oak

Hello All, In winter of 2023 I discovered this post oak growing on a steep incline at an old family farm. For context, the substrate is called chert and the family used to sell it by the dump truck load to the city to use for road bedding back in the 70s. The picture of the dormant tree was...

Anyone have any thoughts on what might be happening here? Noticed the bark splitting over the last couple months, seems to be more growth popping up low by the splits. This lower trunk used to be bare. Today I came out and saw this white, powdery growth at the base. We had a very hot summer...

Acquired from nursery late winter 2023 (August). About 60cm tall. 1.5cm in diameter. As buds opened, i cut it back to some good bones, severed a single coiling taproot up to the base, trimmed to balance some longer fine roots and potted in September 2023. Added some moss, expecting it to dry...

This oak is very weird, I germinate a lot of acorns, and most of them sprout by april, this guy sprouted in may, he really took his time. When he germinated I pulled him out and saw no taproot, there were fine roots coming out of both ends of the acorn, haven't really seen anything like that...

Finally got around to finishing up collecting and potting up my acorns. Probably have about 100-150 total…which is way too many for my tiny garden, but 🤷‍♂️. So far I have: Texas Live Oak (Quercus fusiformis) Southern Live Oak (Quercus virginiana) Overcup Oak (Quercus lyrata) Shumard Oak...

Found this bad boy at Banat Village Museum in Timisoara, Romania. Gathered 10 acorns and planted them in a grow bag with old bonsai soil and some compost from the garden. I’m curious how many will sprout.

Post your entries in this thread (i.e. pictures of your acorns to signify that you're officially joining the contest). Start with any number of acorns. Spend five years developing them as pre-bonsai. After five years, narrow it down to three trees. After ten years, in December of 2033, Select...

Hey all, So, a month and a half ago, I was given the opportunity from a friend in the construction business to collect some trees from an area that was being closed off and cleared, next to a neighborhood in South Dallas. He knows I like to collect trees and practice bonsai, so he told me that...

This oak is about 1-2 years old now. It was collected last summer by my partner as a gift to celebrate the start of our relationship so the tree has a lot of meaning to me. My grandpa watered it but watered the leaves too and they all burnt off. I’m keeping it in the shade and cut the dead...

June 2023 pic. Has ramified a little more this spring.

I recently got back from a trip out to Texas hill country, which is always nice. While out there, we got the chance to visit Hill Country State Natural Area, a beautiful state preserve that had loads of hiking and horseback riding trails. While out on a hike I came across a dwarf post oak. Now...

I've been looking around at the Coast Live Oaks in my area and after seeing some of the stuff that @BrianBay9 and @Wulfskaar were doing I figured it was time to start some of my own. This will definitely be a long term project so come back in 15 years and we'll see what I've got 🤣 I collected...

I am trying to find more info on bur oak and if they are worth giving a shot. I am somewhat limited in collection areas and it just so happens a little squirrel must have buried an acorn a year or two ago because I have a little bur oak popping up in my yard. My main question is are bur oaks...

Hello 👋 I purchased the pictured oak last summer. My intention is to chop it quite short as the trunk seems reasonable. As you can see there is no foliage toward the base: will the tree just die if I leave no foliage on the tree, or will it ‘back-bud’? And shoot out some new branches. Any...

this tree in my backyard has the best twisty branches. I’m pretty sure that the owner grafted one or two of branches because they’re a different bark and growth type but the way they grow is wild. One of the main trunks also snapped off during ice storm Urie last year and is a great asymmetric...

This was a nursery stock Oregon white oak I picked up in fall. It’s a deciduous oak, one of the only trees I have that still has its leaves. However the leaves are browning/ yellowing. I haven’t done anything to it besides slip pot it into an airpot that was the next size up. with the same...

I know that Coast Live Oaks will keep its foliage during winter, but do they also continue to grow? I live in San Francisco, so our winters are very mild and will likely never reach freezing. If they do continue to grow, should I continue fertilization?

Curious if anyone has used these for bonsai subject or had any luck with them. I have one in my yard thinking of maybe getting some cuttings of or doing a possible air layer as I don't have any oaks and thought might be fun to play around with. Couldn't find much online about them as bonsai.

Dug up this oak a few months ago and it’s bursting with beautiful new foliage. Do you guys think this is suitable material for a good bonsai? Maybe if I chop it low and start a new leader? I dug it up because I thought the nebari was beautiful and there was a little taper at the base.

I’ve never seen bird poop damage a leaf (I’m 95% sure this is bird poop). So either this one was one helluva shot and hit this existing dead spot, or the bird poop damaged the leaf. Is the damage from a pathogen or possibly fertilizer burn from the poop (which I’ve never seen before)? The mold...

Hello everyone, I have been silent here for a long time. I am now back for some of your precious suggestions, please. I need to plan the next 2 years of the oak sapling I started in 2019 from a by-post nursery tree. The progression is shown below. I have been surprised by the growth of the trunk...

I have a number of oaks on my property and this particular oak was bent in half during an early season winter snow storm. It is quite a large tree and at the bend, it is probably 4 or 5 inches. It looks like it is healing at the bend and this is a pretty unusual thing to find. Would this...

Good Evening! I just wanted to share this new Oak! I got this from a family members property that has three different oak species, as well as other trees. This oak was carefully dug out of the ground and placed into a fairly large training box. I really like the way the trunk bends on it. the...

Here's my White Oak, or Quercus Alba, potted on 4/24/2021. It was from a nursery where it was grown from seed in a 80% pine-bark mixture. My goal for this tree is to thicken the trunk and develop the roots by repotting it in a larger, 5-gallon Rootmaker container with a more air-retentive...

Hi, I've been the arboricultural world for a few years now and I am studying to take my ISA certification. I figured I probably should try to keep a tree or two alive before doing so. So I bought a juniper, an azalea, and dug up this little live oak. When I collected the live oak it was buried...
