My spinach is very pale. What am I missing in the soil?
Spinach is a crop that needs a rich soil. It is very quick growing and therefore needs a lot of nitrogen. It is best to prepare the soil well and add plenty of well rotten manure and a base fertilizer such as poultry manure or bonemeal. If you haven't fed your spinach plants lately I would suggest that you use a liquid fertilizer once a week to help them along. You will see the leaves greening up after a week or two if they were deficient in nitrogen. A foliar feed will work even quicker. Take care to dilute the fertilizer according to the instructions as too much can do damage to the spinach leaves. Also important for growing spinach is to keep the plants moist and well watered otherwise they will tend to bolt quickly and won't produce much foliage. If the leaves go yellow you could have a problem with mildew. In than case there is probably not much you can do other than start again. It is hardly worth it to start spraying a fast-growing crop like spinach.
