20 Jul Fall Alfalfa Planting
Fall alfalfa planting can be quite successful and offer stand establishment advantages over waiting until next spring:
- Weed competition in late summer planted alfalfa is usually less than spring planting. Fewer weed seeds will sprout in late summer, and most annual weed species won’t survive the winter.
- Alfalfa stand establishment in late summer and early autumn provides enough root reserves for a strong first crop yield next spring…you can’t get that in the establishment year of spring-planted alfalfa.
- Opportunity to take advantage of good late summer planting weather, instead of taking your chances on wet soils the following spring with potential planting delays and reduced establishment year yields.
- Better soil conditions in late summer can allow for tillage with less risk of compaction.
Clear seedings of alfalfa without a nurse crop are often most successful in late summer. Increase your success with late summer and fall alfalfa planting by paying attention to a few management practices. Make sure you have enough soil moisture for seed to germinate and sustain small plants after seedling emergence. Plant at least six weeks before a killing frost…eight to ten weeks is even better. Don’t clip alfalfa during fall establishment; fall clipping makes alfalfa more prone to winterkill.
