Check for disease. These do grow but in spurts. Be patient. If it is healthy, then there's no problem. Continue to water well. Do not over fertilize which can cause chemical root burns. Most especially don't fertilize on hot dry days. Top dress with some mulching and perhaps some composted manure and these trees will flourish.

thanks for the response.... i have covered with mulch, to retain moisture in the summer months.... i just thought after two springs i would see some new growth.... will have to be patient!

Water, water, water. My cedars grow fast in wet clay soil but so slow in sandier dry soil.

But don't over water. I've lost a cedar due to it getting water logged becuase rainwater from a neighbor's downspout drowned it.

Look at it his way. Once established to your desired height, the slow growth will be a positive point requiring less trimming.
