Landscape fabric: should I use it in my garden?

IMG_3887

I’m not keen on putting landscape fabric beneath mulch in a garden bed, but the whole situation is significantly worsened when aliens beam up the mulch in the middle of the night.

Or whatever happened here.

Can you imagine what is going on – or more, accurately not going on – in the soil under there?  Blurrrrgh.  One way to promote soil health and support all the life in it is to ditch the landscape fabric.  (You can of course keep the mulch if you can find out which galaxy it ended up in).

I know…weeds!  The mulch – sans landscape fabric – will help out a bit with that. And if some weeds show up anyway, isn’t it true that we all need a slow, meditative weeding session a couple of times a week?  That’s when I get all my best thinking done…. ♥

Pest to watch (out for): Artillery fungus.

Hopefully no one out there is currently plagued with this pest – if you are, you’re in for some additional spring cleaning duties.  It’s a messy one!

Also called shotgun fungus, these members of the genus Sphaerobolus are usually spotted (yes, I’m making bad puns again) covering the sidings of houses or the exteriors of vehicles.  Artillery fungus colonizes wood, so if you’re laying down wood mulch, you may be encouraging its growth.  The peridioles (spore packets) of Sphaerobolus are interesting:  they rest above cup-shaped cells that gradually fill with water.  Eventually, the cells invert, which causes the peridioles to burst, exploding outward in a distance up to 6 metres (almost 20 feet).  The spores immediately adhere to any surface situated in the blast zone…which most often happens to be cars and houses.

Just to make things more delightful, artillery fungus is really, REALLY difficult to remove.  Part of the problem is that you don’t want to use harsh chemicals or scrapers on the surfaces that the fungus sticks to.  This website has a few potentially workable suggestions, the most notable of which is employing a combination of Mr. Clean Magic Erasers and a bit of mouthwash.  Bleach and hot water and plenty of elbow grease apparently works as well.  Definitely test a small area of before you start your cleaning project, as you don’t want to ruin any painted surfaces.

As for prevention of further attacks, it should be noted that there isn’t really an effective fungicide on the market to deal with artillery fungus.  (I’m not particularly fond of chemicals, so I probably wouldn’t recommend one even if such a thing was available). The best option is to consider whether or not you really need wood mulch, especially near the foundation of the house or alongside the driveway.  Replacing the wood mulch with gravel or another desireable product may be a simple solution to a labour-intensive problem.  As well, bear in mind that the wood chunks found in potting soil might also be a haven for the fungus.  (Don’t get me started on the LOGS I keep finding in commercial brands of potting soil mixes – it’s a pet peeve of mine.  I’m currently on a seemingly unending quest to find a good quality brand of potting soil – I thought it would be a matter of “you get what you’ve paid for,” but I’m actually still searching.  It really builds a strong case for creating your own potting mixes).

I tracked down a video that gives you an idea of how artillery fungus grows and disperses, and the mess it can make:

I’m so glad that artillery fungus hasn’t been an issue (so far) in my garden!  I hope you haven’t been pestered by it- but if you have, what did you do to get rid of it?
