Unknown plant #752060

Asked May 25, 2021, 2:28 PM EDT

What is this plant. There are similar ones that grow a single stalk, same leaves, and this one that has "branches". Don't know if it has a flower because the deer have found in tasty and have eaten the middle stalk. I assume it is a weed because my neighbor has a similar plant but those leaves are much thinner.

insects in garden #752059

Asked May 25, 2021, 2:21 PM EDT

Something is eating my garden! I have planted beets, cucumbers, winter squash, zucchini, sunflowers, zinnias, and marigolds. As soon as they sprout to about 1/4" inch, something eats them overnight. Some of the plants have made it a little bigger, but again, something attacks the leaves and eventually kills the plant. I have put out slug bait, diatomaceous earth, and now even seven. I can't see any evidence of what bug/slug is getting them. Your expertise help is greatly appreciated.

asters and goutweed #752050

Asked May 25, 2021, 1:56 PM EDT

Hello. I've noticed that where various wild asters have sprung up from a ground cover, unlike where other plants are, that there is no goutweed also pushing its way through the openings in the (industrial) cover. Is goutweed put off by asters? with thanks.

Asked May 25, 2021, 12:27 PM EDT

All the leaves on two branches of a 20-year old Red tipped Photinia are wilted. The rest of the bush looks fine, as do the other red tipped photinia bushes in the hedge.  There is no leaf-spotting or curling on the wilted branches or elsewhere.

Red Currant Berries Don’t Ripen #752028

Asked May 25, 2021, 11:54 AM EDT

My red currant berries are not ripening. Instead, the berries stay green and then almost suddenly shrivel up without turning red at all. I’ve looked for disease and pest problems, but can’t see any obvious problems with the naked eye. The plant is otherwise very healthy. It is growing vigorously, leaves are a vibrant green, and the number of berries I got was surprising for a plant grown in partial shade in its second year (the bush was probably already 1 year old when I bought it from the nursery). Do you have any guess about what could be going on here with the berries that don’t ripen?

Trees dead or will they live #752027

Asked May 25, 2021, 11:51 AM EDT

I have 2 Japanese lilacs and 2 crab apple trees that have new branch growth. There are leaf buds throughout, but the buds are not bursting open or only a few leaves just popped out recently and are growing very slowly. I'm thinking it's winter / cold stress. Are my trees dying? Can I save them? Will they come back next year? Also I have a maple tree where 1/2 of the tree leafed out small and then the last few cold spells, those leaves seemed to stop growing. Other half of tree is doing just fine. Again is it savable? Should I worry about some disease throughout my trees?

Odd little worm found #752025

Asked May 25, 2021, 11:46 AM EDT

Hi, I live in west Eugene, and I found a tiny little yellow worm in a tree in my front yard today. Never seen anything quite like it before. I've attached a couple of pictures that I took of it. It's very thin, maybe 1mm in width, and when fully extended perhaps 3 to 4 cm in length. Any idea what it could be? Should it be destroyed or would you like me to turn it in?

Wisteria frutescens not producing leaves or flowers #752023

Asked May 25, 2021, 11:35 AM EDT

I’ve had this vine for a number of years. In the past it’s produced leaves and flowers, though the latter have not abundant. This year it developed little buds, but then no leaves or flowers. I think a late frost caused this. However, there are a couple of shoots coming from the ground near it which are producing leaves just fine. My question is “Is this vine likely to produce leaves and flowers next year or is it mostly dead?” Thanks for your consultation.

Can you identify this weed? #752010

Asked May 25, 2021, 10:40 AM EDT

This spring this weed has been growing in our Apple Valley yard, mostly in rocks around the deck, but also in the lawn. I can't find it in your listings, but on Google, it looks like "Veronica" speedwell. It has little blue flowers (not purple like creeping charlie) and lots of little spiky leaves on the tips. I have been losing the battle trying to pull all the chickweed in our grass, now this! We've also had more moss the last couple of years than ever in our 23 years here-- changing climate??

Crown rust fungus #752008

Asked May 25, 2021, 10:36 AM EDT

I have a fine line buckthorn. I believe it has crown rust. All the info I find says this is a fungus that primarily infects commercial crops (oats, barley, etc.). I can't find how to treat it. Everything I read says use what you use on oats, but doesn't say what that would be. Garden centers seem to be confusing crown rust with rust, but it appears to me they are different things. I am confused and don't know where to turn or what to do about this issue. Help!

Poorly draining soil #752003

Asked May 25, 2021, 10:16 AM EDT

The soil in my garden seems to drain very poorly. After a good slow soak with a handheld nozzle or a sprinkler, 10-30 minutes, the water starts to pool up yet the water only reaches about one to two inches deep. Below that it is bone dry. I’ve attached a photo but I’m not sure it tells you much. The soil doesn’t feel particularly clayey nor sandy. Somewhat grainy. What can I do to improve the drain ability of my garden soil? Thanks.

Raised Bed - lining and stakes #751998

Asked May 25, 2021, 10:12 AM EDT

Hello, 1. I was wondering if there is such a thing as too much lining for a raised bed? I got landscape fabric to line the bottom and edges of of the wood barrier which is just sitting on top of the ground. I put down 4/5 layers of fabric. Is that too much and might it negatively impact drainage? I did this thinking it might be better to put multiple layers to lessen the likelihood of passage of plant diseases from the ground to the plants that will be planted in the bed, however, I'm guessing if water can pass through so can diseases anyways, and I got stuff from the ground on both sides of the fabric anyways so any effort at separation for disease purposes may be moot? I also put an extra layer to try to keep soil from seeping out the sides of the bed since the border is just sitting on top of the ground and the ground is not entirely even. I think this is the fabric I used: https://www.homedepot.com/p/Vigoro-40-in-x-36-ft-PLA-Natural-Weed-Block-Landscape-Fabric-NMV4036BPLA/310978002#product-overview 2. I cut some holes in the fabric and some hammered some metal stakes into the ground within the raised bed area to hold the fabric in place. The ground below is pretty tough and the stakes were long so in hammering metal flakes came off the stakes. I was wondering if I should have any concern about letting those flakes sit there, or using metal stakes in general. Is there any risk of somehow contaminating the bed soil? I'm not sure but the stakes might be made of galvanized steel?
