Where to Plant Artichokes
Artichokes are easily adaptable plants, you can either grow them in containers or raised soil beds in your garden. The reason artichoke plants die even before developing buds is because of insufficient watering in the summer and waterlogged soil in the winter. Plant them in areas that receive full sun to partial shade with easy access to water and drainage.
When to Plant Artichokes
Artichokes grow best in medium summers and mild winters. For growing artichokes as annuals, plant them in late winter to leave plenty of time to develop buds by midsummer and fall. For growing artichokes as a perennial, sow them during late summers and early winters.
How to Plant Artichokes from Seeds
Are you ready to start planting your artichoke seeds? Learn how to effectively plant these herbaceous plants by following this simple guide.
- Start seeds indoors in seed starting trays, at least 6-8 weeks before the last spring frost date.
- Sow artichoke seeds ¼ inches deep and about 2-3 seeds per cell in the seed starting mix.
- For a faster germination process, soak the seeds overnight in warm water.
- Germination can take place between 10-14 days in temperatures ranging from 70-80 degrees.
- After 3-4 weeks, harden off the artichoke seedlings and transplant them to their final location.
Transplant Artichoke Seedlings
Artichoke seedlings can be either transplanted in raised beds or containers and pots. When transplanting the delicate seedlings, gently pull them from the seed starting trays after loosening the soil around them. Here’s how you can grow artichokes:
Grow Artichokes in Raised Beds
Transplant the young seedlings directly to the ground about 6 inches deep in rows with a space of 3-4 feet apart. Plant them when the temperatures are cool and frost-free in winters and mild and humid in summers. The average growing temperatures can be 50 degrees at night and 75 degrees during the day. You can also plant artichokes from dormant roots and shoots taken from mature plants.
Grow Artichokes in Containers
Artichokes are perfect plants for container gardening. They grow 3-4 feet in height and have a diameter of up to 6 feet, therefore, these plants need sufficient space to thrive. Transplant only one seedling per container which is at least 35-40 inches in size for healthy growth and harvest.
Artichoke Growing Tips
To harvest fresh tender artichokes from your garden, follow these simple growing tips.
- Artichokes are water-loving plants; they require a lot of watering and moist soil to develop firm buds.
- For best results grow artichokes in well-draining, fertile soil. Maintain a neutral soil pH (6.5 and 7.0).
- Use natural mulch or vegetable garden cover to retain moisture and ward off insects.
- Avoid mulching when they begin to bud, and instead use compost around the plants.
- For an extra boost, use balanced fertilizers.
- Full sun can aid in healthier and firm flowering buds.
- If pests and diseases such as aphids, flea beetles, powdery mildew, and bacterial crown rot are detected, use organic insecticides and sprays.
When to Harvest Artichokes
The ideal time to harvest artichokes is 80-100 days after transplanting. You can harvest them when the flowering buds emerge and are at their maximum size. The buds have to be swollen and the bracts shut tight for a successful harvest. If they are open, then you have missed your harvesting window. Use a sharp knife to cut the artichoke stem about 1-2 inches below the bud.
