    Create an Allergy-Free Oasis: How to Landscape for Ragweed Season

    As we are well within late summer and the dreaded hayfever season is upon us, many find themselves battling the sniffles, sneezes, and itchy eyes of seasonal allergies, like me. While you can’t control the pollen count in the broader environment, you can significantly reduce your exposure and create a more comfortable sanctuary within your own backyard through strategic landscaping.

    The primary culprit of late summer and fall allergies is ragweed, a common weed that loves disturbed and forgotten areas. This evil plant releases vast quantities of extra-fine, lightweight pollen that can travel for hundreds of miles on the wind. Ragweed, being a wind-pollinated plant, requires the wind to spread its pollen from the male to female plants.

    On the other hand, many people mistakenly attribute their fall allergies to the beautiful and showy Goldenrod. Goldenrod’s pollen is heavy and sticky because it is insect-pollinated, requiring the showy flower to attract insects.

    Identifying and Eliminating Ragweed

    Before you can tackle ragweed, you need to know what it looks like. Common ragweed has fern-like leaves and produces small, inconspicuous greenish-yellow flowers on spikes, like the plant shown in the photo. It thrives in disturbed soil and is typically found in bare patches of your lawn or garden, as well as along the edges of gravel driveways and roads.

    The most effective way to reduce its impact is to remove it before it has a chance to release its pollen. Hand-pulling is a good option, especially after a rain when the soil is soft.

    Tips for Allergy-Conscious Landscaping:

    Beyond ragweed removal, a well-planned and maintained landscape can help reduce your exposure to these airborne allergens. Consider the following strategies:

    Mindful Maintenance:

    How you care for your yard can make a big difference. Keeping your lawn mowed to a height of about 5 cm or two inches helps to prevent grasses from flowering and releasing pollen. It also helps to ensure the weeds, like ragweed, are crowded out by the grass. It’s also best to tackle yard work on days with lower pollen counts, typically after a rain or in the evening.

    This is what you want to avoid! A poorly maintained lawn full of blooming ragweed. By keeping the grass maintained at 5cm or 2 inches helps to avoids this.

    Strategic Use of Hardscaping:

    Replacing some of your lawn with patios, walkways, or decks can reduce the area where pollen-producing vegetation can grow in your yard. These surfaces are also easy to clean, preventing pollen from accumulating. However, be cautious not to have too many hard surfaces, as this can lead to excessive stormwater runoff (a different concern).

    Create a Windbreak:

    Planting a dense hedge of low-allergen trees or shrubs can create a natural barrier that helps filter out windblown pollen from neighbouring areas. Choose varieties that are not significant pollen producers themselves, such as cherry trees, dogwoods, or hawthorns. With this type of hedge, you will also be supporting many pollinating insects, such as butterflies.

    Choosing Low-Allergen Plants for Southern Ontario

    The cornerstone of an allergy-friendly garden is selecting plants that produce little to no airborne pollen. Typically, plants with large, showy flowers are insect-pollinated and are safer to use in your plan. These showy flowers are designed to attract insects and usually have a heavier, stickier pollen, which can hitchhike to the next plant when the insect stops by each flower for a quick sip of tasty nectar.

    On the other hand, some trees and shrubs are dioecious, such as holly (Ilex spp.), meaning the male and female parts are on different plants. These dioecious plants typically use the wind to spread the pollen between them. If you are selecting a dioecious plant only because of its leaf characteristics, it is best to choose the female varieties, whenever possible, as they do not produce pollen.

    Some of My Favourites:

    • Serviceberry (Amelanchier spp.)
      • An early spring-flowering small tree or shrub that produces a tasty, edible, blueberry-sized fruit.
    • Hydrangea
      • This later-season flowering shrub has large, round flowers that dry and stay on the shrub over winter.
    • Wild Bergamot (Monarda fistulosa)
      • This perennial, with its pale purple flowers, is enjoyed by many pollinating insects, including many butterflies.

    Plants to Avoid

    Just as important as knowing what to plant is knowing what to avoid. Steer clear of plants that are known to be significant pollen and allergy producers, including:

    • High-Pollen Trees: Ash, Birch, Cedar, Elm, Oak, Pine
    • Grasses: Bermuda, Fescue, Timothy
    • Weeds: Besides ragweed, be on the lookout for other common allergenic weeds that typically have non-showy green flowers, like lamb’s quarters and nettles.

    By implementing these landscaping strategies and making thoughtful plant selections, you can create a beautiful and inviting outdoor space that serves as a welcome retreat during the height of ragweed season. A little planning can go a long way in reducing your allergy symptoms and allowing you to fully enjoy your yard.

    **TL;DR:**

    • Your late summer allergies are from the ugly green-flowered ragweed, not the beautiful yellow-flowered goldenrod.
    • Mow or pull ragweed out of your yard now before it releases pollen.
    • For long-term relief:
      • landscape with showy, insect-pollinated flowers (like Hydrangea),
      • plant dense hedges to block windblown pollen,
      • avoid high-pollen trees like cedars, oaks and birch.

  • Is Your Commercial Property’s Landscape Getting Destroyed in Winter??

    Is Your Commercial Property’s Landscape Getting Destroyed in Winter??

    Continuing on our theme from last week, winter can be a challenging time for the landscape of commercial properties. The harsh weather conditions, such as snow, ice, and de-icing chemicals, can take a toll on the aesthetics and functionality of the outdoor spaces. In this blog post, we will explore some solutions to help commercial property owners and managers maintain their landscapes during the winter season.

    1. Permeable Pavers

    One of the key issues during winter is the accumulation of snow and ice on walkways and driveways, which can lead to slippery surfaces and safety hazards. Using permeable pavers can help mitigate this problem. These pavers are designed to allow water and melting snow to seep through the surface, reducing the formation of ice and minimizing the need for de-icing chemicals.

    2. Snow Storage Areas

    Another challenge faced by commercial properties in winter is finding adequate space to store the accumulated snow. Creating designated snow storage areas can help prevent snow from piling up in unwanted areas, such as parking lots or walkways. These areas should be strategically located to minimize the impact on the overall landscape design.

    3. Heated Drives and Snow Melting Areas

    To ensure safe and accessible pathways for employees, customers, and visitors, consider installing heated drives and snow-melting areas. These systems use radiant heat to melt snow and ice, eliminating the need for manual snow removal or the use of de-icing chemicals. Heated driveways and walkways can also help prevent slip and fall accidents.

    4. Snow-Friendly Planting Design

    When it comes to landscaping in winter, it’s essential to choose plants that can withstand the harsh conditions. Opt for plants that are native to the region and are known to be resilient in cold climates. These plants are more likely to survive the winter and bounce back in the spring, reducing the need for replanting or extensive maintenance.

    In conclusion, winter can pose various challenges to the landscape of commercial properties. However, property owners and managers can maintain functional and visually appealing landscapes throughout the winter by implementing the right solutions, such as permeable pavers, designated snow storage areas, heated drives, snow melting systems, and snow-friendly planting design. Remember to choose plants that are native to the region and suitable for the specific needs of the property to ensure long-term success. By taking proactive measures, commercial property owners can create a safe and inviting environment for employees, customers, and visitors, even during the harshest winter conditions.
