Bell peppers should be fertilized prior to planting with an additional application following the first fruitset.
Bell Pepper Soil pH Requirements
To understand exactly what additional nutrients asparagus will require, you should always perform a soil test and base the fertilizing decisions on the results. Broccoli perform best in a soil with a pH of 6.5 to 6.8. They will not perform well if the soil pH is lower than 6.5 so you will need to raise or lower the Ph of the soil accordingly.
Fertilizing Bell Peppers
In the absence of a test, you can fertilize the soil prior to planting your peppers. Peppers perform well with a high phosphorous, high potash fertilizer. Work in two to three inches of compost then add a 10-20-20 fertilizer at a rate of two pounds per one-hundred square feet to the soil that is worked to a depth of six inches.
Peppers can be fertilized again after the first fruitset. Sprinkle a few tablespoons around each plant at least six inches from the base of the plant. Irrigate fertilizer into the soil.
Be careful not to feed plants too much nitrogen. Excessive nitrogen will result in lush plant growth at the expense of pepper production. Over fertilizing with nitrogen prior to fruitset will result in blossom and fruit drop.
