That headline is almost certainly meant to spark curiosity. Simply burying unpopped popcorn kernels around a blackberry bush is not a proven gardening technique that produces dramatic results.
Here’s what can actually happen:
- The kernels may decompose over time, adding a very small amount of organic matter to the soil.
- Some kernels may sprout if they’re viable and untreated, growing into corn plants—not benefiting the blackberry directly.
- Wildlife may dig them up. Birds, squirrels, mice, or other animals often eat buried kernels.
- There is no evidence that popcorn kernels act as a fertilizer or significantly improve blackberry growth.
If you want to help a blackberry bush thrive, methods with good evidence include:
- Adding compost or well-rotted manure around the base.
- Applying mulch to conserve moisture and suppress weeds.
- Watering consistently during dry periods.
- Fertilizing according to the plant’s needs, especially in early spring.
- Pruning out old canes after they’ve fruited.
So if you see a post claiming that burying popcorn kernels led to an amazing transformation in just three weeks, it’s likely leaving out other factors or exaggerating the results. A healthy blackberry bush responds much more to proper soil, water, sunlight, and care than to buried popcorn.
