Tree Planting Services

We are experts when it comes to tree and shrub planting in upper Westchester. Knowing what tree to plant – and how and where to plant it – can make all of the difference in whether it thrives or dies.


Our certified arborists can help you choose a plant or tree species that will grow faster and live longer on your particular landscape. We factor in local climate and soil conditions, deer and tick control, as well as your short and long term property goals.


Trees and shrubs you plant on your property can be considered a lifetime investment. Planting them properly is the first step to ensuring they have a healthy future.
