老爺柿

老爺柿的基本資料

栽培難度

適合中級者

壽命

樹齡的資料很少

體型

在自然環境中為灌木～喬木，高度可達8公尺（盆栽為迷你～中等尺寸）

澆水

肥料（結果停止後至8月份施加較多，秋季追肥）

光照和放置位置

在日照充足、通風良好的地方結果效果更佳。小盆景應避免夏季強烈的西晒

澆水

在高溫多濕環境下容易根腐，應避免過濕。春季每日1～2次，夏季2～3次，表土乾燥時充分澆水

溫度和越冬

耐高溫和低溫（USDA區域7b左右）。小盆景、結果過多的株、秋季重新種植的株應保護免受凍結和乾燥風的傷害

用土和換盆

硬質赤玉土混入2～3成河沙。年幼樹隔年換盆，老樹3～5年一次。適期為秋季（8月下旬～9月中旬）或芽出前，應避免4～5月換盆

肥料

春季施肥容易導致落果，應保持控制。從結果停止至8月持續施肥，秋初停止一次，10月中旬再追肥

修剪和造型

新梢伸長後於2～3節處剪短以形成小枝。修剪和鐵絲造型的適期為2月下旬～3月和11～12月。枝條易折，應避免強曲

病害蟲和注意事項

注意蚜蟲、薊馬、介殼蟲。因為是雌雄異株，要欣賞果實需要雄株和4～5月的人工授粉

關於老爺柿

Rōya-gaki is a small Chinese persimmon bonsai known for diamond-shaped leaves and tiny orange fruit. It's dioecious, so fruit usually needs pollen from a male tree (some cultivars fruit without it), and it suits intermediate-level growers.

開始照料老爺柿前需要了解的7件事

1. 1Sun and Air Circulation

   Rōya-gaki thrives outdoors in a spot with plenty of sun and good air circulation. Strong direct sun in midsummer can scorch the leaves, so moving it to partial shade during the hottest stretch of summer is a good precaution.

2. 2Watering Basics

   Water thoroughly once the surface of the soil dries out. The tree can dry out quickly while fruiting or during summer heat, so keep an eye on soil moisture, and ease off on watering in winter when growth slows.

3. 3Well-Draining Soil Matters

   Because Rōya-gaki is prone to root rot in soggy soil, use a well-draining, well-aerated bonsai mix, such as a standard akadama-based blend. Good drainage keeps the roots healthy through the growing season.

4. 4When to Repot

   Repot once the roots have filled the pot. Doing this while growth has settled down puts less stress on the tree, and trimming the roots at repotting time helps keep drainage and growth stable afterward.

5. 5Winter Care

   As temperatures drop, Rōya-gaki tends to shed its leaves and enter a dormant period. Depending on your climate, some winter protection may be needed, so pay attention to where you keep it, and water more sparingly (without letting it dry out completely) during dormancy.

6. 6Check the Sex and Cultivar Name

   Rōya-gaki is dioecious, so the usual way to get fruit is to keep a male tree and hand-pollinate with its pollen. Some cultivars, however, set fruit without cross-pollination. When buying, check whether the tree is male or female and what cultivar it is, which makes later care much easier to plan.

7. 7Choosing a Good Specimen

   Leaf color, branch shape, and how fruit sets can vary from tree to tree, so look closely at the description as well as the photos when choosing. Since this variety suits intermediate growers, it helps to review the basics of its care beforehand if this is your first fruiting bonsai.

老爺柿的常見問題

Q.Is Rōya-gaki suitable for beginners?

A.Rōya-gaki is generally considered a variety for intermediate growers, with a few things to learn around watering, soil, and its male/female habit. Anyone with some basic bonsai experience should find it manageable.

Q.What does it take to get fruit on the tree?

A.Rōya-gaki is dioecious, so in most cases you need a male tree and hand-pollination with its pollen. Some cultivars set fruit without cross-pollination, so check whether the tree is male or female and what cultivar it is when you buy.

Q.How large does it grow?

A.In the wild it can grow as a shrub or small tree up to around 8 meters tall, but as bonsai it's trained into mini to medium-sized forms. That means it can be kept small and well-balanced even in a pot.

Q.How should I care for it in winter?

A.As temperatures fall, it tends to drop its leaves and enter dormancy. During this period, water less often and keep the soil somewhat drier than during the growing season.

Q.When is the right time to repot?

A.Repot once the roots have filled the pot. Doing it while growth has settled down, then trimming the roots and replanting in well-draining soil, helps minimize stress on the tree.
