Pruning: Remove dead old branches and redundant branches from the plant, leaving only the main stem and one or two lateral branches. Leave four or five robust buds and remove twigs. Leaving three to five branches, one or two lateral branches and new buds from last year's main stem. When the plant blooms the first flower, remove all axillary buds under the first inflorescence, once the first pepper is established. This can ensure the yield and harvest time of pepper. Fertilization: if it is potted, you can change the foot fertilizer, decomposed chicken manure, pigeon manure, bone meal, fish meal, fermented cake (a small amount), plant ash and other mixed fertilizers; If it is planted in the field, the mixed fertilizer can be applied to one side of the plant. Pepper is an annual or limited perennial plant of Solanaceae. Annual plants are mostly large fruiting bodies with short growth period.

Pepper is usually planted in spring and can be harvested in about 3 months. When the temperature drops in winter, peppers will wither. Temperature is very important for the growth of pepper. Zanthoxylum bungeanum can grow in the "warm winter" weather in the south and in greenhouses all year round, such as Chaotian Zanthoxylum bungeanum, Millet Zanthoxylum bungeanum, Lantern Zanthoxylum bungeanum, Horn Zanthoxylum bungeanum, five-color Zanthoxylum bungeanum and so on, and some of them can grow into "Zanthoxylum bungeanum trees".

The cold outdoor peppers in the north can't survive the winter and can only grow once a year. Maybe pepper is once a year in the north, but it is the most common in our south. The stronger the drought resistance of Zanthoxylum bungeanum and Zanthoxylum bungeanum, the longer the time, the better, and some of them can last for 5-6 years, but their taste and feeling are a little different from those of new ones. The skins of these peppers have thickened. First of all, look at the growth of pepper. If it is good, cut off those dead branches. If there are many new branches. Cut less, so the sun won't shine, and peppers are easy to get sick, so the yield is less.

Generally speaking, fertilization in rural areas depends on the situation. If the branches of pepper trees are dark green, we don't fertilize them. If the pepper tree is a little dark yellow, we will collect some farm manure near its roots and cover it with soil, so that when it rains or waters, the pepper tree can eat the fertilizer.
