Perrenials over the Winter

Hi - at the end of the season I bought a few perennials (at Fred Meyer) I did not get planted before the freezing weather. I live in Oregon City. Is there a way I can keep them going over the winter and plant when there's a thaw? They are a cape fuschsia (phygelius), a cardinal flower (lobelia speciosa), and an ornamental oregeno (origanum rotundifolium). I have been keeping them close to the house and watered. Thanks!

I have a number of Clematis in my yard and they are all the type that bloom on new growth. Two of them are on the south side of my white house and I do not know when it is safe to prune them back. Supposedly I should wait till March but last year one of them had buds by then and after pruning back, it did not really bloom much. I would like to prune much earlier but do not want to encourage new growth before we have very cold weather. Right now most of the leaves are brown but not all and it is very thick and lush. Any suggestions?

Would spraying oil on citrus trees help before a frost?

In Galveston County we expect a light freeze in 4 or 5 days.
Will it do any good to spray now with neem or agricultural oil at this time?
By the way the citrus presentation by Dr. Monte Nesbitt was very impressive with excellent detail information.

How damaging will it be to trim oak tree roots to level sidewalk?

I will be doing some sidewalk leveling where mature oaks have pushed up concrete to an unsafe point. Will have to trim some of the main roots - maybe 2-3 inches in parts. Will this hurt or kill the tree? Any preventative measures? Thanks.

We reseeded our lawn early in September and it took great. Because the voles are still actively tunneling throughout the yard my husband wants to get a lawn roller to crush these tunnels. It has been mowed a couple times and we have run the lawn tractor over it to blow leaves. It still is a nice green color. My concern is will we damage the new grass if we roll it throughout the winter?

Is this Rose Rosette?

Attached is a photo of one of 4 roses I have that are growing strangely. At first I thought it might be herbicide drift but it seems to fit the Rosette description I found on the internet and I've never seen it before. Is there anything I can do to save the plants or should I rip the infected plants out immediately before the other 26 plants get infected? Thanks, Rick Holcomb

Hi there, I read HGIC Center Director Jon's newsletter about "dumping bags of my neighbor’s leaves around a fig tree" and I just did the same thing last Sunday! :) Not only one fig tree but a few, as well as some other young fruit trees such as peaches, cherries, jujubes and a pomegranate tree. For some I used the net barrier to protect the deers from eating the barks/leaves to hold the leaves together, for others I used some leaf paper bags to hold the leaves around the tree bases. But I am not quite sure whether this is a good reliable way to winterize my young fruit trees. Before I used some brown papers wrapping around the tree bases then using some plastic wrapping around the outside, and the fig trees have been doing well that way. I want to confirm my current protection is enough from you experts before it's too late for the season, thinking we may have a very cold winter. Thank you! Marrianna

Growth of new grass, then quick die off

I live on a lake, my soil is sandy. I have several larger areas where grass does not want to grow. I prep the soil, even removing the first few inches of existing soil, then add fresh top soil as well as some miracle grow. I water regularly and have don't cut too early with new growth. When I plant seed I get a good initial growth, but then just as quickly, the new growth becomes patchy, with brown grass and then complete die off shortly afterwards. I have planted grass many times with much success, however, not here in Michigan on a lake. Please help
