You need to check your ph with a meter, soil conditions are different in every area, even in different parts of your yard. In existing beds like Rita has with companion plants, this ph# may not be the best thing for those other plants.
Back to the seedlings
After the seedlings are planted, I apply Snapshot or Preen to all the beds and walkways to slow down the weeds, weeds are a year around problem here being we have little winter. I also have to apply milorganite to the beds to keep the rabbits out for a couple months, you may not have this problem, they say this also helps keep the deer out. After a couple of months the foliage will be tough enough the rabbits want eat them.
For the first two weeks after planting they get nothing but water every other day. Water is most important thing for this early growth. After two weeks I start applying a water soluble fertilizer at a rate of 1/2 oz to the gallon. This is sprayed over the foliage every week from now til bloom time, then every other week.
