Should I remove this stump?

Other than planting the odd sappling I have no experience with trees and I’m in need of some advice if the community can oblige me. I have this tree on a plot of land near a canal. I noticed that it seems to have wood worm. The rest of the tree seems fine and healthy.

Should I remove the “offending” part or leave it be?

New build neighborhood…SW TX

Post image
5 Upvotes

We just purchased a home in a new build community.

We have two baby southern live oak trees. One near the house (see picture) and one in between the sidewalk and street.

Our concern is distance from the house and invasive root systems. I’m sure it will be decades before we have problems but I’d like to be proactive in avoiding them.

What trees would be a better option? We’re also looking to one tree to our back yard.

Advice for Reviving Yoshino Cherry Trees

Thumbnail

2 Upvotes

I recently moved into a home where my landlord planted two Yoshino cherry trees. They are quite young and, due to the extreme heat and lack of rain before I moved in, have begun to wilt and droop quite extremely. I think it would be a shame if they died, so I've decided to try to revive them. Is consistently watering them enough, or are there other steps I should be taking as well?

Crabapple

Long Island New York here, I'm a bonsai artist/instructor. I have been growing crab apples for decades, and I have a number of what we call pre-bonsai in the works. I always worry about getting enough hours of Winter Chill, and I'm usually rewarded with blooms and fruit. However this one threw me for a loop. Got fruit and flower at the same time. I did miss watering it one for 2 days and it was showing signs of drought stress, but recovered quickly any ideas why I might get a balloon july?

What is happening to my trees?

What could be going wrong here? These trees were planted in 2017, hardiness zone 6a, suburb of Chicago. I don’t actually know what type of tree they are…’picture this’ app has guessed Rocky Mountain Juniper or Eastern Red Cedar. Browning and needle loss seems to be starting from the inside out. I have 5 on my property with slightly different light and soils conditions - and all are struggling to different degrees of severity. I don’t think any are overly dry. If anything, the soil might be overly wet? Any idea what could be going on or how to save these trees?

We planted these trees about 2-3 years ago. Well we’ve been renting the house and when they moved out I realized the trees are now red… Is there any hope or are they goners?

Curious about Indonesian agriculture? Let's talk about tropical farming systems and crops! 🇮🇩🌱

1 Upvotes

Hi everyone! I'm Adis from Indonesia 🇮🇩

I recently graduated in Agronomy & Horticulture and I’m really passionate about tropical agriculture, especially in Southeast Asia. I’d love to connect with anyone who’s:

  • researching tropical crops (like chili, banana, cassava, or papaya)
  • working with smallholder farmers in Asia or Africa
  • studying organic or sustainable farming systems in hot/humid climates

Indonesia is a huge archipelago with diverse farming practices – from rice fields in Java, to dryland horticulture in Sumatra, to coffee plantations in Sulawesi. I’d love to share what I know and also learn from your perspectives!

If you’ve worked or traveled in Indonesia (or curious about it), I’d love to hear what you think about our agriculture systems, markets, or just the food 😄

Let’s connect, exchange ideas, and grow together 🌾🌍

Will my Monterey pine produce viable seeds if it's an isolated tree?

2 Upvotes

I have a Monterey pine in my garden and I'd love to grow some seedlings. Problem is, I'm in the UK and I'm pretty certain that there aren't any others nearby. Will the pine cones in my garden produce viable seeds?

Also if anyone has any tips for growing the seeds I'd love to hear them!

Thanks

Branch fell

Got home from work today and this branch had fallen. It wasn’t a heavy wind day and looks like it had some mold and rot. I noticed a few other weird things I hadn’t ever really payed attention to on the tree and I’m not sure if I should be worried about the rest of the tree dying and falling.

Little help with these green giants

Thumbnail

Bought these two weeks ago and it’s been hot here in souther Ohio (90ish). Using sprinklers to water every other day due to the heat.

They are a little scraggly but figured that’s from the heat and the stress on them being moved around.

Noticing this discoloration on the ends of the leaves a bit.

Is this just initial stress from everything? Or am I over or under watering these guys?

Thank you!

Bonsai Catalpa Dying Out!

Thumbnail

1 Upvotes

Help!

This is a new home we are landscaping with 3 gorgeous catalpa that are slowly dying out and will eventually need replacement. They’re stunning.

We want to continue this but are these a specific cultivar? Like an umbrella or the ‘Hiawatha 2’ which is a speciosa and Northern catalpa.

We have identified that they’re maturing and have lot of interior rot so preparing to add one and prune it in a similar fashion. How the heck were these pruned?? I can’t find anything relative to bonsai catalpa, I think I’m far off the track aside from this cultivar that looks very similar in canopy density.

I am located in the Midwestern part of the states- Zone 7a. Thank you for your time.

Can anyone help determine what is wrong with my tree?

I’ve lived in my home for five years and never had a problem with this tree until this spring/summer.

It usually has small pink blooms in the warmer months, but didn’t have any this year, and there is a white substance on the limbs.

I park next to it, and it seems to be leaving a thin, clear substance on my car is is sort of sticky to the touch, but it washes off easily.

I assume tit is diseased. Does anyone know what might be wrong and if/how it can be treated? Thanks in advance.
