The Latest Daily Care and Management Key Points for Plum Trees
We all know that plums are the fruit borne by plum trees, and growing them requires a great deal of time spent on management. The main thing is to do a good job of daily care. The branches of plum trees grow very quickly, so pruning is a fairly important step for them. In addition, you also need to strengthen fertilizer and water management as well as other care. So let me explain it all in detail below!
1. Pruning Plum Trees
The key point in pruning plum trees lies in their short fruit branches, because flowering and fruiting are mainly borne on short fruit branches, so pruning of short fruit branches should be emphasized. In the first year, the focus is on shaping the tree form and controlling branch density to ensure the whole tree has a perfect shape. By the time it reaches the fruiting stage, you should focus on pruning the side branches and main trunk branches so that more short fruit branches grow, shortening the fruiting cycle. Also, overly dense branches should be pruned, and the branches and trunk should be pinched back in time to promote flower bud differentiation.
2. Fertilizer and Water Management
1. After the fruit is harvested and pruning is completed, the tree should be top-dressed. This is especially true because after fruit harvest, re-fruiting and the regrowth of branches both consume large amounts of nutrients. So we should dig trenches in the field, apply decomposed manure and elemental compound fertilizer in the trenches, and then water thoroughly.
2. Fertilization is mainly applied to the leaves, and then spreads through the leaves. Of course, environmental factors also play a large role. If the temperature is high and light intensity is too weak, the leaves will become very brittle. So fertilizing the leaves can make the leaves grow thicker and larger, with a stronger ability to absorb fertilizer, and their photosynthetic intensity will also be greater, producing more substances beneficial to the plant. In the early stage of the plum tree, mainly apply multi-element compound fertilizer with amino acids as the main element to supplement nutritional needs in many aspects. Spray once every week, and results can be seen after spraying for one month. When midsummer arrives, you can switch to a fertilizer mainly based on potassium dihydrogen phosphate for application.
3. At the end of summer, you should begin applying base fertilizer to prepare for autumn. For the base fertilizer, choose high-quality organic fertilizer as the main type, apply it generously all at once, and then water to dilute it. There is nothing special to pay attention to when it comes to watering. Plum trees also have relatively strong cold resistance, so basically just water normally, but you must prevent waterlogging. Sometimes heavy rainstorms occur, or too much water is accidentally applied, causing water accumulation. These are all things to watch out for.
4. Next is the method for preventing and controlling the pests and diseases that plum trees may have. After pruning and fruit harvest, plum trees should be sprayed once with insecticide and fungicide. Pest control is mainly aimed at mites, and mite-killing products such as "Mite Clear" can be used. For sterilization, carbendazim is enough. Everyone knows this. Also, bacterial perforation disease is a disease that tends to prevail in June, and some pests and diseases such as red spider mites, stinging moths, and brown rot should all be watched for. Once discovered, carbendazim, acaricides, and thiophanate-methyl powder can be used alternately, which can achieve a very high control effect. Early detection and early prevention and control should be achieved.
5. To promote flower bud differentiation, you can spray the plant with wettable paclobutrazol powder in June, and then spray according to the actual growth situation afterward to control the nutrients needed for growth. In late November, you can spray high-quality urea on the plum tree to force leaf drop. It takes effect after three or four days of spraying. Doing this can shorten the time for covering the shed.
The above are the key points for the daily care and management of plum trees. Have you all learned them? The daily care of plum trees includes the two major points of pruning and fertilizer and water management. There is nothing else. If you do these well, they will basically bear fruit smoothly. At the same time, pay more attention to pests and diseases, because their occurrence still has a great impact on growth.
