NJ Lawns Community

I'm a first-time homeowner in Paramus and I'm losing my mind lol. Every single neighbor gives me a different answer on when I'm supposed to kick off spring lawn prep. Rob down the street goes on about 'when the forsythia blooms, that's your sign!' But then Maria on the other side of me insists I NEED to wait until soil temps hit 55 degrees. And my dad? He's like 'just wait until May, don't rush it.' ITS APRIL ALREADY. My lawn looks like a disaster and I have no idea who to listen to. Can someone just tell me what actually works in Bergen County?? I put down tall fescue last fall and I don't want to mess it up.

Oh man I feel your pain so hard. I've been doing this for 12 years in Englewood and the forsythia thing is honestly pretty solid BUT it's not exact science. Here's the thing - forsythia blooms when it's consistently around 50-55°F OUTSIDE air temp, which usually lines up with soil warming up too. But some years it's early, some years it's late. I personally go by the 50/50 rule - when daytime highs stay above 50 consistently AND you've had a few dry days to let the ground dry out a bit. Last year was weird, I started end of March because it was unseasonably warm. This year? I'd wait until at least mid-April honestly. The soil is still pretty cold.

Landscaper here who's been working Bergen County for 15+ years. The reason you get conflicting advice is because all three methods have some truth to them, and the 'right' time actually depends on YOUR specific conditions. Forsythia blooming is actually a pretty reliable biological indicator - it Flowers when soil temps hit ~55°F, which is EXACTLY when cool season grasses (tall fescue, KBG) start waking up. Your dad's 'wait until May' advice is way too conservative though, you're losing valuable growing time. My recommendation: Grab a cheap soil thermometer from any garden center. When you're reading 55°F at 4 inches deep AND the ground isn't soggy, you're good. For most of Bergen County (Paramus area especially with our clay soil), that's usually mid to late April. Don't aerate if the soil is saturated though - you'll make it worse.

Okay so the soil thermometer is the move?? I didn't even think of that. There's a garden center on Route 17 somewhere, probably worth stopping. Question though - once I determine it's time, what's the actual order of operations? Like do I mow first? Dethatch? Put down pre-emergent? I got a bag of Scott's Turf Builder with weed preventer but I don't know when that's supposed to go down relative to everything else.

The classic rookie mistake is putting down weed and feed too early lol. Pre-emergent needs to go down BEFORE crabgrass germinates, which is typically when soil hits 60°F. In Bergen that's usually around late April/Early May. Here's my annual顺序: 1. Clean up debris/sticks first mow (blade at 3.5") 2. Hit any bare spots with patching soil + seed if needed (fresh seed needs to germinate before summer) 3. First fertilizer app WITH crabgrass preventer around late April 4. Wait 6 weeks then fertilize again If you're seeing dethatching needed, rent a power rake from the rental place in Hackensack. Running it now should be fine since your fescue is established.

Adding onto the above - don't overthink the seed thing. Tall fescue is already pretty aggressive and should fill in on its own this spring. Only spot seed the really bad bare patches. One thing nobody mentioned: check your mower blade sharpness BEFORE the first mow. Dull blades tear grass instead of cutting it, and that creates all kinds of problems for healthy growth. I sharpen mine at the beginning of every season - there's a guy at theBergen County Garden Center in Hackensack who does it cheap if you don't want to do it yourself. Good luck this season! Once you do it a couple times it'll become second nature. The neighbors mean well but everybody's lawn is different.
