5) Harvest! So all you have to really do is harvest. If you dont harvest, the plants will grow too densely, go “leggy” with tall, thin stalks and small leaves. This means that they will loose productivity and run to seed early. So you have to make sure that you always pick enough to give other plants a chance to come through. The space left by a harvested plant will be quickly taken up by its neighbours. This way, there is never any empty space or bare soil.
