As the nights draw in and temperatures drop there is still plenty to do in the greenhouse. Sow sweet peas in a cool greenhouse for an early display next year. For more details, see October’s diary. Continue to sow batches of winter salads weekly in an unheated greenhouse (See September diary). As temperatures are lower […]
Sow sweet peas indoors from October to November. Soften the seed coat, by putting the seeds on a layer of kitchen towel on a dinner plate, put another layer on top. Dampen the towel, drain off excess water and sow as soon as they begin to swell or sprout, usually after about 48 hours. Those […]
When it is warm and sunny, sow trays, pots or old growing bags with ‘cut and come again crops’ to harvest through autumn and into winter, think land cress, oriental salads, like pak choi, mizuna and mibuna greens plus lettuce, lamb’s lettuce, chicory and radish. You can also use what’s left in the packets from […]
I’ve been having one or two problems with Blossom End Rot, where the end of tomatoes becomes circular, black and flattened. It occurs in peppers and aubergines, squashes and watermelons but is most often seen in tomatoes and is caused by lack of calcium in the fruits. Plants growing in soil, growing bags and potting […]
Now your greenhouse tomatoes are growing steadily, it is important to remove the side shoots of ‘cordon’ varieties to form a single productive stem. You don’t need scissors or secateurs, just snap them off with your finger and thumb. Make sure your tomatoes are well watered, too, particularly if they are in growing bags where […]
From now on my monthly tips are going to focus on what to do in the greenhouse, so let’s start with a few tips what to look for when buying a greenhouse. Buy the largest you can afford and leave space for expansion because however large your glasshouse, it will never be large enough! It […]
If you didn’t have time in the autumn, transplant conifers and evergreens later in the month, when soil temperatures rise. Dig round the plant just beyond the spread of its branches, cut carefully through any larger roots with a pair of old secateurs, keeping root damage to a minimum. Once the root ball is free, […]
Now it is getting chilly, terracotta or glazed pots should be wrapped with several layers of ‘bubble wrap’ or hessian and raised from the ground on bricks or pot feet to stop water-logging and reduce the chances of cracking. They can also be over-wintered in a frost-free glasshouse, at the base of a sheltered wall, […]
Start clearing leaves as soon as they begin to fall. Leave a thick layer on the lawn and the grass below soon dies through lack of light – it encourages turf diseases, too. Choose a still day if you can or rake or blow them in the direction of the prevailing wind. After collection, rot […]
Autumn is the season of lawn maintenance and this is what you do. Rake out the ‘thatch’ or dead grass and moss that has accumulated over the mowing season using a wire rake, powered lawn rake or scarifier that can be rented from the tool hire shop. To save money, you could hire one and […]
Before you go on holiday, it’s important to make arrangements for someone to look after your houseplants – ideally, someone who’s keen on gardening. If the draining board in your kitchen is not in shade, or you have a venetian blind to protect them from scorching sunshine (we live in hope!), group all your houseplants […]
Fresh tomatoes eaten straight from the plant, are one of the great pleasures of summer. So to get the best from your plants, keep them well shaded, ventilated, fed and watered throughout the growing season and ‘pinch out’ the stem just above the fourth truss to ensure that the fruits ripen. Feed with Epsom Salts […]
