Garden compost
One day I decided to use the pulp as compost in my flower bed. A month or so later, my mother-in-law came to visit. She went out to tend to the flowers and later asked when and why we planted tomatoes in with the flowers.
Needless to say, we hadn't intentionally planted tomatoes, but was a result of seeds from our juice pulp compost. Now we have fresh tomatoes for our salads and juice.
