Today you will start hardening off the broccoli and cabbage you planted on April 3. You will also start hardening off your zucchini (summer squash).
Once you get all that hauled outside somewhere safe, you can go plant the 20 cabbage plants that have been enjoying the sun while you've been laboring out in the garden this last week - the ones you started on April 3. Plant only the healthiest ones; with luck you'll have a few left over. Planting those few extra leaves room for some to not make it.
Once again, just a reminder, don't let your babies stay outside too long the first day, and a little longer each day. You'll be planting them next week.
Enjoy your break. See you next week
