Worms in my Yucca Cane plant
Comments (3)You can check the roots & change the soil. The roots can be cleaned off with a power nozzle, & any unnecessary root material removed. The roots tolerate trimming, & it is a good idea to cut away all bad roots while transplanting. I have not seen white worms with fungus gnats, but from the posters above it looks like it is possible. Make sure they are not termites....See MoreWhat are these red spots on my rose canes and are they bad?
Comments (26)The spots pictured could be nascent canker, but are probably something else. Older rose canes change color in spring, and in the process often look specked and splotchy. Also blackspot fungus can make red spots on the bark--it's the main way that BS overwinters. (The spots do not damage the cane, but generate spores that will splash up to infect the leaves in spring. For this reason, severe pruning will delay the onset of blackspot for a few weeks.) There are probably many causes of red spots. True cankers may start with such spots, but develop into larger areas of dead bark, black or brown, usually with concentric zoning of two colors. Do an images search for rose stem canker. There are several kinds. Spores of fungal diseases are ALWAYS present in a rose garden, so sanitation efforts have limited value. It's possible to do a lot of damage with the pruning shears in a panicky attempt to prevent the spread of imaginary disease or a futile attempt to prevent the spread of a real one. (Fungal diseases take hold and spread mainly on account of very particular weather conditions.) I never prune out healthy wood because of red spots, and my roses have done well for decades. I don't prune out every actual canker, either. The rose's immune system will usually contain the canker until it becomes inactive. A rule of thumb you'll find in older rose books is to prune if the canker has girdled half the circumference of the stem....See MoreYucca Cane - Yellowing Dry leaves
Comments (1)That it totallly normal It loosing the older leaves. Oh no. I was going to suggest to wait and re pot in spring. They take better then. Kepp it dry, They like it much drier in the winter. If you have watered it one already after repotting it's best to leave it alone until your see new growth....See MoreWhite stuff on my Wiegela
Comments (1)Took a closer look...they're borers. All the canes that didn't make it through the winter are bored into. I just finished cutting them all off. Other than that, what should I do? Will they be back?...See Moreperlite
