Vines rebound rapidly from transplanting, bulking up quickly to set clusters of massive, flattened pink-red slicers weighing 14-25 oz (400-700 g). Growers highlight its exceptional plant vigor, heavy production even in short-season regions, and classic sweet, juicy beefsteak eating quality. Full summary ↓
Growers’ Notes and Photos (USDA Zone 4 Experience)
Seeds came from Angelina.
Catalog notes:
Mind-blowing yields of huge, juicy, and delicious fruit! Indeterminate, mid-season, tall grower, strong disease resistance. One of the highest yielders around!
Total stunner! Put it in the ground as a tiny start, no more than 8 inches (20 cm) tall. It took hold immediately, bulked up, took off with crazy vigor, and cranked out a serious haul of these hefty, flattened whoppers! And delicious to boot!
Full Summary: Plant Vigor, Yield, and Fruit Quality
- 🌿 Growth Habit: Indeterminate, robust vine with exceptional vegetative push. Establishes its root system quickly after transplanting, transitioning rapidly from an undersized start into a stout, heavy canopy capable of supporting large fruit trusses.
- 📈 Productivity: Renowned as one of the heaviest croppers in the beefsteak class. Sets multiple flattened, lightly ribbed whoppers without dropping blossoms in midsummer.
- 👅 Flavor & Texture: Slices reveal dense, meaty locules filled with rich juice. Delivers an old-fashioned sweet and rich heirloom flavor.
- 🌎 Who Reviewed It: Tested in USDA Zone 4 (Vladimir Region), proving that even stunted or small transplants can catch up and deliver heavy yields in a short growing window.

👨🌾 Editor’s Note: Rebound Vigor on Heirloom Beefsteaks
Yulya’s note about transplanting an 8-inch (20 cm) start highlights a valuable agronomic trait: Megamutt displays exceptional compensatory root vigor. Many large-fruited beefsteaks suffer prolonged transplant shock if set out too young or root-bound, but vigorous workhorse lines like Megamutt push heavy lateral roots early, quickly making up lost ground compared to more finicky varieties.
