獅子頭

獅子頭的基本資料

栽培難度

適合中級者

壽命

品種壽命的資料很少

體型

盆栽為小品至中品，也作為庭木流通（成木尺寸的資料較少）

澆水

肥料（春季和秋季，適量施用）

日照和放置場所

陽光充足、通風良好的場所。因葉片密集，需間隔花盆讓風通過。梅雨季後至9月上旬要遮光以防葉片曬傷

澆水

葉片展開後易乾。春季每天2次，夏季2-3次，冬季每1-2天1次，以株元為準。夏季缺水會損害紅葉效果

溫度和越冬

耐寒性強（紅楓為USDA 5區）。落葉後經歷2-3次霜凍，隨後需避免乾風和晚霜，妥善保護

土壤和移植

用透水性好的土壤，移植在3月芽出前進行。每2-3年進行1次，迷你品種每1-2年進行1次，整理根系以促進細根增長

肥料

4月中旬新葉定形時施有機肥料，5月追肥。秋肥在8月中旬至9月結束，以促進紅葉

修剪和造型

3月中旬至4月中旬摘除中心芽。因葉片密集，應採疏葉而非全葉修剪，以使內部見光和通風。修剪在落葉前後進行

病蟲害和注意事項

因葉片混合，梅雨季後需防止白粉病和葉片悶蒸。新芽易受蚜蟲。使用濃度較低的藥劑時也需注意藥害

關於獅子頭

Shishigashira is a Japanese maple cultivar prized for its thick, curled leaves clustered at the branch tips, with attractive autumn color. Suited to small-to-medium bonsai, it's best for intermediate growers.

開始照料獅子頭前需要了解的7件事

1. 1Light & Airflow

   Like most Japanese maples, Shishigashira prefers a spot with good sun and airflow. Strong direct west sun in midsummer can scorch the leaves, so partial shade or light filtering in the afternoon is a safer bet.

2. 2Watch for Dryness

   Because the thick, densely clustered leaves cover the pot, the soil can dry out faster than expected. Water thoroughly once the surface soil dries, and be especially careful not to let the pot dry out during summer.

3. 3Well-Draining Soil

   As with Japanese maples generally, it does best in soil that balances drainage with moisture retention. A bonsai potting mix or an akadama-based blend is a practical starting point.

4. 4Regular Repotting

   The roots tend to fill the pot fairly quickly, so repotting every few years is recommended. Do this before the buds start moving in spring, gently loosening the root ball before placing it in fresh soil.

5. 5Thin Leaves for Airflow

   Shishigashira's leaves crowd tightly at the branch tips, so the interior easily gets stuffy. Full defoliation to force a second flush tends to weaken maples in general, so avoid it and instead thin out leaves selectively to let light and air into the canopy. This also helps prevent powdery mildew and humidity problems from the rainy season onward.

6. 6Winter Care

   After the leaves drop, some exposure to cold helps set up healthy budding the following spring, but extreme dryness and hard frost should still be avoided. For potted trees, choose a spot where the roots won't freeze.

7. 7Choosing a Healthy Plant

   When selecting one, check that the leaves are thick and tightly curled, and that they cluster densely at the branch tips. A tree with little leggy growth and tightly spaced branching tends to show the cultivar's characteristic leaf texture more clearly.

獅子頭的常見問題

Q.Is Shishigashira suitable for beginners?

A.Shishigashira is generally considered a variety for intermediate growers, so it's best approached after gaining some experience with Japanese maples. Basic care like watering and placement follows the same principles as other maples, so starting with an easier cultivar first can help build a solid foundation.

Q.How is it different from a regular Japanese maple?

A.The biggest difference is the leaf shape: Shishigashira has thick, curled small leaves that cluster densely at the branch tips. This looks very different from the thin, flat-opening leaves of typical Japanese maples, so the cultivar can be identified by its foliage alone.

Q.Is it better suited to a pot or the garden?

A.Shishigashira is trained as a small-to-medium bonsai and is also sold as a garden tree, so it can be grown either way. Potted and garden-grown trees differ in how often they need watering and repotting, so it helps to match your care routine to the growing style you choose.

Q.When does the autumn color appear?

A.Shishigashira does develop attractive autumn color. The exact timing varies with your local climate and region, so it's best to use your area's general autumn foliage season as a guide.

Q.How often does it need repotting?

A.As a general guide, repotting every few years before the roots become pot-bound works well. The exact interval depends on pot size and growth, so it's best to check the root condition periodically and decide accordingly.
