|Just wondering when I can fertilize all my Perennials for the Fall/Winter. Can I do it now or is it to late?|
|Fertilizer should only be applied to plants that are actively growing. Feeding your perennials now won't help the plants - they can't use the food if they are not actively growing and you don't want to encourage new growth this late in the year. So, plan on feeding your perennials in the spring when the plants actually need the nutrients and can use them to their full advantage.
The only exception to the no-feeding rule in the fall is with turfgrass. The roots of grasses continue to grow while the ground temperature is still above 40F so grasses will benefit from a fall application of fertilizer.
Hope this clarifies things for you. Best wishes with your perennials!
