I. 紫陽花 挿し木 の 時期

適切な時期

紫陽花を挿し木で増やすのに最適な時期は、中春から初夏（4月下旬～6月上旬）です。この時期は、気温が上昇し、日差しも強くなり、植物の成長が活発になるため、挿し穂が根付きやすい環境が整っています。

ただし、地域によって気候が異なるため、適期は多少前後する場合があります。寒冷地では、気温が安定する5月中旬以降が適期となるでしょう。また、温暖地では、4月下旬から挿し木を開始することができます。

挿し穂の採取

挿し穂は、健康で病気のない親株から採取します。茎は、太すぎず細すぎず、鉛筆程度の太さが理想的です。また、葉が3～4枚ついている節のある部分を選びましょう。

挿し穂を採取する際は、清潔な剪定ばさみを使用し、親株を傷つけないように注意します。挿し穂の長さは、10～15cm程度が適しています。

When to Take Cuttings

The best time to take cuttings from hydrangeas is in mid to late spring or early summer, when the stems are soft and pliable. Avoid taking cuttings from woody or brittle stems, as they are less likely to root successfully.

Selecting the Right Cuttings

Choose healthy, disease-free stems with multiple sets of leaves. The stems should be about 6-8 inches long and have a few nodes, which are the points where roots will form. Avoid taking cuttings from stems that are too thin or too thick, as they are less likely to root successfully.

• Healthy, disease-free stems
• Multiple sets of leaves
• 6-8 inches long
• A few nodes

Preparing the Cuttings

Once you have selected the right cuttings, you need to prepare them for planting. First, remove the bottom leaves from the cuttings, leaving only the top two or three sets of leaves. Then, make a clean cut at the bottom of the cutting, just below a node.

• Make a clean cut at the bottom of the cutting
• Just below a node

Planting the Cuttings

To plant the cuttings, you will need to create a hole in the soil that is about 6 inches deep. Place the cutting in the hole and firm the soil around it. Water the cutting well and keep it moist until it has rooted.

Care After Planting

After you have planted the cuttings, you need to provide them with proper care to help them root and grow. Water the cuttings regularly, especially during the first few weeks after planting. You can also mulch around the cuttings to help retain moisture and suppress weeds.

With proper care, your hydrangea cuttings should root and grow into new plants within a few weeks. You can then transplant them into your garden or keep them in pots.

III. 紫陽花 Propagating From Cuttings

When to Take Cuttings

Mid to late spring or early summer is typically when hydrangeas are actively growing and sprouting new shoots. Cuttings taken during this period will naturally contain more growth hormones. These hormones play a crucial role in stimulating root development and promoting successful rooting. To determine if a cutting is ready to be taken, gently bend it. A healthy cutting will snap cleanly, indicating it possesses sufficient maturity and energy to develop roots.

Selecting the Right Cuttings

Choosing healthy, vigorous stems increases the likelihood of successful rooting. Look for stems that are at least 6 inches long and have several sets of leaves. Avoid stems that are weak, diseased, or have signs of pests or damage. Select stems that are not flowering, as flowering can divert energy away from root growth.

Preparing the Cuttings

Before planting the cuttings, prepare them by removing the lower leaves from the bottom 2 to 3 inches of the stem. This will create a clean area for the roots to form. You can also choose to dip the cuttings in a rooting hormone. Rooting hormones are available at most garden centers and can help promote root growth.

Planting the Cuttings

To plant the cuttings, fill a container with a well-draining potting mix. Make a hole in the soil with a dibber or pencil and insert the cutting into the hole. Firm the soil around the cutting to secure it in place. It is essential to water the cuttings regularly to keep the soil moist but not soggy.

Care After Planting

After planting the cuttings, provide them with proper care to encourage root development and growth. Keep the soil moist but not soggy by watering regularly. Avoid overwatering, as this can lead to root rot. Place the cuttings in a location with bright, indirect light. Direct sunlight can scorch the leaves and hinder growth. Partial shade is ideal for hydrangeas. You may also consider mulching around the cuttings to help retain moisture and suppress weeds.Here are some related posts that you may find helpful:* [紅葉 壁面 飾り](https://nippongardening.com/紅葉-壁面-飾り/)* [花壇 おしゃれ 雑貨](https://nippongardening.com/花壇-おしゃれ-雑貨/)* [バンクシア 種類](https://nippongardening.com/バンクシア-種類/)
