You can cultivate vegetables in the dead of wintertime making use of greenhouse vegetable gardening methods. To cultivate vegetables in a greenhouse is just about identical to raising them outdoors during the summertime. There are just a few additional things you will need to do to mimic what nature would do naturally.

To grow vegetables in a portable greenhouse you can use two methods. The first uses the sun’s energy during the day to heat up the structure and is called the cold method. When the temperature drops, a heating element will turn on to keep the temperature to a minimum of 45 degrees F. In this method plants don’t grow; instead they’re only maintained until they can be placed back outside in the summer.

Raising vegetables throughout the winter requires warmth so the warm technique is the one to use here. Garden greenhouses will need to maintain a temperature of at least 55 degrees F in order for the plants to grow and call for a heating unit. Heating devices can be gas, electric or propane.

There is scarcely a vegetable that can be grown in a garden that can’t be grown in a greenhouse. Look in seed catalogs to find seeds explicitly developed for greenhouse use. If you can’t find those get plants that maintain a compact size or that can be trimmed back to be smaller than the outdoor plants. There is little room in a greenhouse and you do not want it to be taken up with just a couple of kinds of vegetables.

Pollination is one of those things that you will have to do for your plants. Pollinating insects don’t exist in greenhouse culture most of the time so you have to do it for them. Pollinating a vegetable isn’t difficult. Tomatoes, for instance, ought to be tied to bamboo stakes and the stakes can be jiggled in the morning and once in the evening so as to pollinate. You’ll need to watch the flowers carefully to find out when you have to do this. When the flower opens and the petals all bend backwards it is time. You’ll only have three days to pollinate the tomatoes so take a look on a daily basis.

You will need to supplement sunlight throughout the wintertime too so plan on supplying grow lights in a winter greenhouse. Plants generally need 8 hours of sunlight per day. You will also have to supply water and fertilizer on a regular basis.

Greenhouse vegetables during the wintertime can be challenging to work with, more so than in the summertime, but it can be very rewarding. Tomatoes can be picked out of the greenhouse in the middle of winter. You will be able to have fresh vegetables any time of year.
