May is the month hopeful of warm sunny days and blossoming gardens bursting with colour. Preparation for summer is well under way.
Jobs to be done:
Lily bulbs should be removed from the garden and placed into tubs.
Summer bedding plants can be put out into frames.
Multiple shoots on roses should be stopped and disbudding should begin.
Special attention must be paid to new lawns and regular mowing is essential. On existing lawns, use weedkiller on weeds that have taken hold.
Hedges may at this time need trimming, and newly planted hedges do need adequate watering during warm spells.
Once spring bedding plants have gone over, these should be removed as soon as they have finished blooming to make space for summer flowering plants.
Biennials and perennials for next year's flower display require sowing.
Caring for your garden can produce wonderful results and a great sense of achievement. These seasonal tips should help save time and prevent your hard work going to waste!
- In the greenhouse, humidity can be maintained by damping down plants. There should also be adequate shade to protect the plants from too much direct sunlight.
- Tulips once finished should be removed and bulbs should be allowed to ripen.
- Climbing plants such as clematis and honeysuckle need good strong supports, so check that these are adequate.
- Lawns, both new and established, need plenty of water during the coming months. A good soaking every 3 days or so will be fine.
- Herbaceous plants require staking, and delphiniums and phlox would benefit from a diluted liquid manure applied once a week.
