2023 Garden Challenges February Update Posted on 1 Feb 14:44 , 5 comments

February 1, 2023

If you are just learning about our 2 garden challenges for 2023, I highly recommend going back and reading the intros and watching the video.

You'll find them here:





So you've purchased you seeds from Mary's Heirloom Seeds. Now what?

Get Growing! Ok, so maybe not yet if it's still frosty outside. Right now, it is 30 degrees in Ben Wheeler, TX so I'll be planting my seeds a little later. Our last frost date is Mid March so I still have time to plan.

I did test the germination on my seeds to give you feedback for our February update. I soaked 10 seeds of each types of watermelon seeds mention in the challenge. Florida Giant and Carolina Cross. 9 out of 10 seeds germinated from each pack but the Carolina cross took 5+ days more to germinate than the Florida Giant. Interesting. This should be fun!


If you have not already sent me an email letting me know that you'll be joining us, please do so as soon as possible. Please email: MARY@MARYSHEIRLOOMSEEDS.COM


Are you ready for the prizes?

The first prize for the largest Pumpkin and the largest Watermelon is a $50 Gift Card to Mary's Heirloom Seeds

The second prize for the second largest Pumpkin and Watermelon is a $25 Git Card to Mary's Heirloom Seeds.

And there's more...

The Funkiest shaped Pumpkin and the Funkiest shaped Watermelon winners will each receive a $15 gift card to Mary's Heirloom Seeds

Just for participating, I will pull 4 random winners from a bowl and each of the winners will receive a $15 gift card to Mary's Heirloom Seeds

I might add a few more prizes as we go a long just to add to the fun. Stay tuned!

If you are joining our challenges and you would like to let everyone know, please comment below. And please consider sharing this info on your social media accounts using #marysheirloomseeds #growagiantwatermelon #growagiantpumpkin

I will post monthly updates and videos on the first of each month.
Thank you and happy planting!

Grow a Giant Pumpkin Challenge Posted on 11 Jan 15:16 , 1 comment

January 2023

Happy New Year!

Are you ready for another 2023 garden challenge? The First challenge was announced a few days ago.


There has been a "growing" interest in new garden challenges at Mary's Heirloom Seeds. Growing watermelons in the garden is fun and easy.

But what about Pumpkins? We LOVE Pumpkins!



Did you know that the world record for the largest pumpkin in the US is 2,560 pounds? "Travis Gienger, of Anoka, Minnesota, set the record while winning the 49th World Championship Pumpkin Weigh-Off in Half Moon Bay, south of San Fransisco."

We offer 2 varieties of Pumpkin seeds at Mary's Heirloom Seeds that can grow pretty large. Big Max Pumpkin weighs up to 100 lbs. or more when well grown. Bright orange fruits with orange flesh good for pies. Dill's Atlantic Giant Pumpkin is a massive variety that produce 400 to 500 pound pumpkins consistently but the record for this variety is 2009 pounds!


Would you like to join us?

Here's how it works. This is going to be a fun contest with prizes at the end of the season.
