This JBP was collected here in Brazil on the ending of our winter, 5 weeks ago, i started with slow realease fertilizer the day after collecting it and 1x per week foliar feeding fish and kelp fertilizer. It stayed 3 weeks on partial shade and the last 2 weeks it got full sun. It started to push new needles but dropped several old needles that dried, also some of the internal branches and needles dried and fell too. Does the tree looks healthy? This new growth means that im safe? how long till i know that the tree will survive collection? also there is a branch that appears to have needle cast or something, should i spray a systemic fungicide, daconil or copper?
