As others have stated, No nitrogen. 0-20-20 or 0-25-25 is a great place to start. If you have a fertilizer plant close to you, they will have something close on hand. Clover makes it's own nitrogen, so when you add nitrogen in your fertilizer you are feeding grass and broadleaf weeds. If you can find 0-46-0 and 0-0-60, this would be an even better alternative to 0-20-20. The 0-46-0 would give you more than twice the phosphorus and 0-0-60 will give you three times the potassium per bag.
