Does Rubber Mulch Crack and Freeze in Cold Weather?

As the temperature steadily drops, apprehension about how to keep plants properly insulated rises. Those who invested in rubber mulch for their gardens, landscaping, and other infill needs have been wondering if shredded rubber will crack and freeze in cold weather.

This seasonal concern is perfectly understandable – who wants to welcome spring with soggy roots and wilted leaves?

The thing is, since rubber mulch does not absorb water, these fears are unfounded. Rubber does not freeze in the same manner as other objects – ice crystals won’t form on it. In fact, one of the best wintertime benefits of rubber mulch is that it is slip-proof, making it safe to walk on outdoor pathways covered with them.

Rubber mulch is made of shredded old tires. It’s true that new rubber tires stand up better to cold weather compared to old ones, but as long as no excessive force is used on them, they can still perform satisfactorily. Also, rubber that comes in nuggets already go through an extremely low-temperature treatment when their steel parts are removed. The fact that they come out resilient and sturdy means they’re pretty hardy little things.

And because it doesn’t retain water, you won’t have to worry about fungi, mold, and other harmful things growing on rubber mulch and affecting your plants during cold weather. It also doesn’t decay, so it won’t contribute to the soggy post-winter mess most organic gardeners have to deal with yearly.

As rubber mulch is beneficial in warmer weather, so it is during the cold. Think of it as an all-season mulch that only wants the best for your garden, landscaping, and other outdoor cover needs.
