Which Plastics Are Safe For Gardening?

One of the more common questions I'm asked on the blog is about plastic use, specifically, "What plastics are safe for use in the garden?"  Since

When it comes to plastics, the saying goes: 4, 5, 1, 2, all the rest are bad for you.

However, #1 (PET) is not ideal since it’s often thin and intended for single use (think plastic water bottles) . Hence, it breaks down quicker and may pose a risk of leaching.

Consider re-using these for your gardens.
#4 - LDPE
#5 - PP
#2 - HDPE

    Honestly, you shouldn’t probably just use hdpe and pp if you’re concerned about ea leaching.

    And if there is exposure to UV radiation (sunlight), then hdpe is the better option. However one can either use UV protected pp, paint or cover the pp to mitigate the UV effects.

    There is more to be said about micro plastics however and a lot is still unknown.
