What to sow in January in the greenhouse?
The greenhouse has the advantage of allowing you to anticipate the return of sunny days by seeding some vegetables and flowers which you will then transplant into the ground when the weather and temperatures are milder.
The vegetables
To get a head start on your spring crops, from January onwards, you can do the following sowing:
- Carrots, radishes, onions, cauliflower, peas, leeks, cardoons : Be sure to install your bins or buckets close to the walls so that they benefit from maximum light,
- Lettuces in boxes.
- Summer vegetables : If your greenhouse has good insulation or you live in a region with a fairly mild climate, you can also start sowing summer vegetables, such as peppers and eggplants.
Flowers
For your ornamental garden or window boxes, you can also start seedlings of plants such as begonias, geraniums, lobelias, snapdragons and sweet peas.
Maintaining your greenhouse
In addition to carrying out your various sowings, in January, you must ensure proper maintenance of the greenhouse. To do this :
- Check your winter protection regularly.
- Be sure to clean the walls of the greenhouse regularly. Indeed, the days being short and generally less sunny, it is important to do what is necessary to allow light to enter better, because the plants need it.
- Whenever the weather permits, ventilate your greenhousein order to renew the air and allow plants and seedlings to benefit from purer air.
- Clean your tools regularly, containers, etc. in order to limit the spread of diseases which develop more easily in a greenhouse.
Care of overwintering plants in the greenhouse
If when the bad weather arrives, you have overwintered some of your plants in your greenhouse, there is no question of forgetting them. To take care of them:
- Monitor your plants regularly to quickly detect the first signs of disease or parasites on your plants. Be especially wary of whiteflies and mealybugs. If in doubt, do not hesitate to treat.
- Mist your plants regularly. This will prevent the atmosphere from being too dry, which red spiders particularly like.
- Prune fruit trees that you grow in pots and that you have brought into your greenhouse to protect them from frost.
- Be vigilant for the presence of rodents and other undesirables that may have found refuge in your greenhouse.
