What is the best time to plant perennials?
If you’re into GARDENING, you might WONDER when’s the BEST time to plant PERENNIALS.
Well, the BEST time to plant perennials is in spring or early fall. They like DAMP soil and MODERATE weather.
They’ll have enough time to grow their roots if you plant them early and late SPRING. It HELPS plants SETTLE before the SUMMER heat kicks in.
On the other hand, if you PLANT them in the FALL, they’ll go into a dormant stage. So that they get READY for the NEXT growing season.
I’ve planted perennials both in the SPRING and the FALL. I’ve FOUND that each season has its ADVANTAGES and DISADVANTAGES.
Make sure to follow the instructions on the plant LABEL. Remember to WATER them REGULARLY until they ESTABLISH themselves.
