3. Soil temps and germination. We have reached the minimum soil temp for germination for a number of our commercial vegetable crops. Beets, cabbage, carrot, swiss chard, lettuce, peas, radishes all have a 40 degree minimum for germination.

4. Cool season disease issues. There are a number of cool season disease issue that you might face. A general set of recommendations for avoiding these diseases include; Rotation, minimum of 3-4 years if a known disease is present. Minimize wounding of plants. Plant in well-drained soil. Avoid fields with a severe disease history.

5 High tunnel growers. Spinach can be produced nearly all year in high tunnels, creating new marketing opportunities. The question in early Spring becomes "when should I remove last Fall's crop?" Cultivar selection is important in these conditions as varieties have been selected to adapt to these unique growing conditions. Spinach that has reached a functional maturity (old) may look like they are exhibiting nutrient deficiencies but are not. These plants should be removed.
