My cilantro is reddish-yellow. I grew it from seed, it was doing great,
growing fast. But something happened and now it is reddish-yellow. I
have not done anything like fertilizer nor water manually. Here in
Maryland, there has been plenty of rain during the last 4-weeks but it
has been cold --avg day temp is 70 where norm is 80 for Maryland.
Nights have been 50.

I have 4 (4x4) boxes and practice Square Foot gardening. Other herbs in
the same box as the cilantro, are stagnant but green, my radish seeds
have sprouted and onion sets are growing.

Any ideas on what to do with the cilantro? I mixed Leaf-Gro
(commercial, organic, compost) in with the soil before planting.
