Water the rosemary bonsai when the soil feels dry. Use your finger to check the soil moisture. Water deeply until water runs out of the drainage holes. Ensure the pot has good drainage to prevent root rot. During summer, water more frequently. In winter, water less often. Always adjust watering based on the climate.
Yellowing leaves can indicate overwatering. Soft or mushy roots are also a sign. Check for a foul odor from the soil. The tree may show wilting despite wet soil. Reduce watering if these signs appear. Ensure the pot has proper drainage. Never let the bonsai sit in standing water.

Pruning And Shaping
Start by removing any dead or damaged branches. Use sharp scissors to avoid harming the plant. Cut branches at a 45-degree angle. This helps the plant heal quickly. Always cut above a leaf node. This encourages new growth. Remove no more than one-third of the plant at a time. Over-pruning can weaken the tree. Regular pruning keeps the bonsai healthy and beautiful.
Wire the branches to shape them. Use bonsai wire for best results. Wrap the wire around the branch gently. Bend the branch into the desired shape. Remove the wire after a few weeks. Avoid leaving the wire too long. It can cut into the bark. Shape the tree gradually over time. Patience is key in bonsai shaping.
Pest And Disease Management
Rosemary bonsai trees often attract common pests like aphids, spider mites, and whiteflies. Aphids are tiny insects that suck sap from the leaves. Spider mites cause yellow spots on leaves. Whiteflies can weaken the plant by feeding on the sap. To control these pests, use insecticidal soap or neem oil. Regularly inspect the tree for any signs of pests.
Rosemary bonsai trees can suffer from root rot and powdery mildew. Root rot occurs due to overwatering. Ensure the soil is well-drained to avoid this problem. Powdery mildew appears as a white, powdery substance on leaves. To prevent powdery mildew, ensure good air circulation and avoid overhead watering. Remove any affected leaves to stop the spread of disease.
