Celtiane organic potato - size 25/32

Potatoes will be back in January 2025!

The Celtiane potato; the Breton firm-fleshed, early to semi-early (85 days).

Famous for its firm flesh and thin skin, the Celtiane offers an abundance of beautiful, elongated tubers with very thin skin and yellow flesh. The result of a cross between the Amandine and Eden varieties, this potato has inherited the culinary qualities of the former and the productivity of the latter.

With its firm, flavorful flesh and good cooking properties, this potato is ideal for boiling or steaming to accompany raclette or salads.

Available in nets of 25 plants, 1.5 kg.

Growing Celtiane potatoes

Grow potatoes in a sunny spot in the vegetable garden, as in the shade the foliage withers and the harvest is small. Choose light, easy-to-work, deep soil. If necessary, lighten heavy soils by adding mature compost or potting soil, then fertilize with well-decomposed manure before planting.

Plant potatoes when the soil is sufficiently warm (above 7°C) and frosts are no longer a threat, from March to June, depending on the climate. Late frosts can cause young shoots to wither.

Water only during dry spells, without wetting the foliage.

How do I germinate Celtiane potatoes?

Sprout potato tubers, or seed potatoes, 1 month before the planned planting date to ensure a good start to the crop.

Set up the potato plants in ideal conditions for them to develop nice, stubby sprouts:

• spread the tubers out in crates or trays, without overlapping them, with the "eyes", the points from which the sprouts will emerge, facing upwards;
• keep them in this position, if necessary, using folded sheets of newspaper;
• keep the racks in a bright, cool but frost-free place, between 7 and 15°C. Light is essential for thick, green sprouts.

At planting time, potatoes should have stocky sprouts of 1 to 1.5 cm.

How to plant Celtiane potatoes?

Plant potatoes in rows 60-70 cm apart:

• dig a furrow about 15 cm deep in each row, using a furrow cutter or hoe;

• place a tuber every 30 to 40 cm, sprout side up, in the furrow;

• Carefully cover them by a few centimetres, taking care not to damage the sprouts.

The soil set aside during furrow formation will be brought back around the potato plants as they grow, during ridging.

To improve potato yields :

• ridge potato plants when they reach 15 to 20 cm in height;
• mulch generously at the base of potato plants;
• hoe, if necessary, to limit weed growth, facilitate water penetration into the soil, and reconstitute ridges;
• water during dry spells, without wetting the foliage.

When to harvest Celtiane potatoes?

Celtiane firm-fleshed potatoes are harvested mainly in summer, in June and July.

How to store Celtiane potatoes?

After harvesting, carefully dry the potatoes before storing:

• spread them out on a sheet or in crates;
• leave them in a ventilated place, sheltered from light and humidity, for a few days;
• store them in silos, crates or crates, in a frost-free, dark place;
• check your harvest regularly and remove tubers showing signs of mould.

Potato pests and diseases

Like tomatoes, potatoes are susceptible to mildew. This disease thrives in hot, humid conditions, and once it appears, it's almost impossible to get rid of. Take preventive action to avoid infestation:

• water only in dry weather and do not wet foliage ;
• mulch crops;
• space plants sufficiently apart to ensure good aeration.

Certain insects, such as Colorado beetles, flea beetles and aphids, can attack potato foliage and cause serious damage. Monitor crops regularly to prevent infestation.

Potatoes can also be affected by internal blackening. This disorder is characterized by bluish-gray spots under the skin, varying in diameter. They can progress deep into the flesh of the tuber, and in the most serious cases result in black spots. Blackening develops when tubers have a high dry matter content and have been subjected to shock or pressure.
