Summer has finally arrived with the long bright evenings and the soil warming up resulting in a complete transformation of the garden and suddenly demanding our attention. Don’t panic, the season is just beginning. Follow these tips to help your garden bloom and flourish in the months ahead.
The important tasks for the month are as follows:
Garden centres are fully stocked with a colourful range of summer bedding. Planting out can now take place. If the weather is very cold the plants should be acclimatised by putting them out for the day and back in for the night..
The month of May is a good time to visit your garden centre to see the range and choice of flowering plants particularly perennials. Planting now will give colour impact over many months.
Dahlia tubers and begonias can be safely planted. By the time they are up, their tender shoots should be free of frost.
Lift and divide overcrowded clumps of daffodils and other spring flowering bulbs. Always allow five weeks after blooms fade as they have to replenish resources.
Prune early flowering shrubs as soon as flowering is over to prevent them from becoming overgrown.
Protect roses against blackspot by spraying early with a fungicide such as RoseClear Ultra.
Weed growth is now exponential. Don`t forget to keep weeding.
May is sow time for many vegetables. Succession sow salad crops, peas, carrots, beetroot, turnips and leeks.
Continue to earth up your potatoes as they grow.
Make sure to protect carrots from carrot root fly by placing a 60cm high clear plastic barrier around crop or by covering with fleece.
Cabbage root fly lays eggs from end of April so protect all brassicas with a disc around the base of the plants.
Put support stakes and netting in place for peas, beans and tomato plants.
Now is the time to sow new lawns and eradicate all weeds in existing lawns with Resolva Lawn Weedkiller.
Note: May is the month of vigorous growth - but watch out for cold snaps as you plant and sow.
