Daphne odora, also known as Qianlixiang, is native to the region south of the Yangtze River basin in China and has medicinal value. Among its varieties, the golden-edged daphne is the most famous; it is a variety of Daphne odora and is renowned worldwide for its four excellences of "color, fragrance, form and charm," and is one of the world's three treasures of horticulture. It likes warm, humid and cool environments, and cannot tolerate severe cold or intense heat; its minimum overwintering temperature is 5 degrees. It dislikes direct sunlight, is suited to semi-shaded sites, and prefers loose, well-drained sandy soil.

For potted Daphne odora, keep the potting soil half dry and half moist, and apply fertilizer once each in spring and autumn. The fertilizer for Daphne odora must not be strong; it should be light and dilute. Nitrogen fertilizer and potassium fertilizer are the main types, often mixed with cake fertilizer and fishy fertilizer. But it must be a fully fermented fertilizer solution.

I. Four-season management of Daphne odora

Starting in early summer, avoid strong light exposure; potted Daphne odora should be placed in a shaded spot.

Daphne odora is relatively tolerant of pruning; before budding, densely growing small branches can be pruned away to improve ventilation and light penetration.

Repot and change the soil once every 2 to 3 years; when repotting, remove 2/3 of the old soil and appropriately trim away some overly long fibrous roots. This is generally done after the flowers fade or in autumn.

From mid-June to mid-September, Daphne odora basically stops growing and enters a semi-dormant state. During this period, fertilizing is strictly prohibited, rain protection should be done well, watering should be reduced, and a cool, ventilated environment should be maintained.

From the end of September to early October, it can receive light for 2 to 3 hours, and afterward the light duration should be gradually extended.

In October or early November, Daphne odora is brought indoors, and after being brought indoors it is placed in a position with long light duration.

In mid-November and early and late December, apply 1 dilute fertilizer solution each time. The flower buds of Daphne odora grow relatively slowly, so fertilizer must be applied, but not too frequently, too much, or too concentrated.

II. How to make Daphne odora grow fast?

1. Planting depth

When potting, the plant should be planted shallowly with the roots planted and the stem not planted; never bury the soil too deep.

2. Keep branches and leaves often moist

In dry weather and summer, frequently mist around the plant; the potting soil should be kept in a semi-moist state, with more misting and less watering.

3. Fertilizing

Every half month, water once with 0.2% ferrous sulfate or fermented diluted rice-washing water; this can both prevent the potting soil from becoming alkaline and increase nutrients. During the growth period, apply dilute fertilizer frequently, mainly dilute compound fertilizer; concentrated fertilizer is taboo.

4. Suitable light

In summer, place it under a shade frame to receive scattered light; in spring and autumn, let it see more light in the morning and evening; in winter, give it full light.

5. Pay attention to timely pest control

The roots of Daphne odora are soft and sweet and are easily attacked by ants, so timely control should be carried out.

III. What causes Daphne odora to drop its leaves?

1. Overwatering

Especially in winter, overwatering or failure to drain accumulated water after rain in time causes the potting soil to remain wet for a long time, resulting in root rot and leaf drop.

2. Improper soil use

If ordinary soil is used to plant Daphne odora, long-term poor drainage can cause root rot. In the early stage of the disease, the leaves droop and lose their luster; at this time, immediately repot, wash the roots clean, cut off the rotten roots, and change to loose, fertile, well-drained culture soil for replanting, and it can still be saved.

3. Potting soil too dry

Especially when the air is dry for a long time, the leaves are prone to curling and falling off.

4. Improper fertilizing

If concentrated fertilizer or raw fertilizer is applied, it can easily lead to root rot and leaf drop; if liquid fertilizer is accidentally splashed on the leaf surface, it can also cause the leaves to rot and fall off.

5. Strong light exposure

If exposed to direct sunlight in summer, the leaves are prone to turning yellow and falling off. During care, as long as attention is paid to reasonable fertilizer and water use, proper soil use and moderate light, leaf drop can be avoided or reduced.
