DIRECT SEEDING Establishing A Forest With Seed BENEFITS OF DIRECT SEEDING VS. TREE SEEDLINGS WHY DIRECT SEED? Larger Planting Window, Fall Season Utilize Local or In-State Seed Resource More Trees/Acre-Quicker Canopy-Form Undisturbed Root System/No Transplant Overwhelm The Critters

DIRECT SEEDING Establishing A Forest With Seed
WHY DIRECT SEED? • Larger Planting Window, Fall Season • Utilize Local or In-State Seed Resource • More Trees/Acre-Quicker Canopy-Form • Undisturbed Root System/No Transplant • Overwhelm The Critters • More Natural Appearance • Shorter Maintenance Period • Potentially Less Expensive
WHY PLANT SEEDLINGS? • Seed germination is uncertain, seedlings are a known quantity • There are more potentially damaging agents for seed than seedlings • Seed crops and seed availability are uncertain • Seedlings may have a head start the first year, depending on size and quality
SEED COLLECTION Determine your needs Scout potential seed trees Use a Bag-a-Nut Be efficient Float, sort/inspect, store
Tree Planting Plan, an attachment to NRCS Conservation Plan, will prescribe the seed per acre and match species to site. DetermineYour Needs, Match Species to Site
Scout Potential Seed Trees • Be sure of species ID • Locate on a large scale map • Red oak group visible in July, white by August • Obtain permission to collect
Using a Bag-a-Nut • Up to 1 bushel (about 50 pounds) per hour of medium-sized acorns • Can pay for itself in less than 8 hours • Works best in mowed grass situation, with some site prep • Match machine to seed size • For more info. see www.directseeding.org
Rakes Blower/vac Bag-a-Nut Containers soaking pool sorting table onion bags cold storage Be efficient, gear up before you start:
Be prepared: In central Illinois seed begins to drop late-August to mid-September White oak group is usually first, then red, pin drops late Concentrate on trees with a BIG seed drop Collect after windy storms Collect BEFORE leaves fall After leaves fall use blower/vac to remove leaves Be Efficient
Soaking Seed Sorting Seed
Purchasing Seed • Local seed is the best seed • Contact District Forester and/or SWCD • Check www.directseeding.org • Follow “Seed Care and Handling”
“Float” collected seed, soak ALL seed Immerse 4-8 hours Inspect at least 10 seeds/bushel If its your own seed inspect on the sorting table, before bagging Cut or crack test, look for seed that is: filled, light-colored, bug-free Bag in porous, woven (“onion”) sacks Store in cool, well-ventilated location, protected from predators If delayed more than 2 weeks, place in plastic bags and refrigerate @ 33-40 degrees Seed Care and Handling
Inspect All Tree Seed • Use a hand pruner for acorns, a hammer for walnuts & hickorys • Keep seed that is: • Filled • Bright, uniform color • undamaged • Discard seed that is • Shriveled, shrunken • Dark colored or mottled • Cracked, holed, or otherwise damaged
Use High Quality Seed • Plant only undamaged, mature, viable seed • Cut or crack test at least 10 random seeds per bushel • If non-viable seed is found, increase seeding rate by the same percentage
PLANTING TIME -ASAP, Fall is best -white oaks-must fall plant, especially Quercus alba & chinkapin -if properly stored, plant any time ground is not frozen or dry -very risky between June and September
Row Seeding MINIMUM of 3,000 hard mast seed/acre At 10’ row spacing, about 16” or less between seeds Planting depth about 2X seed diameter, 1-4” depending on species If no light seeded spp. nearby, add 1,000 seed/acre Seeding Rates
Broadcast Seeding MINIMUM of 4,800 hard mast seed/acre Planting depth about 2X seed diameter, 1-4” depending on species If no light seeded spp. nearby, add 1,000 seed/acre Seeding Rates
Till and/or spray a minimum 2-foot radius circle or 4-foot wide band with trees or seed centered in the grass free area. Grass species, esp. sod-forming, are death to trees. Use snap trap survey to estimate potential rodent populations. Site Preparation, Row Planting Mow or till between rows to minimize rodent habitat
Site Preparation, Broadcast • Crop ground • Disk Several Times • Pasture/Brome • Mow grass in August. • Spray 2 quarts of Roundup in September • Plow and Disk
WEED CONTROL FOR DIRECT SEEDING • Competition must be controlled for minimum of two years • Good control of grasses and weeds is critical
WEED CONTROL FOR DIRECT SEEDING 1st Year Pre-emergents Pendulum (Prowl) - 2qts/ac. Goal - 2 to 4 qts/ac. (expensive) Post-emergents Fusilade - grasses 6-10”; 1 pint/ac. plus a non-ionic surfactant OR Envoy - grasses < 12”; 1 pint/ac. Transline or Stinger - broadleaves; 1/2 pint/ac. See: IL Forest Herbicide Manual, IL Direct Seeding Handbook, & www.directseeding.org.
WEED CONTROL FOR DIRECT SEEDING 2nd Year Pre-emergents Pendulum (2 to 3 qts/ac). + Princep (2 to 4 qts/ac.) Post-emergents (weeds no more than 6-12” tall) Fusilade - grasses (1 pint/ac.) Transline or Stinger - broadleaves (1/2 pint/ac.) Oust - grasses and broadleaves (1/2 to 3/4 oz/ac.) See: IL Forest Herbicide Manual, IL Direct Seeding Handbook, & www.directseeding.org.
Maintain weed free area for 2-3 years Replant if survival drops below 500 after 2 years, counting desirable natural regeneration. Plantation Maintenance
A little late-season broadleaf competition is OK... Grass competition is a prescription for failure!

Use a professional Control weeds Match spp. to site Inspect all seed, carefully store & handle (cool & moist) Survey and manage rodent populations Use lots of seed Use lots of species Plant @ proper depth Keys to Success with Direct Seeding
