Peachicks need to be kept in a brooder until they feather out or until the brooder temperature meets the outdoor temperature. Each week that a peachick is in the brooder you should lower the brooder temperature by 5 degrees. This will ease the peachick into lower temperatures with the least amount of stress possible.
Step 3. Plant azaleas, hostas, astilbe or ferns underneath the pine tree. All of these plants love shade and acid, and have foliage that will provide visual interest.
The easy answer is just don't grow grass there. Grass doesn't like to grow under pine trees, so why force it. The soil is acidic, it can be messy, there is little sunlight and competition for water is intense. Create a bed of mulch or pine straw preferably to the drip line of the tree.
