Ask most people when to plant and they will say spring. In coastal North Carolina that is the second best answer. The best planting window of the year opens in September and stays open until the ground gets cold, and almost nobody uses it.
We have been growing plants on this property in Jacksonville since 1968, and the pattern is consistent: the shrubs and trees that go in the ground in fall are the ones still thriving three summers later. Here is what to plant, when, and how to give it the best possible start.
Why fall beats spring in zone 8
Onslow, Carteret and Craven counties sit in USDA zones 8a and 8b. Our soil holds warmth long after the air has cooled, and roots keep growing whenever soil temperature stays above roughly 40 degrees. That gives a shrub planted in October something a spring planting never gets.
Do the arithmetic. A shrub planted in mid-October has October, November, part of December, and then February, March, April and May to build roots before it faces its first real heat. That is roughly six months of root establishment. The identical shrub planted in mid-April gets about eight weeks before July arrives, and it spends those eight weeks pushing leaves instead of roots.
The practical benefits stack up:
- Far less transplant shock, because the plant is heading into dormancy rather than into peak demand
- Dramatically less watering, since cooler air and fall rain do most of the work
- A root system already established when August heat and dry spells arrive
- More selection at the nursery and less competition for the plants you actually want
September: trees, shrubs and the fall vegetable garden
September is the single best month of the year to put woody plants in the ground here. Soil is still warm enough for vigorous root growth, and the worst of the heat has broken.
Shrubs worth planting now
Camellia sasanqua (which will bloom for you this fall, in its first season), holly, loropetalum, ligustrum, tea olive, gardenia, abelia, and wax myrtle. Wax myrtle deserves a special mention for anyone within reach of salt spray, since it handles coastal wind and salt better than almost anything else we grow.
Trees worth planting now
Red maple, willow oak, nuttall oak, live oak, river birch, and bald cypress for the wet corner of the yard that never quite drains. Crepe myrtle also plants beautifully in fall. Plant it now, and leave the pruning saw in the shed until late winter. If you take nothing else from this article, take this: do not top a crepe myrtle.
The fall vegetable garden
Early September is the window for collards, cabbage, broccoli, kale, mustard, turnips and Swiss chard. Lettuce and spinach follow a few weeks later as things cool off. Collards planted now will be better after the first frost than before it, which is the whole point of growing them here.
One thing not to do in September
Do not overseed a centipede lawn with ryegrass for winter color. The ryegrass competes with centipede exactly when centipede is trying to come out of dormancy in spring, and it is a reliable way to end up with a thin, weak lawn. Centipede also should not be fertilized in fall. If your lawn is struggling, the causes are covered in detail in our guide to centipede sod care.
October: color, containers and bulbs
October is when the yard gets its winter wardrobe, and timing matters more than most people realize.
Pansies and violas should go in from mid-October onward, once soil has cooled below about 70 degrees. Planted too early into warm soil they stretch, get leggy, and are far more prone to rot. Planted at the right moment they will bloom on and off from now until May, which makes them the longest-performing color you can buy in this climate. Violas take our cold snaps a little better than large-flowered pansies and bounce back faster after a hard freeze.
Also going in now: snapdragons, dianthus, ornamental cabbage and kale, dusty miller, and chrysanthemums for immediate impact. If you change out your entryway containers seasonally, this is the swap.
Spring bulbs need a plan. Daffodils, alliums and Spanish bluebells go straight in the ground from October into November and will come back for years. Tulips and hyacinths are a different story in zone 8: our winters are not cold enough to satisfy their chilling requirement, so they need six to eight weeks in a refrigerator first, then planting in late November or December. Keep them away from ripening fruit while they chill. Realistically, treat tulips as a one-season annual here and enjoy them for what they are.
November: the quiet month that pays off
Almost nobody plants in November, and it is still an excellent month for it. Trees and shrubs go in the ground successfully right through November and into December here, as long as the soil is workable.
- Refresh pine straw or mulch. Two to three inches deep, pulled back three or four inches from trunks and stems. A mulch volcano piled against the bark holds moisture where you least want it and invites rot and rodents.
- Keep watering new plantings. Fall and winter dry spells are real here, and a plant that went in six weeks ago still has a limited root zone. Water deeply during warm, dry stretches even in December.
- Know what not to prune. Spring bloomers set their flower buds in late summer, so pruning azalea, camellia japonica, forsythia, and bigleaf hydrangea now means cutting off next spring’s flowers. Save those for right after they bloom.
- Plant garlic and onion sets, and get the last of the spring bulbs in.
How to plant so it actually survives
Most plant failures we hear about are planting failures, not plant failures. Six things account for nearly all of them.
