Hello, I'm having some trouble figuring out what's the issue for my plants, started with a northern highly blueberry shrub, every couple of days I get about four leaves turning brown just like in the image and they turn brown really quickly. (Takes about a day for half the leaf to go brown, down the midrib)
I've tried these in the past two months:
- keeping the plant leaves dry placed in a ventilated area just in case it was fungal.
- Reducing watering to only water when soil is try to avoid overwatering and underwatering.
- increasing amount of fertilizer slightly to ensure plant has sufficient nutrition
- Neem oil sprays to remove pests
Today, I found a similar leaf on my garden mint that's exhibiting the same brown patch on the tip of the leaf, worried it will start spreading.
Has anyone experienced something similar?
Understood, thank you so much for taking time to explain. ๐๐ป
