With fall now in season, The days are turning shorter, the evenings cooler, sending a signal to plants to slow down. Now’s the time that plants concentrate on what is underground–their roots.
In the fall, plants’ needs are different than in the spring and summer. In warmer months plants are concentrating on leafing and blooming, but in the fall, their energy turns to the roots. They no longer need food (nitrogen) to stimulate upper growth. What they need is food low in nitrogen, which inspires upper growth, so that they can concentrate on a stronger root system. Trees, shrubs & perennials generally experience a burst of growth when they are fed with fertilizer high in nitrogen. For example, if the growth bursts in October, the new growth will get zapped by cold weather that can damage the entire plant.
