LYCORIS POISONS PEONY-- REGRET FOR MY IGNORANCE (我が無知に後悔、リコリスがシャクヤクを枯らす)


We pulled all lycoris out of the peony bed,
and replaced old soil with new soil last Sunday.
We planted a tree peony 'High Noon' in a vacant space
where peony 'Daifuki' had grown. 
I want to explain the reason why I pulled out lycoris and changed soil.
This is a story of suffering of peony due to my ignorance.

 先週の日曜日、シャクヤクの花壇からリコリスを全部引き抜き、
古い土を新しい土に入れ替えました.
大富貴がかつて育っていた所に
ボタン「ハイヌーン」を植えました.
なぜリコリスを抜いて土を入れ替えたのか理由を説明したいと思います.
それは私の無知が原因のシャクヤクの受難のお話です.


I made a raised bed for peony in 2011
and planted a tree peony 'Miyazakura' and six varieties of herbaceous peony.
They bore many beautiful flowers for a few years.

'Daifuki' herbaceous peony died last year.
シャクヤク '大富貴'は去年枯れました

 シャクヤクの花壇を2011年につくり、
ボタン「宮桜」とシャクヤク6品種を植えつけました。
2,3年はよく花をつけました.


I planted white-flower lycoris bulbs together in the peony bed.
Lycoris flowers in September, and leaves grow after flowering until early spring.
The leaves die in spring, and they are dormant in summer.
I thought that peony and lycoris take turns,
and there is interests in the bed in all seasons.
But it was absolutely wrong idea for peony.

冬のリコリスの葉
 シャクヤクの花壇にはリコリス(ヒガンバナ)を一緒に植えました.
リコリスは九月に花を咲かせ、そのあと葉が茂って早春まで茂っています.
春には葉が枯れて、夏は休眠します.
シャクヤクとリコリスは交代して
四季を通して興味を引いてくれくれると考えました.
しかし、シャクヤクにとってはまったく間違った考えでした.


The tree peony died three years after,
and every peony bore much fewer flowers year after year.
The peony bed with few peony flowers with Allium cristophii
わずかな数のシャクヤクの花とアリウムの花
3年後にボタンは枯れ、
シャクヤクたちも花数が年々減りました.


I happened to conceive the idea that lycoris had some bad influence
to other plants, and research it.
I found the fact that lycoris produces lycorine (toxic crystalline alkaloid),
which inhibits growth of other plants. 
How awful it it!
I was shocked to know that I tormented peony....
Immediately I decided to pull all lycoris out of the bed,
and to remove soil contaminated with lycorine. 



 リコリスがひょっとして他の植物に悪い影響を及ぼすことがないか
との考えが浮かび調べてみました.
すると、リコリスはリコリンという有毒なアルカロイドを産生し
他の植物の生育を阻害することを知りました.
何ておそろしいこと!
シャクヤクを痛めつけていたと知ってショックでした.
すぐに、リコリスをすべて取り除いて
リコリンに汚染された土も除くことを決心しました.


I bought a young plant of tree peony 'High Noon' with yellow flowers
and temporarily placed in the bed.
I'm planting it when flowers are over.

Viola and Allium were re-planted.

花壇に仮置きしました.
花が終わったら植えつけます.

    I hope that your peony bed will be more health for your new peony. It is a bit like rose replant disease where if you plant a new rose where an old rose was, the new rose will never do well as the roots send out a growth inhibitor to reduce competition. You need to replace the soil as you had to do with the peony bed. The yellow peony looks beautiful.

    Best wishes

      Thanks for your comments.
      I do really hope peony grows well this season, and bears lots of flowers next season.
