Bindweed Info Dump

114 Upvotes

I have a large yard where almost no area is free of bindweed, and several areas are densely packed infestations. >_<; As spring comes, I dread the day my old enemy emerges.... Let's pool our knowledge! I've been fighting it for two years and doing a ton of research. Here's my info sheet: https://docs.google.com/document/d/1-bDNRYYo7yRIqAq6pUejPl6MIcFP8W9q1ZVYC99FZx8/edit?usp=sharing

Some highlights from that:
-Bindweed mites are best for dry/un-irrigated areas like vacant lots, and there's a long waitlist
-Pulling it stimulates growth (but if you can stay on top pulling it that helps to weaken it)
-It will grow up through, around, sideways whatever you try to cover it with. At least up to 20 feet sideways.
-Glyphosate and 2,4-D amine weed killer can be effective but not a guarantee by themselves.
-GOOD NEWS: Some Colorado folks have actually found success by planting perennial shrubs and grasses. Another great reason to go xeric!

What have you seen be successful? If anything, ha. Especially curious if you solved more than a small patch.

What have you seen fail? Even something that seemed like it should work? One person said it grew through a 20 feet pile of mulch.

Edited to Add: My neighbor said he found it successfully burrowing into concrete, for crying out loud.

16 pictured. Some may not be ready but the vines died last week from the overnight freeze so I went out and collected them all.

Had another two squirrels got into but I’m not complaining. They need food and I have plenty for the next few weeks.

Bolted Basil - Make basil salt

• Upvotes

So like many this year we all had fun with our basil bolting. Thanks to the recommendations I tried making Basil salt.

Basically 3 cups of basil flowers and leaves and 1 couple cups of whatever salt fits your fancy. Blend it up, if it is still wet, throw the mix on a pan with parchment paper and spread it out, cook at 150 to 190 for an hour or two until everything is dry. Throw the clumps of dried salt back in the processor. Boom done. Well worth it!

I tried the ice cubes and the olive oil and basil. It works well but it is a little messy and basil ice cubes are good for soups and it does work it just lost that snap.

So I tried it. And made the sweet basil salt. Worth it. Not so messy, the salt is awesome and it works on everything.

Have a great day! Enjoy the garden while you can.

What was your grasshopper experience this year?

20 Upvotes

Last year I posted here a couple of times about grasshoppers, including my conversations with the CSU grasshopper specialist. I attended a webinar she ran and was armed with information. Based on last year's numbers (horrific) and weather conditions, we were told to expect a statewide grasshopper apocalypse this year. I live on ranchland near Pueblo and expected decimation. Thankfully, it was a bust. Very few grasshoppers.

What did everyone else experience? Was it a bust? Did we all just prepare for a battle that never materialized? I'm very much ok with that but I've been wondering about other parts of the state.

The weather is confusing my iris. Many have 2 to 3 inches of new growth on the leaves already cut back. Do I cut them back again or leave them as is?

Overwintering sweet potato?

It took so long for this thing to grow vines that I don’t want to waste it. Hoping to make it last indoors this winter and then propagate some slips in the spring. Any recommendations?

How did everyone fare with the frost the last 2 days?

16 Upvotes

Wednesday and Thursday we tried to harvest anything and everything that looked ready to pick, then left the rest and crossed our fingers. I dug up some of the herbs I wanted to bring indoors.

This morning I went out to survey the damage.

Tomatoes: topmost branches and leaves are wilted, but at least 90% of the leaves and branches are perfectly fine. I have a LOT of green tomatoes that look just fine.

Tomatillos: most leaves are wilted but so far the branches look ok. I'm hoping the tomatillos fill out some more before we get our first true freeze.

Squash (zucchini, pumpkin, winter, yellow): leaves are all wilted. Vines still full and green. Squash look fine for now. Going to try to let them ripen some more.

Peppers: completely unaffected. Still happy and green.

Potatoes: vines and leaves all wilted. Can't wait to dig them up in a few weeks to see how many potatoes we get this year.

Vine for hot brick wall w/ requirements

13 Upvotes

Hi! I am looking for a vine type plant that is:

  1. Local/native
  2. Pollinator friendly
  3. Animal safe (dogs, cats, birds)
  4. Low water/high heat tolerant
  5. Reasonable effort

I have a section of my house that faces south, and is approximately 12' wide plain blonde brick. In the summer it gets so much sun that it contributes to more heat in the house and the yard. I would like to build a supportive trellis for vines to climb up that section and provide a barrier about 18" out from the wall to cut down on the radiant heat effect.

