Here's the video we posted for this challenge:



Cherokee Purple: Indeterminate. 90 days to maturity. thought to have been passed down from Native Americans of the Cherokee tribe. Vigorous vines benefit from strong staking or caging.

San Marzano Tall Vine: Indeterminate. 90 days to maturity. AMAZING for sauce. Grows VERY well here in California.  We made the most delicious sauce last year.  San Marzano is the premier canning tomato with heavy walls, very few seeds and little juice

Mortgage Lifter: Indeterminate. 90 days to maturity.  Kentucky family heirloom grown since the 1930s.  Exceptionally meaty and typically crack-free.

Green Zebra: Indeterminate. 75 to 90 days to maturity. Flesh is bright green and very rich tasting, sweet with a sharp bite to it (just too good to describe!). A favorite tomato of many high class chefs, specialty markets, and home gardeners. Around 3 ounces each and Yield is excellent.


Companion planting is based around the idea that certain plants can benefit others when planted next to, or close to one another. 

Companion planting exists to benefit certain plants by giving them pest control, naturally without the need to use chemicals, and in some cases came mean a higher crop yield

Companion planting for tomatoes includes: Borage, Basil and Marigold (and more).  For a complete list, check out our companion planting guide.

I love give aways, and I love challenges even more lol.
Cant wait for this growing season to start.
I already have Cherokee purple seeds but may have to do an order for the others.
Good luck to all!
Happy growing.


I love Mortgage Lifters and San Marzano, but I never get a very good crop from either of them. I’ve tried Cherokee Purple several times and have never gotten a single tomato from them. Something about the high, dry climate of NW AZ just doesn’t sit well with them.

On the other hand Yellow Pear and other cherry and grape type tomatoes do extremely well. Several hybrids do well here also—but I love growing heirlooms so I can harvest seeds. Rutgers did quite well but my wife didn’t like them as much as the sweeter varieties.

Upshot? I’m still looking for a dependable slicer heirloom tomato. So I’ll keep experimenting while planting cherry and grape types. I’ll be taking you up on your $1.99 deal and will be ordering from you shortly. Beans and tomatoes are probably my favorite crops.

Ray White,

That’s ok. You can still join the challenge if you want. It doesn’t end until September 30th, 2020 which would give you plenty of time to harvest

Mary @ Mary's Heirloom Seeds,

This would be way to early for me to start my seeds. I cannot put them in the ground until May as I live in Illinois zone 5a or b.

Kat keisler,

I pinned this challenge (w/the #hashies). Looking to get some raised beds for this next year, as I’m hoping that will make gardening easier on my back and legs.

LuAnn Braley,
