Hi i need help for identifying problem with color of leafs of my paw paw and lemon plant.
I need your opinion what is problem and how to solve it so my plants get again normal green color of leafs.
Paw paws are from 2 years old to 4 yrs old plant.
Lemon is grafted and about 3 years old plant.
Thanks
Looks like they need nitrogen
It’s nutrient deficiency but it is hard to say for sure what it is as some have similar signs and symptoms.
I’ve found Oragon State’s Mineral Nutrient deficiencies and Toxicities (with descriptions paired with clear pictures) a very good reference. You can check it out and compare with what you see on your plants.
Did you move the lemon from indoors into direct sunlight? I agree they look like they need nitrogen, but maybe if you didn’t slowly move them out, they are stressed from full sun.
My pawpaws did so much better when I put a piece of chicken wire around them, then used floating row cover to shade the plant.
Lemon is there outdoors on that sunny spot over two months.
I sprayed all plants with fe (iron) over leafs and add some in water and watered them, also i have given to all plants nitrogen with water, now i hope that will help.
In few days i will add some more nitrogen (UREA Fertilizer 46% N)
Thank you
