How to Plant Artichokes

Seeding and Germinating Artichoke Seeds

Artichokes are grown from seeds, which can be started indoors in late winter or early spring. Fill seed trays with moist potting soil and place one or two artichoke seeds in each cell, covering them with ¼ inch of soil. Keep the soil moist and warm, at around 70°F, until the seeds germinate in about 7-14 days. Once the seedlings have grown their second set of leaves, they can be transplanted into larger containers or directly into the garden.

Best Soil and Sunlight Conditions for Artichokes

Artichokes prefer well-draining soil that is rich in organic matter, with a pH between 6.5 and 7.5. They also require full sun, meaning they should receive at least 6 hours of direct sunlight per day. If your soil is heavy or clay-like, add compost or other organic matter to improve drainage and nutrient content. If you live in a hot climate, consider planting artichokes where they will receive afternoon shade to prevent sunscald.

Artichoke Seed Spacing

When planting artichoke seedlings, space them at least 3 feet apart in rows that are also 3 feet apart. This will give them plenty of room to grow and spread out. If you are planting multiple rows of artichokes, leave enough space between the rows for easy access and maintenance.

Planting Artichokes in Your Garden

Preparing Your Garden Bed for Artichokes

Before planting artichokes in your garden, it is essential to prepare the soil properly. Artichokes thrive in well-draining soil that is rich in organic matter. Start by selecting a sunny location that receives at least 6 hours of sunlight per day. Remove any weeds or debris from the area and loosen the soil with a garden fork or tiller to a depth of at least 12 inches. Add a 2- to 3-inch layer of compost or well-rotted manure to the top of the soil and mix it in thoroughly. Artichokes prefer slightly acidic soil with a pH between 6.0 and 7.0, so adjust your soil pH if necessary.

How to Transplant Artichoke Seedlings

Artichokes can be started from seed indoors or purchased as seedlings from a nursery. If starting from seed, sow them indoors in late winter and transplant them into your garden once the soil has warmed up in the spring. If purchasing seedlings, wait until after the last frost date in your area before planting them in your garden. Space artichoke plants at least 3 feet apart and plant them at the same depth they were growing in their pots.

When transplanting artichoke seedlings, be sure to water them well before digging them up. Carefully remove them from their pots or trays and gently loosen any roots that have grown around the bottom of the container. Place each seedling into a hole in the prepared soil and backfill with soil, tamping it down gently around the base of the plant. Water each seedling thoroughly after planting.

Companion Plants for Artichokes

Companion planting is an excellent way to maximize space in your garden and improve plant health by attracting beneficial insects and deterring harmful pests. Some excellent companion plants for artichokes include:

  • Garlic: repels aphids and other pests
  • Basil: improves the flavor of artichokes and attracts bees
  • Nasturtiums: attract beneficial insects and deter aphids and other pests
  • Cilantro: attracts beneficial insects and repels harmful pests

Avoid planting artichokes near plants in the cabbage family, as they are susceptible to the same pests and diseases. Instead, opt for companion plants that offer different benefits to your garden ecosystem.

Save Your Artichokes: Common Pests and Diseases to Watch Out For

Caring for Artichokes

Watering and Fertilizing Artichokes

Artichokes require consistent watering, especially during the first year after planting. They need a deep watering at least once a week, and more frequently during hot and dry spells. To avoid waterlogging, ensure that the soil is well-draining. A layer of mulch around the plants can help to retain moisture in the soil. Artichokes also require regular fertilization to promote growth and ensure good yields. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium is recommended. Apply the fertilizer every six weeks during the growing season.

Common Pests and Diseases

Artichokes are relatively resistant to pests and diseases, but there are a few issues to watch out for. Aphids can be a problem, especially in hot weather. These small insects feed on the leaves of the plant and can cause damage if left untreated. A strong spray of water can help to dislodge them, or you can use an insecticidal soap spray. Artichokes are also susceptible to fungal diseases such as powdery mildew and rust. To prevent these diseases, ensure good air circulation around the plants by spacing them properly and avoid overhead watering.

Harvesting and Storing Artichokes

Artichokes are ready for harvest when the buds have reached full size but before they start to open and bloom into flowers. Cut the buds off the plant using a sharp knife, leaving a short stem attached. The lower buds on the plant will mature first, so begin harvesting from the bottom up. Artichokes can be stored in the refrigerator for up to a week. To prepare them for cooking, remove any tough outer leaves and trim the tips of the remaining leaves with scissors. To prevent discoloration, rub lemon juice over any cut surfaces.

Storing Artichokes for Maximum Freshness

Best Time to Plant Artichokes

Planting Artichokes in the Spring

Artichokes are a delicious and nutritious addition to any home garden. When planting artichokes in the spring, it is important to consider the soil temperature. Artichokes prefer soil temperatures between 60 and 65°F. Wait until the soil has warmed up to this range before planting. In most regions, this will be around mid-April to early May.

When planting artichokes in the spring, it is also important to choose a location that gets plenty of sunlight. Artichokes require at least 6 hours of direct sunlight per day to thrive. They also prefer well-draining soil with a pH level between 6.0 and 7.5.

Planting Artichokes in the Fall

Planting artichokes in the fall can be a great option for gardeners who live in areas with mild winters. In these regions, artichokes can be planted in late summer or early fall, around September or October.

