This article will introduce the cultivation methods and precautions of gardenia trees in detail. Gardenia trees are common ornamental plants, and they are loved by people because of their rich flowers and fragrant aromas. With the right cultivation methods and precautions, gardenia trees can grow lush, healthy and produce beautiful flowers.
First, the cultivation method of gardenia trees.
1.Choose the right environment: Gardenia trees prefer a sunny environment, the suitable temperature for growing is 20 -28, and it is necessary to choose moist soil and well-drained places for cultivation.
2.Propagation methods: Gardenia trees are propagated by seed and by cuttings. Seed propagation needs to pay attention to keeping the seeds moist and strengthening fertilization appropriately. For propagation by cuttings, it is necessary to choose a suitable time for cuttings and maintain the ventilation, temperature and humidity of the cuttings.
3.Soil management: Gardenia trees are suitable for growing in fertile sandy loam soils and are more demanding on the soil. Before cultivation, the soil should be loosened and fully tilled to facilitate the growth of the root system. At the same time, an appropriate amount of fertilization should be carried out according to the soil conditions to maintain the fertility of the soil.
4.Watering: Gardenia trees like to keep the soil moist but don't like standing water, so it's important to do the right amount and timing when watering. In general, you need to water 2-3 times in summer to keep the soil moist.
5.Reasonable pruning: The pruning of gardenia branches is an important part of maintaining the beautiful shape of gardenia trees and promoting the growth of flower buds. During the two periods of early spring, from March to April, and late autumn from September to October, proper pruning can be carried out to cut off poorly growing shoots and yellowed leaves.
2. Precautions for gardenia trees.
1.Pest control: Gardenia trees are susceptible to some common pests and diseases, such as aphids, reptiles, etc. Therefore, in the cultivation process, regular inspections should be carried out, and pests and diseases should be prevented and controlled in time, and appropriate chemical pesticides or biological pesticides can be selected for spraying.
2.Fertilization attention: In the cultivation process, it is necessary to pay attention to reasonable fertilization. Too much fertilizer is not good for the growth of gardenia trees and can easily cause root rot. Therefore, in the process of fertilization, it is necessary to grasp the dosage and frequency, and organic fertilizer can be selected for top dressing.
3.Pay attention to moisture: Gardenia trees have high requirements for moist soil, so care should be taken to keep the soil moist and avoid drought. The soil can be kept moist by covering it with a moisturizing film, watering it regularly, etc.
4.Proper temperature control: Gardenia trees are more adaptable to temperature, but extreme high or low temperatures are not good for the growth of gardenia trees. Gardenia trees need to be temperature controlled in a greenhouse or to maintain a suitable growing temperature.
5.Proper disease control: Gardenia trees are susceptible to some fungal and bacterial diseases, such as powdery mildew. It is necessary to pay attention to the rational selection of varieties with good disease resistance, timely detection of diseases to carry out disease treatment and source elimination, and choose appropriate pesticides for spraying.
