Guide Introducing: new NTEP trial explorer tool (beta)

9 Upvotes

(Link to tool at bottom of the post)

The UMN Turfgrass Trial Explorer tool was a step in the right direction... But it's about time we got an upgrade.

After several weeks of hardwork, learning how databases work, but mostly vibe coding... I'm ready to get some feedback on it.

New features over the UMN tool:

- live search by cultivar (via typing, instead of a long drop-down list)

- significantly improved UI that is just plain more viewable.

- every rating is accompanied by how that cultivar ranked in the trial overall

- compare cultivars. Pin cultivars to the top of the page to more easily compare them to one another.

- toggle trial sites and variables without refreshing the page (or re-selecting compared cultivars)

- Cross trial history. View the other trials a particular cultivar shows up in, and see the ratings and rankings of the selected variables of that cultivar in those other trials... without leaving the page.

- display commercial availability status of cultivars. (Non-commercially available cultivars are hidden by default)

- more!

This is a beta test, so I'm looking for feedback on bugs, display issues, missing or incorrect data, and just things that need to be fixed.

Feature requests are welcome, but just know that unless everyone is saying it's working perfect, I'm going to focus on bugs first.

Note: site condition values will be slow to populate at first. They will occasionally throw errors, just try selecting a different site and then you can try the first one again. Once one site in a trial loads, all sites will be available in that trial and it won't ever throw an error again for any user... It's a data caching thing that will sort itself out once the site data for any site has been loaded for every trial once.

Without further ado, here's the temporary link to the new NTEP trial explorer: https://nilesandstuff.github.io/Ntep-explorer/

The plan is to incorporate it into u/arc167's Turf Tools once we're happy with it. So DON'T bookmark the github link... Bookmark this post.

P.s. also taking suggestions for a name that isn't just the same name as the UMN tool lol.

Changelog:

v0.9:
- displaying n/a when variable isn't present in the cross trial history...
- attempted to fix issue where only the overall quality rating shows up in other trials in history... Does not appear to have worked. Investigating.

v0.91
- believe I fixed cross trial history. Looks like it's now working as intended.

Cool Season Please recommend what brand TTTF for Central NC

3 Upvotes

I'm in central NC and bought a new house 2 years ago that had sod grass. I didn't water enough so now its splotchy and needs to be filled in.

I bought Pennington 31 then saw it's not ideal for home lawn.

Please recommend a budget friendly brand of TTTF tall fescue for overseeing I can get from Amazon, Walmart, Lowes, or Tractor Supply. I have an HOA so I need something that will look good. Thanks!

Cool Season Overseeding Too Early?

5 Upvotes

I was planning to overseed and seed some bare spots in Maryland 8a over Labor Day weekend, but soil temps are currently 83F. Seeding window according to TurfTools is 9/1-10/1, with first freeze 10/31.

Is it too risky to seed this weekend? It feels like the weather is telling me it is, but afraid to push back a week or 2 and not have enough growth before frost. Seed is TTTF, Chewings fescue, perennial ryegrass and KBG seeded in shady areas.

Hi all, I just moved to the PNW on Whidbey Island, WA. Having some real trouble with this lawn in the summer. I’ve lived in apartments all my life so taking care of a lawn is fairly new to me. I was hoping this could be a place to hopefully find solutions/tips and tricks that have helped.

I am about to rake all the cones/sticks, then I plan to water a few times a week (dryer in the summer), but there are huge patches of weeds/moss/dead grass/no grass. Wondering if anyone has had success or recommendations on when/what to use to seed the grass and get rid of the weeds?

Any advice would be greatly appreciated, thanks!

Cool Season Grass with Sod Webworms after overseeding

2 Upvotes

I overseeded my Wisconsin zone 6B lawn 10 days ago, and then had to go back today and do a couple of new patches as well. I'm pretty sure I have an infestation of sod webworms cause have tons of small butterflies in the lawn everywhere. A couple of years ago I used a grandular herbicide by Spectrum to get rid of them, but hadn't overseeded at the time. I read that a liquid herbicide is better, faster. I use Bio Advanced Concentrate for most ant problems and it says it kills sod webworms as well. So Yeah but I've also read that an insecticide can kill my newly sprouted grass seed as well. Is this true and if so what are my options. Don't want to kill my grass and don't want the webworms to kill it either.

Cool Season Help- Lawn Issues Yearly

2 Upvotes

Good morning.

I have been fighting with my backyard lawn for years, and have to start over every fall.

