|Are you supposed to fertilize perennials in the Fall. Was wondering because Home Depot is offerng $2 off fish fertilizer.
Also, my potted miniature arborviate's interior leaves are very yellow. Is that normal for this time of year or are they dying?
|Fertilizer encourages new growth which is not anything you really want your plants to do in the fall months. However, if fertilizer is on sale, you can purchase it now and save it for use next spring and summer. Just store it tightly capped in a cool location over the winter months. It is normal for the inner foliage on your arborvitaes to age and then be shed. If you lightly prune the outer foliage it will grow thick and dense enough to cover up the bare inner branches. Good luck with your plants.|
