The answer to this question depends on where you live. Although popular opinion says that the best time of year to plant in Northern California is during the spring, it is the fall that is the best planting time. This allows the plants to receive the water they need from the winter rain and secure their roots. Bay Area winters are reasonably mild, so cold will not damage the new plants. On the other hand, spring planting can result in the summer heat, causing them to wilt and die. Of course, nothing is written in stone, and we will be happy to work with you at any time of year to create your landscape.
