It is not necessarily a pest or disease issue that a plant foliage turns yellow. These disorders may be caused by environmental factors which includes too much scorching sun and lack of nutrients. But there is another natural factor that plants had to go through, AGING PROCESS. A plant, come to a time, will have to go. Our bitter gourd plants are going through just that. The whole plants, foliage and all are yellowing, new leaves getting a lot smaller, a few gourds are still dangling, probably the last. The two plants have been doing well, producing exotic fruits again and again. But now is time to go.
The whole bittergourd plant is yellowing.
Soon the site will be allowed to rest for a while, first to allow a few periwinkle to establish themselves and a few winged beans probably as ground cover to reestablish the nitrogen prowess of the soil. But again a plan may change....
