Grapefruit is a fairly easy plant to grow, nor does it require you to have too high a pomelo planting technique, as long as you take good care of it, you can get a good harvest. You can refer to a few varieties of pomelos that are now widely grown by people such as Dien pomelo, green skin pomelo, five roi pomelo, stork feather pomelo, Phuc Trach pomelo, etc. Coming to today’s post, Agri .vn will guide you Grapefruit planting techniques as well as ways to care for maximum productivity.
Choose Grapefruit Varieties
Grapefruit can be divided into two main groups: extracted grapefruit and grafted grapefruit. You should choose grapefruit extract because grapefruit extract has a very fast fruiting time. The characteristics are easy to grow, easy to care for and the fruit is produced at a low level, the quality of the fruit is higher than that of extracted pomelo.
Along with that, grapefruit extract has the outstanding feature of a long lifespan. When choosing plant varieties, it is necessary to choose healthy plants, natural green pomelo leaves. The roots grow well, and there are no signs of pests.
And there is also a small note that you should only plant pomelos separately in another area, do not plant them with other citrus trees, such as oranges, tangerines, etc. Avoid cross-pollination, increase productivity of pomelo was reduced.
What month should I plant grapefruit?
The most ideal time to start planting pomelo is the end of the dry season and the beginning of the rainy season. That is from March to May of the solar calendar. After planting pomelos for a while, when they have new roots, they will receive cool rains to help the plant become healthier.
You will have to spend less time watering and the plants also have favorable conditions to grow. The suitable planting density of pomelo is 5m x 5m. Let the plant have enough space to grow, receive enough sunlight and absorb nutrients.
Soil preparation techniques for growing pomelos
Should choose planting locations with flat terrain, high drainage capacity to grow pomelos. The surface of the soil should be about 20 to 30cm higher than the surrounding water level 1. If not, you should open the trenches in the garden to increase the drainage capacity of the tree when it rains heavily.
The most effective pomelo planting technique
The technique of growing pomelo is not too difficult, you just need to apply the following procedures to completely complete the step of growing pomelo.
After you choose to buy a satisfactory grapefruit variety, remove the plastic covering the outside of the nursery. Do it gently to avoid affecting the roots.
Proceed to dig a hole slightly larger than the nursery pot, in the center of the hole prepared last month. Then place the pomelo tree in the hole, fill it with soil and press around the base with your foot until the tree is stable.
To prevent the tree from falling due to storms, or external factors that uproot the tree, you need to stick a fixed stake around and tie the tree in.
After planting grapefruit, you need to water the soil around the root. Then use straw, straw or duckweed root to cover to retain moisture for the soil.
Every few days you check the moisture of the soil once, if the soil is dry, you should add water to the pomelo tree immediately. During the period of one month after implementing the pomelo planting technique, the soil around the base of the tree needs moisture for the plant to grow well.
Proper care of pomelo trees
Grapefruit needs more watering when they are in the seedling stage, and in the flowering and fruiting stage. In the dry season, it is sunny and long, you need to regularly water to provide moisture for the plant.
The best time to water is in the morning (when the sun is not too hot) and in the afternoon. It is possible to use rice straw, or duckweed roots to enter the base of the tree to help limit water evaporation when the weather is too hot.
In the rainy season, to avoid flooding, you can open drainage ditches. Create ventilation, avoid letting the stump be flooded for many days. Causes root rot and leaf drop.
– Organic fertilizers
– Inorganic fertilizers: Trichoderma fertilizer to limit fungal diseases, especially diseases caused by the agent Phythophtora sp. cause.
– Tree period 1-3 years old: fertilizer is divided into several batches to fertilize pomelos. If phosphate fertilizer or DAP has been applied, use Urea fertilizer with a dosage of 10-20g dissolved in 10 liters of water to irrigate a pomelo root (1-2 months/time). When the tree is over 1 year old, apply fertilizer directly to the root.
– The period when pomelo trees have stable fruit: can be divided into 5 times as follows:
+ After harvest: apply 25% nitrogen + 25% phosphorus + 10-30 kg organic/root/year.
+ Four weeks before flowering: apply 25% nitrogen + 50% phosphorus + 25% potassium.
+ After fruiting: apply 25% nitrogen + 25% phosphorus + 25% potassium.
+ Fruit development stage: apply 25% nitrogen + 25% potassium.
+ One month before harvest: apply 25% potassium.
– Should add 0.5-1kg of Ca(NO3)2 fertilizer/plant/year in the post-harvest, before flowering and after fruiting periods. Foliar fertilizer can be sprayed no more than 3 times/fruit crop, at least 30 days apart each time. Do not spray foliar fertilizer in the rainy season because it makes plants susceptible to fungal diseases such as Ulcers, Pink Mold, Weed Spots.
– Fertilization method: Should be lightly plowed around the base according to the projection of the canopy, the width of the trench is about 30-40cm, put fertilizer in, fill with soil and water. Do not hoe too deeply as it can cause root breakage. It can also be combined with mud deposition, root cover to fertilize or use a harrow to scrape manure to help limit root breakage.
Pest control for grapefruit
During the implementation of pomelo planting techniques, it is difficult to avoid the situation of pests and diseases infecting the tree.
Grapefruit tree is a healthy growing tree and rarely suffers from pests and diseases. However, there are still some types of pests that sometimes appear on trees, such as:
Charming caterpillars: This is a type of pest that harms the tree when the new pomelo tree is young. They create wounds on the young pomelo leaves, the young shoots create conditions for microorganisms to access. Measures to kill and prevent: use Polytin 0.2% or slrespa 0.2%
Stem borer: To kill this disease you can use drugs: O fatox 0.1%, Symi sidin 0.2% to spray directly on the stem borer.
Anthracnose: You need to regularly visit and monitor the garden, when detecting plants infected with anthracnose can use drugs: Daconil 75WP, Mancozeb 80WP, Antracol 70WP.
To limit pests from forming on the tree, it is best to regularly clean the pomelo garden about once a month. Along with that is to whitewash the root and remove all damaged, infected branches.
Above is the information related to the technology of growing pomelo trees we want to share with farmers. Hopefully, through this information, farmers can deploy the best pomelo growing model for themselves.
