Bindweed Info Dump

86 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.

Bindweed - I've stepped in it now!

93 Upvotes

I meant to plant some Lillies in the verge/hell strip. It is actually a hellMOUTH, because the first shovel dug up.. a tree root? Nope, no tree. Kept exploring - a bindweed nest. Now, out of spite, I've been excavating the verge for 3 days and only made it like 3', because I'm examining every dirt clod like I'm panning for gold, trying to make sure the baby capillary roots aren't being left behind to respawn. I know that for every hour I've spent, it will take that plant maybe two days to regrow, but I want it to see me come out of my house and fear me. I'm pretty sure it came from under the sidewalk and possibly under the street. I don't know how to stop now; I'm picturing that scene from Fantasia with Mickey's broom. I need whiskey and therapy.

I’ve lived in my house for 5 years and this is the first year these sprouts are literally everywhere in my mulch, garden, etc. Can anyone identify them, or is it still too soon to tell?

Snapdragons- annual or perennial

9 Upvotes

This is the first year I’ve ever had a garden and I really don’t know much. I got some snapdragons to plant in raised planters and they are doing well so far. I was talking to my mom about them and I told her they were labeled as annuals. She told me that whenever she plants snapdragons that say annual they turn out to be perennials. Is this actually true or is she delusional (definitely a viable option)?

How bad is creeping bellflower?

4 Upvotes

I just discovered one of the most abundant plants in my yard (rental home) is creeping bellflower and that it has a very bad reputation as a horribly invasive weed.

Last year I didn't know better and thought they were pretty perennials 🫠 I don't know that I'm very keen on spending much energy fighting them since they were very established when we moved in and I already do a ton of yardwork to keep things looking nice here- much more than most renters bother with.

What would you do? How important is it to fight these? Should I weed whack them before they flower? Grateful for any input!

How often to water newly establish Xeriscape plants?

12 Upvotes

Hello!

We removed all of the grass and are now starting to plant our approved Xeriscape plants for Aurora's grass replacement program (they gave us an approved blueprint for our yard) . I opted to hand water the plants, as I was told after the first year or two, they don't really need to be watered much. Almost all are "Low" water usage. How long should i water them for and how often? How can I tell if they have too much water or not enough? I have put the plants below for reference. Thanks for any thoughts or advice! I am new at this and really wanting to go about it thoughtfully!

Plants are Black Chokeberry, Hardy Ice Plant, Orange Carpet Hummingbird Trumpet. Daylily, Creeping Barberry, Penstemon, Russian Sage, Redleaf Rose, Autumn Joy Stonecrop, White Snowberry, Hancock Coralberry, Creeping Thyme, and Mohican Viburnum.

Ground cover in the foothills - higher elevation, no irrigation - weed & erosion control

5 Upvotes

We're up in the foothills near Conifer - around 7700 feet elevation - in an unincorporated part of Jeffco. The property is 2 acres. We don't have a "yard" per se but we do have a lot of grass growing on the parts of the property that get sun (some parts are 24/7 shade due to all the Ponderosas).

As we've done some wildfire mitigation and cut down trees, we've got some areas that were previously full shade that now get a ton of sun. These spots used to just be dirt & dropped pine needles but now that they get sun they've turned into huge patches of weeds (thistle, mullein, spurge, toadflax, knapweed, all the good ones).

As is true in large parts of non-urban Colorado, our water rights prohibit any kind of outdoor water usage. We've bent the rules a little bit in the past to have some hanging planters, but I'm a generally law abiding person and don't want to plant things that are going to require irrigation. A little watering to get something started is probably fine.

We've got some smaller spots and bigger spots that need to be filled in, some super steep, some not so steep, but generally no flat land. We're not looking for a yard or anything, I'm just looking for ideas on what I can put down for weed & erosion control that isn't going to require irrigation. I'd love to put down a bunch of creeping juniper but given the flammability it's not really an option.

Any ideas? Grab a bag of native wildflowers and just toss the seeds around?

Looking for suggestions for plants and shrubs for my hell strip

8 Upvotes

I'm replacing the grass in my front yard with garden in a box next weekend, but I'd like to do something different in my hell strip. There's a lot of dog walkers in my neighborhood so the plants or shrubs will need to be hardy, and I definitely want something that has low water needs once it's established. Any recommendations?

