bought 2 year old jacaranda from a nursery in western australia and planted in clay soil in yallingup western australia. Only planted 6 weeks towards end of summer and now April 25 2019 and leaves are turning brown. Planted with sheep manure and mulch
Answer:
Hi Susan, My best guess is that the combination of fertiliser (sheep manure in your case), and insufficient water has done the damage. You probably have a water-repellant soil as well. Get some Saturaid from a hardware store or nursery, dig it into the soil a bit then water the bejesus out of it. Water it once a week until Spring. I doubt that green leaves will return until maybe even November (if at all).
Please remember that fertilising at planting time often kills plants. Better to do it about 2-3 months later. Don
