spider mites on ivy (again!) and kalanchoe root thingies
What can I do about spider mites on ivy? I love ivy for a houseplant, but every time I have some, the spider mites find it. I've washed it off with water while rubbing the tops and bottoms of the leaves and spider mites are back. I bought a beautiful hanging basket of Jubilee ivy and hung it in our bathroom window and I saw it has spider mites, too so I put it in the shower under water. What now? I read that ivy doesn't do well with pesticides. Is this true?
Also, I purchased several kalanchoes in the past year. The oldest one that I've had for probably a year now has what looks like little white aerial roots sticking out. Does this mean that I need to cut those sections off an propagate? I was hoping to get a nice big plant. It's currently six inches high and the widest point at the bottom is six inches across.
Thanks for any advice you can lend.
