Growing Celeriac: A Gardener's Guide

Have you ever tried growing celeriac, also known as celery root? It's a fascinating plant that tastes like a cross between celery and parsley with a touch of nuttiness.

Getting Started: Seed Selection

Choosing the right seeds is crucial. I always opt for organic, non-GMO varieties.

One season, I experimented with 'Prinz' and 'Alabaster.' Both produced robust and flavorful roots.

Sowing and Germination

Starting Indoors

Timing is key. Start your seeds indoors about 10-12 weeks before the last frost date.

Fill seed trays with a light, well-draining potting mix. Sow seeds on the surface and lightly cover with soil.

Keep the soil moist, and place trays in a warm, bright area. Germination can be slow, taking 2-3 weeks.

Transplanting

When seedlings have two true leaves, they're ready for transplanting. Harden them off by gradually exposing them to outdoor conditions.

Plant them in your garden 12-15 inches apart in rows spaced 18-24 inches apart. They need room to grow!

Soil and Watering

Celeriac thrives in rich, well-drained soil with a pH between 6.0 and 7.0. I mix in plenty of compost to improve soil texture and fertility.

Consistent watering is crucial. Keep the soil evenly moist, but not waterlogged.

Tip: Mulching helps retain moisture and suppress weeds. I use straw or shredded leaves.

Feeding and Care

Fertilize sparingly. Too much nitrogen can lead to lush foliage but small roots.

I apply a balanced, organic fertilizer every 4-6 weeks during the growing season.

Pest and Disease Management

Celeriac is relatively pest-resistant, but watch out for slugs and snails. They can decimate young plants overnight.

To deter them, I sprinkle crushed eggshells around the base of the plants. Works like a charm!

Harvesting

Celeriac takes about 110-120 days to mature. It's ready for harvest when the root is the size of a softball.

I use a garden fork to gently lift the roots, being careful not to damage them. Trim off the foliage and store in a cool, dark place.

Storage and Usage

Celeriac stores well for several months. I keep mine in a root cellar or the fridge.

It's a versatile vegetable. I love using it in soups, stews, and even mashed like potatoes. The flavor is uniquely delightful.

Did you know? Celeriac is not only tasty but also packed with vitamins and minerals, including vitamin K, C, and phosphorus.

Final Thoughts

Growing celeriac requires patience, but the reward is well worth it. Each harvest is a reminder of the incredible flavors nature offers.

Happy gardening! 🌱

How Do You Grow Chinese Artichokes?

Most people have never heard of Chinese artichokes and may even be afraid to grow them. After all, who remembers a vegetable called an artichoke? These are small-leafed, heart-shaped edible thistles that come from the same family as brassicas like broccoli or cabbage. In fact, if you take broccoli and remove its outer leaves, it will look just like an artichoke. The only real difference is that Chinese artichokes grow in the ground while brassicas grow in pots indoors. Growing Chinese artichokes requires a little more effort than other vegetables but the rewards are well worth it. You can harvest the green leaves throughout the year instead of waiting for certain seasons. When grown organically, they also do not require any chemical pesticides or insecticides to control pest problems. These factors make growing Chinese artichokes a great choice for gardeners who value their time over convenience or those with limited space to grow food indoors as well as outside.

How Do You Grow Seakale?

Seakale is a cool-season vegetable that looks like snow peas. It grows as a biennial, meaning it flowers and then dies after producing the seed. Once the first year’s seed has matured, you can grow the second year’s crop using the same plant. The plant will not produce any seeds the second time around because the plant has already transferred its genetic material to make new plants so it can continue to grow and flower. Seakale grows best in well-drained soil in full sun, but it will tolerate partial shade as long as it receives plenty of direct sunlight. A sandy loam is ideal for growing seakale, while a clay loam will also work well. Seakale can grow as an annual, but most people choose to grow it as a biennial because they don’t have enough space for two years worth of crops per season.
