Datura

Datura should be watered regularly and consistently throughout the growing season. When the top inch or two of soil feels dry to the touch, it’s time to water. Aim to keep the soil damp, but be careful not to overwater. Too much water can lead to root rot and a decline in growth and health. When in doubt, opt for a light, less frequent watering.

Datura requires full sun for at least six hours a day, preferably eight, and bright indirect light for the rest of the day. Direct, hot sun can cause the flowers to burn and wilt. When kept indoors, keep the plants in a bright spot and turn them occasionally to promote even growth and flowering.

Datura prefers warmer temperatures between 65-75°F (18-24°C) and will survive mild frosts. If any frost is forecast, it is best to protect plants with a frost blanket. They can tolerate temperatures down to 40°F (4°C). In winter, consider moving the plant indoors.

Datura prefers warm, humid climates with good air circulation. If indoors, increase the humidity around the plant with a room humidifier and group plants together to help keep humidity levels high. To increase humidity around a planted pot, dampen the soil occasionally and mist the leaves.

Datura performs best in loose, well-draining potting soil. To ensure good drainage and a light texture, consider mixing a balanced blend of high-quality potting soil, compost, and perlite. For an especially airy, draining soil, add a handful of coarse sand or pine bark into the mix.

This plant is not heavy feeders but can benefit from a light monthly fertilization during the growing season. Use a water-soluble or balanced, slow-release 12-12-12 fertilizer for best results. Avoid over-fertilizing as this can lead to excessive foliage growth or nutrient burn. For indoor plants, use a lower strength fertilizer every two weeks.

Datura may be subject to some common garden pests, such as aphids, mealybugs, thrips, and whiteflies. To manage pests, manually remove as many as you can with a cotton swab soaked in rubbing alcohol for large infestations. Other treatment may include neonicitinoids or neem oil for heavy cases. Monitor your plant closely for early signs of irritation.

To give your Datura a good start, it is best to repot the plant in fresh, nutrient-rich potting soil once a year. It is typically best to repot in spring, once all danger of frost has passed. Prior to potting, gently shake off any excess soil stuck to the root ball and inspect it for any rot or diseased areas. Cut away any damaged or dead material before replanting. Use a pot that is just slightly larger than the current one.

To prevent your Datura from becoming leggy and overgrown, prune it regularly. Pruning back the stems by a third to two-thirds will help encourage bushier growth and more flowers. Don’t forget to give your plant a good shearing after flowering. Remove any dead or damaged growth to keep plants healthy.

Mulching with a layer of organic material such as shredded wood, bark chips, or coconut coir can help to retain moisture and protect the roots from extreme temperature changes. It also helps to improve the soil’s structure and prevent weed growth. A few inches of mulch should do the trick.

Datura can be propagated easily by seed. Seeds can be started indoors 4-6 weeks before the final frost, or, alternately, planted directly outside once the danger of frost has passed. When starting indoors, sow the seeds a quarter-inch deep into high-quality potting soil and water lightly to ensure all excess moisture is drained off. To speed up germination, give the planted seeds a good soaking and sit the pot in a warm, sunny spot until germination occurs. Once seedlings reach a few inches in height, transplant them outside into well-draining potting soil.

Datura is a relatively tall plant that may need support as it grows. Placing a tall, slender stake near the center of the plant will help to keep it upright in windy conditions or if stems become heavy with flowers. Alternatively, the plant can be trained up against a trellis or fence.

Datura prefers a rest period in winter when shorter days and cooler temperatures signal dormancy. While the plant can continue to be kept indoors during this time, it is best to reduce watering and allow the soil to dry out a bit between waterings. During this rest period, it is best to keep your Datura in a bright, cool location until spring when temperatures and water begin to increase.

Datura plants are highly poisonous and can be fatal if ingested. Extreme caution should be exercised when handling these plants. It is best to keep them out of reach of small children and pets. If ingested, it is important to seek medical attention immediately.
