Early bird gets the frost! That's what I get for planting flowers in my planters before the May long weekend. Here in the Canadian prairies, there is always a risk of frost during the month of May. I knew better but wanted flowers more.

Caught off guard by the frost warning on the news, Mr. Frugalista and I ran outside in the rain to quickly make frost blankets with clear bags. If you live in a 0-3 plant hardiness zone and get caught off guard too, here's an idea for how to quickly protect flower planters from spring frost in a pinch.

How To Quickly Protect Flower Planters From Spring Frost

We got soaked in just the five minutes it took to cover all our planters. Everything you need to make these flower planter frost blankets you may already have in your shed. But if you don't, you may want to keep the suggested supplies handy so you are prepared for that unexpected frost warning.

Before we get into the nitty-gritty of how to make the easy peasy flower planter covers, almost all of the DIY projects shared here at Interior Frugalista have step-by-step tutorials so why not get your budget DIY on and subscribe. You can also follow us on Pinterest, Facebook, Instagram, and YouTube.

Instead of frost, we woke up to a blanket of snow - in May! The flowers should be insulated enough under the plastic to survive this unexpected surprise.

Here's How We Did It

You can get as fancy or as simple as you like to make these flower planter frost covers.

Simple Flower Planter Frost Blankets

We used leftover PVC pipe from our raised garden covers because we had them on hand. But 1 x 1 lumber, tall wooden plant stakes, or hula hoops crossed in the middle would work. Simply stick the stakes into each corner of the flower pot and then slip a clear plastic yard waste bag over top. That's it!

An alternative is to use old sheets but they get weighed down when wet. It's so much easier simply slipping a clear yard waste bag over the stakes to cover the flowers. Plus you can tie the bags on the bottom so the wind doesn't blow them off. Even better, use drawstring yard waste bags to tie them.

Raised Garden Bed Frost Protection

For your raised garden beds, you can get all fancy and make these mini-greenhouses with hula hoops or flexible PVC pipe.

We plan on storing these designated frost blanket stakes in a bucket labeled frost blanket supplies so next time we get caught off guard, we're prepared. Because there is a likelihood they'll be needed again in late summer in our region.

Once the frost warning has been lifted, here's an idea for keeping those flowers blooming all summer long with this DIY Eco-Friendly Rainwater System. If you want to save your back when planting your annuals, here a simple potting bench idea that you can make in an afternoon.
