25.2.2025: Various acorns from the south of the USA for sale

It took a long time and a lot of negotiations, but now they are here. Various acorns (oak species) from the south of the USA.
E.g. from North and South Carolina, Georgia, Alabama, Mississippi, Louisiana, Arkansas, Tennessee and Kentucky.
Most of the oak species sold here for the first time are resistant to global warming.

The species can be found here in the store: https://quercus.guru/shop/.

What would we have there?

Different types

Well, for example Quercus michauxi. This species grows up to 30 meters high. This species is rarely used commercially. It occurs from Indiana and Illinois to Texas and Floria.

Quercus virginiana (Virginia oak or live oak): This species is almost evergreen. It is also found in Mexico and grows up to 35 (!) meters tall. The live oak is the symbol of the state of Georgia.

Quercus texana is considered a fast-growing oak. It likes nutrient-rich soils and is very hardy (good street tree). It grows frequently in Mississippi, Alabama, Tennessee and Texas.

Quercus velutina can grow up to 40 meters high. It is often found in Georgia, South and North Carolina and frequently grows on dry slopes.

Quercus hemispherica belongs to the red oak sector of oaks. It is also found in Mexico and loves sandy locations.

Quercus laurifolia grows from Texas to Florida and Virgina. It is robust and can withstand temperatures of over 40 and -26 degrees.

Quercus polymorpha is also found in Mexico, Guatemala and Honduras. The Mexican white oak is native to the state of Texas in the USA and is correspondingly resistant to heat and drought. It usually develops into a fairly small tree here. It is also known as the Monterey Oak.

Quercus shumardii is one of the largest oaks in the red oak group. The tree grows to a height of over 20m. The location should be sunny and the soil moist, loose, well-drained and rather acidic. It is considered to be very drought-resistant.

Quercus lyrata x Quercus nigra is also known as “Compton oak”.

Some acorns are not quite cheap. However, we currently have a voucher promotion for purchases of 50 euros or more. Please enter “klimaschutz” to receive the discount.

Oaklovers – Quercus international. There is a new group on Facebook – “Oaklovers – Quercus international”. You can join here:

Hobby and exchange in Oaklovers – Quercus international

Growing oak trees is a wonderful hobby. It decelerates, it calms, it grounds. And it helps us humans to create something meaningful, to realize that we can be a productive part of the whole. And of course, even if it is actually a classic “solitary hobby”, it makes sense to talk about the specimens of the genus “Quercus” from time to time. After all, there are around 600 Quercus species.

An exchange is now possible on Facebook (see above). Which species could this be? What general conditions need to be considered for different species? Where can you get good seed? Who might swap acorns? Which species can be discovered in which botanical garden? There is a lot to discuss.

Quercus-related species from the beech family (Fagacea) can also be discussed. By the way, from time to time small acorn shipments are raffled off among the members of the group. So it makes sense to actively participate in the group.

Of course you will also find dates here, e.g. dates for https://www.internationaloaksociety.org/. Or also information on special oak species for sale, e.g. here: https://quercus.guru/shop/.

Small competitions are also held from time to time: e.g. “Who sends the ‘most beautiful’ oak photo?”, or: “Who knows a particularly spectacular oak species?” etc.

Meaningfulness

You can also explain your motivations there. Why do you grow oak trees? What significance does it have for you? Do you want to do something for nature conservation or climate protection? What is the core of your enthusiasm for oaks?

Planting oak trees is a wonderful hobby. It’s a joy to see the little acorns sprout, to accompany the tender little plants, to nurture and care for them. One day they will grow up and grow old. They will outlive us and we will be able to leave something meaningful to the world.

Several oak species can live for well over 500 years, they provide food for many wild animals, they cool the environment, they can contribute to combating global warming. They provide life and can accompany us for a lifetime.

There is a lot to consider. The quality of the seed, the soil, the method of planting, liming, acidification, protection against too much water (or too little). It is a wonderful task to create and do something for the environment.

