Growing Datura (Ummetha) From Seeds, Cuttings

Introduction to growing Datura (Ummatta)

Datura is also called as devil’s trumpet, makes a striking container plant, and is used in borders and as a specimen plant. The common name of the Datura plant is thorn apple, angel’s trumpet, stinkweed, and Jamestown weed. Datura is belonging to the family of Solanaceae. They are commonly known as jimsonweeds or thornapples but are also known as devil’s trumpets. A large plant typically characterized by grayish-green leaves, pale and white, trumpet-shaped flowers that bloom in the night. Grow Datura in a container or garden bed that gets strong sunlight. Datura plants like rich, well-draining, garden soil and require plenty of water. Datura does not need deadheading unless you wish to delay the production of their decorative seed pods and prolong blooming.

Differences between Datura and Brugmansia

The plant is not to be confused with Datura, which also called Devil’s Trumpet. Datura flowers look similar to Brugmansia and both belong to the botanical family Solanaceae.

While the two flowers look similar, the flowers of Datura are erect, and Brugmansia is pendulous. Brugmansia is also woodier rather than shrub-like. Brugmansia can grow up to ten feet in height, while Datura generally tops out at four feet tall.

Soil and light requirement for growing Datura

Datura does best in full or close to full sun. Datura is a truly tropical species that does not take kindly to colder temperatures and cold drafts are likely to result in leaf drop, and frost will kill it. Grow Datura in full sun and well-drained soil. It is drought tolerant once established and thrives in almost any type of soil, but the Datura plants are most impressive when grown in humus-rich loam with regular moisture. Well-drained, Humus-rich, and calcareous soil is required for growing Datura. Though, it tolerates a variety of soil types.

Suitable site for growing Datura

Suitable growing sites receive full, all-day sunlight for best flowering, even though Datura can tolerate some afternoon shade in hot climates. Datura growing in most types of soil if it receives consistent moisture. Working a two-inch layer of compost into the soil before you plant, will improve moisture retention and site fertility. A growing site is not prone to standing water and is naturally fertile and rich in organic matter results in ample flowers and healthiest growth.

Datura propagation

Datura propagates with seed pods or side shoot cuttings. And most of the gardeners normally buy the Datura as a plant and transfer them into their garden. The Datura seeds grow aggressively, repot each spring season into a larger pot with similar soil types. A full-grown Datura can reach heights of about 8 feet tall, making it difficult to manage to repot.  Scrape off the top 1 or 2 inches of soil and replace with fresh soil. You can also add time-release fertilizer at this point.

Sowing Datura seeds

Datura seeds are sown indoors in individual pots 2 to 3 months before planting them outdoors. Any type of potting soil or seed starting medium will do, but using a soilless mix will help prevent fungal diseases like damping off. Keeping the air around the seeds very moist until the germinate will result in higher seed germination rates. Placing the pots in a tray with a clear plastic cover or in a clear plastic bag and then carefully closing it tightly will increase humidity. Open the bag or remove the cover as soon as the Datura seedlings germinate. The seeds germinate fastest at temperatures between 21 to 24°C. Datura seed germination can take anywhere from 1 to 6 weeks.

Datura starting from seeds

Datura seeds germinate within 14 to 30 days when temperatures are between 15 to 18 °C. Although germination is better assured by sowing the Datura seeds indoors, you can plant it directly in the garden bed outside after all spring frost danger is past. Sow the Datura seeds half-inch to one inch deep and space them four feet apart to allow room for the plants to reach their mature size. The seeds germinate in moist soil, so water as needed so the top six inches of soil remains moist but avoid overwatering and waterlogged soil.

After collecting the Datura seedlings from brown seed pods, scarify seeds by carefully scraping the seeds with a knife. This will help the germination process of Datura. Later, soak the seeds in a thermos with warm water for 24 hours.

Arrange the Datura seeds in a tray with a thin vermiculite or compost layer and also arrange enough light, heat while keeping them moist but not soggy. Check the seeds daily for 3 to 8 weeks and see if they have germinated. Sow Datura seeds 1/4 inch deep indoors around mid-March. Transplant seedlings to the garden about 4 feet apart.

Planting Datura seeds

Step 1) The Datura seed pods of the plant start green but will split when ripe and release flat, tan-to-black, kidney-shaped seeds that will not germinate before the pod ripens, but when they reach that point, they will remain viable for a few years. In some cases, Datura plants can become invasive if the seeds spread in areas where the plant is not native.

Step 2) Datura plants are easy to grow from seed. Datura requires full sun and rich fertile earth that drains well. Sow Datura seeds directly outside into a prepared bed in fall in warmer climates and early spring after all danger of frost has passed in cooler climates. You can grow trumpet flowers outside or inside in a pot or simply spread Datura seed with a light coat of sand outside in a sunny location. The little plants will beat your expectations with their speedy growth and minimum maintenance.

Step 3) To keep Datura seeds for storage and future planting, the seeds must be dried, ideally on paper towels or other absorbent materials. They must be stored in an airtight container in a cool, dark area. It is best to sow seeds 1/8-inch deep in fertile, well-drained soil and the ideal temperatures for seeding plants are 15 to 18°C, and the plants enjoy the sun to part shade and ample moisture. Datura plants can also be grown from cuttings of mature individuals. Many Datura species’ seeds germinate in late spring or early summer and often grow in places such as roadsides, orchards, ditches, pastures, and unmanaged areas, etc.

