Spray the plant with Epsom salts (1 teaspoon dissolved in a spray bottle of warm water (about 4 cups). That gives the pepper plant a boost of magnesium that is required at flowering time to produce fruit. Spray them again 10 days later and in a few weeks, our expert friends report, you will have more peppers than you can eat.
plant top of pineapple in pot. I did this about 5 months ago and thought it didn't work, but I went to through away the what I thought was dead pineapple plant and it is very much alive and healthy. This actually worked so far.
SECRET Fertilizer :) My fertilizing cocktail consists of mixing 1/2 bottle of cheap beer, 1 tablespoon of Epson salts, and 2 tablespoons of fish emulsion in a watering can (1-2 gallons). I do this to ALL my vegetable, flowers, and indoor plants. You will definitely notice the difference in a few weeks! Dont waste too much money on the beer. Cheapest still works great -- plants arent picky!
