In order to promote uniform ripening of the tubers, haulm reduction can be carried out two to three weeks before harvesting. Instead of or as a supplement to chemical siccation, GRIMME offers a sustainable solution of haulm topping. By using a haulm topper, the haulm of the potatoes is mechanically crushed and deposited between the ridges. Careful placement of the haulm between the ridges is important.
