You'll come back out about 45 days after planting to thin again, if needed. You'll come out about 20 days later to thin carrot seedlings to give the remaining plants plenty of room to grow their taproots. Let's say you're planting your first round of Danvers carrots in early March. Carrots should be ready for harvest about 60-80 days after sowing seeds, depending on the variety. The time-to-harvest estimates from seed companies are usually pretty accurate within 10 days or so, especially when the weather has been ideal. Making note of this date on your calendar can give you a good idea of when to expect your first harvest. It's kind of like how I always think I can assemble furniture without reading the directions. I know, this one seems obvious, but I have a bad habit of forgetting to check the back of the seed packet at the time of planting something.

Please refer to E-434, "MSU Weed Control Guide for Field Crops," for herbicide recommendations.Ĭan serves as an alternate host for aster yellows, which can cause losses in cultivated carrot crops. Sequential herbicide applications may be necessary for control. However, once wild carrot becomes established fall herbicide applications are more effective. Planting date: Most likely will not affect wild carrot infestations.Īpplication timing and effectiveness: Spring applications of labeled herbicides are effective in controlling seedling wild carrot. A single clipping in July has been shown to stop seed production.Ĭrop rotation: Mostly a problem in rotations that have little soil disturbance (no-till and perennial crops). Frequent mowing reduces wild carrot size and seed production. Mowing: Susceptible to mowing or clipping at the flowering stage. Tillage: Uprooting, chopping, and then burying the taproots will control wild carrot (that is why wild carrot is not a problem in tilled cropping systems). Wild carrot roots can be attacked by maggots of carrot rust fly, lesion nematodes and root knot nematodes. Lygus plant bug species nymphs can destroy the embryos of wild carrot seed. Dairy cow consumption of wild carrot in large quantities will taint milk. Predation/grazing: Sheep, horses, and cattle will graze on wild carrot. Grows on well-drained to dry soils, with low to moderate soil fertility.� Moderately competitive, dependent on wild carrot populations. Longevity: Seeds can remain dormant in the soil for several years.ĭormancy: Initially dormant, by 6 months 20% of wild carrot seed germinates. Some seed will be dispersed short distances by wind or longer distances by animals (hooked spines of seed attach to fur). Production Range: One plant can produce between 1,000 to 40,000 seeds.ĭispersal Mechanisms: When seeds are mature the dry umbel (flower) flexes outward releasing seed, the umbel then closes under damp conditions. Mode(s) of Reproduction: Reproduces by seed. Most seeds germinate from 1/4-inch soil depth, however wild carrot can germinate from depths of 4-inches. Some plants may act as an annual and flower in the first year. Forms a basal rosette of leaves the first year and an erect flowering stalk the following year, flowering occurs from July to September. Emerges primarily in spring, but also in summer and fall.
