Larger than microgreens, baby-greens are plants that have developed at least their first set of true leaves or more, but the number of species grown as baby-green is way smaller. Usually, the plants used to obtain baby-greens are lettuce and other salad greens.
Plants grown for baby-greens are started in the same way as those cultivated for adult-greens, though you will not need as much space between plants if growing exclusively for baby-greens. A growing medium that is well-drained and rich in organic matter ia a good base for most greens. Sow the seeds in large and shallow trays, with drainage holes in the bottom.
Once the seeds begin to germinate, moderate watering but do not allow plants to dry out. Once the true leaves start to form, the plants will need good amounts of water but will not tolerate drought well. Keep soil moist, but not too soggy as this will promote root rot.
Harvest your greens when they reach about 15 cm tall, use scissors to trim them back. Just grab a clump of greens with one hand and cut them off 2-3 cm above the soil line.
For a steady supply of greens, sow seeds every two weeks or so throughout the growing season. Any sunny and warm place will do. If the weather is too hot, take them away from the window and find a more sheltered place. If you have enough patience, you can get a second crop from the same set of plants, although it may not be as rich as the first harvest. For this is it better to feed your plant with an all-purpose fertilizer to help promote new growth, but always avoid applying the fertilizer directly to plant or leaves.