Fall-planted artichokes will have a longer growing season, which can lead to larger and more flavorful harvests. However, it is important to protect the plants from frost and cold temperatures during the winter months. Mulching around the base of the plants can help insulate them from the cold.

Regional Planting Times

The best time to plant artichokes will vary depending on your region and climate. In general, artichokes do best in regions with mild winters and cool summers. They are commonly grown in coastal regions of California, where temperatures rarely dip below freezing.

If you live in a colder region, you may need to start your artichoke seeds indoors and transplant them outside once the weather warms up. Alternatively, you can try growing artichokes as an annual crop, planting them in the spring and harvesting them before the first frost.

Unexpected Ways to Use Frozen Artichokes

By following these tips and considering your local climate, you can successfully grow delicious artichokes in your home garden. With a little bit of planning and care, you can enjoy the unique flavor of fresh artichokes throughout the growing season.

Artichoke Varieties for Home Gardening

Globe Artichokes vs. Jerusalem Artichokes

Artichokes are a tasty and nutritious addition to any home garden, but not all artichokes are created equal. There are two main types of artichokes that are commonly grown in home gardens: globe artichokes and Jerusalem artichokes. Globe artichokes are the more common of the two and are the ones you're likely most familiar with. They produce large, spiky flowers that are harvested before they bloom. Jerusalem artichokes, on the other hand, produce small yellow flowers and tubers that look like ginger roots.

If you're new to gardening, we recommend starting with globe artichokes as they are easier to grow and maintain. Jerusalem artichokes can be a bit more challenging to cultivate and require more space in your garden.

Best Varieties for Your Region

When it comes to choosing the best variety of artichoke for your region, there are a few factors to consider. Some varieties are better suited for cooler climates, while others do better in warmer temperatures. Here are a few options to consider:

  • Green Globe: This is one of the most popular varieties of globe artichoke and is well-suited for regions with mild winters.
  • Purple Sicilian: This variety produces beautiful purple flowers and does well in both warm and cool climates.
  • Colorado Red Star: This variety is known for its large, flavorful buds and is a good choice for gardeners in colder climates.

Make sure to do some research on which varieties will grow best in your specific region before planting.

Starting From Seed vs. Buying Seedlings

When it comes to planting artichokes, you have two main options: starting from seed or buying seedlings. Starting from seed can be a bit more challenging, but it also gives you more control over the growing process. If you decide to start from seed, you'll need to start them indoors in late winter and then transplant them into your garden in the spring.

If you're new to gardening or simply want to make things a bit easier, buying seedlings is a good option. This allows you to skip the seed-starting process and get right to planting in your garden. Just make sure to buy seedlings from a reputable nursery to ensure that they are healthy and disease-free.

Common Mistakes to Avoid

Over- or Under-Watering Artichokes

One of the common mistakes made by beginner gardeners when planting artichokes is either over or under-watering the plants. Artichokes require regular watering, especially during hot weather. However, too much water can cause the plants to rot, while too little can cause them to dry up and die. The best way to avoid this mistake is to ensure that the soil is moist but not waterlogged. This can be achieved by watering the plants deeply once or twice a week, depending on the weather conditions.

Planting Artichokes Too Close Together

Planting artichokes too close together is another mistake to avoid. While it may seem like a good idea to save space, overcrowding can lead to stunted growth and poor yields. Artichoke plants require plenty of room to spread out and grow, so it is important to give them enough space. Ideally, each plant should be spaced at least 3 feet apart in all directions.

Not Pruning Artichoke Plants

Another mistake that many beginner gardeners make when planting artichokes is not pruning the plants properly. Pruning is essential for maintaining healthy plants and encouraging maximum yield. The best time to prune artichoke plants is in late winter or early spring before new growth appears. During this time, remove any dead or damaged leaves and cut back the remaining leaves by about half.

Final Tips for Growing Artichokes

How to Overwinter Artichoke Plants

Artichokes are typically grown as perennials in warmer regions, but in colder areas, they can be grown as annuals. If you live in an area where winters are harsh, you'll need to take some steps to protect your artichoke plants during the cold months. Before winter sets in, prune your artichoke plants back to about six inches tall. Then, mulch heavily around the base of the plant with straw, leaves, or other organic materials. This will help insulate the roots and protect them from freezing. You may also want to cover your plants with burlap or other breathable fabric to protect them from the wind.

Using Fertilizers in Artichoke Cultivation

Artichokes require a lot of nutrients to grow well, so it's important to fertilize them regularly. Before planting your artichokes, work some well-rotted manure or compost into the soil. Once your plants are established, you can fertilize them every two to three weeks with a balanced fertilizer that's high in nitrogen. You can also side-dress your plants with compost or aged manure throughout the growing season to provide additional nutrients.

Troubleshooting Common Artichoke Problems

Artichokes are generally easy to grow, but like any plant, they can run into problems from time to time. One common issue is aphids, which can be controlled with insecticidal soap or neem oil. Another problem is powdery mildew, which can be prevented by spacing your plants far enough apart to promote good air circulation and watering them at the base rather than overhead. If your artichoke plants are not producing well, it may be because they're not getting enough sun or nutrients. Try moving them to a sunnier spot and fertilizing them more often.
