help!!!!!! english ivy dying !!!! again!!!!
Comments (6)Ivy is really not a very good houseplant. It does not like heated indoor winter air, which always seems to lead to spider mites. I have found Algerian ivy is a little easier to work with (it has red stems and is rather pricey). Plan to spray regularly with a horticultural oil to keep the mites at bay. Life will be a lot easier if you try a pothos instead. Watch out for cold damage when you buy any plants in the winter. Taking a plant out of a nice warm greenhouse into a frigid parking lot and car can cause damage and even death fairly quickly....See MoreMy English Ivy has Spider Mites
Comments (8)My goodness, I couldn't agree more with Rhizo about the Ivy being a spider mite magnet. I don't have English Ivy - or any type of Ivy - in my home either for that reason. And like Rhizo, I will also suggest commercial insecticidal soap, which will be much more effective. You can repeat the application over a period of time and check your plant to make sure that there is no more mite presence. You will appreciate having used the insecticidal soap; it really works well with spider mites. I have made a conscious choice not to have Ivy in my home anymore because I'm not in the mood to deal with mites but theyÂre such beautiful little plants that you canÂt blame one for wanting to own them. And it doesnÂt have to be a constant battle with mites. A friend of mine who loves those little plants has a whole collection of them and she hasnÂt had to deal with spider mites for ages. But she is very persistent about keeping the mites at bay...misting, rinsing the plants under her sink, maintaining humidity levels at healthy levels, etc, etc... She wants to have those plants in her home and will do whatever is necessary to keep them healthy and pest-free. I guess IÂm just not in the mood to put all that required effort or maybe I donÂt like Ivy enough to want to :) Maybe that's why mine in the past would get infested often...not enough effort!...See Morespider mites and bleach
Comments (16)When I was taking OH, bleach water was all we used as fungicide, miticide, any type of bugicide on our cuttings, pots, tags, clippers, shovels, whatever. It was the recommended prescription from Cal Poly about 20 years ago. Any OH student would use bleach, now they use chemicals, and the plants seem to do worse for it. Don't use it on soil, because this kills good microbes, but you can bake your soil, or use certified weed free mix, this is usually pre-baked. Use about 1/4 cup of bleach to 1 gallon of water, but do not soak more than 15 minutes and rinse all the bleach off the plants. This is just strong enough to leave a slime on your hands. Then keep your plants isolated from the other plants. Another thing to try is veggie wash. Spray it on then let it sit for about half an hour, do not let it dry, but keep it wet, then rinse it off and dry the plant....See MoreHas anyone ever completely eradicated spider mites from an ivy?
Comments (67)Oh my goodness aruzinsky, apparently I've offended you - you're so upset you published your objections twice. Seriously, though, "people like me?" I'm not presuming to "speak" for anyone - simply using the word we in a general sense, like "we take care of plants," or "we work hard;" like a chemist might say of him/her self and others in the same profession, "we do experiments to learn about the effects of chemical substances." In that sense, "we" aren't likely to talk about eradicating insects, because eradicating is defined as "to get rid of completely," and "we" know that is impossible, and control is the best "we" can do. As in the article you site, where the researchers repeatedly use the word "control." However, to be more precise, "we," be we growers, plantcare companies, or even retail stores, generally just talk about "killing" mites, and what products and processes kill them best. If people want to use chemical controls, fine by me. I thought all the discussions of chemicals might be a little off-putting for some people, so I merely wanted to throw in my experience of success using a simple, inexpensive, easy to acquire, and safe treatment. I don't think it's a "fault in my thinking" to say I never observed damage to a plant. The point with interior landscaping is not to grow plants as big as they can be, but to keep them looking beautiful. Spots, discolorations, stunted leaves, and so on, would not be beautiful, and these things I did not see. Some of these plants were in my care for several years, and did not show any negative effects. Informal observation has value, too. After all, I don't need to conduct detailed astronomical observations to be able to say with reasonable certainty that the sun will come up tomorrow. Spider mites, as well as other pests commonly found on indoor plants, are a fact of life. (Of course, if you live in an area where the winter temperatures are regularly below freezing, you're not going to be seeing bugs floating in from outside. Thanks for clarifying that.) That doesn't change the fact that they do float around when temps are warm, and they can infect anyone's plants at any time. Some people might appreciate knowing they have alternatives other than chemical insecticides for dealing with them, call it what you will - eradicate, exterminate, eliminate, extirpate - the point is to get the little buggers off your plants....See More- 17 years ago
