Do not leave your Carmona bonsai tree outdoors on the cool winter nights, because they cannot tolerate the low temperatures.

Placing your Carmona bonsai tree outdoors during summer may help its growth. In cold temperatures, use a plant light to encourage growth. But also remember that these artificial lights can make the bonsai very dry. So, always take certain precautions or try misting your plant in dry conditions to keep it humid. If your Carmona bonsai is placed indoors at a windowsill, make sure that you close the window in the evening to avoid the frost air entering in, especially in winters.

2. Watering a Carmona bonsai tree

The Carmona bonsai tree needs moderate watering. It needs regular watering to survive but over-watering may cause root rot. Before you water the tree, check the surface of the soil. If it is a little dry, then water it, or else, wait for the soil to dry.

You can also use a moisture meter in the beginning to know your bonsai water requirements. While watering, slowly water your plant until the excess water comes out of the drainage holes. Water it twice or thrice a week in the spring, autumn, and winter seasons. But in summer, water your bonsai daily.

Carmona trees allow pruning as it can tolerate a little heavy pruning; you can prune the leaves and stem of your Carmona to get the desired shape and maintain it as a beautiful bonsai indoors. Pruning can be done throughout the year.

Although it can be pruned heavily, it is better to leave at least 2-3 leaves on a stem to allow its healthy new growth. Young stems and leaves can be trimmed easily but the matured stems cannot be pinched, so use sharp equipment for pruning and also to avoid crushing of stems. While trimming the roots, be careful because they are sensitive. If any part of your Carmona is infected due to some pests or diseases, then trim that part.

Wiring is a crucial part of designing your bonsai tree. Carmona plants may not need wiring but pruning is enough to be attractive. But if you still want to shape your carmona bonsai tree, use thin wires to wind the young stems of your bonsai while training, because they are flexible and can be easily shaped. Wind the wire loosely to avoid crushing it.

You can use the same type of wire to wind the strong branches and trunk; in this case, wind it a little tightly to get desired shapes. You can even use a thick wire to wind the trunk of your bonsai loosely. It is recommended to cut the wire, instead of rewinding it to prevent the cuts.
