You can also buy it by the linear foot for use in landscaping.

Price Range

Container grown plants range from about $15 to $75 each, depending on size and quality. Linear foot prices range from $10 to $30.

Repotting

Repot only as needed, preferably during the spring. If you choose to repot a mature plant, do not do it every year. Established, well-sized plants can remain in the same container for 5 or more years.

Light & Moisture

Although southern arrowwood grows in a variety of soil types, it prefers sandy loam that is moist but well-draining. It can grow in full sun to partial shade (or full shade if the plant is mature). This shrub tolerates dry conditions but does not thrive in them. Water regularly for best results. Overwatering can kill it, so err on the side of less rather than more.

Fertilizing

Apply a balanced slow-release fertilizer in the spring. If you are using a time-release granule, scatter it around the roots but do not place it too close to them. Too much fertilizer will cause a lot of leaf growth at the expense of flower production.

Temperature & Humidity

Optimal temperature range for southern arrowwood cultivation is 60 to 90 degrees Fahrenheit. If the temperature drops below 50, the plant will enter a state of semi-hibernation and cease growing until conditions improve. Higher temperatures (above 90 degrees) will cause the foliage to develop aBurning leaves and leaf edges will developstressed appearance and may turn brown and die.

Buying Tips

When buying southern arrowwood, look for a glossy green, smooth-textured leaves. The leaf stems should be yellowish or light green. The yellowish stems have been found to produce the best foliage color and growth. If the plant has berries, they should be a vibrant red without any dimness of color in them at all, and the shrub itself should not have any dead branches. It is also important to make sure that the container you buy it in has drainage holes – otherwise, it will simply sit in a pool of water and drown.

If you cannot easily discern that the container has holes in it, do not buy the plant!

Flowering & Fruiting

Southern arrowwood will begin to flower when it is between 1 and 3 years old. The shrub will send up flower stalks (called scapes) that are about 3 feet tall. These stalks are generally unbranched and may have between 1 and 4 terminal flowers on them. These flowers can be up to 2.5 inches across and have a delightful fragrance.

They are primarily white but have up to 15 wide, flat petals that can be a light pink color and have darker pink veining. Each flower also has a prominent corona. The blooming period generally occurs from early to mid spring and lasts about 1 to 2 months. Flowering is followed by the production of small berries that start out green and eventually ripen to a dark red.

Caring For Your Shrubs

Southern Arrowwood Shrub Care – How To Grow Southern Arrowwood Plants - Picture

Once your plants have become established in the landscape, little maintenance is required other than watering. However, there are a few pests and diseases that can develop that you may need to treat.

Pests

As far as pests go, southern arrowwood is vulnerable to the same ones that affect azaleas: leaf-eating insects and fungal diseases.

Leaf-Eating Insects. Southern arrowwood is prone to infestation by the azalea leaf miner, the azalea petioid borer and azalea lace bug. These insects all attack the foliage and make leaves look very tattered. There is no way to prevent these pests, but there are chemical controls that can be used if necessary. Buy these at a garden center or nursery and follow all label instructions.

Fungal Diseases. Too much water is a common cause of fungal disease and can affect the health of your southern arrowwood plants. If you have over-watered, the foliage will likely develop brown spots or entire areas that have turned yellow and wilted. Remove all affected leaves as soon as possible to reduce the spread of the disease and limit the damage.

Diseases

Southern arrowwood is prone to a few diseases that can cause serious problems if not treated. The most common are petiole and collar rot.

Petiole and Collar Rot. This disease is caused by the excessive watering of moisture-laden soil around the base of the plant. If this persists, the roots can no longer take up nourishment and the base of the plant begins to rot. This begins with the oldest stems, working its way outwards. Eventually, the entire shrub can be involved and killed.

This is a very common disease of many types of plants, especially those in the heather family such as azaleas. It is important to know the signs of this disease and to act at the first indication. If caught in time, a fungicide can be used to treat the plant.

Additional Pest and Disease Management. You can help prevent many pest and disease problems by following good cultural practices. First of all, proper planting site is important. Southern arrowwood plants should be planted in an area that has full sun to partial shade. They should be on the site for at least two years before you expect to have bloom and berry production.

This will give southern arrowwood time to become acclimated to your particular environment and lessen the chances of problems. Additionally, observe the site and remove other shrubs or trees that may compete for moisture, nutrients and sunlight.

Care should be taken not to over-water. Soil should be well-draining. Do not add lawn fertilizer, as this may cause excess moisture when it is broken down. Use only slow-release fertilizers placed in the soil at planting time. Also, do not allow lawn grass to grow up and surround the southern arrowwood plants.

When watering, water evenly throughout the entire plant and avoid putting any water on the plant just before a heavy rain is expected. This is very important, especially during the first couple years as the plants are getting established.
