Home: Protecting the Taxus Yew BonsaiWeevils are treatable. In May and July, you will need to treat the plant with lindane-based insecticides. The weevils will gnaw at the needles, bark, and shoots until they wither away and die. The tree will start to change color, usually yellow. Once the tree changes color, it will shrivel away and wilt until it dies. How to treat scale insects: The scale insects include the hard and soft shells. To treat the problem you will need to consider the bugs. The hard-shelled bugs are inactive species. The bugs often take possession of the fruit, leaves, and branches. You may spot the bugs by noting their dark brown or grayish brown shells. The bugs are small measuring around one-eight inch. The scale insects with soft shells will deposit waxy collections of shells, which appear around the branches, leaves, and trunk. Inside the shell is the soft shell scale insect, which secretes a sweet, sticky substance. (Honeydew) You want to eliminate this collection before it gets started, since honeydew will damage the blade of your leaves and breed "black fungus." The fungus is known as "sooty mould." If the tree is not treated, it will gradually die. You will notice discomposing signs when the needles start to change to yellow and fall from the tree. The branch will die, and the trunk will disfigure itself from its natural or shaped form. How to treat bonsai: To eliminate problems arising from the scale insects, use a sponged dipped in alcohol and water. Clean the leaves and stems. If the branches are infested, cut them and destroy the parts. During the winter, months you can rely on the birds to feast on the insects, yet in the spring you will need to use crude oils, such as the petroleum based to obliterate the scale insect. You can combine the oils with organophosphate insecticide to eliminate the problem. If the tree is fragile, you want to avoid over treating your plant. You can cause severe damage, or even fatality. Like cockroaches, the scale bugs are hard to eliminate. In view of the fact, you want to continue treatment as needed. If you have purchased your seeds, cuttings, or nurseries, likely you received directions for caring for your plant. Read the instructions and follow them as recommended. When treating plants with insecticides or related chemicals make sure you switch off now and again so that the pests do not become immune to the chemicals. Once the pests are immune, they will survive spray. Learn more about plant spray to choose Taxus Yew treatments.
