Any tree or shrub will suffer some degree of stress when uprooted. The shock of transplanting or moving can be lessened if the task is carried out correctly.
Tree rusts are fungal diseases causing dusty orange, brown or black spots (pustules) on the leaves of poplar, willow, birch and plum, and cankers on the stems and branches of five-needled pine.
It can be frustrating when trees and shrubs fail to establish well. The main symptoms of poor establishment are yellow or brown leaves and shoots dying back. There are steps you can take to remedy the situation, but it is better to try and prevent these problems happening in the first place.
Many trees, shrubs and woody climbers can send up suckers from their roots which, if left, will turn into another plant. Tree and shrub seedlings may also be a nuisance, as they are often numerous and can quickly spread, becoming deep-rooted.
Scab diseases of trees and shrubs can disfigure the plant by producing unsightly dark spots on the leaves. Blossoms and fruit can also be attacked and the vigour of the plant reduced as a result of premature defoliation.
When trees are felled or fall, their stumps should be removed to prevent suckering and fungal root rots. Although often large and heavy, stumps can be removed with the right equipment and technique, or removed by weedkiller.
Trilliums, also known as wake robin, are spring-flowering perennials with three petals sitting atop three leaves, much like a cup on a saucer. They are slow to establish but are then long lived. Like peonies they are best planted and left to establish over a number of years.
Tulip fire is a fungal disease of tulips caused by Botrytis tulipae, which produces brown spots and twisted, withered and distorted leaves. It is so named because plants appear scorched by fire.
Many viruses affect tulips, causing streaked flowers, mottled leaves, distorted plants and stunted growth.
Tulips are amongst the most popular of bulbs, valued for their brilliant flower colours and shapes. Plant in autumn for a show of spring flowers. Choose from a large range to suit the situation.
