Wait it out...don't apply any more phosphorous (or add manure).

Try to add a N-only fertilizer.

If your plants show a zinc (bleached/faded) or iron (intervienal chlorosis) deficiency you can correct that with a foliar spray...and it may not be necessary.

Depending on how high it is, it could take years. Water and time will leech it out.

Soil naturally high in phosphorous is really quite common for many of us. It generally poses no problems to the plants, just to the ground water and to run-off unfortunately. It's one reason why many fertilizers are available with none in it.

As nc said focus on nitrogen and micro-nutrient additives only.

What is a good nitrogen number to look for on the bag? I usually get something like 29 or so for my lawn. I'm just not sure how much to add to my garden. Thanks

Not many straight N ferts come with a "number" on them because they are just nitrogen, little else.

As to how much to use? That's not an easy answer. Too many factors to consider like which form (liquid/granular. synthetic or organic) of fertilizer you use, how often you will use it, how it will be delivered, etc. They include such things as blood meal, fish emulsion, cottonseed meal, some manures, urea, anhydrous ammonia, ammonium nitrate, etc.

Research a bit into 'high nitrogen fertilizers'. Check out the article linked below for starters and this explanation of the various types. Selecting forms of Nitrogen Fertilizer

I will consider that my assigned reading for the night. Thank you!
