Ogeechee Tupelo is known for the red fruits that have been used as a substitute for limes because of their pleasant flavor. The lustrous dark green leaves are acute to obtuse and lightly covered with short hairs. This tree species was introduced in 1806.

How-to : Fertilization for Established Plants
Established plants can benefit from fertilization. Take a visual inventory of your landscape. Trees need to be fertilized every few years. Shrubs and other plants in the landscape can be fertilized yearly. A soil test can determine existing nutrient levels in the soil. If one or more nutrients is low, a specific instead of an all-purpose fertilizer may be required. Fertilizers that are high in N, nitrogen, will promote green leafy growth. Excess nitrogen in the soil can cause excessive vegetative growth on plants at the expense of flower bud development.
It is best to avoid fertilizing late in the growing season. Applications made at that time can force lush, vegetative growth that will not have a chance to harden off before the onset of cold weather.
Conditions : Full to Partial Sun
Full sunlight is needed for many plants to assume their full potential. Many of these plants will do fine with a little less sunlight, although they may not flower as heavily or their foliage as vibrant. Areas on the southern and western sides of buildings usually are the sunniest. The only exception is when houses or buildings are so close together, shadows are cast from neighboring properties. Full sun usually means 6 or more hours of direct unobstructed sunlight on a sunny day. Partial sun receives less than 6 hours of sun, but more than 3 hours. Plants able to take full sun in some climates may only be able to tolerate part sun in other climates. Know the culture of the plant before you buy and plant it!
Problems : Creating a Water Ring
A water ring, sometimes called a water well, is a mound of compacted soil that
is built around the circumference of a planting hole once a plant has been
installed. The water ring helps to direct water to the outer edges of a
planting hole, encouraging new roots to grow outward, in search of moisture.
The height of the mound of soil will vary from a couple of inches for 3 gallon
shrubs, to almost a foot for balled and burlapped trees, especially those
planted on a slope. Mulch over the ring will help to further conserve moisture
and prevent deterioration of the ring itself. Once a plant is established, the water ring may be leveled, but you should continue to mulch beneath the plant.
Conditions : Moist and Well Drained
Moist and well drained means exactly what it sounds like. Soil is moist without being soggy because the texture of the soil allows excess moisture to drain away. Most plants like about 1 inch of water per week. Amending your soil with compost will help improve texture and water holding or draining capacity. A 3 inch layer of mulch will help to maintain soil moisture and studies have shown that mulched plants grow faster than non-mulched plants.
Conditions : Normal Watering for Outdoor Plants
Normal watering means that soil should be kept evenly moist and watered regularly, as conditions require. Most plants like 1 inch of water a week during the growing season, but take care not to over water. The first two years after a plant is installed, regular watering is important for establishment. The first year is critical. It is better to water once a week and water deeply, than to water frequently for a few minutes.
How-to : Staking Trees
Staking is done differently depending on the size and flexibility of the
tree, and the windiness of the planting site. Generally only trees that are planted in windy, exposed locations need to be staked. For most trees, a low stake is
preferred, to let the tree move naturally. For windy areas or flexible trees,
use a high stake. For trees more than 12 feet tall, use two low stakes on
opposite sides of the tree or several guy ropes. The ties used need to
accommodate growth and not cause bark damage with friction. Buckle-and-spacer
ties can be found at garden centers, they are expandable and have a protective
spacer. Ties without spacers should be formed into a figure eight to create
padding. Latest studies have shown that when staking a tree, provide enough
leeway so that the tree can move back and forth in the wind. Stronger roots will
develop this way. If the tree can not move back and forth, these important roots
will not develop and the tree might fall over during a storm, once stakes are removed. When planting a tree, stake at the time of planting if staking is a necessity.
How-to : Planting a Tree
Dig out an area for the tree that is about 3 or 4 times the diameter of the container or rootball
and the same depth as the container or rootball. Use a pitchfork or shovel to scarify the sides of the
If container-grown, lay the tree on its side and remove the container. Loosen
the roots around the edges without breaking up the root ball too much. Position tree in center of hole so that the best side faces forward. You are ready to begin filling in with soil.
If planting a balled and burlaped tree, position it in hole so that the best side faces forward. Untie or remove nails from burlap at top of ball and pull burlap back, so it does not stick
out of hole when soil is replaced. Synthetic burlap should be removed as it will not decompose like natural burlap. Larger trees often come in
wire baskets. Plant as you would a b&b plant, but cut as much of the wire away
as possible without actually removing the basket. Chances are, you would do more
damage to the rootball by removing the basket.
Simply cut away wires to leave several large openings for roots.
Fill both holes with soil the same way. Never amend with less than half original soil.
Recent studies show that if your soil is loose enough, you are better off adding little or no soil amendments.
Create a water ring around the outer edge of the hole. Not only will this
conseve water, but will direct moisture to perimeter roots, encouraging
outer growth. Once tree is established, water ring may be leveled. Studies show that mulched trees grow faster than those unmulched,
so add a 3"" layer of pinestraw, compost, or pulverized bark over backfilled
area. Remove any damaged limbs.
Pest : Caterpillars
Caterpillars are the immature form of moths and butterflies. They are voracious feeders attacking a wide variety of plants. They can be highly destructive and are characterized as leaf feeders, stem borers, leaf rollers, cutworms and tent-formers.
Prevention and Control: keep weeds down, scout individual plants and remove caterpillars, apply labeled insecticides such as soaps and oils, take advantage of natural enemies such as parasitic wasps in the garden and use Bacillus thuringiensis (biological warfare) for some caterpillar species.
Fungi : Leaf Spots
Leaf spots are caused by fungi or bacteria. Brown or black spots and patches may be either ragged or circular, with a water soaked or yellow-edged appearance. Insects, rain, dirty garden tools, or even people can help its spread.
Prevention and Control: Remove infected leaves when the plant is dry. Leaves that collect around the base of the plant should be raked up and disposed of. Avoid overhead irrigation if possible; water should be directed at soil level. For fungal leaf spots, use a recommended fungicide according to label directions.
Pest : Leaf Miners
Leaf Miner is actually a term that applies to various larvae (of moths, beetles, and flies) that tunnel between upper and lower leaf surfaces, leaving a distinctive, squiggly pattern. A female adult can lay several hundred eggs inside the leaf which hatch and give rise to miners. Leaf miners attack ornamentals and vegetables.
Prevention and Control: Keep weeds down and scout individual plants for tell-tale squiggles. Pick and destroy these leaves and take advantage of natural enemies such as parasitic wasps. Know the Growing Degree Days (GDD)* for your area to target insecticide sprays when most beneficial for controlling the specific leaf miner. Seek a professional recommendation and follow all label procedures to a tee. *GDD numbers should be available from your local Cooperative Extension office.
Glossary : U. S. Natives
Native plants require lower maintenance and usually have less pest problems. They are key components in the xeriphytic landscape and backyard wildlife habitat. Select your region and the search will look for all plants in the database that are native to your area.
