What is the best way to fertilize trees?

[DRH1175]

Do those pound fertilizers spikes work or is there a better way?

If you hire someone, they'll do "deep root" feeding, where they put the fertilizer down into the root structure.

If you use spikes, make sure you put them in the drip line of the canopy of the tree, alot of people put then right next to the trunk, which doesn't do a whole lot.

I use the Stakes and pound them in about 2-3 feet from the trunk.

Thats what JOBES instructions said to do.

If its a bigger tree you might need to get a bit further away

I use the spikes on my orange trees, usually put one on each side near the drip and push them down with a piece of wood rather than using the pounding cap on them as it does sometimes break the spike. Since using them the last 4 years i have had oranges every year. Actually have golf ball size on now.

You can also use a granular fertilizer like a 14-14-14 from a landcape supply place and spread around the drip line. A product like this is rated for 1 lb per inch of trunk diameter.

I poke a bunch of holes in the mulch into the dirt and then pour it in. If you have more than a few tree's this is the more economical way of doing it over the spikes. I have over 20 trees on my property that I fertilize twice a year and I get by with $36 for 80 lbs of fertilizer.
