今年も棗の幼果がコガネ成虫に齧られています。コガネムシ退治の方法で検索すると一般的に 出てくるのは容器に食器洗剤などの石鹸系の液体を入れて、それをコガネが着いている枝の下にかざして枝を揺さぶるとコガネが容器の中に落ちて来る。石鹸水で身動きがとれなくなるということだそうです。でも、うちの棗が受ける被害は夜のうちなので時間的に困難。そこで、いまひとつの方法として、ゼラニウムがあることを知りました。複数の米国の動画で言っていたのですが、コガネ成虫はゼラニウムを喜んで食べる。食べた後 体が麻痺して下に落ちるそうで、その間に収集・処分するそうです。
ということで、近所のJAをのぞいてみたら、何と1株だけ売れ残っていました。直径9cmのビニールポット入りの割には地上部が立派なので、苗の強健さがうかがえます。ついでに小さなビニールポットも買いましたが、これは発芽したクコの鉢上げ用です。
Jujube young fruits are getting eaten by Japanese beetles, as they were last year. When I Google how to get rid of the beetles, the most frequently cited method is to hold an open plastic bottle with soapy water under the branch with beetles, shake the branch and wait for the beetles to drop into the bottle. The soapy water immobilises the bugs. The problem is that my jujube fruits are getting eaten mostly during the night and I find it impractical to stand outside in the dark - I will be getting bitten by hundreds of mosquitoes. So, I looked up on the YouTube and found several US videos introducing the idea of using geranium plants. Apparently, Japanese beetles love geranium plants and after eating them, they become paralysed and drop onto the ground. I do not know for how long, but I will have the easy job of collecting and 'unaliving' them.
With this idea, I went to the nearby JA, although it was not the season for geranium plants. Amazingly, there was just one leftover geranium. The plant was in a 9cm diameter pot, but it looked quite robust even in the sweltering heat. I also got a pack of plastic pots for repotting the black goji berries which germinated recently.
今年の春に地植えにした皇帝の実の被害が特にひどいです。
Among all the jujube varieties, the young fruits of the 'Emperor' are getting the worst damage by beetles.
大株に育って欲しいので、鉢も余裕のサイズにしました。
Hoping that the geranium plant would grow big, I repotted it in a large pot.
ラベルによると「暑さにも負けない」品種だそうです。
According to the label, this variety is quite heat tolerant.
さっそく皇帝の根元に置きました。
I placed the pot next to the Emperor jujube.
皇帝は地植えにしたとたん、上へ上へと伸びてしまい、摘心した後でも樹高は2m以上になっています。横枝が短くて少ないですが、考えようによっては、下のほうの枝に他品種を高接ぎすればスペースを節約できます。
I planted the Emperor jujube in the ground in spring this year. Since then, the tree has shot up without bothering to grow side branches. Even after pinching the top, the tree is now taller than 2 meters. Although the side branches are short, I could use them to graft different varieties to save space.こちらはクコ。真ん中のポットは黒クコの発芽したものです。右側のポットは新たに種まきした赤クコで、まだ芽が出ていません。黒クコと同時に発芽した赤クコは、うっかりバケツ1杯の水を一気に空けた際、水の直撃を受けてポットの中身が全部飛び出してしまいました。なので再度 種まきしたものです。
Now to the goji berries. The pot in the middle contains black goji berries. The pot on the right contains red goji berry seeds that I sowed recently for the second time. The red goji
berries that germinated at the same time as the black ones were lost when I emptied a backet of water in the dark, without noticing that there was the pot. The whole thing was washed away. Thus, I had to start all over.
この黒クコ、あまりにヒョロくて扱いにくかったですが、
These dainty things are not easy to handle for me, but
なんとか5個を個別のポットに植え替えました。最終的に3個が育てば十分すぎるくらいです。
I managed to repot 5 of them individually. Ultimately, if 3 of these survive and grow, that would be more than enough.
6月中旬に届いた「静浜クコ」の苗は、
The Japanese goji berries that arrived in mid-June ,,,
今はこの状態です。門の横の壁の上に置いて、陽当たり・風通しを確保しています。以前は地面の上に置いていましたが、ウドンコ病にかかったのでここに移動させて解決しました。
this is how they look now. I keep the pots on top of the wall next to the gate, where it is sunny and there is plenty of air movement. When I used to keep them on the ground, the plants became mildewed. Moving the pots where they are now solved the problem immediately.
