Plant tissue analysis is around the corner. Remember to send a sufficient amount of leaf material as suggested in the plant analysis guide or a rule of thumb would be a double fist or softball size of plant material when squeezed together. Do not ship in a plastic bag. Be sure to order you plant analysis supplied from our website or call the lab.
