Snapdragons require low to medium fertility levels between 100 and 200 ppm N. Optimal substrate pH values for snapdragons range from 5.5 to 6.2. Snapdragons can develop high substrate pH disorders if the substrate pH rises above 6.5. Inhibited iron availability due to high substrate pH induces interveinal chlorosis and stunted plant growth.
