A step-by-step instructable on growing Ridge Gourd at your home garden... These methods apply to other varieties of gourds like snake gourd and bitter gourd also.
Step 1: Seeds
Either you can save seeds from previous year's fruits allowing one or two to fully mature and dry in the plant itself or you can buy seeds from shops.
in the first picture you can see the ridge gourd seeds being collected from last year's dried fruit. The seeds are protected by the sponge-like network of fibers. You can extract the seeds from the fruit whenever you are planning to plant.
The second picture shows the seeds stored in cow dung. You can harvest the matured seeds and press them into flattened fresh cow dung and dry it in shade. Cow dung is natural protector and will not allow any pests to damage the seeds. You can break the dried cow dung cake and take out the seeds any time.
The third picture is of the store-bought seeds. These seeds are treated with chemical pesticides and are artificially colored to show the presence of pesticides. Take care while handling store-bought, chemically treated seeds and wash your hands thoroughly afterwards.
