A wide range of sap-sucking insects love snapdragons. Aphids, mites, mealybugs, and whiteflies are common sights in stands of snapdragons. These pests can cause disfigured leaves and flowers if they feed on buds; otherwise, you may notice stippling on leaves or a general lack of Read more
The University of Florida provides a lengthy list of insects and pests that are problematic for snapdragons. These include mites (e.g., spider, cyclamen), beet armyworms, the American serpentine leafminer, corn earworm, pill bugs, slugs, snails, aphids, thrips and tobacco budworms.
When your plant can't soak up enough water from the environment, it will start to show. Wilting is the first sign of a lack of water in plant cells, due to a lack of turgor. Water snapdragons in beds deeply when the top two inches Read more
Snapdragons can tolerate light frost. Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at Read more
Snapdragons prefer a medium watering schedule, which means watering about once a week during periods of low rainfall. Soak the soil in the garden bed until the top 1 inch is saturated. Check the soil more frequently during hot, dry weather. If the top inch Read more
Antirrhinums are cheerful annual plants, guaranteed to brighten up borders and containers. Commonly known as snapdragons, these are easy-to-grow, old-fashioned cottage garden plants, beloved by children and bees.
Tall, short or even dwarf, upright or trailing, in primary colors and shades in between, the snapdragon (Antirrhinum majus) is an old garden favorite. Although many pests are attracted to snapdragons, if the plant is healthy it will survive an infestation.
Snapdragons are tender perennials that are hardy in USDA zones 7-11. But snapdragons prefer cooler temperatures and are at their best when nighttime temperatures are in the low 40s F and daytime temperatures in the low 70s F.
Snapdragons propagate either by seed or cuttings. They are considered a “self-seeding” annual. When left alone, seeds from spent flowers will fall to the ground, survive the winter (up to -30 degrees!), and come back the next year as new plants.
Many gardeners don't realize snapdragons are so cold hardy. Once established in the bed and hardened off, they can withstand sub-freezing temperatures. Make sure they stay well watered during cold spells and add a layer of pine straw mulch, and they can last for quite Read more
Since snapdragon seeds are so small, you will not need to bury them in holes in the soil. Instead, sow seeds by sprinkling them across the soil surface, and then either sprinkle a light layer of soil over the top or simply press down to Read more
The American Society of Prevention of Cruelty to Animals says colorful snapdragons (Antirrhinum majus) are nontoxic to dogs, cats and horses. Researchers at the University of California include snapdragons on their list of safe plants for adults and children.
These are tiny bugs of tan, gray or green; they tend to congregate in masses on buds, the undersides of leaves and along stems where they suck the nutrients from the snapdragon. What they can't process, they excrete as a sticky substance known as honeydew.
Antirrhinum rust is the most serious disease of antirrhinums (snapdragons). It is a fungal disease that causes dark brown spots on the undersides of leaves. Severely affected leaves shrivel and may die.
Bright, boisterous snapdragons are another safe flower for dogs. Not only do they add some serious charm to homes and gardens, they're also non-toxic for your pet.
Once established, snapdragon will need approximately 1 inch of water per week in times of no rainfall. Water near the crown of the plant and avoid overhead watering to keep your snapdragon healthy. Once established, let the top inch of soil dry fully before watering.
Snapdragons can do well indoors. However, they need six to eight hours of direct sunlight daily to grow and produce the most abundant flowers. Even the sunniest indoor location is not likely to receive this much sunlight, especially during the winter.
Snapdragons The snapdragon is a unique flower, in scent, shape, and color. However, they do see yellow and blue, which makes the color of snapdragons attractive to bees as well. Its bell shape also gives bees easy access to its sweetness.
Deadheading will help keep your snapdragons blooming throughout the summer. Remove the faded flowers just below the flower stem and above a set of healthy leaves. This will keep the new blooms coming. If the plant becomes leggy (long stems and few leaves) prune back Read more
Growing Tips Snapdragons bloom best in well-drained, moist soil, in cool late-spring or early-summer temperatures. They can tolerate light shade but bloom much better in full sun.
Snapdragons need adequate watering. Keep seedlings moist for the first few weeks. Once established, snapdragon will need approximately 1 inch of water per week in times of no rainfall. Water near the crown of the plant and avoid overhead watering to keep your snapdragon healthy.
Diseases. Downy mildew, a fungal disease, leads to the yellowing of leaves on snapdragons. Caused by the pathogen Peronospora antirrhini, downy mildew primarily occurs during moist, cool weather and may develop quite quickly. A disease referred to as snapdragon rust is also responsible for leaf Read more
Tall varieties of snapdragons may require staking to remain upright. Water near the crown of the plant and avoid overhead watering to keep your snapdragon healthy. Once established, let the soil dry about an inch deep before watering. Snapdragon care includes the removal of spent Read more
Cut the plants back to the ground at the end of the growing period when the foliage turns brown, usually in early fall for cooler climates and late spring to early summer in warmer climates.
Fertilize snapdragons as soon as they start producing flowers. Stake taller varieties so they don't fall over under the weight of those stalks of flowers. Prune spent blooms during the spring to keep the snapdragons blooming. Cut them back in the dog days of summer Read more
Caring for Snapdragon Flowers Humidity: Average room (around 40% relative humidity). If indoor air is dry, try one of these easy ways to increase humidity for your snapdragons. Temperature: Snapdragons thrive in cool to moderate temperatures (60-75°F/16-24°C).

Although snapdragons are tolerant of cold weather, they may not do so well in very hot climates. When summer temperatures soar, they are likely to wilt and decline, and their flowering performance suffers.
Soil. Snapdragons like a neutral soil pH between 6.2 and 7.0, rich in nutrients and well-draining. As short-lived plants, they are not heavy feeders, but adding organic matter will help keep them healthy and blooming.
Soil Conditions Snapdragons thrive best in soil that s well draining and moist. If the snapdragon planting site has poor soil conditions, such as excessive sand, gardeners can enhance the soil structure by mixing 4 inches of well-aged compost into the top 6 to 8 Read more
Snapdragons are long-blooming flowers that continue to produce new blooms for two months or more from early- to midsummer on. They may stop blooming in hot weather, but typically resume blooming when it cools down, if you cut them back.
Anthracnose (fungus – Colletotrichum antirrhini): Large, light colored spots occur on leaves and stems. Entire leaves may be killed and often the whole plant dies from stem girdling. Spore bearing pustules appear as minute black pimples in the spots.
Snapdragons don't need fertilization at the planting date. Instead, gardeners should administer the first application of fertilizer when the plants first start producing flowers. Use any standard all-purpose fertilizer, such as a 10-10-10 product, at a rate of three pounds for every 100 square feet Read more
