         <title>近幾年我家的盆栽,越來長的越不好,有換過培養土,但是就是長的不好,像葡萄去年還有結果或開花,桂花樹去年也有開花,日日春也是,今年都長的不好~因為我覺的換盆這種大動作很麻煩,所以有朋友推薦我使用&quot;草木灰&quot;,請問草木灰是我拿就有盆栽裡的那些枯葉就可以嗎?還有草木灰功效好嗎?之前用泡過茶的茶葉都給我引來蚊蟲~謝謝各位指教</title>

         <title>草木灰是鹼性的，能用來中和偏酸性的土壤，補充鉀肥，改善土壤結構，但不適合用於本身已偏鹼性或種植喜酸性植物（如藍莓、杜鵑、茶花）的土壤，以免造成土壤過鹼，影響植物吸收養分。使用草木灰時，需先了解土壤酸鹼度，並避免過量，可與堆肥混合或稀釋後使用。
