September Trees, Shrubs, and Roses Care Guide

Pruning and Clipping

• Finish clipping hedges as soon as possible to ensure neatness for a longer time.
• Prune shrub roses and ramblers by removing some of the shoots that have flowered.
• The lower branches of garden trees can be pruned to allow light to reach plants underneath.

Watering and Fertilizing

• Water camellias in pots to ensure they stay hydrated.
• Roses that were pruned after flowering and given some rose fertilizer may display a new crop of late buds and flowers.

Planting and Replanting

• Make preparations for late autumn tree planting by controlling existing grass and weeds with a suitable herbicide.
• Evergreen shrubs can be moved in September if they need more space.
• Plant bare-root or rootballed trees, shrubs, and roses in good weather conditions.

Weed and Pest Control

• Control grass and weeds in areas designated for planting in the autumn.
• If bindweed is a problem in shrub areas, untangle stems and place them on the soil surface for spraying with a suitable herbicide, being careful not to spray the shrubs.

Tree and Shrub Support

• Check that young trees are securely tied to stakes before autumn gales and winter weather.
• Ensure tall shrubs that can be rocked by wind are properly supported.
