Persistent heat, gusty winds and uneven rainfall have made it difficult for gardens and landscapes across much of Canada this summer.
As dry conditions continue, experts encourage homeowners to use water wisely by giving priority to plants that are most susceptible to drought stress.
Gardeners should ocus their irrigation efforts on plants that need consistent moisture to remain healthy during extended periods of hot weather.
Vegetable gardens are among the highest priorities. Crops such as sweet corn, beans, tomatoes and peppers depend on a reliable water supply during flowering and fruit development. A lack of moisture at these critical growth stages can affect both the quantity and quality of the harvest.
Applying a layer of mulch around vegetables, flowers and ornamental plants helps conserve soil moisture and reduces the need for frequent watering.
Gardeners are also encouraged to water early in the morning, giving plants time to absorb moisture before temperatures rise. Keeping tomato foliage as dry as possible can further help reduce the likelihood of disease.
Water needs vary across flower beds, ornamental plantings and groundcovers, depending on the species and site conditions. Areas that repeatedly struggle during periods of heat may be better suited to drought- and heat-tolerant plants in future growing seasons.
Container plants and hanging baskets require the most frequent attention because their soil dries out much faster than garden beds. Newly planted trees and shrubs also need regular watering to establish strong root systems.
Irrigation should thoroughly moisten the root zone without overwatering, particularly in heavy clay soils where excess moisture can harm roots.
Established trees and shrubs can also benefit from supplemental watering during lengthy dry spells, as many of their feeder roots remain close to the soil surface.
Although lawns may turn brown during hot weather, cool-season grasses often enter dormancy and usually recover once rainfall returns. A well-planned watering strategy can help maintain healthy landscapes through the remainder of the summer.
