When and how do I plant Royal Oakleaf lettuce seeds?
Sow Royal Oakleaf lettuce seeds in early spring as soon as the soil can be worked, and again in late summer for a fall crop. Plant just 1/8 to 1/4 inch deep in cool soil; seeds sprout in 7 to 10 days and prefer temperatures of 60 to 70 F.
How many days until Royal Oakleaf lettuce is ready to harvest?
You can pick baby leaves in about 28 days and full loose heads in roughly 45 to 55 days. Because it is a loose-leaf type, you can start harvesting outer leaves early while the plant keeps producing.
How should I space Royal Oakleaf lettuce plants?
Thin plants to 8 to 10 inches apart for full heads, or grow more densely at 4 to 6 inches for cut-and-come-again baby leaves. Rows spaced 12 to 18 inches apart make harvesting easy.
How do I harvest Royal Oakleaf lettuce for repeated pickings?
Use the cut-and-come-again method: snip the outer, oak-shaped leaves about an inch above the crown and leave the center to regrow. Harvest in the morning for the crispest leaves and the plant will keep producing for weeks.
Can I grow Royal Oakleaf lettuce in containers?
Yes, it grows very well in pots and window boxes at least 6 to 8 inches deep. Keep the mix evenly moist and give it morning sun with some afternoon shade in warm weather to slow bolting.
How many seeds are in the packet and are they heirloom?
Each packet holds about 800 open-pollinated heirloom, non-GMO seeds. That is enough for many successive sowings, and you can save seed from plants you let bolt at the end of the season.
Is this lettuce heat tolerant?
It is more bolt-resistant than many types, but for best flavor in hot climates give it afternoon shade and keep the soil evenly moist.
How long do the seeds last?
Stored cool, dry, and sealed in the original packet, the seeds stay viable for a couple of years or more, with the best germination in the first year or two.
