Sugar Kelp

Cornell Cooperative Extension of Nassau County is conducting a FREE hands-on gardening experiment using Long Island grown sugar kelp biofertilizer to grow healthier, tastier tomatoes — and help improve Long Island’s environment!

As a participant, you’ll receive:

• Two tomato plants (one for kelp treatment, one control)
