For the old leek should not be excessive topdressing watering, so as not to grow, in time after the rain drainage, to prevent stagnant water rotten roots. Before the rainy season, the leaves should be properly harvested to avoid lodging and rot, but the leaves should not be overweight, so as not to affect the normal growth of leeks.
