Sowing: Sow indoors if possible and transplant. Outdoors, sow the seeds in spring after the last frost of the season. Space the plants at least a foot a part, in full sun or partial shaded areas. Germination takes about 2 to 3 weeks. Press into soil, but don’t cover the Lamb’s Ear seeds. Prefers light to germinate.
Transplanting:First, “harden off” your plant for up to 14 days before transplanting. Prep the bed, by turning the soil under 8 inches. Dig a whole big enough for the entire root structure. Loosen the dirt around the root structure, and place the plant in the whole covering the roots. Water thoroughly. Holes should be at least 12 inches apart.
Soil Preference: A rich fertile loam, well-drained and warm. Prefers a light acidic soil.
Other Tips: Try all of the methods to check for ripeness. Give the thick rind a thump. A dull sound usually means it’s ready. Check the bottom. If it is a cream color rather than white, it may be ready. Scratch the rind. If it comes off fairly easily, that may also be a sign of ripeness.
