Leaf lettuce 'Red oak'

Grows best in full sun and in cooler weather, but will tolerate some heat. Mulch to control weeds and keep soil moisture consistent.¹

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Red oak is thought of as hardy, so Red oak will tend to go dormant or grow slowly over the winter months. Ensure your soil has a ph of between 6.2 and 6.8 as Red oak is a weakly acidic soil loving plant.

Sow outdoors as soon as soil can be worked or start indoors 4-6 weeks before transplanting.

Look to ensure a distance 0.12 inches (0.3 cm) between seeds when sowing - bury at a depth of at least 0.49 inches (1.25 cm) deep. Soil temperature should be kept higher than 7°C / 45°F to ensure good germination.

By our calculations, you should look at sowing Red oak about 28 days before your last frost date.

Thin to 8-12" apart

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Red oak is a hardy plant.

This variety tends to be ready for harvesting by late spring.
