Practical Methods for Winter Pest Control and Disease Prevention in Bonsai
Cold winter is a very difficult season for pests in bonsai, so this season is also a good time for pest control and disease prevention. So how should you do a good job of pest control and disease prevention for your bonsai in winter?
Bonsai
1. Clean up the bonsai garden.After winter begins, thoroughly remove dead branches, fallen leaves, weeds, rotten fruit, and so on, scrape off overwintering pests such as scale insects and the raised bark, diseased bark, cracked bark, and disease spots on the branches and trunks of bonsai, and promptly burn them in a centralized manner to eliminate overwintering pests and diseases.
2. Whitewashing for pest control.After cleaning the bonsai garden in winter, brush the main trunk, large branches, and trunk of bonsai with a mixture of 10 parts water, 3 parts lime, 0.5 part lime sulfur concentrate, 0.5 part table salt, and a little oil or grease. This can kill overwintering pests and diseases on the trunk and branches.
3. Filling holes for pest control.When borer holes are found on the trunk or branches, inject 160-fold Bordeaux mixture with a syringe, then seal the holes with lime slurry. This can effectively eliminate the pests inside the holes.
4. Pruning for control.In combination with the winter shaping and pruning of bonsai, cut off dead branches, mummified fruit, dead buds, and debris such as hanging ropes left on the tree, carry out a thorough pruning (care should be taken to maintain a beautiful shape) and cleaning of the tree, and pile up and burn the various diseased and residual materials removed. In addition, the fruiting branches and branch groups of already aged fruit-viewing bonsai are also hiding places for overwintering pests, so they should be pruned and controlled in time, and rejuvenated while maintaining the beautiful posture of the bonsai.
5. Turning the soil and applying pesticide.In winter, evenly spread medicated soil (500 g of 50% phoxim emulsifiable concentrate mixed with 50 kg of fine soil) in the pot of the bonsai, then turn over the potting soil and work the medicated soil into it to kill pests overwintering in the potting soil.
