Dogwood Tree Varieties
Flowering Dogwood
The flowering dogwood (Cornus florida) is the state tree of Virginia, Missouri, and North Carolina. It is a small deciduous tree that typically grows to 15-30 feet tall with a spread of 15-25 feet. The leaves are oval-shaped and 3-6 inches long. The flowers are small and white, and the fruit is a red drupe.
Kousa Dogwood
The kousa dogwood (Cornus kousa) is native to Asia but has been introduced to North America. It is similar in appearance to the flowering dogwood, but it typically grows to 20-40 feet tall with a spread of 20-30 feet. The leaves are oval-shaped and 4-8 inches long.
Pacific Dogwood

Growing Conditions For Dogwood Trees
Light & Temperature
These trees do best when they receive enough sunlight and warmth; typically, they need at least 8 hours of direct sunlight each day. Therefore, if planting dogwoods in your yard, be sure to place them in an area that receives plenty of sun.

Dogwood trees also thrive on slightly cooler temperatures - ideally, between 60-80°F (15-27°C). If you live in a part of the world with harsh summer climates and dry spells, providing adequate shade and mulching the soil can help the trees fight off this extreme heat.
Soil
Dogwood trees thrive in many types of soil, but for optimal growth, a soil with a neutral pH level is ideal. The best soils for Dogwoods are loamy and include enough organic matter to help the tree hold moisture and nutrients.

If the soil's pH is too high or low, the roots may not be able to access phosphorus and other essential minerals, resulting in stunted growth. Gardeners have found success in mulching around the base of their Dogwood trees which helps retain moisture and add additional nutrients in organically rich soils.
When planting a new Dogwood tree, it may be beneficial to take some soil samples to test for pH levels as well as nutrient levels so you can achieve an optimal growing environment.
Water
Dogwood trees need 2-3 inch depths of water every week during their first year in the ground, and a consistent 1-2 inches weekly during their second year. However, it's important to not over or under water this tree; by supplying too much water or too little, you risk damaging the roots and inhibiting growth.
Nutrients & Fertilizer
To ensure your Dogwood tree has optimal growing conditions, adequate nutrients and fertilizer are important. A comprehensive blend of nutrients should contain all the necessary primary, secondary and micronutrients.
When choosing a fertilizer, opt for one with an NPK ratio that matches the needs of Dogwoods such as 10-10-10 or 12-4-8. Fertilizers need to be applied at least twice annually - once during spring season when blooming begins and then again in midsummer. It’s also very important to remember not to over fertilize as it could cause more harm than good.
How To Plant & Grow A Dogwood Tree
Planting a dogwood tree can be an easy and enjoyable process if done correctly. Follow these steps to plant and begin growing your very own Dogwood Tree:
- Choose a location. Dogwoods do best in full sun to partial shade and well-drained soil. Avoid planting dogwoods in low-lying areas that stay wet for long periods of time.
- Prepare the planting site. Use a shovel or tiller to loosen the soil in the planting area and remove any weeds or other debris.
- Dig a hole. The hole should be twice as wide as the tree’s root ball and just deep enough so that the tree’s roots are covered with soil.
- Place the tree in the hole. Carefully remove the tree from its container or burlap wrapping and place it in the hole so that the roots are spread out evenly.
- Backfill the hole with soil. Use the removed soil to fill in around the tree, gently tamping it down as you go. Water the tree deeply to settle the soil and help promote root growth.
Dogwood Tree Care & Maintenance
Caring for a dogwood tree is not difficult, but it does require knowledge of the best practices and maintenance. Regular pruning is essential in maintaining the health and size of the tree. This can be done during summer to help assure the shape and structure of the tree.

Proper irrigation is also necessary as this species tends to be prone to drought stress; both overwatering and underwatering can cause damage to the root system, so it's important to find a balance.
Additionally, fertilizer should be applied in early spring combined with regular mulching around the base of the trunk in order to promote healthy growth and deter weeds. Dogwoods are low maintenance trees overall, but with careful attention to their care through these basic steps, you can enjoy their colorful flowers for years to come!
Common Dogwood Tree Pests & Disease
Pests
Though these trees bring an abundance of charm to the garden, they can sometimes be vulnerable to certain pests. Certain species of beetles, caterpillars, mites, and aphids all pose a threat to Dogwood tree growth and health.
It's important to keep an eye out for these pests in order to protect your yard's beloved Dogwood tree. Removing affected plants from the area may help reduce the level of infestation and treating the tree with pesticide or insect spray may also be necessary on occasion. Prevention is key when it comes to keeping these lovely trees strong and healthy!
Disease
The Dogwood Tree is susceptible to a few common diseases. Anthracnose is a fungal disease that causes leaf spotting and dieback of the shoots and twigs, which can eventually kill the tree if left unchecked. Canker can occur at any time of the year, resulting in lesions that girdle branches and inhibits transport of sap, leading to decreased vigor and potentially death.

Powdery mildew is another issue that can cause yellowing leaves; while not usually fatal on its own, it increases stress on the tree which could lead to disease or death. Fortunately with proper maintenance such as building up soil content around the base and pruning dead branches, these issues are manageable.
Conclusion
Dogwood trees are majestic plants that grow in many regions all over the world. They can have year-round colorful blooms, vibrant foliage and distinct bark that adds to any landscape. With proper care, Dogwood Trees can thrive for long periods of time.
When planting a Dogwood Tree, it's important to pick a spot with full sun or light shade, as they don't necessarily need direct sunlight to survive but tend to do much better with some filtered rays. Most varieties require well-drained soil and are not very tolerant of drought so regular watering is required.
To keep the tree healthy and thriving, fertilize annually by adding organic material like compost around the root structure to nourish them while they grow. All in all, with adequate care and attention, the Dogwood Tree will add beauty to your landscape for years to come!
