A soil test may be necessary to determine the fertility of your soil. Excessive nitrogen fertilizer tends to force the plants to produce too much foliage and little fruit. Do not over-fertilize. Watering Peppers need about one to two inches of water each week. This varies according to temperature, type of soil, rainfall and whether or not a mulch is used.
Sandy soils require more frequent watering.
Heavy soakings at weekly intervals are better than many light soakings as light, frequent waterings promote shallow root systems. Mulching reduces water loss from the soil. Weed Control Weeds compete with pepper plants for sunlight, nutrients and water. In the average home garden, weeds are best controlled with cultivation or mulches. Mulches help keep weeds down, reduce water loss and stabilize soil temperatures.
