Preparing orchids to come back inside

[Orchid Whisperer]

I would follow package directions, as there are products that are meant to be applied as a spray, watered in with a hose-end sprayer, or applied as granules. Alternatively, the St. Augustine Orchid Society has a downloadable sheet which includes mixing proportions for a few commonly available imidacloprid products.

I have a Bayer Advanced 3-in-1 product that is packaged in a hose-end sprayer, I worked out the dilution for applying it with a pump sprayer, and apply the product to the top and bottom of leaves, stems, and drench the potting medium.
