There are a couple of ways for approaching tomato growing in a greenhouse, you can either dig and prepare the soil of the greenhouse ready to accept the tomato plants or you can grow the plants in a container such as a plant pot (12″ diameter) or growbag.
Realistically most growbags that are available which can be 35 or 40 litres in size are only enough to support two plants. There are ways in which you can push this out to 3 plants but for the cost of a growbag its probably as well just to stick to 2 plants, particularly if you take good care of them and produce lots of fruit.
If you go for pots then you should steralise them before use, to do this you can use a dilute solution of a suitable disinfectant, something like Jeyes fluid is perfect for this task.
While we are on this subject, you really should wipe down the inside of your greenhouse with disinfectant as well to ensure any residual contaminants that could also cause disease are removed from the glass.
One of the reasons I am suggesting using large pots or growbags for growing tomato plants is because the soil in the greenhouse is going to need to be dug out and replaced every 2 or 3 years anyway to ensure that you get rid of any build up of disease and also because the soil will be pretty much spent in terms of nutrients.
Space is limited in a greenhouse so the best option for plant varieties is to use the indeterminate variety of tomato plant i.e. a vine plant. You can prune the plant to the required size, leaving about 4 to 6 trusses on the main stem, which is about 6′ to 7′ in height, greenhouse size allowing. This will give you lots of fruit over an extended period. You will have to pinch out the main stem when you have enough trusses to stop further growth.
As an aside, using the bush variety is less convenient for greenhouses because they, as the name suggests, form a determinant size of bush without pruning which is probably a little too large in diameter for the average greenhouse. The fruit also has a tendency to all come at once.
Irrespective of the growing method you choose, you should start to feed the tomatoes at the first sign of fruit and for the duration of the growing period, twice a week should be sufficient. Also as you are in a greenhouse regular and consistent watering is also very important and I recommend 2 to 3 times a day with water that has been allowed to warm in the greenhouse.
As the end of the season nears a way of helping the last remaining fruit ripen is to hang a couple of bananas in the apex of the greenhouse. If that fails to ripen the last bit of fruit you can always use the green tomatoes for making a delicious chutney.

Growing new plants from cuttings is a great way to increase your stock in a relatively short time. Rooted cuttings are often sturdier than seedlings, and come to maturity faster, many of them bearing flowers and fruits much earlier than seedlings.
Plants grown from cuttings are exact clones of the parent plant, so you know exactly what you’re growing, which is not the case with seed-grown plants.
When selecting a stem from the mother-plant, you should look for young, green growth. Young stems will always root better than more mature, woodier stems.
Cut just below a node (the joint where a leaf meets the stem) with a sharp pair of scissors. As an added precaution against contamination
You could also sterilize them with rubbing alcohol.
Plants send out new roots from nodes, so by exposing some of the node’s interior, you increase the chances of your new plant sending out a root from that node.
While the new plant need leaves to provide energy through photosynthesis, too many leaves will compete with the plant’s efforts to send out new roots. Leaving only 2-leaves is a good option.
Following plant cuttings give excellent results.
Take 10-inch long hardwood cuttings of pencil thickness in fall and plant out in the chosen location. Water the cuttings thoroughly until winter.
Take 4-inch long tip cuttings carrying 3-4 pairs of leaves. Remove the lowest pair and trim the stem closer to the node. Insert into moist rooting medium and cover with plastic sheet. You can trim the larger-leaves by 3/4th to reduce water-loss through evaporation.
6-8 inches long cuttings can be rooted, but it helps if the parent plant is allowed to wilt slightly prior to taking the cuttings. Withdraw water for a week and then take the cuttings 12-hours after watering the plant. The rehydrated stems take root more easily.
2-3 inch sections of the leaf can be used to make new plants. You can thus make a large number of plants from one parent plant. The only problem with this method of propagation is that the new plants will not carry the original variegation. Sections of rhizomes should be planted to retain the variegation.
All you need to grow these big-leaved beauties is a single leaf. Make a few slashes on the prominent veins on the underside of the leaf and lay it on a moist bed of peat-moss and sharp sand in equal proportions. Weight the leaf down with a few pebbles so that the cut edges remain in contact with the bed. Keep in a warm, well-lit place and watch the new plants appearing at these cut edges.
Some of the other popular plants that can be grown from cuttings include: lavender, Comfrey, Philodendrons, Holly, Fuchsia and many others.
Almost all herbs can be grown from cuttings and can be even grown in water.
