please Water Your Landscapes, to prevent drought and help wildlife

Ive been trying to educate people on the water, drought issue and just found this wonderful post written by Wynn, a gardener and landscaper from Bowen Island. It is written so much better than I could say, so here it is:

I’ve been asked a few times now if I would post this to the forum as well. If you’ve already seen it in The Office bulletin, my apologies. 🙂

This is an article that was kindly published by The Office bulletin in Artisan Square recently. Water is such a central issue to gardeners everywhere, not to mention our broader environment and the stuff of life itself!

My view is that we are experiencing not just a dry period between more normal weather cycles but a persistent, likely permanent, drying trend due to climate change. If that is so, then past practices that were adequate to get us and our plants through a temporary dry period are no longer adequate or even the right remedies to deal with what appears to be is a global drying trend.

However, the solution is not to let our landscapes die! Plants, trees, shrubs and ground covers act as our highly efficient air conditioners. Replacing them with barren ground, rock mulch, artificial turf or green painted surfaces is not only futile, it makes the problem worse. How is replacing living green surfaces that holds and filters clean water back into our aquifers, with heat absorbing rock mulch or plastic artificial turf supposed to cool the surrounding air?

Strategies such as imposing 4th level water restrictions disallowing any outdoor watering of plants, topping up of natural wildlife-friendly ponds (not swimming pools or hot tubs) or giving birds and other creatures a source of water where needed, is not “wasting water”. This is not a strategy. It is not a solution. It is an act of panic and desperation. As we lose the green, our world turns brown, not just our lawns. It needs a proactive not reactive response by municipalities and individuals working together. Rant over now, thank you.

Have been meaning to write about this for some time now. As a gardener, I am reminded every day.

We all are experiencing, first hand, the effects of warming and associated drought along with the rest of world, however unlike many others we still have drinking water, water to wash ourselves and to grow food. We are just beginning to be alarmed at the longer term consequences of a drying world.

Yes, we waste a lot of drinkable water, no question. Our water consumption, even when restricted for a few months in the summer, is generous compared to many other regions of the world. But I think we are mistaken, in some respects, in our understanding and definition of “wasted water”.

When is water wasted? We can argue that it is wasted in large and small ways but is it wasted when it’s plentiful or only in the dry summer months when less plentiful and expensive? Is it wasted by our building regulation and infrastructure practices that allows rainfall to roar off roofs and through drains and culverts into the sea rather than permeating the ground to nourish plants and replenish aquifers? I think so. California certainly knows the effect of ever diminishing aquifers and reserves. We absolutely need better building and landscaping practices in a drying world. I would also argue that using clean, especially treated water, for power washing buildings or cleaning cars and decks is a use that should probably be reexamined in today’s world.

And then, the main purpose of this letter, is it being wasteful to share water with our living landscapes and creatures. I would argue that it is not. Keeping our tended and wild landscapes alive and healthy is of the utmost importance – as it creates and maintains a livable world for us all.

What is the antidote for dry and hot; it is moist and cool. You know that feeling you get when you leave the heat of the asphalt road or cement parking lot and plunge into the adjacent forest? The ambient temperature immediately drops what feels like several degrees, you can suddenly breath easily as moist air fills your lungs, it smells earthy and cool. Ahhh, relief. That’s what our personal gardens, community parks, ponds, lakes and natural areas bring to us. Rescue and respite from our hot urban deserts. Yes plants consume water. They also transpire continuously, releasing that water into the air as moisture that, in turn, cools and dampens the air around us. They are our air conditioning.

When I hear people discussing whether to bother planting a garden, to water that thirsty tree or, worse, to pull up existing landscaping in response to drought and water restrictions, I almost despair. The solution is not to let landscapes die. The solution is to plant more tree canopy and shrub layers for permanent ground protecting shade and to plant barren eroding ground with a living surface that holds and filters clean water back into aquifers. The solution is to protect and increase our native forests, wetlands and lakes as a counter balance to a drying climate and urbanization; to mitigate, not reduce and diminish it. The solution is to “green” our buildings, streets and urban spaces, create significant public parks, collect rain water and use ground permeable landscaping and green roofs for cooler cities. As we lose the green, our world turns brown and dry, not just our lawns.

Garden trees and shrubs suffering repeated near-death experiences every summer with no or shallow watering are never going to develop deep, drought resistant roots. They need deep watering, less often. A timed trickling hose or focused “spot” sprinkler does a good job, also tree “water bags”. After a few years of sufficient watering there may not be a need to water these hard stemmed plants at all. Hand spraying, unless done properly, is often less effective than a tree waterbag, a focused spot sprinkler (NOT the wide/high spraying ones) and mulching. And may not use less water in the end. Ask, research, educate yourself and talk to neighbours about the best practices. Your garden will reward you.

We need to be pre-emptive, innovative and smart about water, not reactive and panicked. And that goes for municipalities and Boards as well. Get on with changing the big stuff, e.g., obsolete building practices, allowing grey water systems, mandatory cisterns, collection reservoirs, permeable landscaping, greening urban spaces, metering, public education, creating parks, protecting our green “air conditioning”. We citizens will take care of the small, but vital stuff.

And, lastly but so importantly, flora and fauna need and are entitled to have water to live, too. We need to share — it’s not just about us.
