1.Clean seeds, sanitize the growing soil or medium.
1.種子要先洗淨+殺菌+消毒.
2.Prepare pot or container fill with soil or medium.  Moist the soil then place the seeds on top of soil, do not cover the seeds.  Cover the pot or container with re-sealable bag or clear plastic bag and then store in the fridge.
2.準備點播用淺的苗盆,土壤用田土(沒有的話用培養土也可以)+排水佳介質+有機肥1比1比0.25點播於小苗盆上不覆土. 用夾鍊袋/塑膠袋封起後冰箱冷藏庫中冷層積,等發芽.
3.Check and open once a week for air circulation.  About 3-6 months seeds will germinate.
3.一週檢查一次順便透氣. 約3-6個月發芽.
4.Pick the seeds out to pot them individually after once they are growing.  Grow the seedlings partial shade location with good air flow and keep soil moist.
4.出芽後1個種子單獨一小盆為佳. 置於半日照通風處生長. 要保持一定濕度.
5.Apply light organic fertilizer after seedlings have 6 leaves.  Change to full sun location.
5.等本葉長出6片後小盆換中盆. 施有機薄肥,改全日照.
*Because Linden tree do not produce lots of viable seed, under 8%.  So there are not too many seedlings you can find under the tree.   Many thought their seeds require 3-5 years of germination period.

*此種樹種子雖多,有胚的有效種子卻比率相當少,低於8%. 再加上自然環境下能發芽的很少. 所以有人誤以為要3-5年才會發芽.Once they are germinated, they grow fast without any special care!  Small flowers but so many of them with strong nice fragrance.  Linden trees flower in late spring to early summer.  Great food source for bees. — My family and I have tasted Linden honey, nice flavour!但是一旦發芽後卻長得很快,容易栽種,不需怎樣特別的照顧. 花小而多有強香. 春末夏初開花,花開滿樹是很好的蜜源. –我嚐過的椴花蜜有很特別的滋味,家人都非常喜歡.

直播可要蠻久的…不鼓勵.
Not suggesting direct sow method.  It will take long time to see the result.
1.Use temperature changing to stimulate seeds:
1.種子不破殼的話可用溫差法:
For 3 days, soak seeds in warm water in day time and at night in fridge in a small re-sealable bag.  Repeat this method until seeds germinate, it should be about 1-2 months.
After seeds germinated, put each seed in a small pot with well drained soil or growing medium in partial shade location.
Transplant seedlings to bigger pot when they have 5-6 leaves.  Change to full sun location.
白天泡溫水(要換水)3天,晚上睡前裝在小夾鍊袋放冰箱冷藏. 反覆如此直到伸出小白腿再一株一盆假植. 土壤排水要良好,土壤不拘. 約1-2個月內發芽.發芽後先半日照到4-6片本葉後轉全日照.
2.Light sand the seeds and germinate them in warm temperature:
2.破殼後溫暖濕悶法:
Light sand the seeds with sandpaper or nail clipper built-in file then soak in clean warm water for 3 days.
Put the seeds in a re-sealable bag or container with moist sanitized moss as growing medium, cover and place in warm location.  Seeds should germinate in 2 weeks.
Pick the sprouted seeds out to plant in individual small pot in partial shade location.
Transplant the seedlings to bigger pot when they have 4-6 leaves.  Full sun.
用砂紙或指甲剪的挫刀將外殼邊緣磨掉一點點後泡乾淨溫水3天後裝在有乾淨消毒過的濕水苔的夾鍊袋或有蓋容器,放在溫暖處,約2週內發芽.發芽後撿出個別種在小盆內,半日照.小苗們到4-6片本葉後轉全日照.
This pea family beautiful shade tree is very easy to grow.  It is OK to grow in a pot if you don’t have big land to grow them.   From seed to flower will take 4-6 years.
這加拿大紫荊開花時是先花後葉是非常美麗優雅的庭園樹種,若是無足夠空間可以地植,它是可以盆植的.  種子到開花約4-6年.

加拿大紫荊 Canadian Red Bud (Cercis canadensis)

ImageImageImage算大型樹吧!  成熟樹高可達約10米, 寬幅約為10-12米,耐陰,春天開粉紅色像豆類花的花形的小花,先花後葉,葉心型,非常強健耐寒,用種子繁殖. 五月現在正盛開!  很繽紛詩意的感覺啊!  圖示為我拍的客戶家隔壁的樹.

Usually it grows  about 9-10 m (20–30 feet) tall with a 8–10 m (25–35 foot) spread.  Flowers like pea flowers in spring around May.  Leaves like heart shape, come after flowers.  Tolerate shade.
