky soils. You'll have to water it regularly for the first few months after planting, but by year two, you'll be able to just leave it be, and the regular rainfall will be plenty enough to keep it hydrated.  

Hydrangea Macrophylla

There's something so dreamy and beautiful about the lush clusters of flowers boasted by the hydrangea macrophylla—there's a reason why they're so popular for wedding bouquets! With so many different varieties and colours to choose from, you're bound to find a variety that suits your fancy. 

We really love our Bloomstruck hydrangeas because their colour can shift from blue to pink, depending on the soil's pH levels. The blossoms last all summer long, but even after they fade, this shrub adds so much visual interest through the fall, because of its emerald green foliage transitions into a rich, warm burgundy colour.

Rose of Sharon

Rose of Sharon actually comes from the hibiscus family, and it grows in an upright form that can be trained into a tree shape. Like most hibiscus plants, Rose of Sharon's flowers are quite large and showy. Our Woodbridge variety has stunning blossoms in a rosy blush shade, with a ruby red centre. It loves the sun and can grow up to ten feet tall and six feet wide, so it makes an excellent option for privacy borders around the perimeter of your yard.

Smoke Tree

The smoke tree gets its name from it's wispy, fluffy blossoms that look like plumes of smoke. If you love rich purples and warm fall colour palettes, you'll go absolutely gaga over our Royal Purple smoke tree, which has reddish-purple blossoms and foliage to match! Once autumn rolls around, the leaves will actually turn a brighter cranberry red shade. 

Make sure you leave plenty of space around your smoke tree when planting because they can reach up to 15 feet high and 12 feet wide! Regular pruning should help keep it a manageable size if you don't want it to get too large. Once it's established, it will appreciate it if you occasionally give it a thorough watering, especially in summer, during hot, dry spells.
