Flowering Dogwood Care & Identification Guide
The magnificent Flowering Dogwood (Cornus florida) is a highly spectacular deciduous small tree native to Eastern North America, celebrated globally for its showy spring display of four petal-like white bracts. Each bract is identified by a highly distinct brownish-purple notched tip. It forms a dense, layered horizontal canopy. **Critical Warning: Its autumn red berries are toxic to dogs and cats.** It requires rich, acidic, well-drained loam and morning sun with afternoon shade.

11-Step Professional Care & Planting Guide
💧 【Watering & Moisture】 Water moderately. Keep soil consistently moist but never soggy. Deeply irrigate once a week in dry summers; avoid spraying water on the foliage.
☀️ 【Sunlight & Exposure】 Requires morning sun with dappled afternoon shade. Dislikes intense, direct midday heat, which scorches the leaves.
🪴 【Ideal Soil Mix】 Prefers deep, rich, organic, well-draining acidic soil. Blend 50% organic loam, 30% peat moss, and 20% perlite (pH 5.5-6.0).
🌡️ 【Temperature & Winter Care】 Cold-hardy (USDA Zone 5-9). Protect root zone with a thick layer of organic mulch. Dislikes dry, scorching wind.
✂ 【Pruning & Grooming】 Prune only in late winter to remove dead or crossing limbs. Maintain its natural, elegant layered horizontal branching pattern.
🧪 【Fertilization】 Apply a slow-release organic acidic fertilizer once in early spring. Mulch the drip line with composted leaf mold.
🏺 【Potting & Garden Planting】 Plant under larger shade trees. Dig a wide, shallow hole twice the root ball, backfill with acidic loam, and mulch deeply.
🌱 【Propagation】 Propagated by softwood cuttings in early summer, or by sowing seeds in autumn requiring 120 days of cold stratification.
🐛 【Common Pests】 Watch out for dogwood borers or scales. Treat manually with organic insecticidal soap or neem oil.
🦠 【Common Diseases】 Highly susceptible to Dogwood Anthracnose (a deadly fungus causing leaf spots and twig dieback). Keep foliage dry and prune infected twigs.
🎓 【Botanist Advice】 The Flowering Dogwood is an understory tree that loves acidic, organic mulch! Keep lawnmowers away, as trunk wounds provide easy entry for fatal anthracnose fungus.
Frequently Asked Questions
Q: Are those white petals the actual flowers?
A: No! The four large white showy structures are modified leaves called bracts. The actual true flowers are the tiny, greenish-yellow clusters nestled in the very center of the bracts.
Q: Are the bright red Dogwood berries toxic?
A: Yes! While wild birds eat them safely in autumn, the red berries are toxic to dogs, cats, and humans, causing mild to moderate stomach upset.
Q: How to tell Flowering Dogwood apart from Kousa Dogwood?
A: Flowering Dogwood blooms in early spring before leaves expand, and its bracts have distinct notched tips. Kousa Dogwood blooms later in summer after leaves are fully grown, and its bracts have sharply pointed tips.
Q: What is Dogwood Anthracnose?
A: It is a destructive fungal disease that causes leaf spots, cankers, and rapid twig dieback. Prevent it by planting in partial shade, keeping leaves dry, and avoiding bark wounds.
