Otherwise, either type is acceptable to backyard growers. One odd problem is the fact that the trunks have a catnip-like aroma which cats love to rub against. When plants are small, this can be a problem as they can rub off any new shoots which emerge in the spring. Garden snails can also be a problem on younger plantings. Other pests include deer browsing on the leaves and gophers attacking the roots.
Scale insects can also be a problem if populations build up too extensively.
Where present, root-rot nematodes will reduce plant vigor. Ripening depends both on cultivar grown and local climatic conditions. Commercially, the fruit is harvested mature-ripe when its soluble sugars reach 6.5 brix on a refractometer. For the home grower it is best to wait for harvest until at least November 1, but November 15 would be preferable. Seed inside should be fully black by this time.
