How many years does it take for Golden Finger Citron to bear fruit after planting?

Golden Finger Citron is a plant of the genus Citrus in the family Rutaceae, also known as “Finger Citron”, “Miluo Mandarin” and “Fushou Orange”, and is native to Southeast and South Asia. It is now widely cultivated in tropical and subtropical regions, and about 15 species have been introduced and cultivated in China. So, how many years does it take for Golden Finger Citron to bear fruit after planting?

1. How many years does Golden Finger Citron take to bear fruit

Golden Finger Citron will bear fruit 3 years after planting. Generally, the fruit set from March to May is called “spring fruit”, accounting for about 35% of the year's fruit. Spring fruit has a low fruit-setting rate, and the fruit is small and lacks visual appeal. The fruit set from June to mid-August is called “summer fruit”, accounting for 55% of the year's fruit. Protecting the summer flowers and summer fruit is an important step in improving the fruit-setting rate. The fruit set from flowers that bloom in mid-August is called “autumn fruit”, accounting for 10% of the year's fruit, and the fruit shape is poor.

2. Pest and disease control of Finger Citron

1. Sooty mold: After the plant is infected, small soot-colored spots first appear on the leaf surface, then gradually expand and turn black, covering the entire leaf and hindering photosynthesis.

Control method: Pay attention to drainage and pruning to allow ventilation and light penetration, and control scale insects in time. It can be controlled with 40% dimethoate emulsifiable concentrate at 1000 times dilution or 1:1:10 tobacco-lime water.

2. Anthracnose: It damages leaves, branches, flowers and fruits, causing leaf blight, flower drop and fruit rot. Use 25% Junwei emulsifiable concentrate at 1000-1500 times dilution or 800 times dilution of anthracnose thiram for control.

3. Leaf miners, citrus swallowtail and Chinese windmill swallowtail: The larvae damage the leaves.

Control method: Use 90% crystalline trichlorfon at 1000 times dilution for control. For leaf miners, use 0.6% Miechongling at 2000 times dilution and 20% Kangfuduo (imidacloprid) at 2000-4000 times dilution for control.

4. Scale insects and cottony cushion scale: They damage young branches and leaves.

Control method: Protect the natural enemy ladybugs; when they first appear, prune off the infested branches and destroy them; use 40% dimethoate emulsifiable concentrate at 1000 times dilution or 25% parathion emulsifiable concentrate at 1000 times dilution for control; use resin soap, with 8-10 times water dilution in spring and 16-20 times water dilution in summer and autumn, spraying once every 15 days for 2-3 consecutive times. For scale insects, use imidacloprid at 2000 times dilution or Supracide at 1000 times dilution for control.

5. Red spiders and aphids: They damage young branches and leaves.

Control method: Use pyridaben (Saomanjing) at 3000-4000 times dilution, azocyclotin (Kemanxi) at 1000-1500 times dilution, and propargite at 2500 times dilution for control. When pests and diseases occur, use these or other low-toxicity, low-residue pesticides for timely control. When applying pesticides, pay attention to the concentration used to prevent pesticide damage.

6. Old wood borers and brown spot disease: They bore into and dry out tree trunks. In early winter each year, use lime-sulfur mixture to whitewash the main trunk of the Finger Citron tree.
