Garden Notes for January 2021.
This is the time of year when houseplants are most appreciated. Azaleas, cineraria and cyclamen will all help to cheer things up. Do not over water, and most of these plants like cool conditions.
January is a good time to order gladioli corms from reputable suppliers. Sweet peas can be germinated under glass with some heat. Plan spring planting programme for flowers. Complete digging beds and borders to be used for annuals when the weather is suitable. Do not disturb soil when it is frosty.
When your seeds arrive from the supplier keep them in a cool dry place until required. Protect pea seeds in particular because mice love them, and they have already got into our garden shed where they have started on anything that they can reach. Remember paper is no barrier to sharp teeth, and makes lovely nesting material.
Rhubarb can be forced using an upturned bucket or tub. This should be covered with garden fleece to keep off any frost.
It is wise to get your seed potatoes now when there is a plentiful supply, but popular varieties soon get sold fast with the result that you end up with the less well known types. When the seed potatoes arrive, keep them in a frost-free place and stand the tubers, eye-end uppermost, in shallow boxes. If you can get large egg trays these are ideal for keeping the tubers upright and just separated to prevent any infection spreading.
You may want to think of biological pest control. There have been huge developments and you can get natural solutions to pests such as vine weevil and whitefly. In fact there are over 10 different pests and diseases that can be controlled in this way.
Start the first sowings of onion seeds this month. Also give a good dressing of wood ash on the site of the bed that you will use, since they really like potash. If the weather is suitable, shallots can be planted on well drained soil, or plant them individually in 3 inch pots.
