Sink your spoon into Park’s Whopper and you’ll meet a lush, garden-ripe sweetness wrapped in a classic slicing tomato tang.

Grow this 85-day favorite for bold, vibrant summer salads and rich, spoonable sauces that celebrate its full-bodied flavor at peak ripeness.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 60°F for reliable germination and early growth.

Expert Note

Start indoors early for Park’s Whopper, then transplant only once soil is at least 60°F and nights are consistently above 50°F to keep the plants from stalling.

Frequently Asked Questions

What pest or disease is most likely on Solanum lycopersicum (tomato), and how do I stop it?
Early blight (Alternaria) is common on tomatoes in home gardens, showing up as dark, concentric “target” spots on older leaves and can progress upward. Remove and discard affected leaves early, keep foliage dry by watering at the soil line, and apply a labeled fungicide that targets early blight if spots keep spreading. If you can, start with resistant varieties and avoid working in the plants when leaves are wet to reduce spore spread.
How often should I water Solanum lycopersicum during the main growing phase?
During active flowering and fruit set, keep soil consistently moist but not waterlogged—aim for about 1–2 inches of water per week depending on heat and rainfall. Water deeply 1–2 times weekly so moisture reaches the root zone, then let the top few centimeters of soil dry slightly before watering again. Mulch helps prevent swings that cause blossom-end rot and cracking.
How can I tell when Park’s Whopper (Solanum lycopersicum) is ready to harvest?
Harvest when fruits are fully colored for the variety and have a slight give when gently squeezed (not hard like a green tomato). The fruit should detach from the vine with a light twist; if it resists, give it a few more days. For best flavor, pick at peak color even if you see slight softness at the stem end.
