Hi, I have a nectarine tree that is riddled with leaf curl. I didn't spray it before bud burst and now I'm worried if won't survive the summer. What should I do? Many thanks
This article should have your answers:
Has produced fruit in past nice clusters of small fruit appearing, however a small number just dropping not sure what to do?
It could just be that the tree is thinning the fruit that it can't support. Often fruit trees bear more fruit than the tree can sustain. These articles should help:
Dying means bark peel back, oozing of sap, etc etc
Unfortunately, your photos did not come through. I am unable to see the extent of the damage.
It does sound like it is on its way out, though, unfortunately.
In the meantime, this collection of articles will help you with the care of the tree for the next one:
I planted a couple white nectarine trees last year and now have small fruit growing, in the spring I sprayed with copper and also horticultural oil, but at this time of the summer should I spray anything else and is it bad to spray when there is fruit growing? Thanks -Dean
Usually, treatment with oils or copper should be done during dormancy, or according to the instructions label. Each product can have a different potency and set of application rate and time. I would AVOID a summer application, however!
I came across your article on Panamint nectrarine. You mentioned Panamint fruits does well (fruiting) in southern California. Plant online description says for USDA zone 6-9. I live in USDA 10 zone in southern cali. Do you know if it good option for 10 zone?
The number of chill hours in your area will determine if the nectarine tree will do well. I included a fact sheet that shows the number of chill hours for San Diego. You may not get enough chill hours depending on where you are. Panamint needs about 250 chill hours. You may want to call your local university extension office or a local nursery for their recommendation.
