I am a little bit shocked, I must say, by the fact that house plants are “in” again.
Of course, for me, they never went “out.” I’ve been growing house plants since I was a teenager–which means at least 4 decades. That’s okay. I’m glad that something that I like is suddenly “cool” again.
But of course now everyone is online giving “expert” advice about everything to do with house plants. One of the most amusing ones–to me anyway–is how to bring house plants–or tropicals if we’re being exotic–in for the winter.
First of all, if you’re in the northeastern united states and you haven’t done this yet, be prepared for a major mess on your hands. It’s surely not too late to try to save some of your plants–but the later you wait, the more they have trouble with the transition. I generally bring mine in around Labor Day just to avoid that.
On the other hand, you could take some of the so-called expert advice and slowly transition them inside over a period of two weeks, spraying them no less than three times with some sort of organic insecticide.
I’ve never heard of such nonsense in my life. Clearly these folks don’t realize that the insects are going to go dormant in the winter (for the most part) and won’t wake up again (if at all) until spring.
They also don’t realize that some of these insects have eggs that can live up to 2 years in the soil–so you can spray your durned fool heads off as many times as you like and you’re not going to solve that little problem!
So rather than weakening your plants by thrusting them into the dark and spraying them with insecticide (even organic insecticide!), why not just hose the plants down with a good hard spray of water to try to dislodge anything that you can and then bring the plants in?
I am also no fan of the advice I have seen that suggests that you take the entire plant and submerge it wholesale in a bucket of soapy water. Again, why? This is like killing a flea–or an imagined flea–with a sledgehammer. You are weakening the entire plant and damaging its natural leaf coatings and you don’t even know if there’s a problem. Just. Dont’. Do. It.
Once the plants are inside, do watch them carefully to assure that you didn’t bring in any insects. You have another good month or so before really cold weather sets in. If you need to take a plant or two outside to spot treat with an organic insecticide, that’s certainly do-able. But no need to treat everything willy-nilly if you see no problems.
And continue to monitor. That’s what a good house plant owner does. The sooner you catch any problems, the sooner you can solve them. Both you and your plants will be happier that way!
