What is eating my Sunflowers?

We're from Selbyville and we had a pest that ate 60 something Sunflower plants overnight, but left the vein in the plant (it only ate the green leaves). It left all of the other plants in the garden! We looked on the plant but there were no visible bugs. Do you have any idea what could have done this?

Browning leaves on hydrangeas

We planted 3 Endless Summer Hydrangeas on June 15. They are watered with drip irrigation. They are about 2 feet tall.

Last week when the temperatures got into the high 90's we started to notice browning leaves. Some of them continue to brown, and we've noticed black areas on the leaves before they turn brown. See attached.

Any suggestions on what the problem might be and how it might be fixed?

Pruning a Young Japanese Flowering Cherry Kwanzan Tree

Dear Tree Expert,
Our tree is about 2-3 years old. Not sure how old when purchased, but was planted in Spring 2011. It has never been pruned. Using my textbook from HORT 100, I have pruned 4-5 branches from the tree. One was the lowest sitting branch; the rest were competing branches. I read that for every 10' of tree height, scaffold branches should be spaced 6" apart. The tree is about 10' tall. However, it seems like the tree is too young to space scaffold branches 6" apart. If I were to do that, I wouldn't have many branches left. I've attached pictures to give an idea of the problem. In the middle of the tree, there is a cluster of branches. These are not co-dominant trunks. There is a main trunk that grows beyond this cluster. In fact, the trunk split into two branches - so I DID have a co-dominant trunk further up - but I removed one this year. What should I do about the cluster of branches in the middle of the tree? Should I wait until the tree matures another 1-2 years? Even so, how should I many branches should I remove?

Pollination of Female Hardy Kiwi

We have a healthy mature female Hardy Kiwi and plan to purchase a male this Fall in order to get fruit; but understand it could take up to 3 years for the male to mature to pollinate our female tree. I have been told there might be a place with the Oregon State Extension to get some male pollination for next Spring: Actinidia arguta or Actinidia deliciosa. Can you please help me locate a source? Thank you, Larry Burgess ( 503-695-3525.

Schip laurel problems

Hello! I have several 5 ft. Schip Laurel. All flowered in the spring and have produced berries, but their leaves are now yellowing and dropping. One plant has lost about 80% of it's leaves, yet I see new bud growth on branches. They've been established 1 1/2 years and I have not watered them much during all the rain we've had. When it doesn't rain for several days I will water them when I turn on the lawn irrigation system. No pests are evident. Do you have any ideas or suggestions? Thanks for any advice you can provide.

White coneflower problems...

I have white coneflowers that have started out beautifully but now I see very small insects within the cones. Some of the flowers don't fully develop and and the petals have small brown spots or markings on them. Part of one of my plants is actually just dying and I can't figure out why...could it be thrips? These are only second season plants having just installed this new raised garden last year...any suggestions? I enjoy attracting the bees and hummingbirds to this bed so I want to be careful about the use of insecticides. Thanx

Fungus gnats hovering around a person's head.

I had two houseplants infested with fungus gnats. After putting all plants outside, there were about 50 of these hanging around the ceilings. I vacuumed them up, put two samples on a microscope and confirmed they are fungus gnats (from an online diagram).

The problem is that a few of these are hovering around my son's head and driving him crazy. We've tried lice treatment to no avail. We can call an exterminator, but I don't see many of the gnats around, and I don't know that they can help with my son's issue. Can you help or refer me?

Do you know what these moths are (see attached picture) and if they are harmful to my tree? They have been sitting on a maple tree in my front yard all morning, moving slowly around the trunk. I have never seen any like this before. They are about 5 inches across. They seem to be mating and perhaps laying eggs (though I haven't seen any).

Protecting Elderberry fruit

Wondering if you have any suggestions regarding protecting elderberry fruit. We have 4 varieties in our backyard. My wife uses the blooms to make "saft" a concentrate used to make flavored drinks in Sweden. We also have a lot of berries that are just starting to ripen. In the past I've used black netting to protect them from birds, but it doesn't do much good, occasionally traps a chipmunk, and pulls a lot of the berries off when you remove it. So I've thought about wrapping each berry cluster with something, but can't figure out what to use that would be economical. I've heard that the footies that are used at women's shoe stores can be used to protect fruit in the home orchard, but that wouldn't work with elderberry clusters. Do you think they need to be exposed to sunlight? Would a paper or plastic bag be bad? (I assume so). Only idea I can come up with is tearing up a lightweight sheet and wrapping the clusters.
