"pac choy is a good substitute for lettuce." Got me on that one... what is a good substitute for lettuce? Wife likes spinach best but I cant seem to get that to grow very well and have tried Malabar Spinach...which grew well but we its a little "strong" taste for us so still looking for a substitute. I just put a strip of arugula, red leaf and romaine in the ground so waiting on that to come up.
I gave up on spinach. 3 weeks ago my neighbor planted spinach it looks good. I think I just learned how to grow spinach. LOL. He sprayed with 7 dust $20 a gallon at Walmart. 7 dust worries me I never put toxic chemicals in the garden.
