So I purchased an apple tree and a plum tree from a local vendor. The apple tree is about 5-6 feet tall right now and the plum tree is about 4-5. I have a long raised bed in my backyard where I want to plant them. The area gets lots of sun.

The raised bed is not yet filled with soil so my question is what kind of soil should I buy that would be good to plant them in? I've seen all purpose garden soil, vegetable and herb soil, raised bed soil. I don't know much about this at all, I'm learning as I go along lol. Any help is appreciated.

Unless your raised bed is about 15 ft tall, the soil won't matter for the fruit trees. Are you planning to plant something else in the area? If not, I wouldn't put anything special in the raised bed as it will not encourage the fruit trees to root deeply. Do you have a source for native soil? Cemeteries give away soil in our area.

Hi, thanks for the reply.

As you can see in the image, the potted part of the trees is about the same height as the height of the bed behind it.

There is some soil already in the bed but only about an inch or two and I wanted to bring it closer to the top of the stones.

As for other plants, i don't know, maybe an azalea or some sort of flowering bush. Should plants like that and fruit trees not be planted together?

So I plan to plant those two trees in the bed, in the soil already there, but what additional soil should I get to put on top to bring it closer to the top of the stones? As far as I know, there isn't anywhere around here to get native soil. I was mostly just looking towards nurseries or Lowe's to buy soil to fill the area.

Planting things under fruit trees is not a problem if you can still maintain the tree (prune, harvest, fertilize) with the plants under the trees. What I have discovered is that anything under my trees gets tramped because I am looking up, not down at them.

You can fill your planter with any soil you want but I am concerned about the narrowness of your planter box with a fence so close. Apple trees get big - even dwarf and semi-dwarf would be too big for that area. Are you planning to espalier them?
