Terroir: Zone 6A (Eastern MA), full sun, well-draining soil on a hilltop/granite
ledge, mix of KBG/Rye/Fescue, ~5000sqft total lawn area (no soil test yet).

Last Aug/Sep I transplanted a garden from the
middle of the front yard and seeded/applied started fertilizer to the newly
bare area. I also applied a high-N
fertilizer to the entire lawn on Thanksgiving per this site’s recommendations.

Issues: Thin/bare areas, moderate broadleaf
weed pressure, significant midsummer crabgrass invasions, damage from garden
transplant activity and foot traffic, pesky daylily remnants still growing in
transplanted garden area.

Mid-Feb 2017:
dormant over-seeded the entire lawn with 10lbs. SeedSuperStore “SS5000 Sunny
Mixture Premium sunny mixture for Northern lawns” in the more visible areas and 7lbs. “Scotts
Turf Builder Grass Seed - Sun and Shade Mix” in the high-wear and less visible
areas – the intent was to
allow the freeze-thaw cycle improve seed-soil contact.

Mid-March 2017: fertilized with 16lbs. “Scotts Turf Builder Lawn Food -
Starter Food for New Grass Plus Weed Preventer” ($36 from Amazon, NPK 21-22-4,
0.5% Fe, 0.08% Mesotrione (Tenacity)). I
had originally planned to go all Tupersan this year, but the price on this was
right. Works out to ~0.7lbs./1000sqft Nitrogen.

Mid-April
2017: fertilized with 15lbs. “Jonathan Green 10465 Crabgrass Preventer Plus New
Seeding Lawn Fertilizer” ($67 from Amazon, NPK 10-15-10, 3.5% Siduron
(Tupersan)). Works out to ~0.3lbs./1000sqft
Nitrogen.

Results so far look good. The seeded garden area had started out this
year much more green than the surrounding lawn (probably due to the extra shot
of starter fertilizer last fall), but the lawn around the seeded garden area has
come in pretty well to blend it in.

Very
few dandelions have come up as compared to previous years, and other broadleaf
weeds came up yellow and withered (probably from the Tenacity). I am spot-spraying the broadleaf weeds that
do come up with Weed B Gon for Lawns.

Question
1: What and when should my next
fertilizer move be? My plan was to do
another round of starter fertilizer with Tenacity in mid-May (and nothing else
until Thanksgiving).

Question 2: The transplanted garden area is still quite
lumpy and uneven, even though I carted in ~800lbs. of topsoil to level it out
last fall and tamped in down thoroughly. Should I top dress with sand or
topsoil to level it out?
