Gardening Tips for May | Summer Garden
Summer’s on it’s way! Gardening tips for May with herbaceous borders growing and planting out bedding begins
In the Greenhouse
- Water tomatoes and peppers every day and feed at regular intervals, with a high potash feed.
- Plant cucumbers at the end of May – to avoid cold/wet compost conditions which can kill the plants.
- Sow sweetcorn, French beans and runner beans; but only plant out after the danger of frost.
- Hanging baskets and containers can be made up now, but keep them in the greenhouse until weather conditions improve. Wind can do more damage than frost! The larger the basket, the better the end result. Always use a high quality all peat compost – such as the Levington M2 Professional.
Geraniums will give the best show in a sunny spot. Pendular begonias, petunias and fuchsias prefer shelter and some shade. The most reliable basket plant is the single continental balcony type of geranium, especially in a long hot summer.
In the Vegetable Garden
- Plant out those beans, sweetcorn and courgettes. A wigwam made up of 4 x 8ft canes is probably the best runner bean support to avoid wind damage.
- May is a good time to set out Brussels sprouts and leeks for harvesting in early Winter.
- Also, this is the best month for sowing main crop carrots, to protect them from carrot fly cover with fleece.
- Keep earthing up the potatoes, check the earlies, as this excellent Spring could give you a lifting before the end of May.
In the Flower Garden
- Pull out spring bedding plants that are now past their best. Then fork in a plant feed dressing of “Growmore” fertiliser before setting out the summer garden bedding plants.
- With the demise of “Bizzie Lizzie” due to the mildew problem, a good alternative for the shady border or container is the New Guinea type of Impatiens, which are free from the disease. For an outstanding summer bedding plant, do not forget the small flowered begonia semperflorens. It is very tough, needs no dead heading – also rabbits and deer do not eat them.
- Keep watering all plants until they are well established.
- Herbaceous perennial plants needs support and dead heading where necessary.
- Dahlias can be planted to fill in the gaps, giving flowers until late into the summer.
- Spring and early summer flowering shrubs should be pruned just as the flowers fade.
- Water your planted hanging baskets and plants in containers every day.
REMEMBER that rain does nothing for baskets and wind dries, just as much as the sun. Feed twice a week, to the manufacturers instructions.
- A useful tip when going away on holiday, is to stand baskets in buckets against a north facing wall. If your neighbour forgets to water for one of two days, you should still have live hanging baskets when you return from your time away.
