Garden Expert Urges Homeowners to Assess Trees and Shrubs Now

As winter begins to fade, now is an opportune moment for homeowners to assess the health of their trees and shrubs, according to local garden expert from Chilliwack. This period is crucial for evaluating the size, quality, and overall condition of the greenery surrounding homes. Taking advantage of brief sunny spells amid the typical rainy weather allows for a thorough examination of these important landscape features.

Homeowners should ask themselves key questions during this evaluation. Are the tree branches clean, or do they show signs of moss or lichen? Are there signs of healthy new growth, or are there dead branches that need to be pruned? Additionally, trees that have outgrown their space may create excessive shade or become unstable in inclement weather. Addressing these issues promptly can prevent more significant problems in the future.

Essential Care Techniques for Trees and Shrubs

If the task appears daunting, professional landscapers and arborists are available to assist with decision-making and implementation. For smaller gardens, many beneficial practices can be undertaken by homeowners with minimal effort and the right tools. For instance, if deciduous trees exhibit moss or lichen, applying a mixture of lime sulphur and horticultural oil is advisable. This treatment should occur three times, spaced two to three weeks apart, starting in early January. The horticultural oil acts as an organic insect control agent, while lime sulphur serves as a mild fungicide, making them an effective combination for maintaining tree and shrub health.

When applying this mixture, utilizing a pressure sprayer can yield the best results. A fine mist should be used to coat the branches thoroughly until the solution begins to run off. Fruit trees and shrubs like deciduous azaleas and lilacs typically respond well to these applications. However, caution is required with certain species. For example, maple, viburnum, and nut trees should not be sprayed with this combination. Instead, peach trees and nectarines require a copper solution to prevent peach leaf curl fungus. Additionally, covering these trees with a polyethylene canopy can help keep their leaves clean.

It is important to avoid using dormant sprays in windy, rainy, or extremely cold conditions, but light frosts are acceptable. Completing the three applications during the dormant season is crucial. After the final treatment, noticeable improvements in tree cleanliness and health should be observed.

Pruning for Healthier Growth

In addition to preventative treatments, now is an excellent time for pruning. Training and pruning fruit trees and small fruit plants can significantly enhance fruit production during the current growing season. Most evergreens, excluding spruce, fir, and pine, can also be pruned at this time. Shade trees may benefit from pruning to maintain a compact shape and overall health.

However, caution should be exercised with flowering trees and shrubs. Many of these plants are currently preparing for a vibrant spring bloom, so it is advisable to wait until after they have flowered before pruning. This is particularly true for mophead or macrophylla hydrangeas, forsythias, flowering currants, and numerous other flowering plants.
