Home: Protecting the Bonsai from DiseaseSpots affect the leaves of trees. The spots start out white and change to brown, or gray with black hollow rings, which develop into lesions. The spots form as 3-sided plane polygons, or triangles. The foliage is also affected, which it can wither. Once the foliage withers granules will start to appear in the center of the foliage. How to treat: If you notice symptoms, such as the ones named you will need to get rid of any leaves that show disease and obliterate them. Once you destroy, the leaves use copper-based chemicals that kill fungi, such as fungicides. DO NOT water or mist the plants in direct sunbeams. Again, DO NOT add, too much moisture to the foliage. To rid your plant of chalky mildew you can treat the bonsai with synthetic or mineral fungicides. You will need to cut the branches, which are infested. Destroy any cuttings, or infested branches immediately. Use your sprays. Use sulphur in the spring to prevent mildew. Mildew is noted for its whitish, chalky mycelium. Mildew's main section of fungus has a loose networking structure of fragile hyphae or filaments that shape the fungus and consists of feeding, which replicates hyphae. Mildew will attack stems, buds, leaves, etc. Mildew will grow thick around the plant, which distorts the leaf blades. The leaves and blades will finally shrivel and finally the tree will wilt away. Tip: to slow mildew take-away its desired climate, such as warm and dry conditions. Mildew is yeast in short, and grows rapidly. Treating the problem straight away is the key to growing healthy bonsai. Bonsai are subject to rotting roots. When honey fungus develops the main parts of fungus will send a chain of loose networks along its fragile hyphae and form bodies of fungus. The fungus feeds and replicates hyphae, which starts the cycle of serious conditions. Fungus will attack sickly trees, especially those that have been pierced by insects or damaged during cutting. If you notice the roots turning brown or notice rhizomorphs (Black threads of fungus parts moving from host to host), you will need to treat your tree. You will notice the rhizomorphs or brown spots beneath the bark. If the shoots are restricted of growth, it is an indication that your plant needs help. If the roots are rotting, you will notice dropping leaves and/or needles as well. The tree will wither; as well, the branches will decompose. To treat and protect your bonsai, once you notice an indications of rotting spray your tree with fungicide. The disease honey fungus, or root rotting is deadly, yet you can try to save your tree by spraying it with the fungicide. Verticilliosis affects plants, since it is a disease that starts from spore-producing organisms. The fungus grows a single cell or a multi-cellular life form lacking chlorophyll and replicates via spores, which it lives by absorbing nutrients from macrobiotic matters. As you can see, the bonsai is robbed of its photosynthesis process, which is minimized, and finally eliminated. To treat the problem you will need to avoid using excessive "nitrogenous fertilizers. The damaged sections of your tree requires careful consideration, as well you will need to get rid of any weeds. Dead leaves should also be removed and destroyed. Use a mineral-based fungicide to spray the soil, neck, and trunk of your bonsai.
