Frequently Asked Questions

Why are my Black Krim tomato leaves turning yellow with dark spots, and what should I do?

Yellowing with dark, spreading leaf spots is often early blight or Septoria, which flares in warm, humid weather. Remove and discard the affected lower leaves, improve airflow by spacing plants, and water at the soil line (not on foliage). If it keeps progressing, spray an approved tomato fungicide and repeat according to the label, starting as soon as you see spots (before they reach the canopy).

How often should I water Black Krim tomatoes during the main growing phase (from flowering through fruit set)?

Water deeply about 2–3 times per week during flowering and fruit set, aiming for consistently moist (not soggy) soil. The target is even moisture: let the top 1 inch of soil dry slightly, then water until the root zone is soaked. Irregular watering can trigger cracking and blossom-end rot, so avoid quick, daily splashes and instead use slower, thorough watering.

How can I tell when Black Krim tomatoes are ready to harvest?

Harvest when the fruits are fully colored (deep red to mahogany with a pinkish marbling near the shoulders), and they yield slightly to gentle pressure. For Black Krim, wait until they’re not mostly green—at about 85 days you should see dependable ripening, but pick as soon as they feel ripe because flavor improves as they fully color. Avoid leaving them to over-ripen on the vine during hot, wet spells, which increases cracking and disease risk.

Sink your spoon into the first glossy slice of Black Krim—its smoky, wine-dark flesh carries a rich, sweet-tang balance with a hint of old-world depth. Beefsteak-sized fruits are wonderfully meaty and juicy, with a slightly irregular, heirloom charm and a tender, satin-like texture that shines in the garden. Grow Black Krim for bold, showy summer harvests that beg to be showcased in fresh salads, vibrant sauces, and savory roasting-style preparations.

Sowing Tips

Transplant Conditions

Wait until soil reaches 60°F and nights stay above 50°F before moving outdoors. Harden off for 8 days first.

Expert Note

Start seeds indoors about 7 weeks before your last frost, then transplant only when soil is reliably 60°F+ and nights are staying warm to avoid cold-stunting Black Krim.
