Pruning and Training
- Prune spring shrubs as they go out of flower, if necessary, to manage size and shape.
- Continue to tie in new shoots of climbing roses for proper positioning and safety.
- Prune early summer shrubs as they go out of flower, such as broom and weigela, for size reduction without changing the shape.
Disease and Pest Control
- Spray roses regularly against blackspot disease, especially in damp areas and after wet weather.
- Check Japanese maples for greenflies and chestnut scale on branches, using insecticide if needed to prevent dieback.
Watering and Weed Control
- Water young trees, hedging, and recently planted shrubs during dry spells to encourage rooting.
- Maintain a weed-free circle around young trees for about five years, using old carpet, plastic, or suitable weedkillers.
Staking and Clipping
- Check that recently planted trees and shrubs are securely staked, if necessary.
- Clip vigorous hedges such as privet, lonicera, and Cotoneaster lacteus.
By following these care tips for trees, shrubs, and roses in May and June, you can keep your plants healthy and attractive while managing their growth and protecting them from diseases and pests.
