I wanted to try and grow from seed this year, some veggies and herbs, in my windowbox. Its east facing and gets full sun all day (yanno, when that occasionally happens in van this june! ;-) ). 2 concerns: 1. The cilantro is going red and Im not sure if its burnt, a red like hybrid or maybe theres not enough depth of soil? I tried splitting it out to other planters (still same dirt) and some are on the verge of bolting and others are totally stagnant. 2. I planted a tonne of lettuces and some are doing superbly and others are from 1/8" to 1/2" high. All the same seed, soil and windowbox in the beginning. I've done some thinning to see if I could encourage some growth. Sizes are definitely a mystery! Any ideas or suggestions?
