Hardening Off Tomatoes 2022

1 Comment

This week’s weather in my part of Connecticut is fantastic. My tomato babies will love the heat in the greenhouse from the sun and the breezes flowing thru the doors and vents. I am not, however, putting my tomato plants outdoors yet too much because it has been very breezy and windy. I use caution because I don’t want to dry out the delicate tomato start leaves.

This time of year is very busy for plant business people so I don’t really even have that much time to write this am, but as I sip my coffee no. 2, I wanted to post a quick hello and a pic or two. When the breezes subside, I will be rotating out my tomato starts in groupings this week to harden them off (acclimate). I try to avoid full sun and place them on trays where there is some shade from a nearby dawn redwood tree (a tree very useful because it looses its needles in the winter (thus, no shade is cast during winter on my greenhouse) but gets the needles growing now so it provides the shade I enjoy for my hardening off of the tomato plants.

If you put your tomato plants out in full sun immediately from your indoor growing environment, it will burn the leaves and white patches will appear on the leaves afterwards (usually you will see it the next day on the leaves). So I always do shade, part shade, part sun and luckily I have that available. I also use tables, shelves, and it becomes a little crowded, but in addition to focusing on hardening off the plants in non-full sun locations at first, I make sure things are spaced inside and out to allow air circulation around the plants. This helps prevent diseases on the leaves or other issues.

Some of my tomato starts are ready to be potted up and I usually do some to one gallon pots as needed. Others are still okay in their smaller pots, but if they start to lean, I know it is time to twine them to a small wooden stake.

Most of my plants are spoken for now, but I believe I still have some of the wonderful heirloom Cherokee Purples available. And Ground Cherries, those are still small and I’m not sure why, but I have faith they will perform when the time is right. This is the first year I am growing the Ground Cherries from seed. They are like hot pepper plants apparently, they really need heat to grow well from seed. I discovered the ground cherries last year, they taste like pineapple!

Ground Cherries from a site I visited last year in New Hampshire – inspired me to try them this year!

Well, this is all I can write for today, I have to get out there, get plants watered, out and then off to a site to prep for planting later this month. BTW, I wait to put my tropical plants and tomatoes/warm season vegetables in their permanent outdoor pots and or grow bags till Memorial Day. Hardening off is taking place now on good days with sun and not too windy or cool conditions. And I will rotate them out in groupings. Plus they still need to grow some. So happy about the great weather to do all!

Have a great day and week! Enjoy this weather!!
