Carrot St. Valery (James Scarlet)

 Sow the seeds outdoors 3-4 weeks before the last spring frost or as soon as the ground can be worked.  Keeping the soil moist throughout the germination period is important for success.  It is recommended to mist the planted area daily or cover it.  Carrots are slow to germinate and need constant moisture until germination.  Thin out a first time to 4 or 5 leaves at 2 or 3 cm then at 7/8 cm. Hoe and weed regularly. Water in times of drought. Sow successively throughout the season to obtain fresh carrots.

 The onion, as well as the shallot, the leek or the garlic are beneficial to the carrot from which they repel the fly. Tomatoes, peas, lettuce and radishes provide a favorable environment for carrots. It is also advisable to sow a few radish seeds in the rows of carrots. On the other hand, avoid cultivating carrots alongside potatoes and dill.

 The  carrot fly  is its main parasite. The larvae of this fly dig galleries in the roots going down towards the tip. The biggest infestations occur in July-August. Foliage of affected carrots turns yellow and wilts. The best means of control remains preventive, in particular thanks to good marriages. Decoctions of tansy and lavender can also contribute to the prevention of this fly.
the  root aphid  can also damage the carrot. It can be removed using a  Anti-Aphids based on Pyrethrum , or by making a treatment based on  Nettle manure .