Because it's against the house, I don't want excessive water at the base (currently there is a rock bed in that area) so would love something that is more comfortable being in a full sun environment. Benign neglect is probably more my style in terms of care overall, as well. I would love flowers for the butterflies and bees and visual interest, but preferably not something that may become a nuisance in terms of destructive roots, or excessive detritus that could lure pests.

Dog and cat safety is the primary concern, though, as this is in my back yard, and my dogs and cats have access.

Is this a magical thing that doesn't actually exist? Am I dreaming? Help me Denver gardeners, you're my only hope!

(Located in Denver metro area, btw)

What to do with the dirt during the winter

Post image
12 Upvotes

I would like to have this be grass next year but am open to other suggestions. We moved in June and neglected watering the grass. I really want to plant some big trees along the fence for privacy from my neighbor. I’m looking into Juniper Wichita blue trees but am also open to recommendations on that. What do I do with this dirt area for the fall and winter? What is the best way to get it ready for grass next year?

Xeriscape vs Native vs WaterWise: What style do you use (and how do you describe it)?

18 Upvotes

Hey everyone! I am curious about what landscaping styles people are actually installing these days.

Personally, I feel like the word xeriscape has become so misconstrued since people often assume it just means rocks and cacti, while newer terms like Coloradoscape just do not quite roll off the tongue. Meanwhile, nurseries keep pushing words like WaterWise, climate-adapted, or true Colorado natives.

For those of you with low-water yards, I would love to know how you actually describe your landscape to neighbors. I am also curious what philosophy you chose to follow, such as true habitat-focused natives or a structured low-water garden, and why you prefer that approach over the others.

Just looking to see if there is any consensus on terminology.

Got them in a garden in the box; it's been in the ground a few weeks and has adequate water (same soil as the rest of my other two garden in the boxes, but all three plants are yellowing from the bottom up. Crowns are free of debris.

Large amounts of bugs?

12 Upvotes

Hello everyone, it seems like I am having a large infestation of tiny little flying bugs in my yard. They are all over my windows and I'm wondering if I should be worried or if this is just a vigorous year for bugs.

They look like little tiny flies? Potential midges maybe? Unsure.

Thanks for helping me out.

mixed advice on whether to cover or not 😅

8 Upvotes

Hi! I know there are already a few posts about tonight’s potential frost but they seemed more vegetable and tree related, so hopefully this is okay!

I planted the Pollinator Peak Garden in a Box a couple months ago (late August). Other than one bee balm, they all seem to be thriving (or at least surviving). This is my first attempt at gardening ever in my life so I want to make sure I’m doing things as correctly as possible.

I asked my mom (major green thumb but in the Midwest) and my good friend (also green thumb in the Midwest but with experience gardening here) and they gave me mixed advice. So I’m looking for more opinions 😬

Do I cover the plants tonight? With what? Bags or a sheet? The packet that came with the plants says to trim the bee balm to 6” in the late fall. Should I do that before tonight or will it mess something up trimming so close to a frost?

Thanks for any advice 💚

Sup Denver gardener fam! Hope you’ll accept a green mountain/ golden submission. Planted 90% of this garden as summer was winding down this year. It’s been such a fun journey looking at other posts here and finding things that would work well in the garden.

When my wife and I bought this house a few years ago the front yard had like three ornamental grasses planted that were all dead, it was atrocious. Since then I’ve done trial and error, so many fallen soldiers due to bunnies in my neighborhood. Did all this myself from research to planting and it’s been a joy of a project particularly this summer. Tried to source mostly through plant select but there are definitely some non natives and red headed step children I planted before learning more. Anyways, full list is below. I’d love feedback but if you’re mean to me I’ll rip all this up and throw it away so pls be sweet.

We’ve had hummingbirds in my front yard the past few years and that’s what inspired all this. This past summer we had a pair in the front yard and backyard, they loved the salvia along other things. Monarchs are showing up too, I got my monarch watch sign on proud display! Anyways, here’s the garden:

Late planting- advice on how to overwinter starts

6 Upvotes

ADVICE NEEDED: what is the best way to overwinter these babies?

Due to a 3+ week delay in receiving starts from High Country Gardens (grrr...), I am getting starts this week. Obviously its late seasonally to plant them. We got snow last night (6,500ft).

My choices are: 1) plant them in prepped bed and hope, 2) leave in pots and "plant" in soil overwinter outside to plant in final places in spring to protect tap roots in existing starter pots, 3) bring into garage in starter pots for overwinter (full sun, approx 50degrees all winter), 4) bring into house like houseplants.

Here are the species:
Gamma grass, Rice grass, Yucca, Sage, Red hot poker, Common Sotol (Dasylirion), Curry Plant (Helichrysum italicum)
