If you missed sowing broad beans in autumn, sow some now under glass for an early summer harvest, 5-8cm apart and 2.5cm deep in deep trays of multipurpose compost or singly in small pots. Put them in a cool frost-free greenhouse, and harden them off before planting outdoors in early spring. Use the hardy varieties […]

The winter months, when apart from popping into the garden to enjoy the winter flowers and harvest vegetables are one time of year when you really appreciate the pleasures of having a greenhouse to potter in. It’s not the busiest period of the year but you can still weed the benches, continue to sow ‘Cut […]

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 […]

While temperatures remain high, watering and ventilation are top of the list. Open vents early in the morning, as temperatures in the greenhouse soon rise (shading should be in place by now), water preferably in the evening or early morning and check plants several times a day to ensure that they don’t dry out. Consider […]

Now’s the time of year to buy Amaryllis, (Hippeastrum) ready for flowering for the festive season. Start them into growth in the greenhouse then bring them indoors to flower. Water sparingly at first; trickling a little tepid water around the bulb, and increasing the amount as growth appears. Once they are actively growing, keep them […]
