The very mysterious leaf of Eucalyptus.

This is a leaf of Eucalyptus (Corymbia) maculata.

Very mysterious !














The leaf is growing from the leaf.





The mysterious phenomenon has happened.







Botanical name : Eucalyptus (Corymbia) maculata
Common name : Spotted gum

The minimum temperature is an important key

In the early summer of this year, the growth of the seedling was slow.

I felt early-morning temperature to be chilly.

Does temperature influence the growth of Eucalyptus?

It was as follows when I examined temperature.

I made  a graph of temperature of 2010 and 2011 and 2012.

The minimum temperature from June 20 to July 10 lowers in comparison with the last year.

The seedling becomes fast-growing, when keeping minimum temperature more than 23 degrees.

The growth speed of Eucalyptus seems to influence the temperature.

I hope that a flower blooms.

Eucalyptus orbifolia is a kind to inhabit the desert zone of Northern Territory and Western Australia.

Osaka Japan is a temperate humid climate.

I think the different environment to be that the stress is big for E.orbifolia.

In this stress, I am surprised at E.orbifolia having a bud.

I hope that a flower blooms.

Is this a bud of a flower?

This is Eucalyptus gillii.

Tree height is about 50 cm.

I found the unnatural branch on July 5.

It is continuing observing since then.

Although it is a small seedling, it seems to have a bud of a flower.

I expect that a flower blooms.

Summer in Japan for Eucalyptus

Many seedling of Eucalyptus died in summer of 2011.

Was the summer of 2011 too hot for the eucalyptus?

This graph is comparison of the temperature of 2010 and 2011.

Hirakara-shi Osaka japan.


I think about the same even if I compare the temperature of 2011 with the temperature of 2010.

Temperature was not a cause and would be caused by other environment. .....?



I examined the daylight hours and precipitation.

The unit of the daylight hours is hours.



The unit of precipitation is mm.

In periods from May to September,




The daylight hours of 2011 was decrease more 90-hour than 2010.

The precipitation of 2011 is increase of 140mm than 2010.

I think that it was the environment where the soil of the flowerpot is hard to dry.

Drying of the soil of the flowerpot will be an important thing for Eucalyptus.

Eucalyptus and oyster husk calcium hydroxide

I read "The method to let Okamurasaki lavender bloom in Kagawa" of Ossan-lavender san (user name).

You sprinkle a large quantity of organic lime, and you sprinkle a large quantity of water, and let's dissolve organic lime.
He said,  do not mind the freeze.

I sprinkled a large quantity of oyster husk calcium hydroxide on a eucalyptus and dissolved it with a large quantity of water in spite of the coldest time.

I photographed this in January.

Because I have sprinkled it on all pots, I do not understand the difference of the growth when I do not sprinkle it.

I add some information,

In Australia,
Limestone of world heritage Pinnacle,
The beautiful shore of the sand bar that limestone was pared off,
I feel that there are many things which assume lime a keyword.

Some of Eucalyptus growing wild should be brought up in the ground of the limestone that the bottom of the sea rose.
In that case, what does a eucalyptus grow in the nourishment source in in desert?
I thought the nourishment source of the eucalyptus to be calcium water and mineral water.

But, there may be a factor elsewhere

If keyword is a calcium, a mineral, and calcium hydroxide , is oyster husk calcium hydroxide one of the choices as a nourishment source of the eucalyptus?
I have sprinkled a large quantity of oyster husk calcium hydroxide like Hanasakajii-san without the consequences.

As a result, I seemed not bad for a eucalyptus.

Eucalyptuses doing its best #2

Because a photograph of yesterday's Eucalyptus perriniana was indistinct, I retook it.

Botanical name : Eucalyptus perriniana
Common name : Spinning gum














Furthermore,

Botanical name : Eucalyptus nova anglica
Common name : New England Peppermint / Black Peppermint



The leaf becomes brown and is dry.


It died by cold wind of the winter season.

But a sprout came out of the axil of the dead leaf of a low position.









I am not sure whether it is a sprout.

Botanical name : Eucalyptus tetraptera
Common name : Square-fruited mallee




The leaf becomes brown and is dry.


It died by cold wind of the winter season.

Will it be a sprout?










They are strong !

I seem they say, "Good luck, do your best, OK?".
