We have a little tiny piece of garden off our back deck which gets full sun and lots of love in the way of compost and watering when it needs it every year. Four years ago we planted a dwarf nectarine in that little space. I have underplanted it with various annual flowers including lobelia and impatiens and more recently ornamental grasses. Each year the nectarine has the most delicious display of blossom and then each year the leaves get black spot, the fruit get a brown rot and the Super Husband despairs of ever enjoying a ripe nectarine. We have tried spraying, removing and disposing of all the affected leaves, even replacing the bulk of the soil below. But to no avail. Has anyone ever had success with a dwarf nectarine? If so - what is the secret?
