Hi! Thank you for taking time to answer my gardening questions! I'd love to stop by the office during your open hours. It is tough to make it happen given my work schedule. I am a new gardener and I absolutely love spending time with my plants! I even have 5 lavender in their second year : ) My challenge is troubleshooting the issues that are coming up. Yellow Leaves -Several of my plants have leaves which are starting to yellow -rosemary, peppermint, oregano, catnip, and thyme. I don't believe they are under or overwatered. I can't say that with 100% certainty, but I do feel the soil before watering. They are all in containers and all were planted with a mixture of soil-less potting mix, organic potting mix, and the rosemary also has some sandy loam. I had not fertilized them however, so I will try that. All of the plants are in a place where they receive plenty of sun. Additionally, many of the leaves have little white spots. The catnip has a leaf that looks as though it is being taken over by a white coloring -I suspect a disease is at play? I've attached pictures of these. Finally, my snap dragons succumbed to rust and I've now taken out the plants. (they were not in close proximity to the plants listed above) If I want to plant in the soil where the snaps were previously, or in the bed next to them, do I need to treat the soil? Can rust be spreading to my other plants? Thank you again, for taking the time to read and answer my questions. I hope to find some solutions which are organic and non-toxic. I would also love to check out any basic/beginner gardening resources you recommend. Thank you!
