I am just curious if any one fertilize there's? if so what do you use?
root tabs or spikes or liquid.
Thanks

It depends on the case in example, but I am sure 99% if not more of people here fertilize. I do both substrate and water column ferts...

I have crypts growing well in both environments, substrate only and substrate plus water column fertilizers. Both are growing very well. I use Flourish tabs to fertilize my substrates but I don't treat the crypts any differently than everything else, I distribute the tabs evenly throughout the substrate regardless of the position of the plants.

I have C. wendtiis happily growing in my tanks. All fert is water column. I have always been uncomfortable with root tabs since invariably, they will be stirred up somewhere along the way when you uproot.

I use Jobe's fert spikes for lush palms and ferns. the npk ratio 16-2-6