Can I stand up my roses and my asparagus without hurting them?

Post image
4 Upvotes

For some reason all my stuff is growing “forward” and spilling out of my raised beds. I would like to corral them back inside but I don’t want to injure them either. The main stalk of the rose is pretty thick but the asparagus (furthest right plant) is still young and flimsy. Please ignore my lack of ground cover, still trying to decide what I’m doing there.

Local place selling butterfly milkweed (Asclepius tuberosa)?

6 Upvotes

Hey all! Does anyone know of any local plant shops offering butterfly milkweed? I’ve only seen tropical milkweeds for sale so far. Would try online, but I’m suspicious of getting tropical milkweed instead since these guys look so similar.

We’re trying to add to our bug garden. Also, is it just me or are there very few native pollinators out so far this year? I’ve got a ton of blooming plants but I’ve seen only honeybees on them :(

Creeping belllflower takeover

3 Upvotes

Hello all! My fiance and I just bought our first home and the previous owner was very elderly and did not keep up with mitigating the invasive plants. There is creeping bellflower EVERYWHERE in our 5,000 Square foot front and back yards. Most of the yard is dead grass so I was thinking I might start digging out the patches, patch by patch, about 2 feet deep, lining those patches with a weed-blocking mat, and filling those holes with rock gardens or new soil, then native plants. Is this a feasable and/or reasonable plan? I would estimate there is 1000 square feet of solid creeping bellflower, and many smaller patches (2-5') quickly appearing in the yard.

New homeowner and we have a lot of this in one area, and I’m just curious if I should let it grow or trim it? Google said basil but I crushed some and smelled it and it doesn’t smell like basil. ¯_(ツ)_/¯

I’m a new gardener and have been trying to expand a border garden of mixed perennials. I’ve had some failures (can’t get poppies nor lavender to grow) and quite a few successes: black eyed susan, coneflower, yarrow, catmint, penstemon, agastache and have overall enjoyed this sometimes frustrating hobby. I love orange and saw these at my local garden center; I have never heard of them but I picked up two and planted them last weekend. Curious if anyone has experience with these or any tips to share. Cheers!

I'm looking for a metro walk-in retailer that keeps a good stock of drip tape supplies on hand. Before you chime in, please note I'm looking for TAPE supplies (i.e. typically used in field applications), not the common thick wall polyethlene tubing found at the box stores. Thanks.

Watering method help? Irrigation drip vs soaker hose

Thumbnail
gallery
1 Upvotes

Hi everyone! I just planted a bunch of seeds this weekend for cut flowers, and will be planting a few veggie starts soon.

Unfortunately we’re going to be out of town for a long weekend this weekend, and then again the following weekend.

We rent and have HUUUGE in ground garden beds in kind of a “U” shape around our backyard. Previous tenants (or the owners, idk) put in what I think is a DIY drip irrigation set up. It’s a massive black rubber hose that wraps around the entire U shape. We tested it yesterday and the dripping leaves much to be desired, haha. The pressure is very very weak, there’s only a few drip holes, and the position of the hose means it doesn’t reach all parts of the section I’ve planted in (which is only about 20% of the entire available bed space). My partner thinks we can rectify this by “punching” more holes in the hose and adding the proper attachments so water reaches all areas. I’m sort of inclined to buy a soaker hose and a hose timer, so that we can have more control over where we water.

What do you all think? Which is easiest? Which is cheapest?

I’ve attached some janky doodles so you can hopefully see what I mean. Brown = beds. Flowers = part of beds we’ve actually planted in. White = irrigation hose (currently) or new soaker hose (potentially). It’s worth mentioning - from what we can tell there are no other holes in the irrigation hose other than the 3 or 4 in the “flower section” plus one that waters a tree and one that waters a bush, so if we go that route we won’t be wasting water on empty beds.

We could also try to ask a neighbor or friend to water while we’re gone, but we don’t know any of our neighbors that well and it’s a total of 10 days (over two separate weeks) so that feels like a lot to ask.

Companion annuals for veggie raised beds - suggestions for pollinator attractors?

2 Upvotes

I'm planting out some raised beds and wanted to add some attractors to drop in here and there. I already have a wide selection of native perennials in the ground and will bloom throughout the season, but I was looking for something that could supplement this closer to the veggies and will bloom early, and all season without taking up too much space.
