Roaches vs. Your Orchids: Tips to Stop Your Plants from Getting Munched on
Cockroaches are among the greatest pests with which you will have to deal in growing orchids. They can do heartbreaking damage in a scant few nights if not intercepted and killed.
Why do cockroaches pose such a big problem? The answer is that one of their favorite meals is a potted plant's tender young roots and flower stems. It is not unknown for the roots of a plant to be completely chewed up in one night by roaches.
How to fight cockroaches effectively is one big topic. People have been fighting with them in their homes and kitchens for centuries, and we will probably be fighting them for centuries to come. They have evolved to be incredibly successful in living amongst us and in resisting extermination.
A wide array of poisons have been marketed in an attempt to control roaches. If you go the route of putting out poison, you must of course only use the ones that will not do damage to your plants. Check out the garden supplies aisle of your local hardware store.
For a less potentially risky solution, many growers have had success using boric acid, sugar and flour mixed with water to make a paste. The paste must be spread in every possible crevice to be effective. Some people even make sure to put some behind their light switch plates in their walls. To be completely safe, though, don't allow any of this paste on your plants themselves.
You could also set out a few those "roach hotels." These will catch many roaches and keep them from getting to your plants in the first place.
But really, the only way you can hope to keep roaches reasonably controlled is to hunt for them by both day and night. You should especially search for them on and around your plants in the evening, using a flashlight. They leave their hiding places in the evening to seek food and it is then that they are most easily caught and killed. Don't forget to move your pots and baskets around to uncover ones that may have run into hiding from you.
A good guide to orchid growing will have many more tips and suggestions for making sure that pests such as roaches don't destroy your plants. The most complete guide to today's orchid care, in my opinion, is Orchid Care Expert by Nigel Howard, which may be downloaded from the web. Mr. Howard's guide is a complete course in itself, great for beginners as well as those more experienced. Also, be sure to visit the Orchid Secrets web site, which has an ever-growing database of articles on all topics of orchid cultivation.
