By Joanne K., Pitt County EMGV Coleus displays in many home and public container gardens around the area have been spectacular this year. Perhaps you have a favorite coleus or another summer annual that you don't want to lose when the frost comes. Coleus Green (Coleus scutellarioides) in late summer. Photo by Joanne K. As summer winds down, many annuals have luxuriant growth from which cuttings can be taken to propagate over the winter to enjoy in your garden next spring. Propagating cuttings is a fun way to extend your gardening season. Following are two easy propagation methods using stem cuttings.
Place the planter in a properly lit place for the type of plant you have. Use a 10-10-10 fertilizer when needed according to package directions.

By Joanne K., Pitt County EMGV Eastern NC is definitely in the dog days of summer now, with the heat index soaring above 100 and rain coming sporadically. Containers plants are particularly vulnerable to this twin whammy of hot, dry conditions, as the containers tend to dry out quickly. Pitt County Master Gardeners were asked to share photos of some of their favorite container gardens that have held up well this summer despite unfavorable growing weather. Below are their containers, along with the plants that have beat the heat!

The eastern NC climate allows for three-season gardening, and the cooler fall temperatures are ideal for such crops as lettuces, onions, broccoli, collards, and cabbage. Fall planting can be done between mid-August to mid-September. Start by getting a soil test, which is free between April 1 and the end of November. Soil test boxes and forms are available at the Pitt County Agricultural Center lobby and the NC Cooperative Extension office at 403 Government Circle, Greenville, NC 27834. Soil samples are sent to the NC Department of Agriculture and Consumer Services lab in Raleigh, and the turnaround time is about two weeks. As the summer crops start to decline, pull out the spent vegetation and weeds to make room for fall crops. Don't turn them under in the garden, however, as the summer build-up of insects and diseases can still linger in the soil in the warm fall temperatures, threatening your new plantings.
NC Cooperative Extension offers an "Eastern North Carolina Planting Calendar for Annual Vegetables, Fruits, and Herbs", which includes information on planting dates, days to harvest, and whether to plant seeds or transplants. You can request a copy from Pitt County Extension Master Gardeners at 252-902-1705 or access the guide online. For more information on vegetable gardening, go to the Extension Gardener handbook.
Plant now and enjoy your own fresh vegetables through the fall and early winter! Photos: Transplants - Lucy B., CC BY 2.0 Curly leaf kale - Lucy B., CC BY 2.0 Swiss chard - Kathleen M., CC BY 2.0 By Joanne K., Pitt County EMGV Gorgeous hydrangea blooms in hues of pink, purple, blue, white, and green are the current stars of eastern NC gardens. These shrubs have really rebounded this year with robust blooms after the disappointing hydrangea displays in 2022 due to an exceptionally dry year. But now as the blooms start to fade, gardeners are faced with the question of when to prune their plants. Pruning is needed to remove old blooms, control size and shape, remove diseased/damaged stems and leaves, or rejuvenate an overgrown plant. The rule of thumb for hydrangeas is if they bloom on old wood, cut back immediately after blooming, removing only about 1/3 of the plant. If they bloom on new wood, prune after flowering or in winter. The challenge is to determine what kind of hydrangea you have.
Hydrangea blooms are perfect for dry, indoor winter arrangements. An easy way to dry the blooms is to place the mature flowers with all of the leaves stripped from the stem in a container with a couple of inches of water. Keep the container out of direct sunlight.
In a couple of weeks, the process will be complete. The blooms won't absorb the water, and the dried color will be more vibrant than ones allowed to dry on the stem. Google "how to dry hydrangeas" for more information. With careful plant selection, your garden can feature a beautiful continuous hydrangea display from late spring into the fall and winter!

Story by Joanne K., Pitt County Arboretum Extension Master Gardener Volunteer What to do when you want to add more color and excitement to your garden, but there's just no space to squeeze in one more plant? That's when the savvy gardener turns to container gardening to create new gardens every season and every year without the heavy lifting required to start a new planting bed. At the Pitt County Arboretum, the Master Garden container team changes out the pots each season showcasing the variety of plants suitable for planters. Annuals, perennials, shrubs, trees, grasses, succulents, herbs, and vegetables are all fair game for container planting. The accompanying pictures show three of the Arboretum containers planted for summer for part sun, full sun, and shade. Master Gardener Teresa S. shares the following tips for successful container gardening.
When shopping at your favorite nursery, start planning your next container garden creation with these tips in mind!

