heat tolerant lettuce...

bunkie · July 30th, 2010, 12:22 PM

90 degree lettuce!i started this lettuce week before last for the first time...they're 2 heat tolerant varieties...'Summercrisp' and 'Heatwave'. it's been 85F to 90plus every single day since i planted them! so far so good! they get morning sun and then shade on our porch.

Where did you get those seeds? I'll have to try some for next season. I had some red oakleaf last year, which was very heat resistant, as it lived into July, and didn't even bolt, though it basically stopped growing. However, this season it gave in, and bolted, with that record hot June we had. I had to pull all of my normally later greens - the hot lettuces, Swiss chard, and some of the Asian greens - as it was just way too hot, with no rain on top of it.

My buttercrunch and red sails have been doing fine in upper 90 deg temps. I grow them in a 60%shade cloth tunnel and water often.

hey pepper, i got the 'Heatwave Blend' a few years ago at Cook's Garden...

http://www.cooksgarden.com/index.cfm...-d8bada78dc7b/

and 'Summercrisp Blend' this year at Bountiful Gardens...

http://www.bountifulgardens.org/searchprods.asp

i wanted to add that there seems to be two different descriptions of this last lettuce...one rare red butterhead, and the other a slow bolting green. i just wrote the company to find out which it is...will follow up here...

hey cape, this is the first time i grew lettuce this time of year, and i'm very pleased so far...

I do pretty well with Amish Red Deer Tongue Leaf year 'round.

Did you germinate them in the heat??? I've got some outside and some in an air conditioned room...none so far have germinated. I'm not sure why.

Here is a list that I started years ago. They are all supposed to be heat tolerant.

Tropicana
Avenue
Jericho
New Red Fire
Bronze Arrow
Green Towers
Nevado
Seirra
Rouge de Grenoblouse
Tahoe
Winter Density
New Red Fire

Red Sails and Butter Crunch have always been a good lettuce for me. I gave up on the Iceberg types years ago because every place I have lived they would go to seed way to soon.Besides you get more nutrition out of good leaf lettuce then you will the Iceberg types.

i have Jericho seeds i haven't planted yet.

these seeds i just put in a flat of potting soil and covered with black plastic and put in a cool place in our cabin. personally, i've found that cool and dark help lettuce to germinate, no matter what variety.

Thanks Bunkie! I couldn't find the summercrisp blend (just two individual summercrisps, with identical descriptions!) on the Bountiful site...is it out of stock, thus not listed? It didn't look like it is the slow-bolt mix they have, as that has a totally different description.

Now I have to find a fall/winter mix! Cook's Garden has one of those. I said no more ordering, buuuuut....

Some things never change.
