Perennials are herbaceous plants that die back to the ground in the fall (leaves and stems). In spring, new growth comes from roots (bulbs/corm/ rhizomes) that have survived the winter. Perennials flower for weeks during their growing period and most live for several years. If a perennial has been growing in the same location for three or more years or if it has outgrown its location, it would benefit from division.
Plant division reduces overcrowding which can increase chances of disease and insect damage. It is also an easy way to propagate plants to use in other areas of your garden, to share, or as a gift!
The best time to divide perennials is in the spring when new growth is 2 to 3 inches or during the fall when foliage starts to die. Try to avoid dividing during the summer to reduce additional stress on the plants.
Begin digging up the root ball. Dig around the circumference of the plant several inches away from where it is growing from the ground.
Using this practice will help save as much as the root zone as possible.
Once the root ball is exposed, divide the clump into 3-4 even sections.
This can be done with a shovel, spade, or knife. Trim the foliage to 4-6 inches.
Plant the new divisions in prepared locations. Apply an even layer of mulch to retain moisture and water deeply. Water regularly to help establish.
- It's time to plant your cabbage, kale, collards, Swiss chard and leaf lettuce, through mid- October. Radish, spinach, turnip, salad greens garlic, and short-day varieties of onions can also be sown.
- Tomatoes and peppers can be protected from frost by covering them up when the temperature drops to extend their growing season.
- If you haven't started cleaning up old plants and weeding, now is the time. You can use the grass clippings and dead leaves in your fresh layer of mulch.
- Winterizing products are starting to appear in lawn and garden centers, but remember: fertilizers containing nitrogen, if applied in the fall, can injure warm-season grasses. However, potassium can be beneficial by enhancing cold tolerance of turf grasses. If a soil test indicates that your soil is low in potassium, it can be applied at a rate of 1 pound of potash per 1000 square feet of lawn. The only winterizing fertilizer you need on your lawn is one that contains potassium; and you only need that if your soil is low in potassium. Save the nitrogen for after green-up next spring.
*** If you haven't sampled your soil recently, go ahead now to avoid the peak season sample fee!
- Raise your lawn mower height by half an inch. This will allow your grass to root more deeply and store more carbohydrates going in to winter.
- Scout lawns for large patch now. Look for areas of thinning turf surrounded by a yellow or orange halo. If you aren't sure, contact the Plant Clinic by calling (910) 455-5873 or email photos to email@example.com
Trees and shrubs
- Fall is the best time of year to plant and transplant trees, shrubs, and perennials. It is also a great time to divide and replant perennials. Keep new plantings well-watered during their first several weeks as they get established.
- As perennial beds go dormant, consider leaving dead stems for beneficial insects to overwinter in and seed heads from plants like Sedum, Echinacea and Black Eyed Susans for the birds.
- Collect leaves and debris for composting, but don't compost insect or disease-laden plant material.
- Instead of bagging up fallen leaves, rake them over flower beds as a free source of mulch that will add nutrients to the soil, help prevent weeds, and regulate soil moisture and temperatures
