I used to grow 6 tomato plants, green beans, peppers and cukes.
There are two growing seasons for that type of produce. Plant in September harvest December and plant February or March harvest May and June. The only think that does well in the heat is okra. I had two jalapeño plants that produced for 3 years. Just pruned them in the dormant time and they would produce peppers about 8 months a year. I used a container system called earth box. Worked well for me.
