Plants to avoid in small gardens

“You need to be careful of any of the ficus varieties which have very vigorous root systems and like to go looking for water,” Cantwell says. “And if you’re going to plant anything that’s going to get to a decent height, you need to consider the structural elements, and ensure it all works together.”

If you’re landscaping a pool area, it’s important to understand the regulations that apply to swimming pools and planting, such as non-climbable zones. Bay trees (Laurus nobilis) are a popular choice for a poolside hedge. “They’re tough, thick, and can be used to create a beautiful evergreen narrow hedge beside a pool,” Ellis says. Plants with extensive root systems such as Chinese elms and rubber trees can cause enormous damage.
