How Long Can Beneficial Nematodes Be Kept Before Use

Question From: K. Rickett - Beverly Hills, California, United States
Q: My husband used my money (without asking) to buy nematoads and did nothing with them for months. If he puts them out now August 20 will there be any benefits? How long should i wait after to apply fall fertilizer? The system will not let me enter a Canadian postal code so i will use Beverly Hills but i live in Quebec

A: You will need to contact the company that provided the nematodes for that information. Best Nancy
