A gardening expert has warned homeowners against planting five specific trees, citing issues such as invasive roots, aggressive growth, and toxicity. Edward Bowring, a plant specialist from Homes and Gardens, shared his advice based on personal experience managing gardens over his career.
Among the trees to avoid is the staghorn sumac, which, despite its attractive autumn colour, has a suckering habit that can overwhelm other plants and spread rapidly through seeds. Bowring also cautioned against planting laurel, noting that it grows quickly and can become too large, casting shade on neighbouring plants and requiring laborious hand-pruning.
The black walnut tree is another problematic choice, as it secretes juglone, a chemical harmful to many other plants. It also requires regular pruning, even in winter, and its falling fruit can be a nuisance. Weeping willows, while picturesque, need ample space to grow up to 50 feet and have extensive root systems that can damage underground pipes, making them unsuitable near homes.
Finally, the English oak, though strong and attractive to wildlife, demands plenty of room and regular pruning to prevent falling branches. Its roots can spread widely, damaging pavements and driveways, and autumn brings the chore of clearing acorns and leaves.
Bowring emphasised that aggressive roots, suckers, self-seeding, and toxicity are common issues he has encountered. He advises gardeners to carefully consider tree choices to avoid long-term problems in their gardens.
