Even though this picture was taken several years ago, it won’t be long before many of us will be seeing this as we look out our windows and long for summer. I know it is a few months yet, but now is the perfect time to prepare your greenhouse for winter. It is still warm enough that you can move any plants remaining inside the greenhouse to the outdoors. This will allow you to give your greenhouse a thorough cleaning. Be sure to use a mild disinfectant soap to clean with. Get the mold out of every nook and cranny. I know that we all keep our greenhouses relatively clean, but this is just something that happens with all of the humidity. Check any corners or places where there may be potential leaks and be sure to seal them up. Clean your benches if you have any. Repair or rework your flooring, depending on what you have in place there. Check all lighting and electrical systems. If need be, get a certified electrician in to help you with this. You can never be too safe. Same with your greenhouse heater. Whether you have electric, natural gas or propane, be sure to check your greenhouse heat source and be sure that it is properly connected with no leaks. Also, turn it on and make sure that it works. You may have to go out later in the evening as the temperatures drop to try this, but trust me, it is worth the time and effort to do this. In fact, I think that checking your heating system is the most important part of getting your greenhouse ready for winter. I cannot tell you how many times I have received panicked calls that it is going to freeze tonight and my heater won’t come on. There is just no way to get parts or a new heater to you fast enough. So, even though we are still enjoying summer time temperatures, think about the winter and your greenhouse now.
