When Do Longan Grapes Bear Fruit
The editor brings you an introduction to planting longan grapes and how long it takes for them to bear fruit, as well as experiences on why longan grapes may not bear fruit, with specific details as follows:
An Introduction to Planting Longan Grapes
Longan grapes are adaptable to the environment and are an ancient cultivated variety in China. They are widely planted from the Loess Plateau to Shandong, with extensive cultivation areas in Hebei, Shandong, Shanxi, and Shaanxi.
Longan grapes have a long lifespan, living about 150 years, and usually start bearing high-quality fruit after 7 years of planting. They enter senescence after 40 years, with yields gradually decreasing, and the fruit quality is best between 20-40 years.
How Long Does It Take for Longan Grapes to Bear Fruit
Longan grapes can bear fruit after 2-3 years of planting, usually blooming in May to June and bearing fruit after 90-100 days, which is around August to September.
Why Don't Longan Grapes Bear Fruit
Longan grapes may not bear fruit if they encounter frost damage or strong winds during the flowering period, which affects pollination. Additionally, poor nutrition and difficulty in flower bud differentiation can lead to pistil degeneration, resulting in no fruit. Lack of artificial pollination will also prevent fruiting.
Key Points for Planting Longan Grapes
1. Choosing a Planting Site: Longan grapes are adaptable and thrive in sunny, warm conditions. When selecting a planting site, prefer neutral sandy soil, and it's best to plant in loose, fertile, well-drained soil, whether on flat or sloping land.
2. Land Preparation: Longan grapes are usually cultivated using small trellises. We renew the soil in advance, dig planting trenches, and separate the topsoil and subsoil, apply sufficient base fertilizer, then fill with topsoil and water to settle.
3. Fertilization and Water Management: When planting longan grapes, apply sufficient base fertilizer. When the seedlings reach 20 cm, apply nitrogen fertilizer once, then apply urea every 15 days for 4 times, and apply potassium dihydrogen phosphate three times in August. In winter, apply high-quality organic fertilizer and water to prevent cold.
4. Disease Control: Longan grapes rarely suffer from pests and diseases, but in high humidity, high temperature, and poor ventilation environments, they can easily develop white rot and black spot diseases, which require spraying with pesticides. Commonly used pesticides include Kobo, Bordeaux mixture, carbendazim, thiram, metalaxyl, and others, used alternately.