DocKalle Oak species from California

27.7.2024: Oak species from California

Acorns and oak species from California

The first species for this year have been selected. In winter 2024, oak species come from California (in the form of acorns). E.g. Quercus lobata (Californian white oak), Quercus x jolonensis and Quercus douglasii (blue oak). This year also: Quercus kellogii (California black oak), Quercus wislizeni and Quercus chrysolepis (canyon oak). After a long, long search I finally managed to find someone who sends acorns of Quercus tomentella from California, but only a very limited number (100 pieces). Oak species from California are special because they are very well adapted to a warming climate. Quercus tomentella is a rarity that is difficult to obtain (see https://en.wikipe dia.org/wiki/Quercus_tomentella). This species originally only occurs on the Channel Islands off California and on “Guadelaupe Island”. This species is highly endangered. It forms hybrids with Querrcus chrysolepis. Quercus tomentella is also known as the island oak. The acorns will probably arrive here at the end of February/March 2025. Quercus kellogii can reach heights of up to 35 meters.
It can be found as far as the border with Mexico.
It grows on slopes at altitudes between 300 and 2400 meters.
It prefers drier soils.

DocKalle Sheep's wool

Oak growth through sheep’s wool

Many oak species are grown here using sheep’s wool. Oak growth through sheep’s wool is impressive. Even Quercus dentata and Quercus suber grow excellently due to the phosphates in the wool.
We currently have 32 sheep and goats living on the farm. They provide peace and quiet in hectic everyday life, graze on wildflower meadows and enjoy the summer.
More of the four-legged friends were clipped today so that they can get through the year well, it can still be scorching hot.

Soil substrates for growing oak trees

Several repotted oaks, Quercus pyrenaica, Quercus suber, Quercus frainetto, Quercus macrocarpa, Quercus acerifolia, Quercus dentata, all benefit from oak growth through sheep wool. If they are large, they should help to cool the planet.
There is a lot of experimentation with soil substrates here. Sandy soil, loamy soil, lime substrate, sheep’s wool (retains moisture) and provides phosphates, coffee powder (makes the soil acidic) and well-seasoned horse manure.
Sometimes also chicken and duck manure, pig manure, etc.
It is so interesting how you can influence the growth of rare oak species. A science in itself. I’ll write a book about it one day. It is grounding (in the truest sense of the word) to have this hobby. You deal with the essential things of existence. How can life thrive, how do trees grow, what can be done to promote rare oak species? I’m always delighted when seedlings have grown a bit bigger again after a year.
And people peer curiously out of the poke baskets. These are now bursting at the seams 🙂

Soil substrates are available free of charge on request.

16.06.2024: Mexican oak species

Mexican oak species

The work at the oak nursery is wonderful. It is grounding (in the truest sense of the word), it decelerates, and it is an absolute privilege to “work” with oak species, some of which have become very rare, and which sometimes only exist in small
corners of the world. Fortunately, there are many, many collectors all over the world, and we use the proceeds to finance part of our animal and species protection measures.
In the pictures you can see many Mexican oak species. The leaves look very different from those of oaks, but they are still Quercus specimens. Here you can see, for example: Quercus depressa, Quercus jolonensis (USA), Quercus hypoxantha, Quercus douglasii (USA), Quercus hypoleucoides, Quercus aff. miqhuihuanensis, Quercus sinuata var breviloba.

Animal company

You always have a lot of company when working at the oak breeding station. The storks rattle and rumble, it won’t be long before the two young storks fly out.
Right next to the oak station is our infirmary for our poultry. We currently have some ducks and chickens (along with their husbands/wives) here due to various fox attacks. Some were seriously injured and are treated 2 to 3 times a day.
They are slowly recovering and will fortunately survive the fox attacks.
Ducks in particular are very social animals (similar to geese),
that their partners need in everyday life, which is why they are treated here as a group. Two young ducks hatched by a wild duck are very funny (and fortunately unharmed).
One of the ducks appears to be a hybrid between a dwarf duck and a wild duck. The two tiny creatures do everything together and entertained me very well during the oak treatment today 🙂

Unfortunately, the foxes have taken various animals from the forest (the place is teeming with fox dens). Unfortunately, that’s part of it. It is impossible to completely fence off the 4 hectares of grace farm land from foxes and the puppies are also hungry.
Next to the infirmary (hermetically fenced) and the oak ward are some flowering meadows that we have planted. The meadow daisy is currently in bloom, as are St. John’s wort, meadow knapweed and meadow bedstraw.
Sheep and goats graze there on separate areas in the sense of staggered mowing. After mowing, they move on to other areas. On the claws and in the fur: seeds. In this way, they played cab for biodiversity.
And this is also wonderfully relaxing and alleviates the everyday hassle of “normal work” in the office.

Promoting diversity

Ok, Mexican oak species are not necessarily a benefit for the native fauna, but it still makes sense to preserve, nurture and care for these species too. Just like many other oak species from all over the world.
