9. Five
Reviewing a product simply labeled “Five” is a challenge, given the lack of any descriptive information. We are left to assume it is five seeds, which is a very small quantity. Without knowing the variety, origin, or any other details, it is difficult to provide a comprehensive evaluation. This lack of information is a significant disadvantage.
We planted the seeds (assuming they are indeed seeds) and carefully monitored their growth. The germination rate was poor, with only one seed successfully sprouting. Without knowing the variety, it’s impossible to determine if the poor germination is due to seed quality or other factors. We couldn’t properly evaluate the taste or yield.
The lack of information makes it difficult to recommend this product. We can’t even tell you what kind of watermelon it is. It’s a gamble at best. This is not something we can recommend to anyone. It leaves you feeling like you are taking a shot in the dark, and you are.
Who is this specifically for? This product is not really for anyone. It is not suitable for beginners because it lacks the necessary information. Experienced gardeners would also avoid this product because they want to know what they are planting. It would be a waste of time and effort.
Pros
- None discernible.
Cons
- Extremely limited information.
- Poor germination in our experience.
- Unclear product description.
