Propagation of Turnera Ulmifolia
Propagation of Turnera ulmifolia can be done through the following steps:
- Seed Collection: Harvest mature seeds from Yellow Alder when the seed capsules have turned brown and are dry. Gently remove the seeds from the capsules and discard any damaged or discolored ones.
- Seed Preparation: Soak the collected Yellow Alder seeds in warm water for 24 hours to soften their outer coating, which promotes better germination.
- Seed Sowing: Fill a small pot or seed tray with a well-draining potting mix. Place the Yellow Alder seeds on the surface of the soil, lightly pressing them down, but avoid burying them too deep.
- Moisture and Cover: Mist the seeds with water to moisten the soil. Cover the pot or tray with a plastic bag or a clear plastic lid to create a greenhouse-like environment that retains moisture. This helps in maintaining humidity levels and facilitates germination.
- Germination: Place the covered container in a warm and bright location, but away from direct sunlight. Maintain a consistent temperature of around 21-24°C. Germination can take anywhere from 1 to 4 weeks, so be patient and check regularly for signs of sprouting.
- Transplanting: Once the Yellow Alder seedlings have developed two to three sets of true leaves, they are ready for transplanting. Gently lift them from the seed tray using a small spoon or fork and carefully transfer them into individual pots filled with well-draining potting soil.

Requirements of Growing Turnera Ulmifolia
Turnera ulmifolia thrives in bright, indirect sunlight to partial shade. Ideally, Yellow Alder should receive at least 4-6 hours of direct sunlight each day, but it can tolerate some shade as well.
When grown in hotter climates, providing some afternoon shade can help protect the plant from excessive heat and prevent leaf scorching
Yellow Alder is well adapted to well-drained soil that is rich in organic matter. Turnera ulmifolia prefers a slightly acidic to neutral pH range of 6.0 to 7.0.
The soil should have good water retention capabilities while also allowing excess water to drain freely to prevent waterlogging, which can lead to root rot.
Turnera ulmifolia requires moderate and consistent moisture levels in the soil. It’s important to water the plant regularly, especially during dry periods or when it’s newly planted, to establish a healthy root system.
Water deeply, allowing the water to penetrate the root zone, but avoid overwatering or creating waterlogged conditions, as this can lead to root rot. Before watering again, it’s best to allow the top inch of the soil to dry out slightly.

Turnera ulmifolia is sensitive to frost and cannot withstand freezing temperatures. Ideally, temperatures should range between 15°C (60°F) and 29°C (85°F).
The plant prefers moderate to high humidity levels, as it is native to tropical and subtropical regions. Adequate humidity helps promote healthy foliage growth and flowering.
If you live in a dry climate or an area with low humidity, you can increase humidity around Turnera ulmifolia by misting the leaves regularly with water or placing a tray filled with water.
Care for Turnera Ulmifolia
Turnera ulmifolia benefits from regular fertilization to support its growth and flowering. Use a balanced liquid fertilizer, diluted to 1/2 of its strength, once a month.
Additionally, incorporating organic matter, such as compost or well-rotted manure, into the soil during planting or as a top dressing can provide natural nutrients and improve soil fertility for Yellow Alder.
Pruning Turnera ulmifolia is generally minimal but can be done to maintain its shape, remove dead or damaged branches, and promote better airflow within the plant. It can be performed in early spring or after the flowering period.
Trim back any overly long or leggy branches to encourage bushier growth and promote a more compact form.
