Wasn't this already discussed here? https://www.houzz.com/discussions/lemon-tree-losing-green-leaves-dsvw-vd~5607649?n=137 

I agree, as a general rule feed it and let citrus take care of itself, this means no thinning, no pruning, and removing the support stake as soon as possibly. With grafted citrus you do need to keep an eye out for root stock shoots growing from below the graft and remove them as they show up. All of those rules for deciduous fruit (stone fruit, etc.) does not apply to citrus. Young citrus may have some long lanky growth, but will tend to sort itself out over time, citrus needs to bend in the wind to gain strength and is far more flexible than other types of fruit trees so there is little concern of wood splitting in a healthy citrus tree. About the only time you should prune is if a limb is touching the ground. Citrus forms a closed canopy, you DO NOT want an open airy tree structure in citrus like you would want in stone fruit.

Kelley that is great to see! How’s the Villafranca? Mike, I’m sorry I’ve been MIA...I’ve been busy with family stuff and not gone on the forum. I would recommend starting with the cleft graft that jay posted above. Some here (like Bob) are wizards at grafting. However, I think for the rest of us newbies the cleft graft is the easiest to execute. That guy makes it look much easier than it is. Good luck with it!

Bonnie, I did my very first graft last April and I’m up to 11 successful grafts so far lol. It’s definitely a disease, as Hershell Boyd describes it lol. There’s also something so rewarding and satisfying about growing a tree that you grafted. Welcome to the club, my friend! At 33, I think most young adults do not manage their priorities well at all (Pot AND Kettle, here). Personally, I would rather opt out on owning the latest and greatest technology/car/home/decor/etc, in order to maintain my hobbies. A day spent fly fishing on a remote mountain stream, or quick ride on my horse after work is much more rewarding than binge watching shows on a $1500 TV or playing games on a computer all night. I drive a reliable, 17 year old car, with no payment. In the mornings, I drink my coffee and walk amongst my unhealthy number of citrus and fig trees, and enjoy the fruits of my labor (hah!). Of course, to each their own, with no judgement from me. I simply choose to invest in my outdoor hobbies, which bring me great joy and even peace in this crazy, hectic life.
