Frequently Asked Questions

What pest or disease most often affects Lactuca sativa (leaf lettuce), and how can I control it?

Leaf lettuce (Lactuca sativa) commonly suffers from downy mildew and aphid outbreaks, especially in cool, damp weather. Improve airflow and water at soil level, then remove badly affected leaves; if aphids appear, spray the undersides with a strong jet of water and use insecticidal soap only if needed. Keep beds weed-free because weeds host aphids and mildew spores.

How often should I water Lactuca sativa during the main growing phase (around weeks 3–6)?

During the main growth period, keep the root zone evenly moist—typically about 1 inch (2.5 cm) of water per week, split into smaller soakings if it’s hot or windy. Lettuce signals stress quickly: if leaves start to feel dry or get bitter/tight, increase watering frequency while avoiding soggy soil that promotes mildew. Aim for consistently damp soil, not waterlogged ground.

How do I tell when Lactuca sativa is ready to harvest at about 60 days?

Harvest when leaves reach the size you want: for loose-leaf types, you can start picking outer leaves as soon as plants form a usable rosette, usually well before 60 days. For full heads (if you’re growing heading types), wait until the head feels firm when gently squeezed; if it feels loose or starts stretching upward, it’s likely approaching bolting and should be harvested immediately. Morning harvesting gives the crispest leaves.

Coastal Star romaine brings a crisp, ocean-fresh crunch with a sweet, clean finish and a tender bite from leaf to rib. Forming tall, upright heads, it offers a satisfyingly firm texture and deep, glossy green leaves that stay attractive in the garden through the growing season. Ideal for fresh salads and hearty wraps, Coastal Star shines wherever you want romaine’s classic structure and refreshing flavor.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 35°F before moving outdoors. Harden off for 6 days first.

Expert Note

Because 'Coastal Star' tolerates heat better than many romaines, set transplants as soon as nights are reliably above the low 40s to avoid slow growth and oversized heads later.
