Can anyone tell me what I’ve done to my poor tomato plants?

[Guest]

Building the greenhouse was the easy part because I have no idea what I’m doing with the plants inside. I’m completely new to gardening and I’m at a complete loss.

Can anyone tell me what I’ve done to my poor tomato plants?

I water from the bottom and trays.

Sunburn. They're pretty tough, they'll recover if you get them some shade..

Well done for starting gardening, and you have a wonderful setup. Keep going!

Greenhouse Megastore has pretty good deals on bulk rolls, and a wide selection of colors and levels of protection. I ordered some recently, but there’s at least a 3 week lead time.

I always watch a ton of different YouTube video whenever I try a new plant so helpful! Just type in how to grow greenhouse tomatoes or starting tomatoes from seed - you will find days and days worth of info!

As others have said, too much bright sun too quickly. They should recover. Next year, make sure you harden them off, meaning gradually introduce them to full sun.

When planting tomato seedlings in the garden, I tend to trim the seedling ‘branches’ about 4” from (top stem). Plan to leave a few little leafs above soil. (This seems a little odd, but the tomato plant will develop roots from spots where the branches were trimmed.) I add a little calcium to the hole and some diluted plant fertilizer, then place the trimmed plant into the pre-dug hole, that is @ 10” deep.

Fill this hole with with soil. There will be only a few little leaves above soil, but you will notice the plant will thrive, with regular watering. Try to water the plant carefully and keep the ‘leaves dry’. As it grows it will need a support…Tomatoes thrive in a sunny location.

Get one of those cheap digital thermometer off Amazon for $8.

There is a hands on learned skill with greenhouses. You need to keep doors open on all days that the outside temp is 60+.

You need a fan for airflow, and in another few weeks (or now depending on your location) shade cloths (40 -50% is what I use) your seedlings look like they either got to cold or to hot ....or possibly both.
