How to Grow Hosta? Cultivation Methods and Precautions

Hosta is a fairly common flowering plant in China, and almost anyone who has seen a hosta flower praises it for being pure white and beautiful. In addition, this plant gives off a rich fragrance that can be smelled from far away. And besides its extremely high ornamental value, the whole hosta plant can also be used as medicine, so it is very good if you can grow a pot of it at home. Now follow the editor to learn about its cultivation methods.

How to Grow Hosta

1. Soil

Hosta is not very picky about soil, but it grows better in moist, fertile, well-drained soil. So when choosing a pot and mixing soil, put the larger particles at the bottom and spread a layer of fine soil on the surface.

2. Watering

Hosta likes a shady, damp environment, and especially during the growing period, it is best to keep the soil moist. But watering must be controlled in amount. Too much watering will cause root rot and yellowing leaves. When the air is dry, spray water on the leaves every day to prevent the leaves from drying out and wilting.

3. Sunlight

Hosta does not like light, and it can grow very well with just weak light. Do not place it in strong light for care, as that can easily cause the leaves to turn yellow and wither. Plant it on the shady side of a building or under the shade of a large tree.

4. Temperature

Hosta flowers are pure white, and the plant has strong vitality and relatively strong cold tolerance. It is not too late to move it indoors at the end of November, and as long as the indoor temperature is not lower than 0°C, it can survive.

5. Fertilizing

Hosta blooms from July to September, so it needs extra care in the two months before flowering. Start fertilizing in early May, once a month with a thin, mild fertilizer. When it blooms in July and August, the number of fertilizing times can be appropriately increased, and stop fertilizing in late September. After each fertilizing, water and loosen the soil promptly so the soil stays loose and well aerated.

Hosta Cultivation Methods and Precautions

I. Cultivation Methods

1. Soil: Hosta is not choosy about soil, but it grows better in moist, fertile, well-drained sandy loam.

2. Watering: During the growing period, it is best to keep the soil of hosta constantly moist. If watered too much, it easily causes root rot and yellowing leaves. In summer, the water supply must be sufficient. When the air is dry, spray water on the leaves every day to prevent the leaves from drying out.

3. Sunlight: Hosta avoids scorching sun, so it is best to plant it on the shady side of a building or under the shade of a large tree and other places where sunlight cannot shine directly.

4. Temperature: Hosta is vigorous and cold-resistant. Move it indoors at the end of November, and it is best if the room temperature does not freeze.

5. Fertilizing: Start fertilizing hosta in early May, applying a thin liquid fertilizer about once a month. In July and August it can be slightly more concentrated, and stop fertilizing after late September. After each fertilizing, water and loosen the soil promptly so the soil stays loose and well aerated.

II. Precautions

1. Pest and disease control

In summer, prevent damage from snails and slugs, and be sure to spray hosta with the relevant pesticides in time.

2. Choosing the planting site

Because hosta likes shade, it is suitable to plant it under trees, on the north side of buildings, or in secluded spots not exposed to direct sunlight. Never plant it in a sunny spot.

What to Do If Hosta Roots Rot

1. In terms of care

Water in the right amount and at the right time. Wait until the soil is dry before watering, and water thoroughly, but avoid water accumulation. In summer, watering can be appropriately increased. Before planting hosta, disinfect the soil, regularly remove dead branches and fallen leaves, and give it a good growing environment.

2. Take out the plant and change the soil

Take the hosta out of the pot, remove the rotted parts of the roots, put it in a shady place to dry, and then you can directly change the soil. It is best to use a mix of potting soil and sandy soil, which has good drainage and can also retain nutrients.

3. Medicinal treatment

In summer or when the hosta's growing environment is relatively humid, spray it with a treatment. Simply spray a fungicide, once every two months. Because spraying a fungicide after the plant's roots have already rotted is too late, spraying it in advance like this is preferable.

Hosta Propagation Methods

1. Taking roots for division

The best seasons for division are April to May or October to November each year. Divide once the leaves turn yellow and wither. Take out the hosta, remove the soil around the roots, divide the rhizomes into sections, keeping at least 2-3 buds on each section. Be careful to keep the root system, as it makes survival easier.

2. Dividing and potting up

Put the prepared substrate into the pot, and be sure to place it in order, coarse first and then fine. Bury the divided rhizomes into the soil. Plant 1-2 plants per pot, not too densely, otherwise flowering will be affected. After planting, water a small amount and place it in the light.

As a plant that can be enjoyed both for its flowers and its leaves, hosta is naturally deeply loved by everyone. But if you want to grow hosta well, it still depends on the daily extra care from fellow gardeners, and every aspect must be taken care of.
