Johnny's offers mixes of greens that can be harvested at 3 to 6 weeks for use as salad mix. Our mixes are balanced for color, texture, flavor and uniform maturity. Compared to lettuce, brassica greens germinate and grow faster but are more susceptible to flea beetles. To synchronize harvests of lettuce and greens mixes, plant one of our lettuce mixes 5–7 days before planting a greens mix. Mix leaves together post-harvest. Individual varieties in a mix may change depending upon availability, but will still provide the desired characteristics. All our greens and lettuce mixes are comparable to "mesclun mix" and "spring mix." For more information, see our Guide to Salad Mix Production.
