The steps to growing peppers are very similar to that of growing tomatoes. When growing, be sure to only put them outside after all threat of frost has passed. Unfortunately, peppers are extremely sensitive to changes in weather. If the weather becomes too hot or too humid, the flowers may drop. Similarly, if the weather becomes too cold then the flowers may not blossom at all. Gardeners can't control Mother Nature so there is little to do about these situations but there are a few tips and tricks that can help with other issues that may arise when growing peppers.
When preparing the seeds for planting, dunk in a small amount of hydrogen peroxide using a strainer for up to one minute and then rinse. Do this just before planting time. It will remove any bacteria or other substances that may have inhibited the seeds germinating.
It has been suggested that peat moss, or soils containing too much peat, inhibit the growth and development of seeds. It is better to use soils rich in organic matter, mixed with a time-release fertilizer.
When first growing seedlings, it may be difficult to water them without disrupting their growing process. By placing a tray full of water below the container, it will allow the water to enter the soil from the bottom up. This will prevent seedlings from being disturbed unnecessarily. Remove once the top of soil feels damp to the touch.
Air circulation is also very important. Until the peppers have become established, they are susceptible to fungal growth. If you begin planting your peppers indoors before transplanting them outside, use a fan to circulate the air around the seedlings. This could ward off the development of diseases.
Finally, when transplanting peppers outside, be sure that the night temperatures have been staying consistently above 50 degrees. If they are exposed to temperatures below this, it could prevent them from growing.
