Current thinking on slow release fertilizer

[ArronOB]

Hi. I have typically used soluble fertiliser for my orchids. Now I’m looking for an easier way to do this.

So I’m wondering what the current thinking on slow release fertilisers is. I have done a search of the forum and got lots of hits, but I ask again because I know that ideas change over time and new products appear.

So, I grow mainly Oncidium and cattleya type orchids, mostly in shadehouses, in slotted pots, in bark. Some overhead watering by sprinkler, some by handheld hose. I generally water 2 of 3 days in summer, and maybe weekly or less in winter. I take a few plants inside for 2 months or so over winter, but space is limited. I also have a couple of dozen hardier plants in baskets or slabs that grow outside year round, hanging in trees.

Anyone using slow release? Have any thoughts or advice about suitability for my setup? Recommended products or ratios?

I have never tried it myself.

Thanks
Arron
