It is best to have new shoots on the top and cut the lower cut to about 60 degrees(7.48inch plastic plant pots). The substrate can be ventilated and drained sand. It must be disinfected before use. The thickness of the bottom is at least 20 cm.
Calcium absorption peaks twice a year: The first peak period is about 40 days after flowering, that is, the young fruit period(104 cell propagation trays wholesale). Spray 2 to 3 times of high-grade liquid calcium fertilizer, and combine it with the top water-soluble calcium when the first water is poured in spring(7.88inch plastic plant pots). The second calcium absorption peak period is about 40 days before fruit picking, and 2 to 3 days after bagging and removing the bag, calcium should also be sprayed 1 or 2 times.
(cheap 5 inch plastic flower pots wholesale uae)Calcium fertilizer application in autumn(50 cell seedling trays wholesale). This is a measure to solve various physiological diseases caused by calcium deficiency in apples. The other is to add calcium before harvest, mainly because the fruit body continues to expand, and the calcium concentration in the fruit decreases accordingly(polystyrene plug plant trays). Grasp fertilization during fertilization is very important, so let's find out more about it! To meet plum tree budding and flowering period, a lot of nutrition is needed.
When the base fertilizer is applied in the autumn after the fruit is dropped and before the leaves are fallen, the formula is used(128 cell plug trays supplier).

You can apply fast-acting nitrogen fertilizer about 10 days before plum tree budding(3.5inch square nursery pots). At this time, the young fruits and new shoots are entering the peak of growth at the same time. In order to avoid competing for fertilizers, timely application of fast-acting nitrogen, phosphorus, and potassium fertilizers should be applied in time to reduce physiological fruit drop(nursery containers for sale), improve fruit set rate, and promote the simultaneous growth of young fruits and new shoots.
