I really am frustrated not able to plant anymore, I also planted vegetables before including a yam tuber in a sack of sandy soil, more sand than soil then I let it creep to a tall Santol tree where it got its sunshine. Below I water it just to make the sack moist. The Yam tubers really grew big too after a year. I harvested 4 and a half kilo in one yam tuber alone.
I never had gotten that repeated because my father who is hack-happy fell the santol tree later.

BTW, camote tops really is yummy in sinigang especially in shrimp sinigang.
