Live oak fertilizer

At that size and age, can’t imagine fertilizing makes a difference. Definitely need to bring in an arborist or similar to diagnose the issue.

I have 17 60+yr old oaks in my yard.

All live oaks lose their leaves and grow the catkins this time of year so they look scraggly in the spring. Triple 8 or 13 would do fine for them, drill holes along the drip line about 4 or 5 feet apart and fill them up with fertilizer or simply use the jobo spikes in the same manner.

But as others have suggested a soil sample will tell you what it needs if it needs anything. They love acidic soils while most turf grasses don't so there's a balancing act you have to play.

How many jobo spikes? I like this idea seems simple enough. Going to give it a try. No idea how old this tree is but it is pretty old. I’d guess 50+

Plus Ironite! You need this mineral!

That’s all I use on all my trees.

In Slidell so kinda hard freeze. Really this tree has been struggling since I bought this lot. It’s got cement in it to prevent it from falling over and cover the open truck. We will see if it happens. It on a bayou so it gets some flooding periodically

I use the fertilizer spikes on my trees. And have had descent results. You would need a lot of spikes for 6' trunks. If you can find someone to do deep root feeding I would go that route
