Last year we bought a passion flower and it flowered, and two of the flowers developed into seed-pods. At the end of the fall, I kept the seed pods, and, later, planted them in potting soil. To my surprise, they have flourished and I now have about eight or nine shoots, some nearly 5 feet tall, growing up a makeshift set of sticks and twigs in a South-facing room. However they have run out of space and height, and I guess there is at least two more months before they could be moved outside.
At present I am feeding them about 100-200 ml of dilute plantfood/water per day, and they seem to take as much as I can give them. Pot is well drained with marbles at the bottom and I see no moisture coming out so they are drinking it all.
I would be very grateful if you could suggest some way of caring for them that will somehow limit the amount of space and height they want without starving them, and also any suggestions for other things I should be doing. Our hope is that they will make it through till end May when we can move them outside into the garden where there is a good climbing fence for them.
