Actually, if it isn't too late.... I think the catsup in it would burn... it has sugar in it. what I would do, if you have a metal meatloaf pan, if not, take an aluminum pan, or just some layers of foil, make a meatloaf out of it and cook it on med heat/indirect heat. Not sure if you have gas or charcoal grill. I think the indirect heat would cook it really well, and have a bit of a smokey taste to it. I have grilled turkeys and chickens and even prime rib roast this way. (indirect heat.) give is a unique and really good flavor. completely diffent than cooking in oven. The other thing you can do, is if you have an electric skillet you can make the meatloaf in it that way.

how to plant...: https://sites.google.com/site/tnarboretum/Home/planting-a-tree-or-shrub i figured it was a builder deal ... based on looking seep into the pic .. as to my pic ... i had a kids pool to the left.. i wnated to sit under the tree.. in the shade ... hence the pruning ... its now about 10 years later. ... and the bottom branches.. are about 3 feet from the ground.. the major part of the branches did not go down.. but the branchlets off such.. did .. the bottom line.. how i remember it... roots like to be cool and moist.. to do their job... bark is meant to be DRY ... by putting park underground.. you will rot it ... and the vascular system of the tree... the cambian layer.. is just below that bark ... rot the bark ... kill the tree ... dig down.. give us a few pics... maybe we can come up with some ideas ... like an wall of one or two or 3 retaining blocks.... to hold the soil back ... there has to be a term for that.. but its escaping me.. to google you a pic ... ken

As pip hints....now is a great time to feed! Also, almost all knowledgeable avo growers use mulch. It is beneficial in many ways...including keeping the weeds at bay. This time of year avocado trees can look a little rough....especially because of drought/lack of water. Don't fret about the cardboard...I am sure you will be fine.

I think it's an appropriate amount when fertilizing young seedlings for the first time. It's always better to err on the side of a light touch at first with young seedlings, IMO. Especially in tiny seedling pots. Fertilizing at full strength is better when you have a bigger container or the plants are in the ground unless one has a ton of experience with a very specific setup and a lot of experience with the exact growing mix and exact fertilizer and therefore can predict exactly what will happen.
