![]() Not all seeds need light to germinate, but some do. Make little adjustments as needed and you’ll easily sprout seeds into plants. These, you control with the right attentiveness and tools. The conditions in which seeds are started have a direct impact on the rate of germination. Germination Conditions Need Adjustment Are your seeds not germinating? We may have an explanation! Source: hello-julie Let’s learn about starting seeds in conditions that will contribute directly to your success in the growing season. Sometimes you get everything right, but some external force snacks on your seedlings.ĭon’t lament if you’re dealing with problems when you are planting seeds for the upcoming season. Sometimes its conditions present during seed germination, such as the growing medium, and sometimes it’s the seeds themselves. We’ll discuss ways to mitigate some of those issues, so you can germinate with an informed perspective on what could happen. ![]() As you continuously help seeds germinate, you’ll learn as you go.īut we’re here to address problems that may arise in the seed germination process. Germinating seeds is a process that may surprise you. An entire organism emerges from just one seed. Issues arise when you first learn seed starting.īut it’s not the end of the world. The seed germination process is fraught with many different elements. A lot goes toward the time to plant seeds. There is a learning curve between transplanting starts and helping seeds germinate. If an alfalfa stand is more than one year old, don’t attempt to reseed for at least one year.If I told you I’d never had problems with seeds not germinating, I’d be lying. ![]() You can reseed immediately into a failed spring seeding (or from the previous fall). If you are reseeding into a previous alfalfa stand, you need a waiting period to make sure all toxin is degraded out of the root zone. Use the higher seeding rate when soils are on the dry side.ĩ. Alfalfa plants produce a toxin that can reduce root development and survival of new seedlings. Summer seedlings can be susceptible to loss under dry conditions. Seedling diseases are not as important in the late summer seeding as for spring seeding, but major diseases and winterhardiness are still key factors for persistence.Ĩ. Plant alfalfa at 15-18 lbs. Plant winterhardy, disease resistant varieties.ħ. Choose varieties that are resistant to all major alfalfa diseases in your area. Press wheels behind a drill give the best stand establishment. Pack soils firmly to help control seeding depth. Once worked, soils will dry quicker in late summer. For light or sandy soils, seeds should be place at 1⁄2 to 3⁄4 inch deep. New seedlings may emerge, but can die within a matter of days from heat and droughty soils.Ħ. Ideal planting depth for alfalfa in clay or loam soils is 1⁄4 to 1⁄2 inch. Avoid planting alfalfa seed into extremely dry soil with little chance of rain in the near-term forecast. If a companion crop is needed for erosion, control plant oats at one-half bushel per acre.ĥ. At this time of year, any competition will risk seeding failure. Companion crops compete for sunlight and moisture. Maintaining P levels is critical to proper root and seedling development, while K increases yields and stand persistenceĤ. The optimum pH level is 6.8, and liming should occur 6 to 24 months prior to planting. Before summer planting, have your soil tested, and follow lime and fertilizer recommendations for phosphorus (P), potassium (K), and sulfur (S). Use of a glyphosate tolerant alfalfa variety gives you additional options for weed control after establishment.ģ. Use a burndown herbicide like glyphosate to control perennial weeds or volunteer small grains prior to planting.