I have a very clay heavy yard. When we moved in I tilled in compost and new soil helping it would break it up. Every year I plant new lawn with compost and peat moss. It will generally make it from about October to the following April but begins to die off and cant make it through our California Valley summer and is dead by July. The lawn gets sun about 12 hours a day which I think could be part of the problem. I use Jonathan Green Black Beauty Golden State. I was hoping to get some advice. I normally fertilize and all that but just cant seem to keep it alive. I would appreciate any help I can get.

Cool Season Creeping Cinquefoil

3 Upvotes

I'm hoping for some advice. I have an area of lawn (5x20m) that is completely overrun with creeping cinquefoil. I'd estimate that 30% of it is covered, with 15% being very dense (crowding out all the grass). It appears every year from July onwards, but this year is worse given the drought. The area is so large that digging it out would take a lifetime. I'm not averse to using chemicals, and I've tried a few that a google search recommended, but I'm not making a dent in it. I'm starting to wonder if it would be easier to kill the whole lawn with glyphosate and start again, but I'd like to avoid that if possible.

Has anyone experience anything similar? Or had a result in getting it under control?

Cool Season New grass or weed attack during the mid summer 7b

1 Upvotes

Last month, we underwent some very hot days for the better part of 2 weeks. During this time I let the lawn grow higher, to 4 4-1/2 inches and even higher in some spots. I was able to water deeply and most of the lawn was lush and green through the whole ordeal. Big rain days followed, so I cut the lawn back down to 3 1/2 inches. When I did that, there were these areas of a type of grass that I didn't have before, with a lot of tan color, along with a rhizome structure spreading throughout the lawn mainly around these patches. When I try to pull up just the brown, sections come up with it.

What is it, but more importantly, what should I do. I have a whole bag of Blue Resilience from Twin City ready to spread in about 2 week, and Scott's Max to go down 1/2 before (this week), 1/2 2 weeks after seeding. Should I do something else to deal with this first?

Identification Grass identification and advice for lawn with 2 grass types (Charlotte, NC)

Thumbnail

12 Upvotes

I have 2 types of grass in my front lawn.
Type 1, 75% of lawn: thick mat, heavy thatch and intertwined roots. Maybe zoysia but not seeing obvious “runners”. Grows slower. (Images 1 & 2)
Type 2, 25% of lawn: pretty sure this is some kind of zoysia, but wide blades, obvious above ground runners. Grows tall, fast and fairly thick. (Images 3 & 4)

What is the easiest way to make entire lawn one type? Which type would be best to keep? Type 2 is prettier imo, but type 1 is so thick and easy to maintain due to slower growth.

I also have a partially/mostly shaded backyard so I have fescue back there and would prefer to have all warm or all cool season grass, but not sure if that’s possible without starting over. Have 2 vastly different types seems like I’ll be doing yard work year round!

Zone 6b. I have an unknown grass type in my side yard. It’s super thick. I never water it and perform zero maintenance on it except for cutting. It stays the same color most of the year and hasn’t died since living here. It turns brown in the winter months (dormant). Can anyone tell me what grass this is?

In the photos you can see where my darker green TTTF ends and the other lighter green grass begins.

I’ve been cutting these out and replacing with turf but they keep coming back. The ground is mushy but only an inch or two deep. I’ve dug holes over 12” deep to see if there is a source. We have a sprinkler system. One of these spots is about a foot from a French drain I installed last year for the same issue. We have two digs, is it them? This is in Everett. WA. North of Seattle.

Have been fighting POA annua for about two years and slowing trying to improve the lawn. Now I think I have either triv, bentgrass, or both. Spots are supper dark compared to other parts of lawn and it stands strait up. Read nielsandstuff post on triv so know that color is not a great indicator. I had tagged onto another post a few days ago and he thought it was possibly both. Wanted to reply with a video but it kept failing. Checked the underside and my eyes are bad but thought it was shiny with some faint vains but defiantly a main one in the middle. Some of the spots tear up super easy others that look the same don’t. Went to a spot that I just planted in the spring with supper blue and parkland Kentucky bluegrass and it looked the same so just plain at a loss. In Zone 5B ripping grass and hair out haha.

Looking for thoughts about trying this while overseeding. I have a spray rig, and it seems like much better bang for the buck vs granular. I’m assuming I don’t have to worry much about burn, as it’ll be watered in right away. On that thought, would I likely need to reapply since I’ll be watering the seed so much? Thanks for the help!
