sooby said:The organic nitrogen in cut grass would have to be broken down by microorganisms before it will release usable nitrogen to the plants, so you might want to think about some purchased fertilizer in the short term. If you're trying to grow them organically rather than using "chemical" fertilizers, then this article may be of interest:

Great link, Sue! I saved that PDF. Pure organic farming is even harder than I thought!
P.S. I think that many plants suck the N out of their lower leaves when they are growing faster than their roots can take up more N.
It might mean infertile soil (add soluble N). (Maybe reduce leaching by adding compost or even some clay to very sandy or gravelly soil.)
It might mean that the top of the plant is just plain growing faster than the roots can keep up with (just wait for it to get back in balance? Next year amend the soil to be more hospitable to roots?)
It might mean some other trouble with roots, like being eaten by something, or drowning and rotting after the soil flooded and ran out of oxygen (improve the drainage and/or water less heavily).
