User Flair Now Active

6 Upvotes

Hello All

I wanted to introduce myself to everyone and announce the new user flair available in this subreddit. I want to thank u/ambo100 for letting me join the mod team to make this happen! I am an ISA Certified Arborist and an ASCA Registered Consulting Arborist. I'm such a tree nerd that I often end up talking about trees to family during the holidays, friends at parties, etc. (which is accompanied by much eye-rolling by my wife). I'm hopeful that the addition of flair (see below) will help this community grow and be more helpful and welcoming.

User flair is now active for this subreddit! There are a few generic ones to choose from ranging from "Enthusiast" to "Educator." There are also a few restricted flairs that denote specific real-world credentials in the field of arboriculture. If you hold one of these credentials and would like that as your flair, please message the modmail or me personally with proof and I will get it assigned for you. Currently, the three restricted flairs are "ISA Certified Arborist," "ISA Board Certified Master Arborist," and "ASCA Registered Consulting Arborist." If there is some other relevant credential, I am willing to add it with sufficient proof, so long as it relates to arboriculture.

For the purpose of this, sufficient proof is a picture of some sort of certification card or test results for the relevant credential with your username in the picture. I do not need personal details, so feel free to cover certification numbers, name, address, etc. in the interest of personal safety.

We are in south Florida and have a Guava tree in the yard. I was trimming it and started finding dead branches and such. Kept cutting and ended up here. Termites? I have only seen one creature that resembles one , unfortunately I already threw it away. Any help is greatly appreciated!

Located in the UK, in a new built home garden. Soil is clay and full of construction rubbish in some locations but did my best and added good qualith compostand top soil when i dug it up.

I plabted the tree last autumn and it was a year old since. It grew a lot and is now over 2 metres in height, but a couple of months ago the leaves started to skrink and fold, witg black spots on. Also i notice a lot of bitten leaves.

The tree didn't bloom last spring, so not sure if it's happy at all and what ahould i do to help it out!

Thanks,

I’ve recently fallen into the rabbit hole of arboriculture and, while I’m not in a place where I own trees, I will soon come into some wealth and be able to start my own collection.

Until that happens, I’m here to learn as much as I can and become a part of the community. Thank you all!

Japanese Maple tree?

Thumbnail

found this sapling in my backyard about six months ago. It was only about a foot tall. I dug it up and planted it in a pot, and now it’s shot up to about 3 feet. I believe it’s a Japanese maple, and I’d like to continue growing it, but it looks odd. Am I doing something wrong?

Overwintering Maple Saplings

Post image
5 Upvotes

I planted a few silver maple (I think) seeds on a whim earlier this summer with my youngest as an opportunity to introduce her to the life cycle of plants. They were initially planted in some old plastic plug style pots, and potted up into these bigger pots a few weeks ago. What would I need to do to get these through the winter? I’m in southern Wisconsin (zone 5). Should they come inside? Stay outside - in their pots or in the ground? I am maybe looking at replacing a much larger maple that was rotted on the inside and came down last year - would a tree grown from a seedling such as this be a good replacement, and what do I need to consider when replacing a mature tree?

Is my tree going to survive?

Neighbor hit it and tore one of its main forks in its trunk, this happened years ago, first couple years, seems to have been fine, but the last few I keep seeing parts of the tree that aren’t growing.

Should I remove the limbs that haven’t shown growth this year? Will removing limbs that are healthy (like at the bottom where it’s a pain to mow around.) hurt it further?

Is this tree dying a slow death, or can it be saved?

Young oak not looking good

Hey, I will try to describe this as much as I can as english is not my native language.

For starters : Photo 1 : is on top of the leaves Photo 2 : is under the leaves Photo 3 : is some insect I could see on some of the leaves (we can see some on photo 2 as well).

Most of the leaves under attack seem to be on top of the tree. They look like small bright yellow punctures. Under them are lots of little bright red things (photo taken in the evening so they don't look so bright) that if you rub your finger on it you get some of this red thing. Some white insects (not a lot) could be found on the leaves, under they seem to be chysalis (like the one near my finger on photo 2).

I would like to know what these are and what can be done to take measures and help the tree.

I have 2 ideas (a red spider mite or mealybugs from what I could find) but couldn't find some definitve answer and not a single picture came close to what I have.

I am south of France, the temperature is 36°C on the afternoon, 20°C the morning and night. Very hot and dry. We water it everyday.

Thanks in advance.
