White Spots On Tomato Plant Leaves - Knowledgebase Question

Question by LeeAnnAnder

I have a cherry tomato plant I planted in a container on my apartment patio. I am noticing white spots on some of the leaves that start near the center of the leaf and grow out. The plant otherwise looks really good with lots of flowers and cherry tomatoes.

Thanks much,
LeeAnn Anderson

If the white spots are spreading, it could be a fungal disease such as powdery mildew, or it could be sunburn. Check to see if the white areas have a texture, or look like they've been dusted with powder. If so, remove the leaves so the fungal spores cannot infect the healthy plant parts. If there's no texture to the spots, they're probably sunburn. I'd remove the affected leaves which will open it up to better air circulation and sunlight penetration. Make sure your tomato plant gets full sunshine and adequate water throughout the growing season. Hope you have a terrific harvest!
