Landscaper planted a columnar oak next to our house a year ago and it has struggled in our clay soil. It has developed a distinct lean to one side despite being staked. About half of it has leafed out but the other half appears dead. Is there any hope of pulling it back into vertical or is it a lost cause given our soil? There are two main trunks that are intertwined and both have leaves.

Hello,
It sounds like your columnar oak is experiencing some stress, likely due to the clay soil conditions. While clay soil can be challenging for trees because of its poor drainage and dense nature, there are steps you can take to help your tree.
Here are some suggestions based on the information provided:
Soil Improvement: Amend the clay soil with organic matter to improve drainage and aeration. This can include adding compost, shredded leaves, or other organic materials to the soil around your tree.
Pruning: Since you mentioned that the tree has two main intertwined trunks, consider pruning to remove any dead or diseased branches. This can help redistribute the tree’s energy to the healthier parts.
Staking: If the tree is leaning, you may need to adjust or add additional stakes to provide support. Make sure the stakes are not too tight and allow some movement for the tree to develop stronger roots.
Watering: Ensure that the tree is getting adequate water, especially during dry periods. However, be cautious not to overwater, as this can exacerbate issues in clay soil.
Consultation: Since the tree is showing signs of struggle, it might be beneficial to consult with a local arborist. Consult with a certified arborist onsite. (Arborist comes to your site)

It’s not necessarily a lost cause, but it will require some attention and care to help your columnar oak thrive. Remember, improving the soil and providing proper support can go a long way in helping your tree recover.
I hope this helps!
