How to Grow Pepper? A Detailed Guide to Planting Methods and Key Techniques

Pepper is a woody climbing vine native to Southeast Asia and now widely cultivated in tropical regions. How to grow pepper well?

1. Choose gentle slopes with good drainage, good sunlight and fertile sandy loam; the plantation area does not need to be too large, and windbreak forests should be established around it or native forest belts retained. The pepper garden should have a drainage system to remove standing water.

2. Deep plow the planting site to 30 cm, remove all debris; for slopes below 5°, build large terraces with a width of 6 m and plant two rows. For slopes above 5°, build small terraces and plant one row. Dig a small drainage ditch on the inner side of the terrace. On flat land, gentle slopes and large terraces, ridge planting can also be used. Planting holes should be 80 cm wide and 60 cm deep; when digging, keep topsoil and subsoil separate. After sun-drying for one month, backfill the soil, apply fully decomposed organic fertilizer and superphosphate, mix thoroughly with the topsoil and firm it down, forming a mound, ready for transplanting.

3. Pepper is mainly propagated by cuttings. Select cuttings from superior varieties for planting; choose vigorous main vines and remove the tips and prune branches 15 days before cutting the vine to promote fuller tissue. Cut cuttings 30-40 cm long with 5-7 nodes and branches on the upper two nodes, soak in water for half an hour, and place in a cool place to retain moisture. Insert them obliquely into the seedbed at a 40°-50° angle, leaving 2 nodes above the soil surface, and maintain 80%-90% shade and moisture. Rooting begins in about 7-10 days; after survival, gradually reduce shade and watering. After 20-25 days of cultivation, they are ready to be taken out of the nursery and transplanted.

4. Planting density and timing. Generally, spacing is 2×2.5 m. For fertile soil, 2×3 m can be used; for poor, thin soil, 2×2 m can be used. 5. Pepper needs support posts to climb during growth. When transplanting, dig holes 20 cm from the post, 30 cm deep, with a 50° slope on the surface, and compact them. When planting a single seedling, place the seedling facing the post; when planting double seedlings, place the seedlings facing the post in a “V” shape.

6. Water once 1-2 days after planting; after survival, watering can be gradually reduced. Within one year of transplanting, shade must be maintained; never let the sun damage the pepper base and cause seedling death. If any plants die after planting, replant them in time. When the pepper seedlings send out new vines, install support posts in time. In addition, pay attention to loosening the soil, weeding, fertilizing and tying the vines.

7. About 10-15 days after transplanting, reasonably apply nitrogen, phosphorus and potassium fertilizer as a top dressing, and carry out intertillage and weeding.

8. Generally, the shaping method of retaining 6-8 vines and pruning 4-5 times is used; 2-3 years after planting, the top is capped and production begins, giving a relatively high yield. When young and medium pepper plants send out new vines, excess buds and vines must be removed in time. When the canopy of fruiting pepper is too large and the branches are too dense, the old, weak and leggy branches at the top must be pruned away, and overly long outer branches shortened, maintaining balance between the upper and lower canopy, uniform size, and good ventilation and light penetration, so as to make full use of light energy and reduce disease occurrence.

9. Tying the vines of young and medium pepper plants in time can make the aerial roots well developed and firmly attached to the support post. When new vines grow 3-4 nodes, tie the vines once every 10-15 days. Use soft hemp fiber to tie several main vines evenly around the support post below the nodes, keeping each node of the main vine as close to the post as possible. In the direction of post replacement, the distance between main vines should be wider to facilitate later replacement of the support post. Fruiting pepper is tied 1-2 times per year, with a plastic rope tied every 50-60 cm.

10. Pepper can flower and fruit all year round. Young and medium pepper plants must have their flowers removed so the plants can grow normally. For two-year-old plants, when the crown width reaches more than 120 cm, the lower flower spikes can be retained to let them bear fruit, but fertilizer management must be strengthened to ensure normal plant growth. For fruiting pepper, in Hainan Province spring flowers are generally retained; in areas with lower humidity, spring and summer flowers are generally retained. Flower spikes produced in other seasons should all be removed.

Growing pepper requires a certain amount of care and patience. Pepper is afraid of standing water, so drainage measures must be well done in the garden.
