Good luck but you won't win.

I needed to hit it last year when it first germinated…may alert the town. They make a halfhearted effort every summer to nuke it only for it to grow right back before fall. 

[ineedsnow]

well this is pretty interesting.. hopefully we can actually get a skillful model

It’s pretty bad here too. There’s a big patch of it down the road along a stream that feeds into the Winni River. Last year a patch sprouted up roadside halfway up my hill and I’m tempted to roundup that shit myself before it starts spreading.

Invasives, scourge of the earth. Especially around wetlands.

We used to have people cutting it and ripping it out of the ground each summer along the river but it was a losing battle.  Now it’s just taken over all across the banks for like 5 miles.

The new thing is to lay 1/2” hardware cloth over the area and let it grow through it. It keeps girdling itself as it grows. Not sure that would eradicate it with time though as it doesn’t need much photosynthesis to refuel the rhizomes.

It doesn't like shade, which is good. The 2 neighbors have it but we have about 100' of kinda swampish woods that keeps it away I think....for now. 

[kdxken]

That's going to leave a mark.

Invasives are a zero sum game. Blackberries take over a native meadow, multiflora rose takes over blackberry, porcelain berry takes over the multiflora rose. I do get a bit of satisfaction seeing anything take over multiflora rose. But In the end you lose.

Ha, I get 2 minutes of peas yesterday and I’m super excited.

Denver is like, hold my beer.

Dude it’s out of control along the river banks here.

The biggest problem I see, around here at least, is how well-intentioned homeowners unintentionally spread it. They cut it, bag it, and bring it to municipal compost sites, where viable fragments can get redistributed. Even mowing, cutting, or moving plant material can spread it if stem or rhizome fragments survive and easily reestablish.

I always wondered if the large scale effort to eradicate it here led to it spreading even faster.  It probably did.

There used to be a group of landowners with like machetes walking along the river through Stowe hacking the stuff down and collecting it.  Probably just led to it being washed downstream even faster or moved somewhere else.

I take great pride in not using pesticides on my property but two years ago I nuked the Knotwood along my property line and after a dormant year it has just exploded in that same zone. I hacked at it and left the remnants in the sun to bake, but it's concerning. I have several invasive species on the edge of the property, but that is by far the worst.

See above. Sometimes I feel like not using the chemicals just allows the invasive stuff expand but I have good biodiversity (I think) on my patch of land than neighbors. I'm very excited to see how the firefly population looks this year imby.

I helped my aunt eradicate some. It takes years and this is the method I used. You can also use triclopyr. 

The first step cannot be taken until late august/early September due to the timing of moving the chemical to the roots

1. Borrow injector gun from county if one is available. Fill it with *concentrated* glyphosate. Inject each knotweed stem below the first node. You may want some sort of paint spray to mark which ones you’ve sprayed

2. It will die off after step one, but the next year it will come back, much smaller. You can’t inject these stems anymore, so you spray the tops with glyphosate. Again, wait until august/sept. 

3. It will all die off again, and then very very few will pop up in the following years. You should continue to spray them individually in august/sept every year until they are completely gone. There will be very little to do as it will be only one or two plants popping up.

There is no other way to remove knotweed. You can’t cut it, you can’t mow it, nothing. Please do not compost it or transport it. You have to burn it once the stems have dried. It is ruthless because of its underground rhizome growth which can extend up to 10 ft below the soil surface. Don’t listen to anyone that tells you chemicals aren’t needed because you will waste time and likely spread it in the process of trying other methods. Remember that even a tiny piece can start a new plant.

Down to 38F this am in E CT, glad we haven’t installed yet! I think this weeks weather is going to be a microcosm of the summer, some cool days, some normal days with occasional 90 degree days thrown in; don’t feel like we see any prolonged warmth.

[CoastalWx]

30 MVY lol

[Baroclinic Zone]

Brrrr

39F

[kdxken]

Looks like a nice stretch incoming .

[Brewbeer]

With any luck the dew point with stay under 60 until Saturday

[dendrite]

Min 42.5°

Time to flush this

[Damage In Tolland]

It over . Ahhhh

[CoastalWx]

No real sign of prolonged heat.
 

[dendrite]

MAV for Thursday. Pretty warm.

so a hugely rangy summer then -

[Typhoon Tip]

I think today's gonna seem pretty warm W of I-95

Wouldn't be shocked if Scott to Ray sniff Labrador's nut sack in the afternoon. Such a weak gradient in place and the intensity of the 100% bake in the interior, seems they delay warm arrival by one last reach back face smack upon exit of this pattern. LOL.  

Or not... where not, MAV/MET MOS have both inched closer to 80 for today.  Right now they're 78 .. 79 around the BDL-FIT-ASH horn.  Testing that

[Typhoon Tip]

I don't think we've had "prolonged" heat here for years.   We've had heat waves, ...usually falling short of what they could have been when they do with just one day out of them that gets to 97..  Kind of like what happened earlier in May ... some with more or less DP to go along with.  But they're too many reasons to neg interfere.  

I'm beginning to think the return rate around here is so long there's no practical value in really looking much less waiting for them.   Those 97 for five days running over lows of 76 with 82 in the urban centers are Chicago to KC or NYC S.

ASOS can be so weird in rad pits lol. FOK, OWD, MVY, SLK, SFM… Often 10F colder than anything around them on rad nights.

FWIW I did see a 33 and 34 nearby on PWS.

Still winter

if you took a polar rotted January thermal profile and subjected it to June sun, you'd get that January sfc temp to be just like yesterday

[Torch Tiger]

No prolonged cool anytime soon

True

MEX MOS is 80 to 88 every day thru Saturday ( that includes Saturday ).  That's a 4 days of 80s?  Decent.

I was just musing with Scott that in principle we haven't committed to the warm season yet.  We've had heat, but until the basal return pattern state stops dipping lows below 40 this is a zombie winter.  

Imho of course... 

There's either a standard c-front (Euro) or a BD (CMC/GFS) late Saturday night and Sunday's on the cool side, but at this time ...the modeled air mass/thicknesses are not that 47 F shit.  More like bopping us back to 64. Could be wet, or it could be dry...then ,there's another warm push mid next week - that one looks more like a warm sector  

Don't have much of a bead on post 15th June yet

Wunderground? I didn’t look there yet. Only other ob I saw was 42°

I’m not saying it’s wrong. But a lot of these ASOS sitings don’t seem to represent the area.
