Orchid growers are sometimes plagued with leaf splitting in their collection, particularly with phalaenopsis, paphiopedilums, and occasionally cattleya-types and others.
There are a variety of theories intended to explain the reason for such issues, many relating to humidity, light levels, dehydration followed by heavy watering, and watering frequency, but I believe there may be a nutritional basis, either alone or in conjunction with other parameters, so the goal of this is to collect a wide range of experiences to see if there is any correlation.
If you have an interest and can spare a couple of minutes, would you please submit your "leaf splitting" experience using the
form here?
I'll let it run for a week or more before I tabulate and share the results.
Thanks
