I have a new jacaranda tree i just planted in a pot from a seedling and it did awesome in the summer Northern California heat but

Question

i just noticed the leaves are yellowing a little and are not as green. Is this because fall is here and winter is on the way or i s something else wrong. I do feed it plant food each month.

Answer 1

I would chalk this up to the plant food. What kind are you using? A tree will not use nutrients near as fast, and can be fed once or twice per year. Feeding once per month will lead to a nutrient build up, pH issues, and many other issues.

Depending on how cold it gets, they can die back partially, or fully. They can only survive down to 15F. It is very likely that the cold can affect it, but from the amount of food that it is receiving, I would say that it would be best to correct this first.

From here, I would start out with fresh soil, and fertilizers that are well balanced. A slow release will be best. If this is already in ground, then stop feeding at all over winter, and let that leach out of the ground until next season.
