I have planted lettuce (mixed salad leaves), spinach (some standard variety) and dill (also standard) in three baskets that hang on the fence. All of them have germinated nicely, but all have been sitting at the same "one tiny set of secondary leaves" stage for about two weeks now, despite the recent good weather. Could anyone please tell me why?
Could it be because the soil is too wet? The baskets are of the type where the bottom 1/4 of space or so is sectioned off to hold water that then seeps up into the soil. The soil in the baskets is always moist (but not sopping wet) despite me never watering them.
The soil itself had loads of compost in. The baskets get full unobstructed sunlight for at least 2/3 of the day.
It is because they are too crowded? I was planning to thin, but when the leaves a big enough to make at least a small salad with. I put the stuff in the baskets in the first place to keep it away from slugs.
