A friend planted a Jacaranda Tree in Sacramento in September last year. It lost its leaves in December and January and has not grown any new leaves since. Is this normal? When should the leaves and the floweres start to grow again? The tree appears to be still alive because it is still green under the tree bark. Is there anything that she can do to help it along at this time or is it still dormant? The temperature during the day is less than 75 degrees but sunny and windy at times. At night it is below 50 degrees. She is curious and concerned because her other trees such as Crape Mrytle and Pecan tree are all showing new growths except this one. Any comments will be appreciated.
