Add a lot of poo and compost. Dig out the area at least 1 foot deep, but 2 or 3 feet deep is best. We use an electric cement mixer to mix the poo (well-rotted farm animal), compost, and dirt (in equal parts; 1-1-1) and refill the area. We then use scaffolding boards to walk on so we don't compact the ground.
Tomato plants do best when they are planted deep. They will then grow roots from the stem/trunk.
Both lots of heat, so make sure you can provide that if you want to be successful.
Both are hungry feeders too. HOWEVER, do not use any product labeled "tomato fertilizer", unless it specifies early use. Use a general fertilizer for veg.
Once they start to flower, you then switch to "tomato fertilizer".
DO NOT water the plant itself as that will cause diseases and mildew. Water the ground and keep it evenly watered. Tomatoes will split if they get uneven watering.
If you are healthy or taking no meds, then you can give them pee once a week. You will need to dilute this to prevent burning the plant roots.
