Bethlehem PA here. I used the Mag 3 to excellent success, but listen to Bestlawn...she knows what of she speaks. Perhaps you could kill just a little section of it, perhaps 2 x 2 or so, and see how that goes? Hopefully that's not too much to experiment with, although it could be a bit unsightly if those trees cause it to fail. But if it works, in fall of 2009, let it rip. I have had a soil test which shows my soild to be lacking in nutients, while PH is on the low side of ideal. It'd be a good idea to spend the spring and summer correcting these issues as they're impacting your existing grass. It could certainly be that your current grass would look wonderful if fed and the pH adjusted--and no other addition is necessary. (Also, mow high and water rarely...we'll all be happy to expand on that if you need more information).

Michelle, Maybe the link below will help. Terry Here is a link that might be useful: Thunderbird's Program Interface

With the exception of some hydrangeas, such as the white varieties - most hydrangea color naturally depends on the PH of your soil. The more acid your soil, the more blue. On the other hand, if your soil is alkaline, your blooms will be pink. To change, or speed this process along, add a solution 1/4oz. of aluminum sulphate and 1/4oz. sulphate of iron mixed into one gallon of water for blues. Apply up to two gallons in spring and fall. A stronger solution can have a negative effect, so do not exceed recommended dosages. More is not, in this case, better. To encourage pink, add lime. The pink will not appear right away but over time. --------------------------------------------------------------------------------
