Vanda Blooming Problems
I have 7 vandas - all are kept outdoors on a screened in lanai in Naples, FL. Have had them a couple of years and they've previously done well but this year have struggled to bloom; several have sent out spikes that dried up and fell off before blooming. I water and fertilize once a week 7-9-5 alternating in a 3-12-6 once a month or so. Plants appear healthy with long root structures - they just seem to struggle blooming. Any suggestions on how to address this?
