Fast climbing evergreen plants

Hi, I was wondering if you could recommend a fast growing climbing plant that stays full all year long? I would like to train it up a narrow trellis against my 6’ cedar fence and eventually add a horizontal narrow trellis along the top of the fence to add height for privacy, Thank you! -Andrea

Strong smelling weed

We have a peculiar weed that starts like a flat rosette but by mid-summer branched up to several 12" central trunks with side limbs like small tree. It is kind of grayish green until it dries and turns reddish-brown in late summer. Has many, many little seeds on each branch but no leaves. The most remarkable thing is its very pungent odor. (It's not growing now, so don't have a photo to send). Can you give me a clue as to what it might be?

Apple trees in residential backyard

Hi. We bought a rental home and the previous owners have grown and taken care of three really beautiful and very fruit bearing trees. I think they have been groomed well prior to my ownership and they are shaped in a very umbrella like shape and very tall. This last year the apples all had small worms or maggots in them and we tossed 95%. Like to know what poison or services I should employ to get harvestable fruit from them this year. Currently there are new buds beginning to just now open on the branches . Thanks for any help

Lead Testing for Soil?

Hello, We are planning 2 raised garden beds in our backyard to grow veggies. Our house was built in approx 1948...would you recommend that we have our soil tested for Lead before proceeding? If so, how would I go about doing this in Tillamook County? We live in Nehalem. Thank you! -Ashley

Bird eggs

I believe there are leftover bird eggs, in a nest, built last fall. I have pics. Should I remove the eggs? I presume that they are non-viable(from last occupant). It appears that another bird is attempting to build a nest(add-on) to this previous structure. Will dead/left eggs interfere with future habitants or should I remove the left eggs?

Flea Beetles

I have gardened for two years in Newberg and each year the flea beetles arrive and do significant damage. I bought nemotodes last year and it didn't seem to help. I've since read that there are certain types of nemotodes for certain insects so maybe I purchased the wrong kind. Any suggestions? Thanks, Kirsten
