You can cultivate vegetables in the middle of wintertime utilizing greenhouse vegetable gardening techniques. To raise vegetables in a greenhouse is practically the same as raising them outside throughout the summer. There are just several added things you must do to imitate what nature would do naturally.
You can use a portable greenhouse two different ways. One way is making use of the cold greenhouse system where the sun heats the greenhouse when it is shining. Night temperatures can go as low as 45 degrees F and beyond that a heating element will maintain that 45 degrees regardless of what the temperature is outdoors. Plants are merely maintained to be planted outside again in the summer making use of this system, however they don’t grow. Rosemary is a good example of a plant that will winter over in a cold greenhouse.
Greenhouse vegetables will need to have warmth and the second method, the warm greenhouse system, ought to be used if this is the case. This method will require more financial outlay because the temperature cannot fall below 55 degrees F. A heating system must be installed into your garden greenhouse. You can use a propane, electric or gas heater.
Most vegetables can be cultivated in a greenhouse. There are a few forms of each vegetable that are available in plants developed purposely for greenhouse growing. Look in seed catalogs to find those types. You want to look for kinds that will flourish in cooler temperatures than usual. You also want to find kinds that are more compact because room is at a minimum in a greenhouse.
Pollination is one of those things that you will have to do for your plants. Pollinating insects don’t exist in greenhouse culture in most cases so you have to do it for them. Pollinating a vegetable is not hard. Tomatoes, for instance, ought to be tied to bamboo stakes and the stakes can be jiggled in the morning and once in the evening in order to pollinate. You will need to watch the flowers carefully to discover when you have to do this. When the flower opens and the petals all bend backwards it’s time. You will only have three days to pollinate the tomatoes so take a look each day.
Because there is not a great deal of sunlight throughout the wintertime you need to add sunlight by using grow lights. Most vegetables need no less than eight hours of light a day. Of course, the plants will also have to be watered and fertilized on a regular basis.
Raising vegetables in a greenhouse in the winter might be a little more difficult and time consuming, however the results can be astounding. Just think of going out to the greenhouse mid January and picking a tomato right off the vine. You will have a little taste of summertime in the dead of wintertime.
