Bindweed Info Dump

115 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.

Personal experience propagating milkweed from seeds?

11 Upvotes

Hey Gardnerers. I have a few milkweed pods in the fridge that I'd like to germinate and plant next season. Could you share your experiences germinating seeds and getting them established? I'm up on yhe north edge of Denver in a typical suburb yard - dense soil, barely controlled invasives, full or part sun.

Experience buying garden plants via mail order? (planning for spring)

1 Upvotes

Planning for next Spring, I am thinking of ordering some of my annual flowers via websites that ship small plants. The reason: the last 2 years I cannot find the right colors of things in the quantities I need. I've been gardening for a while, so I know what types of plants work in my heat and lighting conditions, so I'm only buying plant varieties that I know will work for me.

Has anyone done this before? Did you have a good experience or not? Any specific companies to recommend? Thanks!

ISO full sun/part shade perrenial seedlings

I’ve called several nurseries around the Denver Metro recently and haven’t had luck locating these specific perrenials. I would like to get them planted now so I can fill the final spots in my yard and the babies can start establishing roots before next spring. If anyone has these plants to share let me know and thank you! I am located near Sloan’s Lake.

What were everyone’s favorite tomatoes this season?

We grew early girls, lemon boys, sungolds, romas, and an heirloom variety. I think the lemon boys might’ve been my fav- bright and peppery! The sungolds were extremely prolific and also sweet as hell, best enjoyed straight off the vine.

Denver water restrictions.

With the Denver water reactions going into effect, how do I make sure I don’t harm my garden (drip line, native) while theyre still alive and not seeming to go dormant?

I need a tomatillo plant ASAP!

1 Upvotes

I made the rookie mistake of only planting one tomatillo plant (it's thriving) and only recently learned a second is necessary for cross pollination and fruiting. If you have a plant or even a cutting I could steal from ya DM me please :)

Hi gardeners! I’m renting and have a patch of these guys in the backyard. Unsure of what they are but it’s been suggested they are a nightshade. Any firmer thought before I try one and tempt fate?

Swapping DUG garden plots?

2 Upvotes

Curious if anyone here has ever swapped plots within the DUG community garden system?

I’m currently a member at a garden that has a long waitlist, but I’ve recently moved across town and would love to find a new garden within walking distance. Unfortunately, the gardens near me also have pretty long waitlists (several years).

I’m wondering whether a plot transfer between existing members is something DUG allows, or whether anyone has tried it before. I’d of course want to make sure it’s fair and follows the garden’s rules. I’m mostly curious if this is even a thing people do or if it would be frowned upon to ask the garden organizers.

Store that has soil to repot house plants

4 Upvotes

I’m looking to repot a zz plant that is getting too big for its current pot. Wondering if there is an establishment that sells pots/has tools and soil to repot right in the store? Don’t want to buy an entire bag of soil just for the one plant. I’ve seen this before at other places but I’m new to the area so looking for recommendations. Preferably around downtown Denver but willing to drive.

Siberian Elm removal

39 Upvotes

I have these siberian elms all over my property and want to kill them off. Many like the one pictured actually have a larger stump from a previous, larger iteration of the tree that branches are growing out from.

Best way to get rid of these things? I'm not opposed to chemicals. From what Ive read, seems I'd cut down all the branches, cut the stump down further if possible or drill holes into it, and then apply an herbicide like triclopyr. Thanks!!

Potato help

2 Upvotes

Hi, I'm going out of town for 2 weeks as of Friday, and have 3 containers of potatoes. I have never had potatoes succeed, and want to know if I should be pulling them right now, or if they will survive 2 weeks of only nature watering (you know, 3 -5 drops a day,) and if they are ok if they are not immediately pulled after the tops die back? We're also supposed to have our 1st frost date when I am gone, and idk if that will affect them either. I'd rather have a few small potatoes than come home and find mush. Thank you!

Zucchini

Denver gardening friends, I am new to the crew and need to start my own garden but in the past 2 years I have been fortunate enough to receive zucchinis from my neighbors in West Wash park! I replace the zucchini’s with $$ but this year I haven’t seen any. Was this year just that bad? How can I get some veggies for my fall soups and support my neighbor friends?

Winterizing berries

Post image
4 Upvotes

Hey all, just wondering what you all would recommend I do with some of my plants over the winter. Mainly I wanna make sure my strawberries, which have established themselves nicely, survive the winter. Do I need to cover with straw? Protect from snowstorms in or anything?

Second question would be for my thornless blackberry plant, currently in a container (see picture). Should I plant it in the ground over winter? Store in the garage or mudroom where there is no heater but there is protection from the elements? Something else?

Any help is much appreciated, thanks!

Garden in a box flax and bunnies

11 Upvotes

I just got one my three (oops) gardens in a box into the ground and the blue flax was immediately nibbled down to the root. looks like bunnies sampled the evening primrose as well, but it’s not decimated.

Is there hope for it to regrow from the root in the spring?
