Crop management
Because parsnisps take long to matur compared to to carrots, a farmer sows parsnips and carrots by broad casting over the soils or by planting in straight lines and this make thining easy. Plant crops of the edge of the garden and net them to keep dogs and birds out.
Similarly, sow onions between carrot rows, cover seeds with a small layer of soil and put parsnips in the fridge for at least 2 weeks before sowing to break dormany and increase germination. Plant parsnios quite deeper than carrots and also beetroot in the same garden and finally cover bed with micro climate to control animals and birds from garden.
