Pyracantha (firethorn) is a plant enjoying a huge surge in popularity.
This is easy to understand, as pyracanthas are some of the most versatile evergreens. They can be planted as an ornamental and vandal proof hedge or they can be trained to cover a garden wall or fence.
In late spring the branches are covered in a mass of small white flowers like the hawthorn blooms. In autumn the plant is covered with berries in vibrant colours like white, yellow, and red which will last until they are eaten by birds in December.
Pyracanthas will grow happily in most fertile, well drained soils in full sun or partial shade. Work in plenty of well rotted manure or garden compost into the soil before planting. One of the most popular ways of growing pyracanthas is to train them into a formal shape such as an espalier on a wall or fence. To cover a small area a trellis is suitable. For a large area use wires attached to a wall or fence posts. Leave a vertical gap of 18 inches between the wires so you can train the plant to any size you want. To train a newly planted pyracantha, tie its strongest branches to the wire on either side of the main stem and remove any small unwanted branches. In subsequent years continue to tie branches onto the support wire to extend the framework.
In June when the berries have set remove unwanted growth on the top and prune away unwanted growth so that the berries can be seen and enjoyed more easily.
Pyracantha are prone to scab which shows up as brown or greyish patches on the leaves and the berries often split and fall off. To control scab spray with a fungicide such as Nimrod-T in spring just as the new leaves are emerging, spray again when most of the flowers have fallen off and give the final spray a month after this. In recent years new disease resistant cultivars have been introduced which require no spraying.
There are other plants that will give you colourful displays of fruits and berries. Not only do they look attractive, but they are a great source of food for the birds in the coming months.
Cotoneasters are mainly grown for their clusters of small berries in reds and orange. Rosa rugosa is a dense vigorous rose which produces a succession of flowers in summer. These are followed in late summer by large coloured hips.
Sorbus (mountain ash) is a genus of about 100 species of deciduous trees and shrubs grown mainly for their white, yellow and red berries. They are ideal as a specimen tree in a small garden.
Skimmia is an evergreen shrub grown for their attractive glossy leaves, flowers and large red berries which last all the year round, birds do not eat them. To obtain berries a male and female plant must be planted in the garden.
Pernettya is a small evergreen shrub, 2-3 feet tall, that produces tiny flowers in June. In autumn and winter it produces bright marble sized berries in a range of colours such as white, red and purple. Plant in autumn or spring in moist well drained acid soil in sunny position. A male and female plant is required to produce berries.
Ugni molinae is a small evergreen shrub that used to be called myrtus ugni. It is a native of Chile and Argentina. It has dark green leaves and produces fragrant pink-tinged white flowers in summer. The flowers are followed by dark purple red berries in autumn. It is a frost tender plant that lives a moist, well-drained soil in full sun or partial shade with shelter from cold, drying winds. Give the plant alight pruning in spring to maintain its shape and size.
Jobs for the week
People have been asking what they can do with the colourful autumn leaves I mentioned last week. You can collect these fallen leaves and turn them into compost. Collect the leaves using a rake or garden vacuum. Place the leaves in a plastic bag with some holes punched on the sides of it. The leaves will break down over the next twelve months to produce valuable leaf mould which can be mixed with potting compost for your pot plants.
