Garden Notes for May 2025.
The polyanthus plants have done very well this year. I even managed to win first prize with my entry in the Spring Show this year. May is a good month to divide primulas and polyanthus after they have flowered.
Remember that frost is still a threat, so be careful about planting out tender plants, especially in exposed areas of the garden. Better to wait until June. Sow biennials like Canterbury bells and Sweet William. Fast growing hardy annuals such as calendula, clarkia, cornflower, and nasturtium can also be sown, but do it early in the month.
For a quick tasty crop try sowing radish. The most common variety is ‘French Breakfast’ which is very reliable. For a change try Unwins’ ‘Rapid Red’, or Thompson & Morgan’s ‘Mirabeau’.
In unheated greenhouses or coldframes, now is the time to sow basil, calabrese, summer cauliflower, French and runner beans, kale, lettuces, parsley and sprouting broccoli. Put up supports for runner beans and late peas, but make sure that they will not shade out sun-loving neighbours. Remember to continue to earth up potatoes to protect them from frost and to encourage more tubers. It is also the way to stop the tubers from going green. If they become exposed to sunlight, that’s exactly what they will do.
Sow courgettes and marrow at a minimum temperature of 18ºC. Keep potting-on tomatoes as they outgrow their pots until they are in the final growing spot.
Direct sow beetroot, winter cabbage and maincrop carrots. Climbing beans make for a change. Some varieties that have been reported as doing well include ‘Isabel’, ‘Cobra’ and ‘Fasold’ often supplied by Johnsons Seeds and Mr. Fothergill.
If frost is forecast, protect the flowers of strawberries with fleece.
The Horticultural Society will be having their Plant Sale on Saturday 10th May in the Village Hall. This is an opportunity to replenish those plants that did not survive the winter. There will be vegetable and herb plants on sale.
Doors open at 10 a.m. and plants are sold on a ‘first come, first served’ basis. Supplies are limited so a prompt attendance is strongly recommended.
