Tomato Growing in the Caribbean
Hello all. I'm located in this small Caribbean Island called Saint Lucia and I'm just starting off a high tunnel under which I plan to grow Tomatoes. Firstly we don't have winter, fall, spring here - only hot sun and rain. Even when it rains it is hot, lol. We also are just beginning to get into composting and do not have potting mixes on the shelves at our stores. We basically use the soil that we have and add some manure (cow, pig, poultry etc) and our farmers have never seem to get a loose and well aerated soil like what I see in videos from other parts. We do produce Tomatoes but are highly inconsistent because of diseases and we make assumptions about soil fertility.
Can anyone offer ideas about how I can make the soil rich and ideal for growing tomatoes without compost, and the other soil amendments that are available in the USA and other more developed countries? I do have a compost bin that I made but it won't be ready until the next 3months. I am basically seeking some advice on the soil preparation to improve it almost immediately so I can get the seedlings going.
