May Meeting | 'Dahlias' - Richard Ramsey | Tuesday 13th May, 8pm
The exceptionally dry March and April, culminating with the hottest day of the year so far on the 30th April (26.7°C / 80° F at Wisley) and an even hotter day forecast for the 1st May, it might be easy to think that summer is here. But it is still Spring and more seasonally normal temperatures will return. Make sure you keep an eye on night time lows, especially if you have young or tender plants outside.
When the sun is shining, it's worth taking time to enjoy your garden and perhaps relax with a copy of the latest May Newsletter!
Chop or crush the cloves from whole bulb of garlic and boil in a pint of water for 5 minutes and allow to cool
Strain carefully through muslin or kitchen paper suspended in a sieve, bottle, and store in the fridge
To use, dilute 1-2 tablespoons in a gallon of water in a watering can or sprayer
Repeat weekly
Protect tender new growth from frosts by covering with newspaper or horticultural fleece at night if possible.
Keep the greenhouse well ventilated and water regularly as warm days and rapidly growing plants will dry soil quickly.
In the vegetable garden, it’s time to direct-sow carrots, parsnips, radishes and beets, and begin to start succession sowing of salad crops for a continuous supply throughout the summer
Half-Hardy annuals and tender vegetables can be planted out gradually through the month, depending on how sheltered the planting area is. However, do not be in too much of a rush to plant half-hardy or tender plants.
All plants grown or started under cover or bought from a garden centre should be hardened off for a week or two before planting out. This process involves gradually acclimatising the plants to cooler outdoor conditions but protecting them overnight ensures they grow strongly when finally planted and are not shocked by the sudden transition.
Continue to mow lawns regularly. Bare patches can still be re-seeded, but remember to water frequently if the weather remains dry.
Moss and broadleaf weeds should be treated in early May, but most treatments require rain shortly after treatment
Leave the foliage of Spring bulbs to die down naturally – don’t be tempted to cut or tie. It’s a good idea to give them a water with a high potassium fertiliser such as a liquid tomato feed, as the treatment they receive now will determine the quality of the blooms next Spring.
Slug pellets containing Metaldehyde have now been banned for use. Try to use Garlic wash or other natural methods of control (including encouraging wildlife) to limit damage by slugs and snails.
Mid-May through to early June is ‘Chelsea Chop time’ where the stems of many late-flowering herbaceous perennials such as Achillea, Asters, Campanula, Echinacea, Helenium, perennial Helianthus, Hylotelephium (Sedum), Lavender, Monada, Nepeta, Penstemon, Phlox, and Rudbeckia are cut back by about one third to a half of their current length. Cutting all the stems on a plant delays flowering by 4-6 weeks and gives shorter, bushier plants. Cutting some of the stems of a single plant will extend the flowering period.

Rhododendrons are hardy, broad-leaved evergreens with spectacular springtime flowers. They prefer a cool, sheltered position with dappled sunlight and acidic, moisture-retentive soil, making them ideal under woodland canopies or along shaded borders.
