How to Grow Obedient Plant: Planting Methods and Precautions

Obedient plant (Physostegia virginiana) - just hearing this name makes people wonder whether it is a very easygoing plant, which attracts many people. The flowers that obedient plant produces are not easygoing at all; their shape closely resembles a human mouth, and the flowers grow densely, with each small blossom lined up neatly in rows along the inflorescence, extremely orderly. Many people have fallen for this beautiful flower. Let us learn about its planting methods and some precautions together.

How to Grow Obedient Plant

1. Soil

The requirements for the growing medium are not high, but well-drained, fertile sandy loam gives the best growth. For ground planting, choose a site with deep, fertile soil and ample sunlight; for container growing, use fertile, loose potting soil.

2. Temperature

The growing site needs good sunlight exposure; plants in shaded areas tend to grow leggy and flower poorly. During the growth period of new plants, be sure to provide sufficient sunlight, and place the pot at a south-facing window. If light is insufficient for a long time, it will cause the branches and leaves to grow leggy and the internodes to become too long, affecting the plant's visual appeal.

3. Watering

For cut flower cultivation, space plants 30 cm apart. Spring to summer is the peak growing period; the growing site should maintain sufficient humidity, and never let it dry out, which would affect growth and flowering. During the growing period, keep the soil moist and provide fairly ample water; do not let the potting soil become overly dry.

4. Fertilizing

When preparing the soil, mix in well-rotted compost in advance as a base fertilizer. After the transplants have established, pinch back once to encourage more branching. For top dressing, apply nitrogen, phosphorus and potassium once a month, with a slightly higher proportion of phosphorus and potassium to promote flowering. Fertilize once every half month, but control the amount to prevent leggy growth.

Obedient Plant Planting Methods and Precautions

I. Obedient Plant Planting Methods

1. Soil

Obedient plant has low soil requirements and prefers loose, fertile, well-drained sandy soil. For ground planting, deep soil is required; for container growing, use fertile, loose potting soil.

2. Light

Obedient plant prefers a growing environment with ample light, so provide sufficient light when cultivating it. However, during the high temperatures of summer, do not expose it to direct blazing sun; appropriate shading is fine. Be careful not to let it become too shaded, which would cause leggy growth and poor or sparse flowering.

3. Watering

Obedient plant prefers a moist environment and is not drought-tolerant; dry summer weather will cause poor growth. During the growing period, keep the soil moist and water more, providing fairly ample water; do not let the potting soil become too dry.

4. Fertilizing

Use well-rotted compost as the base fertilizer. Apply nitrogen, phosphorus and potassium once a month, with a slightly higher proportion of phosphorus and potassium, to promote flowering. Be careful to control the amount of fertilizer to prevent leggy growth. When the inflorescences are emerging, apply 1-2 additional doses of phosphorus fertilizer or a specialized fertilizer.

5. Temperature

Obedient plant prefers a warm environment; the suitable growing temperature is around 18-28 degree C, and it has fairly strong cold tolerance.

II. Obedient Plant Growing Precautions

1. Pruning

Prune old plants once in winter or early spring; plants over 3 years old should be renewed and replanted. For container growing, use a large pot; plant 2-3 plants per 8-inch pot, as more potting soil benefits root spread. After 1-2 years, division and repotting should be forced. Tall plants tend to lodge; for cut flower cultivation, set up stakes when necessary or use nylon netting to secure the branches.

2. Pest and Disease Control

Obedient plant is often affected by rhizome rot, leaf spot and rust. If rhizome rot occurs, promptly pull out and burn the affected plants to prevent spread.

How to Propagate Obedient Plant

I. Division Propagation

1. Timing

Division propagation is carried out before spring sprouting. Spring and autumn are the most suitable seasons for division.

2. Selecting Plants

Generally, use obedient plant plants about 3 years old for division.

3. Specific Method

Cut young plantlets or underground rhizomes from the mature plant and plant them separately. Alternatively, in autumn, take healthy new shoots and insert them as cuttings in a well-drained sand bed, then transplant after they have rooted.

II. Cutting Propagation

1. Timing

Cuttings can be taken throughout the growing period of obedient plant, but are generally taken from April to May each year.

2. Selecting Plants

From April to May, take new shoots of about 10 cm that have sprouted that year.

3. Specific Method

Insert the cuttings directly into the potting soil, 2-3 per pot. After inserting, be sure to maintain moisture; they will root in about 2 weeks. After new shoots emerge, fertilize about once every 10 days. When the new shoots grow to about 10 cm, keep only 2 nodes and pinch off the growing tips to control plant height and encourage branching.

4. Cutting Care

During the growing period, provide ample sunlight, and shade appropriately in summer. Pay attention to maintaining moisture; when the weather is dry, spray water on the leaves to keep them moist. First; after the flowers fall, apply manure fertilizer 2 times to promote new shoot growth. In winter, move obedient plant to a sheltered spot.
