I recently got 2 terete Vanda 'tips' from Hawaii - packaged by Kini PoPo for tourists. There are no roots. What should be done to help roots develop. So far I have them standing in small pots with some lava rock, charcoal and bark and watered them frequently.
Should they be drenched with liquid fertilizer? Or just kept in bright light - without direct sun - and given loads of water? I would really like them to root.
