Nectarine tree is dying, I think…
We just planted a nectarine tree this spring, about 8 ft tall. It's in the vicinity of a large redwood tree. This spring, it sprouted nicely, leaves were coming in, flowered beautifully and tons of tiny fruits. Then starting in April, the leaves started dying a bit so we toned back to deeper, less frequent watering. In the meantime, squirrels ransacked all the fruit. But now, the leaves are all very drippy and on the verge of browning/falling off. I have no idea what is going on and would appreciate any ideas!
Nectarines are certainly delicious, but growing they requires a certain amount of care and expertise. This article has basic information: https://www.gardeningknowhow.com/edible/fruits/nectarines/growing-nectarine-fruit-trees.htm
There's more than one condition that could cause dripping. Your best option is to take some samples of leaves and twigs to the local Extension Service, who will be able to diagnose the problem and recommend treatment.
