It's the heat and humidity that usually does them in, plus lots of pests that they have little resistance to.
In Baguio they grow all the European stuff ok because of the cool mountain climate.
I had success (outdoors) with plum tomatoes...went crazy and I was harvesting tens of kilos, the local 'batchoy' ...good substitute for spinach, plus a few potatoes. Also sweet corn and garlic, Okra, green beans, sweet potatoes, Eggplant (Aubergines) Ginger, Lemon Grass, those little incredibly hot chillie Peppers, and we were lucky enough to have three massive Avocado trees and a Mango tree. I reckon we had half a ton of Avocados off those trees, which the Mrs. sold in our shop.
I also used to sprout trays of millet, but that was for the 500 or so aviary birds I had.
