This could not be easier to use.
We tested this out with two of our many orchids, then waited to make certain they did not have a bad reaction.
Both appear happy and healthy, so we can report this is compatible with the Phalaenopsis varieties.
To deliver this fertilizer to an orchid, you simply snip the tip, then invert the plastic tube into your plant's container.
It then slowly empties itself out and you return only to dispose of the product.
I would consider this a good choice for perking up old, tired soil, as well as for encouraging blooming or trying to help an ailing plant.
With a room full of orchids, this has been a perfect fit for our plants.
These bottles offer a very easy to use way to show your orchids a little extra love, recommend.
