Dont let Bugs bug You!
Spring is finally here, as evidenced by the six inches of wet snow we received last Sunday. Ah, Chicagoland! Despite the weather, our plants are beginning to put out their new root and plant growth. With the warmer spring weather will also come bugs! Aphids, spider mite, scale and mealie bug will all attempt to squeeze their way into our plant collections.
Don't panic! Bugs are just an annoyance that we must deal with if we are to continue to reap joy from our hobby! They are usually easy to kill if found early. One of the best things you can do is to scout your plants carefully every week or so, perhaps during the watering process. Make sure to check the underside of the leaves and in the the nooks and crannys within the plants growth structure. The bugs will tend to hide where they cannot be readily seen.
If you see a bug, simply spray your plant or wipe off the leaves with isopropyl alchohol. The Bayer brand "Rose and Flower" insecticide we carry (blue bottle) also works very well on most insects. It comes pre-mixed, thus is "ready-to-spray" right out of the bottle. We also carry "Bon-Neem," an insecticidal soap derived from Neem Oil which is non-poisonous and also "ready-to-use" without mixing.
If you have a plant that is heavily infested with insects, take it out of the pot and remove all of the media from the roots. Dunk the plant, roots and all, in an insecticide solution (don't forget eye goggles and rubber gloves to protect yourself). Swish the plants around to be sure that the liquid penetrates all crevices within the plant to ensure pest eradication. Wash out the pot with a bleach solution and repot the orchid in fresh mix.
If you have a widespread problem, we have a host of other pesticides, such as Orthene systemic liquid, Malathion, Systemic Granules, etc., which work well when used as directed. Our pest control class (April 11th at 1pm) here at the Oak Hill Gardens will cover this topic in more detail.
By watching your plant closely and catching sight of pesky bugs early enough, you can maximize your bug control efforts and add this to your ever-expanding list of orchid growing skills!
Good luck!
