With a little bit of frost possible towards the end of the weekend, here are some tips on how to protect your plants. If you want the forecast, click here.
What is Frost?
As the air temperature approaches freezing, the surface temperature of the plants can dip below freezing, causing ice crystals to form. This often occurs on clear and still nights. Temperatures vary between the surface and just a few feet above the ground, which is why there may often be times when the thermometer reads a temperature above freezing but there is frost on the ground.
What is Freeze?
A freeze is caused by advective cooling. This is when a mass of colder air enters the area from another location, such as the Arctic. When this occurs, it usually is the signal to the end of the growing season.
Now that we know the difference between a frost and a freeze, let’s go over some of the preparations you can take to protect your plants.
Bring the Plants Indoors
Any frost-tender plants in containers should be brought indoors before a frost or freeze. Be sure to dig up tender bulbs and store them in cool and dry locations.
By watering plants thoroughly before a frost or freeze, it will prevent desiccation. Also, add insulating water to the soil and plant cells.
When deciding which plants to choose, take a look at the type of climate they can live in. By planting frost-tender plants, this will allow them to be easily moved for storage when frost or a freeze is expected.
