I cleaned out the greenhouse today, moved my orchids, consolidated the seedlings to clear the way for the tomatoes! I grow my indeterminate tomatoes in fabric grow bags. Fabric grow bags are an excellent option as they allow for air pruning which is a process where the roots of the plant come in contact with the fabric inner wall of the pot they are forced to penetrate and grow into the breathable fabric. This causes the root tips to dehydrate and branch behind this point. I use 25 gallon Smart Pots and have been using the same ones for 5 years, they are a great investment and very economical in terms of a large pot. I think I mentioned this in a previous post but these pots, due to the size, support my tomatoes which reach 12 - 16 feet. I grow these tomatoes using a string which I have attached to a wire at the top. I merely twist the tomato around this string as it grows up and it essentially becomes self supporting. I will show some pictures of this as they get bigger. I grow 9 indeterminate tomatoes down the center of the greenhouse in roughly 2 staggered rows. I then grow a row right in the front of the greenhouse. This year I will grow 2 chilies, 3 cucumbers and 4 bush tomatoes. I have not bought tomato sauce, salsa or dried chilies in over 5 years - I will never see a return on my greenhouse investment but I am eating damn good stuff.
I have all of the plants on a timed irrigation system which I will be replacing this year (I will do a blog post on this) as I want to have the small bags and large bags on different watering cycles. This is really the best way to water tomatoes as over or under watering them is bad. You need to keep to a consistent watering schedule to avoid things like blossom end rot and too much water can leave your tomatoes having a watery taste.
