The only plant from your short list that I could see your plan working with would be raspberries. And that is only because raspberries spread via rhizomes so they have to ability to adjust the depth of their new crowns by themselves (if their bed is increased in height gradually).

It is true that tomatoes root along their stems but that doesn't mean that they should be continuously buried to encourage more roots. Most people bury some of the stem when they plant out and leave it at that.

If the plants are small I would just dig up and replant. Wood chip wall would be similar to mulch, so best away from plant crowns. It would also steal nitrogen from the edge of the bed.

Pumpkins for example it is recommended to bury stems to increase root area....

I know many plants can have stems buried and they will root along that part, this includes many perennials and woody plants. Others will suffer crown rot. If I had to guess it would be which plants are easily rooted from stem cuttings, would also tolerate being buried.

I bury my tomatoes when I set them out. And it is recommended to hill dirt around potatoes. I saw an apple that topsoil had been piled against on one side develop fungus and the tree broke. The wood had a white cast to it on the inside surfaces where it split.

I know of a plan that I renamed to Treesdead from a similar name because when they graded the lots they buried the trunks some as much as 3 or 4 feet. Many of those trees died.

That looks like allot of “ extra “ work. I would just go with fabric pots “ air prune” which is the same concept as the video in the OP. I have over 50 varieties of trees, plants, veggies , berries etc...... growing in 5 to 25 gallon fabric pots. This is just my 2 cents worth . Good luck with your project which ever way you choose to plant them . Happy planting !!

Tomatoes grow adventitious roots along the stem that is buried. Most other plants do not do that and will suffer if the trunk/stem is buried. You'd better off building raised beds after your annual vegetables are done growing and you pull them out.

John D, what is the value of posting tomato and potato hilling up with an apple tree? Hilling potatoes, with something, is a must, not a recommendation, unless you want to eat green shouldered poison produce. The thread is about raised beds arounds different plants. Maybe I am missing something but I am not familiar with people planting apple trees in raised bed. Just curious.

Read the title of the thread. It's:

"building a raised bed around diff plants, what determines if its ok?"

You can build the soil up around any Brassicas ie kale, cabbege etc. They have the ability to produce new roots from the stems. I don't know if you grow currants or gooseberriesbut they are also quite happy to have soil raised around them. They'll root into it.

Thanks everyone.

Richard, or anyone else, because grapes are also a "vine" do you think it would be ok? Thanks.

Is there some reason why you want to do this? There might be a better solution.

JXBrown,

I suppose I could find another solution but adding a raised bed around preexisting plants in the area is preferred. The other day I did try to remove the grape vine but it was so rooted into the ground already that I don't think i would be able to move it to another spot without completely tearing up the roots.

Well, there's a lot of gardening experience here. If you want to share your problem, you might get some good suggestions. We can certainly help you with suggestions for transplanting your grape this winter.

Seasonal plants that can grow additional roots from stems or nodes, like tomatoes, can benefit from getting trunks buried in more soil. Add more soil, and the stem just makes more roots up where the trunk has been buried with dirt.

Trees that depends on surface roots for whatever additional nutrition, water, may have already grown those roots at that level it needed to be at. Put additional soil on top of that, and you now have surface roots that are deeper than they should be, which can harm the tree.

Now of course, some areas where seasonal plants don't necessarily die back, such as parts of California, a plant can benefit from having a lot more roots and root feeders, and continue doing well year after year. But in this case, it still acts like its seasonal counter-part of creating new roots at stems or nodes that are covered with dirt.
