my wonderful lady just picked up a vft for us...the problem is we r a little confused with proper care. Its a little guy, probably relatively new (2-3 inch stems w/ heads less than .5 inches). There are about 7 heads, and at different times different ones are open. We were curious if we should feed them or leave them outside for an hour or so so it can attarct its own food. If we were to feed them, what should we feed them, how often, and if we were to feed one head, is that considered feeding the whole plant? Do we need to feed each individual head? please help us!!!
