Dig in lots of compost or rotted manure and add half to 1 cup of complete organic fertilizer per plant. On the coast, with protective mulch, these plants may overwinter. In late October cut back to 15cm (6") tall, and mulch well with straw, soil, leaves, or burlap, to keep the roots from freezing. Uncover in April.||It takes some work and a lot of patience to grow artichokes from seed, but it's worth the effort. Commercial culture is limited to warm areas hardiness zone 7 and above. Artichokes require good soil, regular watering and feeding, plus frost protection in winter. Before frost, cut back to 15cm (6") tall and mulch with soil, straw or leaves to keep the root from freezing. Uncover in April. Offshoots of these plants should be set out in the spring, so that the older plants can be replaced after a few years.
Start indoors in late January to early February under bright lights.
Sow 2 seeds per pot, 5mm (¼") deep. Keep moist in a warm place until seeds germinate in 10 to 21 days. Transplant seedlings into the garden 2 weeks after the last average frost date for your area. Artichokes need a cool period (250 hours) below 10°C (50°F) to induce flowering, but will not survive hard frost. Space plants 1m (3') apart. Seeds can also be germinated between damp sheets of paper towel.
In optimum conditions at least 70% of seeds will germinate. Usual seed life: 1 year.
|Green Globe artichokes grow on such attractive plants that they are often found in the flower garden. A little patience is needed but the wait is worthwhile. A rich and deeply dug soil is required for the plants to produce their best heads. Starting in March or April, sow seed outdoors 1.5cm (0.5") deep in a seedbed and transplant to the permanent position when seedlings are large enough to handle. Water well. Allow 2-3ft between plants as they will eventually reach a height of 5ft. Young plants produce their best heads in the second year of cropping and become more prolific each year. To cook, rinse thoroughly under a tap and remove the pointed tips. Boil in salty water for 20-40 minutes until tender. Drain upside down and serve hot with melted butter or Hollandaise sauce.|
