The Story
Plant Bio
Solanum tuberosum, the common potato, is an upright to spreading herbaceous perennial grown globally as an annual root crop. The species produces dense, dark green compound foliage on thick stems, followed by clusters of star-shaped flowers and small, toxic green berries.
'Agria' is a robust German-bred cultivar distinguished by its high-yielding, yellow-fleshed tubers and strong, rapid initial foliage development. In summer, it produces large, numerous white flowers held above the canopy on unpigmented stems.

Planting
How to Grow
- Select a planting site in full sun with loose, deeply dug, acidic soil.
- Cut large seed potatoes into pieces containing at least one eye, allowing the cuts to dry for a day before planting.
- Plant seed pieces ten to fifteen centimeters deep with the eyes facing upward.
- Mound soil or mulch progressively around the emerging stems to protect developing tubers from sunlight.
- Maintain consistent soil moisture throughout the growing season, particularly during flowering and tuber initiation.
Pro Tip
Cut the leafy vines down to ground level two to three weeks before harvesting to toughen the tuber skins, which prevents bruising and extends storage life.

Care Guide
Do
- Use certified disease-free seed potatoes to prevent viral and fungal infections.
- Apply a potassium-rich fertilizer to support healthy tuber development.
- Rotate potato crops annually to a different garden bed to disrupt pest and disease cycles.
Don't
- Do not prune healthy green foliage during the growing season, as this reduces tuber yield.
- Do not allow developing tubers to be exposed to sunlight, which turns them green and toxic.
- Do not over-fertilize with nitrogen, which promotes excessive leaf growth at the expense of tubers.
