Putting the COlor in COlorado!
As the ground starts to thaw and spring is just around the corner, now is the perfect time to plant dormant trees, shrubs and perennials. Planting dormant nursery stock is a great way to get a jump start on the next growing season. Dormant plants don't have much top growth right now, but there is a lesser risk of transplant shock and more time to establish the plant's root system so your plants will be bigger and healthier come springtime. Check out the varieties of Flowers, Fruit Trees, Shrubs, Grasses and Berries at O'Toole's Garden Centers
