As the clouds pass over and deposit an inch or two of fresh rainwater over my garden, I can't help but wonder about the process of overwatering.
I notice that overwatering causes apparently random leaves on my babies to yellow. I'm wondering what technical process causes the leaves to yellow.
I can imagine 2 or 3 different answers to the process, but I don't know the correct answer. Perhaps the additional moisture in the soil waters down the mix and plants don't get enough nitrogen to their roots. Perhaps the plants can't control their water uptake enough to deal with the added water and it causes the leaves to "bruise". Perhaps the rainwater throws off the ph for a while.
Any thoughts? Is there a biologist in the room?
Cheers!
