Growing Tips for Beginners: Greenhouse Gardening 101 The Romans were recorded as the first to create greenhouses, specifically growing cucumbers for Emperor Tiberius.

Damp, still air in the greenhouse causes grey mould, particularly on damp leaves or soft tissue like cyclamen flowers. It is less of a problem with good air circulation, so open greenhouse slightly vents on mild sunny days, shutting them before temperatures drop, early in the afternoon and avoid chilling draughts, (the lack of frost […]
It is time to sow sweet peas in a cool greenhouse for an early display next year. Soften the seed coat by putting the seeds between two layers of kitchen towel on an old plate. Dampen the towel, drain off excess water, sow those that start to swell or sprout after about 48 hours. Leave […]
Check your greenhouse heater early in the month to make sure that it works before the cold nights set in. If it doesn’t, there is still time to make some running repairs or to buy a replacement; it is worth having a cheap back up heater, on standby, too. Ventilate the greenhouse on sunny autumn […]
Sow Fennel, oriental vegetables like mizuna greens and Pak Choi, rocket, coriander dill, spinach, claytonia and land cress, in modules as soon as you can in August. These will germinate quickly and can be planted out by mid-August for cropping in Autumn. Continue sowing ‘cut and come again’ crops like mixed herbs, in pots, greenhouse […]

What a dreadfully wet winter we’re having. I hope that you aren’t suffering too much from the incessant rain from one of the wettest winter’s on record and your garden isn’t too waterlogged, either. Rather than letting the rainwater from the water butts on your greenhouse go to waste, water parts of your garden that […]
From early February onwards, it’s time to sprout (or ‘chit’) new potatoes. Put them in a tray or egg box with the ‘rose’ end, upwards (where all the buds or ‘eye’s’ are clustered), at about 7C (45F). After four to five weeks the shoots should be about 5cm (2”) long and they will be ready […]
Keep the greenhouse guttering clear of debris which reduces their effectiveness and can eventually block the down pipes. Clean all of your old pots and seed trays ready for sowing in spring. Wash with a solution of environmentally friendly disinfectant like Citrox, rinse, drain and allow to dry. Make sure you have pots and trays […]