The following suggestions are from the University of California, Davis. Certainly envisioning a simpler garden is one step to take. Instead of planting annual beds, replace them with perennials and shrubs that, once established, will require minimal care. Select shrubs that require little or no pruning. Plant tough perennials that can withstand our summer heat and occasional droughts without missing a beat.
Don't be afraid to ask for help from younger family members, or perhaps look into getting some paid help for the heavier tasks.
More suggestions for adapting your garden can be found at UC Davis at https://ucanr.edu/sites/cetrinityucdavisedu/files/280231.pdf and at https://cetrinity.ucanr.edu/files/280232.pdf. Once you start implementing these suggestions into your gardening routine, you'll never look back. And your body will thank you! Story and photos by Joanne K., Pitt County Arboretum Extension Master Gardener Volunteer Although our grass does not actively grow in winter and early spring, the weeds certainly do! They seem to pop up everywhere in the lawn, causing headaches for grass lovers. Weeds are defined as plants growing where you don't want them. Most of the same weed species will return in the same areas every year. Weeds compete with the grass for light, water, nutrients, and space.
These include calculating the square footage, measuring the herbicide amount accordingly, and correctly calibrating the spreader.
An excellent resource is the turf grass file at NC State University: https://www.turffiles.ncsu.edu/weeds-in-turf/ The NC State University website describes the various weeds that occur at different times of the year and includes pictures for identification. It describes cultural and chemical controls listing the pre- and post-emergent herbicides that can be used, along with explanations on their usage. Lawn maintenance calendars can be requested from the Pitt County Extension Master Gardener Volunteers by calling the Info Line at 252-902-1709. By Joanne K., Pitt County EMGV
But if you can't resist the allure of an early harvest and decide you must transplant your tomatoes now, be prepared to cover them if a frost warning is issued. It’s best to buy and plant your tomato and pepper transplants after March 30, Eastern NC's last average frost date. If you want to grow your own pepper and tomato transplants, start the seeds 6 to 8 weeks before their recommended transplant date, which is April 15 for both plants. While all of these vegetables and herbs can be planted directly in the ground, you may prefer to grow them in a container garden if you have limited space or prefer the ease of maintaining a container garden. When planting in pots, be sure to use potting soil rather than garden soil, which will compact and drain poorly. Potting soil also reduces the chances of weeds and soil-borne diseases. Most potting soils incorporate fertilizers, which will get your plants or seeds off to a great start.

But a word of caution: be careful to prune at the right time. Otherwise, you will lose or reduce that year's blossoms.
healthier in the long run. Shrubs responding well to such pruning include azaleas (Rhododendron spp.), butterfly bush (Buddleia davidii), forsythia (Forsythia spp.), hollies (Ilex spp.), mock orange (Pittosporum tobira), spirea (Spirea spp.), and weigela (Weigela florida). There is no need to treat pruning cuts with sealers, as doing so may slow healing. Avoid pruning after July 4 because the new growth may not mature before cold weather sets in and this could damage the plant. The exception is dead, diseased, damaged, or crossing limbs, which can be removed at any time. Pruning shrubs is both an art and a science. Your shrubs will thank you when you do it right by following the above practices at the right time. All photos: J. Kollar
1. Abelia x grandiflora 'Kaleidoscope 2. Chaenomeles Flowering Quince 3. Lagerstroemia indica Crape Myrtle by Joanne K., Pitt County Extension Master Gardener Volunteer During these dreary winter days, gardeners yearn for some sign of color to bring indoors to promise that spring is on its way. However, the garden has little to offer in the way of colorful cut flowers for indoor bouquets in January and February. But there is a way to bring color inside by forcing the stems of winter – and spring-flowering trees and shrubs to bloom.
For the best results, look for branches with many enlarged buds that are starting to show some color. The closer the buds are to actual bloom time, the more successful the flowering will be.
Successful forcing requires both warm indoor temperatures and a good uptake of water into the stems. Before placing the stems in a vase with warm water, remove any buds, twigs, or leaves that will be under water.
If your cuttings have not opened after about four weeks, they were cut too early. Try again with new cuttings.
Through trial and error, you'll discover the flowering trees and shrubs that work best for you and when is the best time to bring them indoors. While waiting for the beginning of the spring planting season, bringing some woody branches inside to flower is a fun way to enjoy some winter gardening. |
