Indigo Apple Tomato Seeds (Organic)

Indigo Apple is an indeterminate tomato that produces medium-sized fruit with dark purple-black shoulders over red skin. The firm, juicy tomatoes have a balanced sweet-tart flavor suited to slicing, salads, and fresh salsas. Start seed indoors 6–8 weeks before the last expected frost. Transplant after frost danger has passed, once seedlings are hardened off and the soil has warmed. Grow in full sun in fertile, well-drained soil, and provide a cage or trellis for the vigorous vines. Water deeply and consistently at soil level.

Plan Indigo Apple Tomato as a warm-season crop. Start seed in a protected setting when local timing allows seedlings to reach transplant size after frost danger has passed. Provide strong light and avoid keeping the root zone continuously saturated. Use the recorded spacing and add support if the growth habit requires it. Check fruit as it changes color and firmness, then harvest at the stage suited to its intended kitchen use. Seasonal conditions can shift actual maturity.

Harvest when the lower portion of the fruit is fully red and the fruit gives slightly under gentle pressure; the dark shoulder color develops with sun exposure.

Before sowing Indigo Apple Tomato, review the packet alongside the current product details and note any range in temperature, germination, or maturity. Ranges reflect biological and seasonal variation rather than a fixed promise. Label each planting with its date and location, then compare emergence, growth, and harvest with local weather. This record is useful for succession plantings and for deciding whether the crop fits better into an earlier or later seasonal window.
