Sinking raised perennial/shrub beds
Comments (5)The difference between an artificial raised bed and the forest is that the forest adds organic matter at a slow rate, to the surface, and it takes years and years for an inch of additional topsoil to form. During that time it's also naturally eroding downhill when it rains. In your case, you added a lot more organic matter at once, and dug or tilled and mixed things up. This has the effect of fluffing the soil with air. It will settle a bit over time. In addition, the compost you add will continue to decompose. Only the mineral portion of soil will be permanent. It's fairly common for this to happen with new raised beds, and the effect is worse the more organic matter you used. I know there's another thread on this just in the last week or two, I'll try to find it....See MoreWill these perennials survive in raised bed?
Comments (6)shelli, if you add your location next to your zone in your i.d. line, people will be able to learn from and help you because they can relate to your experiences through theirs. i think the question you have is not are these plants zone hardy but are they hardy when planted in raised beds. 18" is not terribly high but i don't know the answer. i think there is some rule about plants surviving in raised planters or beds if they are 2? zones hardier than your zone. but i've been meaning to look that up for awhile myself. I can tell you that my sedum in a container 2' H- survived our z. 5 winter fine last yr. and my hakonechloa planted on the sloped walls of our 'chasm' also has survived for years. best, mindy www.cottonarboretum.com/...See MoreRaised Garden Bed Deep Enough for Perennials?
Comments (4)Ok, thanks for the feedback. This is the story behind the raised bed idea: I recently had bushes and a small tree removed and replaced with pine fencing. The bushes had been in place for 20+ years. The removal was cutting them to ground level but a lot of the roots remain. There was also ivy that I fought back all season this year. I poured mixtures of vinegar, ivy killer, salt, and dishwashing liquid into the soil. I now have the soil covered with weed barrier and mulch. I planned on putting the garden bed over this soil/barrier/mulch for a couple of reasons; I didn't want to have to battle thru the roots from the old bushes and I don't know if the soil is suitable after all the ivy killing stuff poured into it. It would be nice to plant directly into the ground just because it's so much cheaper. A raised garden bed project with soil can easily run hundreds of dollars. I would rather spend that on my flowers! The space that I'm planning on planting is full sun and receives direct afternoon sun, so drying out would be a problem. What do you think about the soil I'm working with?...See MoreIdeas for raised bed - annuals / perennials?
Comments (6)Hi floral_uk. The garden is SE facing, so the garden gets plenty of sun. ken_adrian Adrian MI cold Z5 Fortunately there have been no incidents nor any near misses so far. I would hope that plants up to around 2' high will give enough of a visual barrier that even the severely inebriated cannot fail to miss. And lets face it, if they do, they will be sufficiently anaesthetised against the pain that may be inflicted! Hopefully the stonework will look much better once I get the beds planted up and the patches swept and hosed down! In my other thread relating to the lower herb bed, I mentioned that I may move the herbs to pots. If I did that, what would be a good selection of plants for the upper and lower beds? Ideally id like a mix of annuals and perennials, but I must concede that I am not an expert so open to any and all advice!....See Moresailaa
