How can I influence my phal. orchid to flower for me? It has be about a yr. in a minute since it's last flowering. All it have been doing is growing more leaves and roots. Very sturdy plant. It get about 8-12 hours of table lamp from my growlight. I water the plant resembling every other wk, and feed it within between, much less next the recommend dosage on the fert. bottle. Like I said, the plant is very enormously healthy. I've also changed the bark/coal mix, bc i hear this stimulates flowering, but it hasnt!!!! Any help, please?!
