Need soil advice to start a garden on sand
Comments (13)Please forgive this long rambling post. I obviously don't know what I'm talking about, really, but think of it as a sympathetic brainstorming post. Organic material won't turn a beach to gold, but it provides the water retention and nutrients in one product. Most people raising vegetables concentrate on the top six inches of soil because vegetables have relatively shallow root systems being annual type things. Most of the soil food web is happening in this top inches where the oxygen is, as well. The question is, if you do put down 6 inches of topsoil over two feet of sand, how long will the topsoil stay there? You need somebody who's actually done it to say yay or nay. I don't have any experience with how fast pure clay would wash down into two feet of pure sand. I'm thinking on this question in light of my own experience, though, and I know clay doesn't wash down through pine fines mulch. Clay tends to stick to organic material, even when one is sorry that one poured the muddy bucket of water on one's mulched front beds and tries to wash it off with a hose. Another thing to consider is that you won't get clay loam in any bag labeled topsoil. Those bags have always contained half decomposed pines fines mixed with a goodly amount of sand around here. Now, this is good advice anywhere--LOOK at anything someone is calling topsoil before you buy it. Don't be paying somebody for topsoil if you're getting pine fines and more sand. I know a daylily grower once said he grew his daylilies in pine fines--that's why I got them as a mulch. Around here they are sold in bags labeled "soil conditioner." Some of my bags still looked like fine pine mulch, and some were more decomposed to a compost looking stuff. Maybe you could remove some sand and put down a layer of pine fines under whatever topsoil you get. Being wood, they wouldn't disappear as quickly as a more finished compost, and I bet they would help hold onto any clay-type topsoil you brought in. True, pine fines might suck up a bit of nitrogen as they decompose, but you could watch your plants and give them an extra bit of bonemeal or something if they seem to need a boost. The fruit tree idea is what has me raising my eyebrows. I'm not sure something as big and demanding as a fruit tree will grow in several feet of sand no matter what's put in the top foot of soil. The great thing is, you can experiment yourself. It's not the end of the world if a fruit tree dies on you, and if it does well you can come back here and tell us about it!...See MoreNeed advice on soil additives for new rock garden
Comments (9)Pudge, Actually, it's kind of a funny but it's unlikely that most of the rocks you're seeing are really "from" your area. Most of the rocks we see at surface on the prairies were actually transported from large distances away by the movements of the glaciers... (Same where I grew up in central Sask... strange that one would become a geologist in the relative absence of rocks! Or of outcrops, at least!) I believe the nearest outcrops of in-situ bedrock (i.e. older than glacial age; exposed at the surface) would be up along the Hanson Lake Road area, approaching The Pas, and in the Shield area to the east and southeast, and in the Cypress Hills to the west...(I'll have to check this, against a map of Saskatchewan geology, though, to be sure that there isn't some pre-glacial strata outcropping in the river valleys in the area.) So, anyway, the rocks you see in the fields, and in the young glacial deposits that are dug up as gravel pits (after being eroded/transported and weathered down into gravel), were generally transported by glacial action, generally from the Shield area. So, the rocks you see are likely to be a mix of sedimentary, volcanic and metamorphic, since they were picked up across the vast terrain along which the glaciers moved. Yes, it's very likely that some of your rocks are granite or other volcanics, others are metamorphic (schist, gneiss), some are sedimentary (limestone, sandstone); the quartz cobbles or boulders could have had a variety of origins (may have been weathered out of very-coarsely crystalline volcanic rock, or from fracture-filling; or sedimentary from fillings of cavities, or metamorphic from recrystallization of sandstone). The sparkly ones may be schist, a metamorphic rock containing abundant flat, shiny crystals (biotite and muscovite) that are all aligned by heat and pressure and folding. Anyway, that may be a little more than you wanted to know, LOL! Sorry, I can't think of a good website offhand for rock ID but I'll think about it and ask at work......See MoreNeed soil advice to start a garden on sand
Comments (6)It's a good idea to build raised beds for vegetables and you can amend the soil within the beds (25% amendment to 75% native sand). The raised bed should be at least a foot high from ground level and a foot deep. Better yet, make it two feet deep into the native soil. if you really want to spend some money, dig 2 feet deep, put a 12-inch walled raised bed on top of that and fill the now 3-feet-deep pit with bulk "potting soil" (from a good landscape supply company). Never bring in "fill" to top off native soil, no matter how good one thinks the topsoil is. It creates interfacial tension (drainage becomes weird). When it comes to trees, it's always best to work with native soil without amendment. 6 inches of anything on top ain't gonna make a deep-rooted tree happy. Most trees are happy on sand. Citrus and stone fruits will require extra watering and feeding but the sand will be fine. By the way, "beachsand" is soil. And it drains well and it's easy to dig. Lucky you.

Comments (38)when people say mulch... I think it makes a difference in what you mulch with..... here is link to one of threads where I had the same problem..... https://www.houzz.com/discussions/4122019/soil-is-starting-to-she-water-help#n=10 My soil was shedding the water... I am in Florida and have major sand.... when I started my rose garden I dug down 4 feet deep and filled it with horse manure and let it decompose.... then I planted in my nice new soil. I mulched my roses with red much..... however, as that wood started to break down it created a crust on top of the soil.... it and the sand kept my roses from getting water...... I ended up buying some good top soil.... hauled in more horse manure and topped off the garden.... and EVERY year I now use mulch from my own banyan tree leaves that I chop up with a Sun Joe.... My soil seems to now hold water better... however, I what seems to baffle me is WHERE does the soil and mulch go.... after all of the things I have done.... I am still getting sand..... It is alot of work to keep adding dirt and mulch, and I don't think I am building up the soil.... just keeping even because if I stop I am back to sand....See Morechristi1996
