A very strong growing and productive variety. Asparagus 'Mary Washington' produces long, thick spears in May and early June that are delicious eaten fresh from the garden and are also suitable for freezing. Although asparagus beds take several years to establish, each asparagus crown can produce up to 25 spears per year and will continue cropping for 25 years. Height: 150cm (59"). Spread: 45cm (18").
Sowing
Direct sow asparagus seed outdoors in mid spring in a well prepared seed bed. Choose a sheltered position in full sun. Asparagus beds should be richly fertile and well drained. Remove all weeds, and incorporate plenty of well rotted manure or garden compost into the soil to improve soil structure and fertility. On cold, wet soils the addition of sharp sand or grit will help to improve drainage. Soak the seeds for 48 hours in warm water before sowing 5cm (2") deep, 8cm (3") apart in drills 30cm (12") apart. Asparagus seed germination is slow taking 21 - 30 days.
Alternatively asparagus seeds can be started off under glass. When large enough to handle, thin out asparagus seedlings to 30cm (12") apart, and grow on for a season. The following spring (late March/April) transplant young asparagus plants into a well prepared bed. Plant asparagus crowns 45cm (18") apart in rows 1.2m (4ft) apart taking care to ensure that the roots are not cramped.
