raised bed soil question
Comments (4)Definitely leave it. Not only is it organic matter, it is the best sort of organic matter possible. The interface between roots and the soil microbes (bacteria, fungi, nematodes, etc) is one of the great mysteries of the plant world. There is such a strong symbiosis, it's kind of hard to tell where the plant ends and the soil begins. Plants give away about 30% of the sugars they make with photosynthesis. Who do they give it to? The fungi & bacteria...who give them the nutrients they need, nitrogen & other elements. They both need each other. The whole point of adding organic matter is mostly to feed the microbes... well, they're already there in those roots. It is theorized that it was fungi and bacteria who first colonized land and broke down minerals to make a hospital world for plants to come out of the oceans. So... here you have roots surrounded by a rich community of beneficial microbes exactly where you want them, where the roots of your next crop will be growing in short order. The decaying organic matter will also attract worms. Leave the roots in place, at most double dig the beds. Try to avoid mixing the layers too much (disturbing soil horizons)....See MoreQuestions re: raised bed soil + composting/fertilizing
Comments (15)While many tell you that you need something called "topsoil" they also fail to tell you what they mean by "topsoil". "Topsoil" is defined as the top 4 to 6 inches of soil from someplace and it may be something worth using or it most likely will not be. Many of those I talk with think "topsoil" and loam are the same thing, they are not. An ideal garden soil would be a mixture of about 95 percent mineral (the sand, silt, and clay particles) and about 5 percent organic matter. If you really could get about 50 percent organic matter mixed into the soil you could have a bog, a soil that holds too much water and causes plants to drown. The soil I have gardened in here for years is Lake Michigan beach sand and even by adding what some consider extremely large amounts of organic matter I have not been able to get the level of OM in the soil above about 8 percent, and that has been ideal. Plants evolved eons ago getting nutrients from the Soil Food Web, those wee critters that convert organic matter into something plants can use. Dumping fertilizer onto soil to feed plants is something only about 200 years, or so, old, much too new to really do the job of feeding plants since they have not adapted yet. Feed the soil and the soil will feed the plants. Mel's Mix is basically a soilless potting mix and it needs a lot of perlite, or vermiculite, to provide proper drainage because it is all organic matter and would tend to hold moisture too well. kimmq is kimmsr....See MoreRaised bed soil question for Central NJ
Comments (5)I have never been impressed with the bagged topsoil or compost from the big box stores. Read the ingredients panel (on the back, near the bottom, usually) and see what "may" be included; pretty vague. There are some brands carried by nurseries that are better. I checked out a bag of commercial "raised bed mix" today and found it "may contain" topsoil, composted manure, peat moss, coir, etc. All these are fine, but by the soft feel of the contents and light weight of the bag, I suspect there's a good deal of peat moss in there. Peat moss is not a great amendment for the garden for several reasons, which I won't delve into here. Loose topsoil, compost, or mushroom compost from a reputable nursery is great, if you have a way to transport it, or need enough to warrant delivery, which you will pay for. You can always mix up your own if you have home-made compost and topsoil. Roses and perennials are a long-term investment - they take a while to get established - usually three years to really get going ("first year they sleep, second they creep, third they leap" is the old saying) so it is worth the effort to prepare the bed well the first time around. Annuals are just here for the one season, so if you don't get it right the first season, you can always fix it the next....See MoreRaised bed soil question
Comments (11)Most folks don't have piles of excess garden soil sitting around waiting to fill a raised bed so bringing in/importing soil is extremely common. There is nothing wrong with a screened topsoil provided it has been screened adequately enough to remove larger rocks (large than 1" diameter), big roots or chunks of wood and any other sort of debris - plastic, pieces of metal, etc. And I'd go with the leaf compost at a 25-75% ratio to start. That's higher than OM levels are suggested for inground soil but it will help to both improve drainage and retain moisture in the raised beds. Sounds contradictory but the two conditions really are compatible and that combination very desirable. It'll hit the suggested level soon enough with continued decomposition. Lightly tilling the first few inches of the underlying existing soil is always a good idea but only if already bare of any lawn grasses and free of most of the weeds. If not, layer sheets of overlapping cardboard down first to smother and kill off whatever is growing there. By the end of the season the cardboard will have decomposed and plant roots will have started to disturb and penetrate the ground soil. Pay attention to your plant needs during the season as you may need to supplement with a fertilizer. A compost comprised only of leaves will not have the range of nutrients as a mixed ingredient compost would and neither can be relied on as a complete and adequate nutrient source....See Moregardengal48 (PNW Z8/9)
