Which Trees Are Not Suitable for Planting in Orchards
The editor answers netizens' questions about which trees are not suitable for planting in orchards and presents a review of three types of plants that are not suitable for planting in orchards, including information on green plants and flower planting. Detailed content will be shared next.
Robinia
Firstly, Robinia is easily infested by stink bugs, which can harm peach, plum, pear, and apple trees. Stink bugs suck the sap from the tender branches, petioles, leaves, flowers, and fruits of fruit trees to sustain their lives. This can cause leaves to wither and fall, fruit to deform, and significantly impact the trees. Secondly, the tannic acid secreted by Robinia has a significant inhibitory effect on the growth of most fruit trees, especially pear and apple trees. It can lead to a substantial reduction in fruit yield or even no fruit production at all. Thirdly, the leaf blight fungus on Robinia can also infect pear, apple, and others, causing a large number of leaves to fall.
Paulownia
Because many fruit trees, whether seedlings, young trees, or mature trees, are prone to purple root rot disease. Once infected, the trees will experience yellowing leaves, drying, and even whole plant death. Paulownia, however, serves as an overwintering site for the purple root rot pathogen.
Cypress
Cypress and pear trees cannot coexist in the same area because the main disease affecting pear trees, pear rust,危害 pear tree shoots, petioles, leaves, fruit peduncles, and young fruits, leading to fruit branch atrophy, fruit deformation, rot, and fruit drop. Cypress trees, especially dragon cypress and juniper, serve as overwintering sites for the pear rust pathogen. When spring arrives and the weather warms up, the overwintering pathogens are blown back to the pear trees by the wind, continuing to propagate and harm them. Cypress trees also cannot coexist with grapes; when planted together, it is difficult for grape fruits to ripen, resulting in losses.
The above introduction about which trees are not suitable for planting in orchards and the review of three plants not suitable for planting in orchards should provide green plant enthusiasts with some knowledge of flowers.
