Coverage & Planting Details
| Coverage | This packet sows up to 23 feet of trellised cucumbers. |
|---|---|
| Row Spacing | 36" |
| Seed Depth | ½" |
| Seed Spacing | A group of 2 seeds every 12" |
| Thinning | When 3 leaves, thin to 1 plant every 12" |
| Germination | 5–10 days |
| Start Indoors | 2 to 4 weeks before your average last frost date. Cucumbers are sensitive to root disturbance; sow in biodegradable pots. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is at least 60°F, ideally 70°–90°F. |
| Growing & Harvesting | Pick, and pick some more! Overly mature cucumbers on the vine will slow production of new cucumbers. Cut the stem rather than pulling at the fruit, as stems are fragile. To increase the quality and storage time, once picked, immediately immerse in cold water to disperse "field heat". |

- rozann C.Verified BuyerRated 2 out of 5 stars7/10/26not impressed with these seedss
I have been gardening for a long time, (40 yrs) and have bought seeds of all varieties shapes and sizes, and different brands from expensive to cheap. The seeds that I have planted from Botanical have been just so so. Pole beans have gone crazy good, swiss chard, radish, peas hit or miss. same with numerous flower seeds. The cucumbers after planting 3 times, I have finally given up. I checked the soil and saw that some had finally sprouted, but never did get through the soil. I won't be buying as many varieties from you in the future. Gardening is getting challenging for us with the extremes in weather so I am not totally blaming the company. I have always had high regards for Botanical so am not going to give totally up. Thanks for asking.

- RachelVerified ReviewerRated 5 out of 5 stars6/8/26Will grow despite many odds
I'd written this seedling off as my free range chickens had moved the seed to a spot immediately beside the indeterminate tomatoes. Well, this plant has happily decided to climb the tomatoes and their Florida weave. Even producing fruit! Don't skip this variety. It is resilient.

What an amazing survival story for your Spacemaster 80 Cucumber! We love that even after your free-range chickens relocated it, this resilient little plant decided to make the best of its new home by climbing those tomato plants. The fact that it's thriving AND producing fruit in such an unexpected spot just shows how tough and adaptable this variety really is! Your chickens might have accidentally discovered the perfect companion planting setup. Thanks for sharing your incredible Spacemaster cucumber resilience story with us! Keep on growing 🌻️

This cucumber had a very decent germinate rate. I started some inside and some on heat a mat. Both worked well, but I think they germinated a little faster being sowed outside in my Greenstalk, using seed houses. They're all outside now and growing without issue. Hopefully, our FL humidity won't take them out before I get a harvest. Overall, very pleased.

We love hearing about your great germination success with our Spacemaster 80 Cucumber Seeds! It's awesome that both your indoor and heat mat methods worked well, and how cool that the ones in your Greenstalk with seed houses germinated even faster. Your FL humidity concerns are totally understandable, but it sounds like you've got everything set up perfectly for a fantastic cucumber harvest! Thanks for sharing your detailed growing experience with us! Keep on growing 🌻️
- Marilyn P.Verified BuyerRated 2 out of 5 stars4/15/26Easy to germinate. Very prone to rot
Rotted early even with soilless media. Zero “keepers out of first sowing.
Which best describes you as a gardener? IntermediateBIBotanical Interests4/19/26Hey Marilyn,
We're so sorry to hear about the rot issues you experienced with your Spacemaster 80 Cucumber Seeds! That's definitely frustrating, especially when the germination went so well initially. Cucumber seedlings can be tricky with moisture levels - they love humidity for germination but can be sensitive to too much moisture around the stems once they're up. Even with soilless media, sometimes air circulation and watering technique can make all the difference. We really appreciate you sharing your experience as it helps other gardeners know what to watch for. We hope your next sowing gives you much better results! Keep on growing 🌻️
