A tree in a bonsai pot can dry out surprisingly fast in the sun. Check the trees as often as possible and water them thoroughly whenever you water them. Spraying water onto the foliage late in the afternoon can help cool the foliage and container and reduce water loss. Reduce or suspend fertilization. If you are not seeing new growth in your trees,…

Indoor: If possible, these trees will benefit significantly from summer outdoors. Ideally, they should have all been moved out by now, but there is still time if you have not already moved them out—water as needed. Watering will depend on the weather, the location of the trees (sunny or shady), the soil, the pot size, and other factors. In many cases, however, daily watering will be needed. Always check the moisture content of the soil before watering. Fertilization should continue. Check wires for tightness. Repotting may be done at…
