Growing Notes:

  • Harvesting: It can be tricky to know exactly when a watermelon is ripe and ready to pick. First, know the number of "days to harvest" and begin checking fruits as the harvest date draws closer. Signs to look for are: (1) the bottom of the melon (where it lies on the soil) turns from light green to a yellowish color; (2) the surface color of the fruit turns dull; (3) the skin becomes resistant to penetration by the thumbnail and is rough to the touch; and (4) light green, curly tendril on the stem near the point of attachment of the melon is brown and dry. All of these indicators may not necessarily occur at the same time.
  • Attributes: Large, elongated melons with sweet, juicy red flesh weigh up to 35 lbs. each.



"Walked around for two hours. So many options for trees and shrubs, annuals, vegetable plants, house plants. Also great cards and gifts."

"I love this place. Their customer service is absolutely outstanding. The staff has a great amount of knowledge. Anytime I have an issue with a plant, I pluck a leaf off of it put it in a ziplock bag, and then take it in. The staff easily assesses what the issues are and educates me on how to tackle the issue."

"I stopped by Bath Garden Center and Nursery today and was unexpectedly surprised. This family-owned garden center is fantastic. The variety of outdoor and indoor plants is shocking. They also sell pots for every taste. I got two indoor plants and went to the cashier. Lauren was excellent at taking me to an available cashier and ringing me up. She kindly offered to put my chosen plants into the new pots I bought. I wish this family had more stores across Colorado."
