Plum tree gum disease is highly damaging, and complete eradication is imperative
Plum tree gum disease is an important disease on the trunks and branches of plum trees. When it occurs severely, it often causes the trunks to dry up and die, greatly affecting tree vigor and yield. It mostly occurs in warm and rainy seasons, especially in the south. Control measures: 1. Strengthen cultivation management. Apply sufficient base fertilizer when planting plum trees, and after entering full production years, increase fertilizer application...

Take good care of management in early summer for plum trees, and only then can the plums be high-quality and high-yield
Although the plum is a fruit tree with good yielding ability and strong disease resistance, due to poor management in early summer, it often shows severe alternate bearing, small fruit, and quality that cannot be guaranteed. Plum trees in full fruit period are mainly borne on short fruit branches and bouquet-like fruit branches. At present, plum fruit is in the fruit expansion stage. In order to enlarge the fruit, ensure uniform fruit size...

What are the key points of post-harvest management techniques for plum trees
Gummosis is a common non-infectious disease of plum and other stone fruit trees, with an incidence rate as high as 76%-95%. Affected trees show yellowing leaves and weak branches, declining tree vigor, severe fruit drop, and may even die entirely. The bark at the affected area cracks and swells, exuding a soft, transparent gummy sap that oxidizes and congeals into a reddish-brown gelatinous substance. Caused by gummosis...

Detailed Explanation of Flower and Fruit Management Techniques for Plum Trees
Plum trees produce a large number of flowers, but their self-pollination fruit-setting rate is low. To achieve stable and high yields, flower and fruit management is an important part. Flower and fruit management is mainly reflected in pollination, flower and fruit thinning, and flower and fruit preservation. 1. Pollination The most suitable time for pollination is in the early full-bloom stage. For pollination, choose flowers that have been open for no more than 3 days. ...

What causes plum trees to drop their flowers and fruit?
Plum trees flower easily, but often they are covered in blossoms yet carry only half a tree's worth of fruit. Heavy flowering consumes a lot of nutrients, and fruit drop is serious. Plum trees generally have three peak periods of flower and fruit drop: the first flower drop begins after flowering is complete, and the main cause is incompletely developed floral organs that have lost the ability to be fertilized or were never fertilized. The second fruit drop...

The most cold-hardy fruit tree: plant 2 at White Dew and they'll take root and grow, giving you more than you can eat next year
The "fruit tree" that fears cold the least: plant 2 at the White Dew solar term and they'll take root and grow, giving you so much fruit next year your mouth will cramp. Today I'm introducing a very unusual fruit tree: the "Blue Sapphire" grape vine. It can bear fruit for 100 days, and its nutritional value is...

Two essential points you must know for pruning plum trees
1. Root characteristics The plum tree has a shallow root system, most of which consists of absorbing roots, mostly distributed within the 20-40 cm soil layer, and the spread of horizontal roots is usually 1.2 times larger than the canopy diameter. The specific distribution range depends greatly on the variety and environmental conditions; for example, in deep sandy soil, vertical roots can reach more than 6 m. ...

Detailed Explanation of Key Management Techniques for Plum Trees During the Flowering and Fruiting Period
Management of plums during the flowering and fruiting period: Plum trees flower easily and have a high fruit-setting rate, but the fruit is small. To improve fruit quality, in addition to strengthening soil and fertilizer management and adopting summer pruning to control vegetative growth, flower and fruit thinning management should be carried out. Thin flowers during the flower bud swelling stage (late March), leaving one flower cluster branch and removing the next; at 20 to 30 days after flowering...

A Detailed Guide to Common Pests and Diseases of Plum Trees and Their Control Methods
After the first pinching of plum trees, pinch the new secondary shoots when they reach 20 cm, and pinch the developing branches when they reach 60-80 cm. If there are many branches, some can be thinned out; if the branches are not too dense, thin as little as possible and rely more on control. Before mid-July, clear all weeds from the orchard. 1. Bacterial shot hole disease, can use carbendazim...

Spring Pest and Disease Control Methods for Protected Plum Trees
1. Mound soil at the base of the trunk. Before overwintering adults emerge from the soil (mid to late May), build a 10 cm thick mound of soil around the tree basin and tamp it down firmly so that emerging adults cannot come out of the soil. 2. Apply pesticide to the ground. Before overwintering adults emerge (after petal fall), spray the tree basin with 75% phoxim emulsifiable concentrate at 0.5 kg/mu, or 40...
