Martha Washington is generally regarded as a hardy plant, so this plant will survive close to or on freezing temperatures. They will grow up to 9 ¾ inches tall and spread about 1 ½ feet. They prefer full sun. Harvest is usually mid spring. Do not harvest the first year after planting — wait until the second year. Keep clear of weeds and do not disturb roots. May be “hilled up” with compost or mulch in spring to blanch the spears. Most common pest is the asparagus beetle, which may be discouraged if tomatoes are planted nearby.
