I hate to use this "F" word in May, but it's happened before and may happen again Friday morning and Saturday morning....FROST! They are calling for lows in the upper 30s. With low winds and a specific humidity level we could get frost. Freezing temperatures aren't required; lows around 37 to 42 degrees can produce patchy frost. The prediction is for 39 degrees Friday morning and 38 degrees Saturday morning—definitely in the frost danger zone!
Fortunately your spring gardens are very well along and frost will only majorly damage lettuces and arugula. Frost may affect the tips of the leaves of other plants, but they should not be adversely affected at this stage in their growth.
To protect your lettuces and arugula, lay an old bed sheet or other light cloth over these crops. Do not use plastic though as frost can actually burn plants that touch the fabric. Cardboard is another option; if you have some extra boxes lying around, you could place them over these crops as well.
Maybe your best option is to harvest a good majority of the lettuce and arugula, wash it and dry it very well. Then store it in the crisper drawer of your refrigerator, covered with a damp paper towel. Leafy greens stored this way will last a week or more easily.
Fingers crossed this is the last frost of the season! Our average last frost date here in KC is April 10th, but we've had patchy frosts as late as Memorial Day weekend! We've also had snow on Mother's Day. Just part of the tribulations of growing veggies!
