Lead on Tomatillos?
Attempting to crowdsource any thoughts on where I might scavenge a couple of tomatillos. Anyone have starters they’ll sell? Any stores still peddling the last few sad specimens? I fell victim to a pill bug infestation (never in my life have they been an issue here! Here’s to the climate apocalypse… 🫠) and lost some.
I know we’re past our prime on these, but tomatillos are amongst my favorites. Sadly, these perished from seeds I’d saved from last year.
I just bought some diatomaceous earth and am crossing my fingers….
Hollyhocks and japanese beetles. EVERY YEAR
I love my hollyhocks, but every year just as they start going full bloom, the Japanese beetles find them. I end up having to cut them all down or risk that the beetles will get a hold of everything else in my garden.
They are great at attracting bees and pollinators in general. They thrive on neglect, but they also seem to attract so many of these little fuggers that i have to go scorched earth.
Anyone have a solution so i dont have to?
Privacy plants for fence
Prefacing this with I am a terrible gardener so please give suggestions that even a dummy like me can execute.
I have two dogs that LOVE to run up and down the fence barking at neighbors anytime they detect movement on the other side. I need some sort of plant that blocks their view to the other side. I don't much care if it's a grass, a shrub, or something else but I would prefer one that is not attractive to rabbits or stinging insects because my dog can and will catch them. Full-to-partial sun. Willing to wait on planting it if this is a bad season.
Plant shrubs now, or wait until fall?
Now that a lot of nurseries are beginning to discount their stock, I (perhaps unwisely) purchased Amelanchier alnifolia 'Obelisk' (Standing Ovation serviceberry), Ribes aureum (golden currant), and Arctostaphylos x coloradensis (mock bearberry manzanita).
Should I plant them now, or keep them in the nursery pots and plant them in the fall? I feel like I'll be babying them in this heat either way, but what is my best chance for success? They'll be on the northwest side of my house, so they will receive a lot of morning shade (and possibly even some in the early afternoon).

Where to find broken colorful tiles?
Totally revamping my garden and would like to find cheap/free broken tiles to line my path and raised beds. Thanks!!
Apple Tree Suddenly wilting?
Left town for a couple days and our apple tree looks quite sad. All leaves have curled and seem dry. We’ve several other apples in other places that all appear fine. What might have caused this?
A leafcutter bee was building a nest in my yard yesterday.
Two years ago this yard was a mix of concrete and river rock over weed tarp. I ripped it all out with the goal of providing bee (and other insect) habitat in my little tiny slice of denver.
I was so happy to see this leafcutter bee building a nest in the ground yesterday. It's made all of the work worth it.
Yesterday I also saw Thread Waisted Wasps, Club-Horned Cuckoo Wasps, a few types of Metallic Green Bees, Longhorn Bees, Red Sutured Longhorn Beetles, and so many small bees I haven't identified yet.
Bees be bombing bee balm
Although mine are super leggy, I love these plants. Attracting all kinds of pollinators. (Including some outright enormous and evil looking wasps).
My catmint “Cat’s Pajamas” - in my opinion, the best cat mint cultivar but I’ll happily be proven wrong if you share pics of yours
Periwinkle…to keep or not to keep?
I replaced my Kentucky bluegrass lawn with pollinator friendly natives/perennials last fall and seeded quite a few annuals this spring. I noticed this periwinkle growing and acting a bit uncomfortably like bindweed. Will this crowd out all the other species I’ve planted or will it behave itself or even keep out the bad weeds? Should I leave it to spread, or get rid of it with haste? Many thanks!
Fall Plant Dates Garden Planner Info
Edit - better photo in comments
Found this in my stuff. I set the first frost date to Oct 5th, since the average is Oct 3-7.
Coming up soon on the last plant dates for some of these. I am bulking up for freezing and canning.
Tree ID Help?
Struggling to ID the two trees in the backyard of the home I bought last year. My neighbor, who has lived here for several decades and knew the previous owner, has claimed it’s an “apple”.
I’m a landscape architect with 10 years of experience. While I’m embarrassed by my inability to ID this tree (granted our profession does not generally teach much about fruit trees in school and I work on civic projects almost exclusively (i.e. NEVER residential)), but I doubt this tree is an apple tree, since we bought it in February of 2025, it has never produced fruit.
Admittedly I’ve asked AI, but it doesn’t really seem to have the nuance required here. My best guess is a European Plum, but I’m still unsure because as I mentioned, it has not produced any fruit since we moved in.
Any idea what these might be? They’re currently about 15’ tall. For whatever it’s worth, the guy that used to live here seems to have bought everything (irrigation equipment, pavers, plants, edging, mulch etc) from big box stores like Lowe’s and HD, so it wouldn’t surprise me at all if these were random fruit trees that a big box would sell.
Too late to plant jalapeños?
I would get a plant, not seeds, but am I too late? I have a raised bed with full sun most of the day.
Doggtuff planting
We are tearing out half our back lawn this coming week to prep for planting dogtuff in 3 weeks time.
It’s a good spot that will get good sun, so no worries there, and we’re doing half now/half later so the dog still has a place to play and nap and frolic.
This was the only times we could the work due to commitments, but apart from the timing if anyone has any advice we would love to hear it!!
What are your perennials that always come back after winter?
Mine are yarrow and valerian in the sun and hosta in the shade. Everything else is just iffy.