Water requirement for growing Datura

Regularly watering them during the growing season to keep the soil moist at all times, but not soaking. During the winter, reduce watering slightly, but never let the soil completely dry out and they are occasionally deciduous in the winter.

Datura propagation from root cuttings

Step 1) Dig the soil near established angel’s trumpet plants in early spring, as carefully as an archaeologist would until you uncover some thick roots. Cut a few sections of those roots that are about 3 to 4 inches long.

Step 2) Remaining roots to be covering it again with soil to preserve the existing angel’s trumpet plants. Bury the cut sections at the same depth they had been growing but should be placed in a new location, to make additional plants.

Step 3) Keep the soil in that area damp until the cuttings begin to sprout.

Caring for the Datura plant

• Planting Datura needs full sun coupled with moist, rich, well-drained soil. As a tropical species, they thrive in the warmer months and don’t take kindly to frost and winter months. If left by them in winter, every Datura leaf will drop and the plant most likely dies.
• Datura plants will get benefit from extra water during the growing season; the soil should stay moist. In the winter months, drastically decrease watering but not to the point the soil completely dries out. In winter season the Datura may go deciduous. Pot Datura seed in a light well-drained soil. A weak liquid plant food could encourage blooming.
• The Datura can tolerate poor soil conditions and also survive even a little drought. In general, it may become leggy and not produce many flowers. They resist the majority of pests.
• Datura grows quickly and needs plenty of room. Datura needs plenty of room and will quickly grow to fill an area of several feet once the weather gets hot so place them accordingly. They may be grown from seed sown outdoors after the last frost or started indoors about  6-8 weeks before the average date of the last frost and planted outdoors after all threat of frost has passed.
• Datura plants need full sun, regular watering, and fertile soil. Datura gets droopy and cranky if they do not get adequate moisture. During winter seasons they can sustain themselves in most climates with whatever moisture naturally occurs. Datura plant care specifies that potted plants require special care and annual repotting. The plants may lose leaves in winter season if left outside in milder climates but spring back in warmer temperatures. Datura plants growing in colder zones will need you to move the plant indoors or just let it reseed and start new plants.
• Fertilize in spring with a light flowering plant food high in nitrogen and then follow with a formula higher in phosphorus to promote flowering. Cut back errant stems, but otherwise, you don’t require pruning this plant. Staking should be necessary when the plant grows too quickly and has slender stems.
• Consistent watering helps ensure good early growth. Building about 2 to a 3-inch high mound of soil around a newly transplanted Datura, about 6 inches away from the plant stem, creates a watering well. Water added to the well when the top about 1 inch of soil begins to dry, or at 3 days interval, is absorbed slowly into the soil so it becomes evenly moist.
• Once the Datura begins to establish after about 2 weeks, you can reduce watering to once weekly or often enough so the top about 6 inches of soil doesn’t dry completely.

Diseases and pests that infect Datura plant

Datura avoids problems with large herbivores thanks to its poisonous leaves, but diseases and insects still attack it. Fungal diseases such as Septoria will spot the Datura leaves. All Datura species are among the septoria fungus host plants.

Leaf spots that show rings inside them are mostly due to Alternaria tenuissima, another leaf spot fungus. Some other fungus is responsible for root rot in this plant, such as Pythium (see a case where Pythium results in diseased Sunpatiens), Phytoptora, and Thielaviopsis.

Viral diseases (sometimes spread by insects) also contaminate Datura. Mosaic viruses and others may result in wilting and leaves folding up.

Insects may be to blame for spots and disease;

Aphids are moderately recognizable and can be seen with the naked eye. In addition to the damage, they inflict and also spread viral plant diseases.

Whitefly needs a magnifying glass but can also be dealt with easily. They do not usually spread diseases.

Commonly asked questions about growing Datura

Is it legal to grow at home?

Growing Datura legal to grow Datura at home. Just be aware of the high risk of poisoning to pets and kids. Sometimes just handling the Datura plant is enough to cause toxic effects.

What are the differences between Datura species?

Appearance and Potency (e.g. flower color) can vary between the species, but the effects are largely the same. Datura metel has the highest scopolamine content, and usually the maximum percentage of alkaloids overall, but the difference isn’t hugely significant. Unlike most species, the flowers and seeds of Datura wrightii and the flowers of Datura discolor are non-psychoactive.

Why are the leaves on my Datura turning yellow?

Inadequate watering can lead the leaves of the Datura plant to turn yellow. Datura uses a large amount of water during the growing season to promote their vibrant blooms, and if they don’t have enough water, you will notice the tell-tale signs of drought.

Why is my Datura not flowering?

There are mainly 3 things that can cause a bloom drop in Datura. They are low light, excessive heat, and not enough fertilizer. Datura prefers full sun to grow and bloom properly, so check your light properly. If your plant doesn’t receive at least about 5 hours of full sun a day the plant has to be moved to a place with more sun. As for excessive heat, there isn’t much you can do for that. You can try to shield the plant from excessive hot winds. Also, Datura blooms on new growth, watch for anything that inhibits new growth such as drought or insect damage.  Keep your plant moist especially during the summer seasons.
