Tires for gardening
To the Editor:
I read in the article, Garden Spaces For Small Places, By Dorothy Ainsworth, about making used tires into small beds for vegetables or flowers.

The only problem is that mulch made from shredded tires leaches chemicals into the soil. A study in an organic gardening magazine mentioned zinc in particular, and suggested that other heavy metals might also be found in quantity.

It would seem to me, that the only difference between tires, and mulch from tires, is the increase in surface area. Shredded tires would leach faster than whole ones. Still, how much faster? Better safe than sorry.

Thank you for your time,

Ben Homer

I googled: "Are tires safe for gardening?" and found mostly positive answers and why.

Shredded tires for mulch do tremendously more surface area for leaching, so I would not recommend that, but whole tires are chemically stable. They have been run at high speeds and the inner surface has oxidized so the surface molecules have formed a seal. If worried, a person can always line the tire with gardening plastic.

I personally am not worried at all, especially for short term use, but to assuage any trepidation, simply google the same question I googled and read the answers. Many of the answers are from scientists and they aren't worried either about the use of whole tires.

The main culprit
would be zinc but in whole tires it doesn't leach out fast enough to do any harm according to most of the reports I read. One report said the plant will only take up what zinc it needs and that's it. Our bodies use zinc, so it's not like a toxic poison, unless we overdose, but that goes for any vitamin or mineral.

True, it IS better to be safe than sorry, and Ben Homer's question was a good one, but by doing some extra research I still feel secure in using tires for gardening. But after reading all the reports yourself, you are free to draw your own conclusions and make your own informed decision "to use or not to use" tires.

Using Tires as Raised Garden Beds?
by Margaret
(Ireland)

Can old rubber tires be used as raised beds for vegetable gardening? If so what sort of preparation would they need...cleaning, or lining? I like to recycle where possible and I have access to quite a lot of tires.
P.S. These beds would be used for vegetables and fruit...thanks.


ANSWER:

Yes, many a gardener has successfully used old tires for vegetable gardening.

If the tires are dirty, you can clean them with soap and water. You do not need to line them.


Tires filled with straw are an especially great way to grow potatoes! You put a thin layer of straw on the ground, then lay the seed potatoes on the straw. Cover them with a layer of straw. As the plants begin to grow, add layers of straw half-way up the foliage until you reach the top of the tire with the straw.

How safe is it to use old tires as a raised garden? I know I can do flowers but just wondered about a small garden. Thanks for your help.

I have a few tires set up as retaining wall, and want to plant in them. Could I line them with black plastic (can't find the # for it ) or how about old pool liner?
