Q.Dried up sections of potted Spanish lavender
My potted lavender topiary was doing well outside. I made sure soil was alkaline and I did not water frequently. Blooms died off in fall, so I used your website instructions and gave her a reshaping down to just above 2 inches from woody area. I brought her inside when winter came. She was in a sunny window area with minimal watering. I sprayed for spider mites. She did well for s month or two, then the leaves shriveled in areas. Now she is mostly like this grayish wilted leaf look. I moved her to southern sun exposure and later off the watering. I cannot stop the progression of dying leaves. I don’t want to loose her, she is my favorite plant. Any suggestions for last minute salvage would help. Thank you.
Did you spray because you suspected spider mites, or that the plant already had them? If there were already spider mites, then this could be a problem. As they suck sap, they also introduce their own poison, which if left treated for too long will destroy a plant beyond repair. If you water with a few drops of rosemary oil in the water, then this will deter spidermites. You should only have to do this once a month or less. I would say just keep the soil slightly moist with a short dry period in between. This might keep it alive until you can put it back outside.
