I've been asked to bid a rather large job, if I get it it will be the biggest contract I've ever had. There are over 100 trees due to be planted, over 400 shrubs/bushes, several thousand square feet of ground cover, several thousand square yards of sod and several thousand bulbs to be planted. My concern is my lack of knowledge of proper planting, staking and initial care of the type and size trees that are called for in the proposal. I'm looking for information and advice sources on initial planting and follow up care for larger trees. Thanks in advance.
