Landscape Logic: Fall is a great time to get going on perennials
It may be only be months away, but it feels like an eternity until we will see the peonies bloom again.
That’s a sad thought for many, but the good news is that we can get perennials off to a good start in next year’s growing season by putting in some garden work right now.
Fall is one of the best times to plant new and divide existing perennials — peonies, daylilies, Echinacea and all the rest. Soil conditions in the fall are usually better for digging than in the spring. Now, there’s no dodging the frequent late-season snows and the muddy conditions they produce.
Fall planting also gets the plants feeling at home in their new digs so the roots take hold and start growing. By springtime, the plants will be better established and may offer up more first-season blooms than if you waited until spring to plant them.
Here are some tips to for giving perennials a head start on the next growing season.
Divide and conquer
If you have perennials that have been in place 4-6 years or are overgrowing their space, then separate them with a shovel into two or more plants. This process rejuvenates the plants and also yields more plants to enjoy in other areas of your yard. All perennials benefit from this process and especially, ornamental grasses that sometimes appear to die out in the center.
Clean up the soil
Make sure the flowerbed where you add new or divided plants has been cleaned up of weed debris. Remove perennial weed roots, encroaching turf grass and old debris that may have seeds. The cleaner the bed, the fewer weed issues you will have next season.
Amend the soil
If you are planting an entire bed of perennials, then prep the entire area with organic matter such as compost, well-rotted manure or peat moss that is at least 6 inches deep. Dig holes that are two or three times the size of the root ball of the plant and plant with amended soil. The organic matter helps roots to become established and grow. Make sure plants are grouped according to their water needs to avoid over-watering some and under-watering others.
• Water plants after planting — and be prepared to check soil moisture throughout the fall and winter. Even though plants are dormant, they can still dry out and require water.
• Mulch around plants with an organic mulch such as shredded bark. This will help moderate the soil temperature and retain moisture throughout the winter.
• Fertilize with a root-developing fertilizer.
Next spring, you’ll enjoy the results of these late-seasoning gardening chores. Our plants always make us glad we made the effort.
