Each spring I have been adding bagged garden soil to my raised beds. This is to replace soil lost when pulling up plants at the end of the growing season. Will masonry sand work for a garden mixed in with the existing garden soil? I add fertilizer early each spring to the raised beds also. I know masonry sand is good for lawns, but I do not know about a garden.

it’s fine and helps with drainage. It is generally sterile and free of weed seeds also

"Sand" is a size classification...sand...silt...clay. Masonry sand has sharp angles on each grain, so it binds hard in mortars. River sand has rounded edges that makes a poor bond in mortar. The only thing about sand for the yard and garden is that it be weed seed free. River sand costs less but often has seeds Unfortunately, what garden centers sell you could be anything. Buy masonry sand from a concrete supplier.

I have been getting my sand from a wholesaler for $33 a ton.

If you order Bed Mix from most nurseries, it’s mulch and sand mixture.

Masonry sand will work, but it has no organic matter in it. I would also include some peat or other composted material in with the mix,

It will be mixed in with new garden soil and old garden soil.

If you have very poor drainage then masonry sand can help but in a good garden soil mix , which generally has some sand in it, it won't do anything to help your soil and likely is hurting as masonry sand has no organic benefit. Why are you wanting to add sand rather than a good compost or more garden soil? If I were adding sand it would be Lava sand which has many organic nutrients.

The no dig garden proponents would have you cutting off the plants and letting the roots decompose in place. They would also just replace any lost soil level with compost.
