Apricot tree requires a lot of water but does not tolerate waterlogging, if it is flooded for many days, it is easy to rot its roots. When the tree has buds, if there is a shortage of water for a few days, then watering the tree again will lose its leaves and flowers bloom early, this is a factor to pay attention to to help flowers bloom on Tet holiday. How to take care of apricot tree: 1. Watering: In order for apricot trees to bloom in time for Tet, watering is a very important factor. Each locality, each region has a rainy season and a dry season that changes, and the irrigation water must also change accordingly. - Potted plants: watered twice a day in the dry season, once a day in the rainy season. - Land crops: in the dry season, watered 1 to 2 times a day, in the rainy season, it can be watered once every 1-2 days. It should be noted that in both cases when the rainy season is about to end, it must be heavily watered every day until December of the lunar calendar to gradually reduce the amount of water for irrigation: once every 2 days to prepare to pick apricot leaves. 2. Prevention of pests and diseases: Pests: - Stem borer is the type of worm that causes the most damage to trees, lack of observation, branches of apricot tree are easy to die or the whole tree dies .The best preventive measure is to broadcast Sargent 6G every 6 months. - Aphids: aphids of all kinds, such as flower hoppers, mealybugs... sucking sap causes leaves yellow twisted leaves and branches to die . It should be noted that aphids and aphids are also viral pathogens. If the population is small, Sairifos 585EC can be sprayed twice a week at the indicated dose. If aphids are too much, mix Sairifos 585EC + mineral oil SK 99EC sprayed twice a week, observe if the hoppers are dry or dead, stop. In addition, there are a number of insecticides for hoppers ,aphids, and thrips that are quite effective, such as Sapen alpha 5EC, Sec Saigon 25EC. - Other leaf-eating pests such as diamond back moth, sows... Spray insecticides such as Sherzol 205EC, SK Enspray 99EC... every 10 days. Diseases: - Pink fungal disease is quite dangerous for the tree, the fungus clings to the leaves, burns the leaves, and dries the branches. Saizole 5SC can be used to thoroughly wet the foliage 2 times, 5-7 days apart, when early disease appears. - For fungi that burn apricot leaves, it is recommended to use Mexyl MZ 72WP, Alpine 80WG sprayed according to the guided dose twice 5-7 days apart. - With symptoms of physiological diseases caused by micronutrient deficiency such as Bo, Mo, Fe, Mg, Mn... Foliar fertilizers such as Tano 601, Tano 606, Polyfeed 19-19-19 can be used to supplement nutrients for tree. 3.
