I’ve discussed my dislike of cardboard mulch before: like other sheet mulches it restricts water and gas transfer between the soil and atmosphere. In published comparison studies, other mulch choices generally outperform cardboard in terms of plant growth, weed control, etc. But there’s one area where cardboard is tops compared to every other mulch material … Continue reading Why I don’t like cardboard mulch
Planting annual displays is not (at all) my favorite gardening pastime, but we do some "color" around our events building and along the garden entrance to make the area pop during our busy season. Those of you who install institutional or commercial color beds are familiar with the process – yank out last season’s annuals/tulips/whatever, … Continue reading Are you a “before” or an “after” mulcher?
After Jeff’s recent eclectic musical selection of Rasputina’s 1816, I thought I’d go a little more mainstream with Lynard Skynard’s ‘Swamp music’. Turn it up and remember; if it’s too loud, you’re too old. http://www.youtube.com/watch?v=_wJWBcj7lsY So, what got me thinking about the swampy backwoods down South and the late, great Ronnie Van Zant? The arrival of … Continue reading Cypress mulch re-visited
A follow-up to Linda’s post about a recent study in Arboriculture and Urban Forestry that indicated mulch may not reduce evaporation of water from soil as we generally assume and which suggested that landscapers may want to re-evaluate their mulching practices. As Linda noted, we have some real concerns about this conclusion and believe that … Continue reading Mulch: Just Do It
We typically think of mulching landscape beds as a good thing. And it usually is; helping to conserve soil moisture, reducing soil temperatures and contributing to soil organic matter. Recently, however, I received an e-mail from a local landscaper that reported severe damage to annuals and perennials in a landscape bed immediately after applying hardwood … Continue reading Toxic mulch: When shredded bark goes bad
[Try to say post title three times fast. Heh.] Here on the GP blogski, we’ve discussed both the merits and shortcomings of many non-traditional forms of mulch; rather, stuff that covers the ground that is referred to as mulch. Shredded rubber, marble chips, lava stone, dyed lava stone (ick), etc. But this is a new … Continue reading Mulch much?
Alert reader Matt Wood pointed out a recent article in the NY Times on mulching with newspaper and wondered about my take on the topic. For use on landscapes, I do not like sheet mulches of any stripe. They tend to hinder to air and water movement, most especially in unmanaged landscapes like restoration sites. A classic … Continue reading Sheet mulching – benefit or barrier?
Almost a year ago I posted my complaints about rubber mulch (you can find the posting here). This week I was contacted by Jesse, a purveyor of rubber mulches. We’ve had a very civil discussion about the topic, and he asked me to review his fact sheet. Which leads me to today’s assignment. I have no … Continue reading Rubber mulch – the discussion continues
A few weeks ago I was in Olympia (it misses you Bert!) reviewing grant applications. As I tend to do whenever I have time and my camera, I set out in search of gardening goofs that evening. Here’s the edge of a relatively new commercial site I discovered: OK, not too bad so far. We’ve got a … Continue reading Why won’t landscapers use mulch?
Just back from a quick vacation to Little Cayman island. Truly a dot on the map – the whole island is about 7 miles long and a mile wide. Only 150 locals and a couple hundred tourists are on island at any one time. It’s beyond laid back, with few attractions other than the resident … Continue reading Pigmented Mulch in Paradise
