So how do you grow it? Let's take a look at the planting techniques of gardenia together with Xiaobian.

1. Land selection and preparation

selecting alluvial soil or black soil with deep soil layer and loose and fertile soil as seedbed, wherein the seedbed is required to be convenient for irrigation and drainage, applying 2000-4000 kg of manure per mu as base fertilizer, deeply turning and burying the soil, and raking and leveling to make a high ridge of 40cm. Select a gentle slope or plain wasteland with sufficient water source, convenient irrigation and drainage, facing north and south as planting land, reclaim well before planting, open holes according to plant spacing of 1-1.5 meters, and apply decomposed farm manure 4kg as base fertilizer for each hole.

2. Breeding methods

Gardenia is mainly propagated and raised through seeds and cuttings during planting and production. Seed propagation can be carried out in spring or autumn. On the prepared seedbed, holes are opened according to the row spacing of 25cm. The treated seeds are scattered into the holes, covered with a layer of fine soil mixed with plant ash and phosphate fertilizer, covered with soil and covered with grass to avoid soil hardening. 2-3 kg per mu of seed month is used. Cutting propagation can be in February-April and September-October, select strong growth, 1-2 years old branches, cut them into 7-20cm cuttings, in the bed surface according to the row spacing of 15-30cm cuttings. Cuttings are cuttings to be slightly inclined, buried one-third, exposed a bud section can be inserted after frequent watering, keep the soil moist, a year later can be planted.

3. Planting

After one year of cultivation, seedlings can be transplanted when they grow to 25-30cm. If seedlings do not grow to this height, topdressing and weeding should be done in time, and planting should be done in autumn and winter of the same year. Planting time is generally in the first half of the spring to Qingming, the second half of the autumn and early winter, planting seedlings to bring some soil and phosphorus fertilizer, in the prepared planting ground, each hole planted a plant, fill compaction, irrigation enough water.

4. Field management

In the cause is to timely intertill weeding, mainly weeding, intertill to shallow tillage, not deep ploughing, in winter combined with garden cleaning and fertilization cultivation once, so that it can safely winter. After planting, topdressing is essential. In the vegetative growth period, topdressing should be mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, and some organic fertilizer can promote the formation and growth of crown. After entering the fruiting period, phosphorus and potassium should be given priority to increase the fruit setting rate and fruit number, and achieve the goal of high yield. Proper pruning during planting can also pass the yield of Gardenia. When the plant grows to 50cm, it should be pruned. The creeping branches, weak branches, drooping branches, retrograde branches and dead branches with diseases and insect pests should be pruned 30cm away from the trunk, leaving only one thick branch and 3-4 auxiliary branches in different directions, which can promote the formation of crown.
