Aphids #765438

Asked August 03, 2021, 10:21 AM EDT

We have a healthy infestation of aphids on our nasturtiums. We understand that , to a point, this is good because the aphids will gather on these plants and not on our more desirable plants like our food crops. What is the risk the aphids will move to the plants where we don’t want them? Would it be advisable to thin or completely remove the nasturtiums , o does that just remove the trap crop and risk an invasion of th aphids onto our desires le plants. Thanks.

Diseased boxwoods #763180

Asked July 22, 2021, 9:15 AM EDT

Hi, Growing in my backyard are 40 year old boxwoods that are planted in two long rows. Over the last 4 to 5 years, an individual plant among healthy plants will show the following sequence of disease symptoms: one branch will stop growing, its leaves will turn bronze, and then the leaves will fall off. Then another branch or two will repeat the same sequence, and finally, all the remaining branches repeat the sequence until the plant is dead (see plant pic for disease progression). There are no obvious black cankers like those associated with boxwood blight, but I do see some white speckles on a dying eaves and stems (see closeup pic). It looks like I'll eventually lose all of the boxwoods unless I can find an effective treatment. Please help me! Can you tell me what the problem is, and how do I treat it? Incidentally, I work on the College Park campus so that I could bring some samples to the Plant Sciences Building, if you are still located there. I am really grateful for any assistance that you can provide me. Gratefully, Todd Cooke

Gerbera Daisy flowers grayish, not opening fully #762918

Asked July 20, 2021, 9:35 PM EDT

My Gerbera daisy in a container has great looking foliage, but the flowers are not opening fully and the edges of the petals look gray. I keep reading about mildews on the leaves and crown but nothing about the flowers. The leaves look great and the crown is not rotting. I have it in average soil. The pot it came in was mostly water-wicking sphagnum and peat. I let it dry out on the top before watering again. The flowers are not droopy, just don't open fully. Any ideas? Thank you.

Can I keep a branch of a fallen tree that is blooming now alive and turn it into a new tree? #746472

Asked April 26, 2021, 9:22 PM EDT

We had a HUGE tree in our front yard. I think it was an American basswood. It had two main trunks, and grew close to our creek. The creek bed eroded. A big wind came and the tree split in half and one side fell one way and the other fell the other way. Now we have a giant tree down in our yard. Long long story short, the part not covering the driveway lay there through the winter, and is now being chopped up and carried away. However, the many branches that are still spread through the yard are blooming!. Even on big branches that have been cut off from the main trunk, smaller branches are now sprouting leaves. Is it possible to take some of these sprouting, blooming branches and make them grow into new trees????? I want to save this beautiful tree and make branches of it grow into trees in our yard.

Apricot Trees #741289

Asked March 28, 2021, 9:03 PM EDT

Many years back, I put two apricot trees in my back yard. A few years ago, one got shaded out by neighboring trees and died. I have no idea what apricot I need to plant since I originaly planted a Sunglow and a Moonglow. I do not know which of the two survived. I know I need two separate species. Do you have any suggestions? Regards, Jeffrey W Johnston

Just wondering what type of tree this is. We had a couple when I was growing up and I used to think that they look very bare but I kind of like the look now. It brings back good memories. Thank you in advance. ☺

History of Horse 4H in Oregon #639104

Asked May 27, 2020, 1:26 AM EDT

Hi! I participated in the Clackamas County Horse 4H program from 2007-2016 and I am now a senior at CSU studying equine science. I am taking a class about 4H youth and extension and I have a project where I have to dive into the history of how horse 4H started in Oregon. I haven't been able to find much online, and I was wondering if anyone knew much about the history of how horse 4H began, who helped create it, and just any stories on how the evolution of how horse 4H began in Oregon. Thanks! -Alli

Marshall strawberries not developing #638978

Asked May 22, 2020, 1:56 PM EDT

12 marshall strawberry plants were ordered from Raintree Nursery and arrived in the fall of 2019. 4 plants were put in a new raised bed, 8 were potted in 2 gal containers. Today the foliage is looking great but the berries are not developing. Plants grew stems with blossoms starting 3-4 weeks ago, but after a small "button" starts there is no further growth, and the stems seem to lose their strength and wilt. The plants are in 3 different locations and all have the same problem. I picked and planted these berries in the 1950-1960 era and do not remember this situation. Berries rotting due to wet spring is common, but we"re not getting berries. A call to Raintree Nursey was no help at all.
