Parsnip seeds can be planted as early as spring in warm soil. Sowing: Grow the seedlings between April and May or middle to late June, when the ground is warm. Two to three weeks prior to the first frost of fall, soak all American parsnip seeds in water, leave for a few days, drain and then reseed overnight. The soil should be deeply worked using good quality garden soil.
Seed saving often occurs when seeds are grouped together so that they do not wither when exposed to adverse weather conditions, which often kill individual plants. However, this can be accomplished by sowing small amounts of one kind of seed at a time in large amounts, for example, when planting many small seeds of red and black peppers in a larger field of red peppers. After the area has settled, group the sown seedlings together with similar colors, as close together as possible. This type of seed saving results in better growth and taste of the resulting crop.
Three weeks after sowing the seedlings are ready to transplant into the garden. The distance from the seedling to the ground should be three weeks. One week before harvesting the parsnip seeds, they should be sprouting. Harvest them during the third week of growth. If they are not sprouting, transplant them into a new pot and replant the same number of plants you had originally planted.
Planting Germination of Parsnip seeds indoors requires adequate light, moisture, and warmth. Plant two sets of approximately twelve plants per square foot. The plant should be placed in the center of a two-inch thick layer of well-rotted garden compost. Be sure to include plenty of dark organic matter and water to encourage root development. The main difference between indoor and outdoor planting is the lack of wind. A small garden bed can be created with a one-inch thick layer of topsoil in the bottom, rich in nutrients, and six to eight inch deep carrots roots with roots already established.
Developing the Vegetative Structure Developing the herbaceous greens like carrots, daffodils, and anise hyssop is easy. The longer stems do not like being pollinated. The best way to develop these parsnips seeds indoors is to provide consistent light, temperature, and moisture. Make sure the soil is moist but not saturated. If a plant likes its pot full of moisture, it will grow well in your outdoors.
The Best Place Create a rich organic soil with coarse sand or gravel. The most favorable location is where the soil is rich in nutrients but is not heavy with weeds. Parsnip seeds will germinate in medium light to full shade. It is important to make sure the area you chose does not receive too much rainfall.
The Best Time to plant a basket garden of deep green perennial herbs like parsnips, daffodils, annato, and anise hyssop is during late spring through early summer. The cool weather allows for larger cankers and more growth than during the hot summer months. The cool weather also makes it less likely for cankers to sprout up. The most difficult weeds to manage during this time are ragweed, crabgrass, and any crabgrass roots that may be present. However, with persistent application of a natural herbicide, you will be able to control most of these problems. There are many commercial herbicides on the market that will control most of these perennial weeds.
How to Germinate If you are planting from seed, you should follow the same germination process that other herbs follow. Parsnip seeds should be placed in a shallow dish of water. The dish should not be deeper than is comfortable for the seedlings. Cover the seed with a thin film of plastic wrap. Keep the seedlings out of direct sunlight and moisture to keep the roots from drying out.
