September Tall Fescue Pasture Renovation Tips

September is a critical time for Tall Fescue Pasture Renovation. If you don’t have your critical dates set, make decisions and put the dates on your calendar. Specific establishment calendars are available for most states on the Alliance website, or from your local extension agent.

A Novel Endophyte Tall Fescue stand planted in southern VA October 24, 2023. Picture taken September 8, 2024. This stand was grazed twice during the spring and summer and is now ready for fertilizer to stimulate fall growth.

For new stands to be planted this fall it is critical that fields are well prepared for planting, and that seed is put in the ground on a timely basis. If you used the Spray-Smother-Spray-Plant strategy, it is time to terminate the summer smother crop. It is important to minimize surface residue, so it may be advisable to remove the crop as hay. If grazed, make sure you graze it pretty hard so that all the material is either consumed by the animals or severely stomped. This will help the new seedlings to emerge and grow. After that final haying or grazing event, wait a few weeks (preferably following some rain) before spraying glyphosate and planting. Crabgrass residue is especially troublesome for tall fescue seedling emergence, so if there is significant crabgrass present graze it hard or hay it, and spray with glyphosate several weeks before planting to allow the residue to decay some.

If you are using the Spray-Wait-Spray-Plant strategy then you should make your first spray three weeks before your planting date. As with the smother crop system, make sure you have removed as much biomass as possible before allowing the pasture to grow a few weeks before spraying. It may be necessary to wait longer than 3 weeks if the weather is dry to allow for sprouting of any tall fescue seed or other weeds that might be present. If you want to establish Novel Endophyte Tall Fescue without herbicides, till the land thoroughly to kill all existing tall fescue and the summer annual before planting to novel endophyte tall fescue.

You should have ordered your seed from a reliable source. Novel endophyte tall fescue seed is now starting to arrive at seed dealers across the fescue belt. If you have not ordered, it is not too late as there is a good seed supply this year.

There is a new product approved to carry the Alliance for Grassland Renewal label: Triumphant Protek from DLF/Pickseed. The other proven varieties eligible to carry the Alliance label; BarOptima plus E34 from Barenbrug USA, Jesup MaxQ2, Lacefield MaxQ2 and Texoma MaxQ2 from Pennington Seed, , Estancia with ArkShield from Mountain View Seeds, and Martin 2 Protek and Tower Protek from DLF/Pickseed are all available and despite minor differences they are all good products.

For second year stands, graze or cut hay to remove summer growth of tall fescue and other volunteer summer grasses. Fertilize with nitrogen and allow to stockpile, or graze rotationally once fall growth starts to accumulate. If there were few weeds during the year and the pasture was not sprayed with a residual herbicide, then consider frost-seeding red and white clover during January after grazing stands down for the winter. If you had weeds then delay planting the clovers, and follow through with a weed control program next season.

In 2023 the entire tall fescue belt experienced a drought, so there were many fields that were planted late. These late plantings were surprisingly successful, so if you are very dry it is not a bad idea to delay until you have some moisture to plant into. It is getting dry across the region again this year, so watch the weather and hope for a better season than we had last year.