- Dig wide, not deep. The hole should be two to three times the width of the root ball and no deeper than the root ball itself. Roots spread sideways. Digging deep only guarantees the plant settles too low.
- Set the root flare at or slightly above grade. The flare is where the trunk widens into the roots. If it is buried, the plant will decline slowly over several years and nobody will ever connect the cause to the planting day.
- Do not over-amend the backfill. In sandy coastal soil it is tempting to fill the hole with rich potting mix. That creates a container in the ground: roots circle inside the comfortable pocket and never venture into native soil. Backfill with the soil you dug out, and put your organic matter on top as mulch instead.
- Deal with circling roots. Container-grown stock often has roots wrapping the pot wall. Tease them loose, or score the sides of the root ball vertically in three or four places with a knife. It feels brutal. It is the difference between a tree that establishes and one that girdles itself.
- Water deeply, not often. Two or three deep soakings a week for the first six weeks, then taper to weekly through winter dry spells. Deep and infrequent drives roots down.
- Skip the high-nitrogen fertilizer at planting. Nitrogen pushes top growth when you want root growth, and in fall it can push tender shoots straight into a freeze. A starter or root-focused product, or nothing at all until spring, is the better call.
Planting near the water: salt, wind and sand
Properties toward Swansboro, Sneads Ferry, Emerald Isle and the sound side deal with conditions that will quietly kill an inland plant list. Salt spray burns foliage, wind desiccates it, and sandy soil holds neither water nor nutrients for long.
Plants that hold up: wax myrtle, yaupon holly, live oak, eastern red cedar, juniper, oleander, muhly grass, rosemary, lantana and beach elder. Build the windward edge of the planting from the toughest of those, and the more tender material will live comfortably behind it. That layered approach works far better than trying to protect individual plants.
What is growing here right now
We propagate and grow about 95 percent of our plant material on our 42 acre property on Grants Creek Road, in sizes from one gallon up to 65 gallon. That matters more than it sounds: a shrub grown here has already lived through our summers, our soil and our humidity before you ever put it in the ground.
You are welcome to walk or drive the property and hand pick your own plants. Our retail shop carries the rest of the fall list: pine and wheat straw, soil and mulch, Espoma, Fox Farm, Fertilome and Hi-Yield products, grass seed, pottery, seasonal decor and garden tools. If you are looking for something specific, call ahead at 910.353.0326 and we will check availability before you make the drive.
If the project is bigger than a weekend, our landscape division handles design, installation, irrigation, drainage and seasonal color change-outs across Onslow, Carteret and Craven counties.
Frequently asked questions
Is it too late to plant trees and shrubs in November in coastal North Carolina?
No. November is still a good planting month in zones 8a and 8b, and plantings continue successfully into December as long as the soil is workable and not frozen. Roots keep growing whenever soil temperature stays above roughly 40 degrees, which happens often through our winters. The one requirement is that you keep watering during warm, dry stretches, because a plant that is dormant above ground is still working below it.
When should I plant pansies in Jacksonville, NC?
Mid-October onward, once soil temperatures drop below about 70 degrees. Pansies planted into warm September soil stretch, grow leggy and are much more likely to rot. Planted at the right time they bloom on and off from fall until May. Violas handle sharp cold snaps a little better than large-flowered pansies and recover faster after a hard freeze.
Can I grow tulips in coastal North Carolina?
Yes, but treat them as annuals. Our winters do not deliver enough chilling hours for tulips and hyacinths, so the bulbs need six to eight weeks in a refrigerator before planting in late November or December, kept away from ripening fruit. Daffodils, alliums and Spanish bluebells need no pre-chilling and will come back year after year, which makes them the better long-term investment here.
Should I overseed my centipede lawn with ryegrass in fall?
We advise against it. Ryegrass competes with centipede for light, water and nutrients precisely when centipede is coming out of dormancy in spring, and it is a common cause of thin, weakened centipede lawns in this area. Winter dormancy in centipede is normal and the lawn does better if it is left alone. Centipede should also not be fertilized in fall.
Should I fertilize new shrubs and trees planted in fall?
Skip high-nitrogen fertilizer at fall planting. Nitrogen pushes soft top growth at the moment you want the plant putting energy into roots, and new shoots forced out in October or November can be damaged by the first freeze. A starter or root-focused product at planting is fine, and a soil test will tell you what the site actually needs come spring.
What plants handle salt spray and coastal wind near Swansboro and Sneads Ferry?
Wax myrtle, yaupon holly, live oak, eastern red cedar, juniper, oleander, muhly grass, rosemary and lantana all tolerate salt and wind well. The most effective approach is layering: put the toughest species on the windward edge as a screen, then plant more tender material behind that protection rather than trying to shelter individual plants.
