掌葉槭
Acer palmatum 'Crimson Prince'
植物簡介
A colourful, spreading, deciduous tree, with rough grey bark and reddish stems, said to be an improved selection of 'Bloodgood' but with lobed, palmate leaves a richer red and more resistant to heat scorch, that turn fiery crimson in autumn; small red spring flowers, and winged fruits in autumn
屬描述
Acer can be deciduous trees or large shrubs with paired, often palmately-lobed leaves and small flowers followed by characteristic winged fruits. Many have fine autumn colour, and some have ornamental stems
生長條件
—
東向、西向、北向
黏土、壤土、砂質
濕潤排水良好 · 酸性、鹼性、中性
全台適種
H6｜最低耐溫 -20 至 -15°C
4-8 公尺
冠幅 2.5-4 公尺 · 5-10 年
照顧指南
Grow in any moisture-retentive, well-drained soil in a sheltered position. Leaf colour is best in partial shade, although full sun can be tolerated if soil is reliably moist. Leaf scorch can be caused by lack of soil moisture or excessive exposure. See Japanese maples cultivation
Pruning group 1, only from late autumn to mid-winter
Propagate by softwood cuttings, layering or by grafting. Plants grown from seed are unlikely to come true, but may still be garden worthy
May be susceptible to aphids and scale insects, including horse chestnut scale May be susceptible to Verticillium wilt, Acer leaf scorch and honey fungus

滴灌與噴灌系統的效率比較：數據說話，選對才省水省錢
在灌溉系統的選擇上，園藝新手常常陷入一個迷思：「噴灌看起來很專業，裝了就對了。」但實際上，灌溉效率的差距可以高達兩倍以上，選錯系統不只浪費水費，還可能讓你的草坪或菜圃一直處於亞健康狀態。
秋播種子的層積催芽技術：打破休眠的冷處理科學
每年秋天，許多園藝愛好者把種子放進土裡，等了整個冬天卻毫無動靜。原因不是種子死了，而是沒有做對一件事——層積催芽（seed stratification）。這個過程模仿自然界冬季的溫濕循環，打破種子的休眠機制，讓它在春天準時萌發。
酢漿草入侵草坪的根治方案：從生物學弱點找出真正有效的方法
台灣幾乎每個草坪管理者都和酢漿草（Oxalis spp.）打過仗，而且多半以敗仗告終。輕鬆一拔，幾週後它又滿地都是；用除草劑噴了一輪，結果草坪也受波及。問題不在方法不對，而在對它的生物學了解不夠深。這篇文章要把酢漿草的繁殖機制和弱點說清楚，然後設計一套有邏輯的三階段根治方案，讓你不再繞圈子。
