A couple of tree ID's
I made my first ID at GardenWeb today (deodar cedar), but Ron_B beat me to it. That's OK, I know I knew, they can't take that away from me.
I just got back from the mid Atlantic area (mainly Virginia) and ran across a couple of trees that I couldn't ID.

How far below ground should i cut oak tree stump?
Removing tree stumps. What a sad task, even sadder when you have to do it yourself!
A chainsaw is a totally inappropriate tool for doing what you are trying to do. That is why they use a stump grinder not a saw when a professional service does it.
Dawn Redwood demise
Greyneedle says it all: root failure.
I planted it last fall, it looked great, fine during winter, budding this spring, new needles, then suddenly in last 3 weeks, everything shriveled up and died! bark loose; needles brown, twigs hollow with no green- in a word, dead. how did i manage to kill this hardy tree?

Simple fuchsia tips
This is the kind of simple, direct, fail-safe advice we need more of:
Don't forget to dead head the old flowers (removing the seed pods too) as this will help with the continuity of flowers. You also need to feed the plant (half strength high potash feed (tomato feed) every other watering
‘Seeds of Success’ program chronicles native plants
The key is to make these seeds available. I can't tell you how many native seeds I'd like to get my hands on, but can't do so except perhaps in minute quantities from other enthusiasts. You folks in Medford: think about how you are going to distribute these. Collect enough material to allow some limited distribution.
A team of four college students led by a Medford botanist will canvass public lands in southwest Oregon this summer to collect native plant seeds.
Growing stuff found in your kitchen cupboards
What the heck is taro?
I grew small taro in a deep container last year. They are 0.99 a pound in supermarkets. Taro leaves are pretty but I haven't seen any flower. I brough the plants inside over winter. This year I repot the plants and found many new baby taro under the soil.
what natives have worked in containers for you?
I don't know, natives in containers sounds self-contradictory to me...

Cotton Farmer Races Against Clock to Plant Seed
This story is somewhat disjointed, but I find the tight timeline interesting:
"We did get beneficial rain, and now, well over 50% of our 3.7 million acres has been planted in the last six days."
That's about 2 million acres of seed. I can dream, can't I?
Cedar Rust Diseases of Ornamental Plants
Cool pictures. Apparently this disease causes only limited damage to the juniper.
Cedar apple rust: On junipers, tan to brownish round to kidney-shaped fungal galls are present in winter and early spring. With moist weather, gaudy bright orange masses of gelatinous spores develop from these galls, and galls swell to several times their original size. Spore masses are several inches in diameter, with a central core and radiating hornlike tendrils, and are highly visible during moist weather in mid-spring.
Topographic mediation of growth in high elevation foxtail pine (Pinus balfouriana Grev. et Balf.) forests in the Sierra Nevada, USA

Aim Climate variability is an important mediating agent of ecosystem dynamics in cold, semi-arid regions such as the mountains of western North America. Climatically sensitive tree-ring chronologies offer a means of assessing the impact of climate variability on tree growth across temporal scales of years to centuries and spatial scales of metres to subcontinents. Our goal was to bring practices from landscape ecology that highlight the impact of landscape heterogeneity on ecological pattern and processes into a dendroclimatic study that shows that the biophysical setting of target trees affects ring-width patterns. Location This study was conducted at two sites near alpine treeline in the Sequoia National Park, USA (36degree30' 00' N, 118degree30' 00' W). Methods We collected stand information and increment cores from foxtail pines (Pinus balfouriana Grev. et Balf.) for eight tree-ring chronologies in four extreme biophysical settings at two sites using proxies for soil moisture and radiation derived from a digital elevation model. Results Biophysical setting affected forest age-class structure, with wet and bright plots showing high recruitment after 1900 AD, but had no obvious effect on immature stem density (e.g. seedlings). Biophysical setting strongly affected ring-width patterns, with wet plots having higher correlation with instrumental temperature records while dry plots correlated better with instrumental precipitation records. Ring-width chronologies from the wet plots showed strong low-frequency variability (i.e. hundreds of years) while ring-width chronologies from the dry plots showed strong variability on multidecadal scales. Main conclusions There was a strong association between biophysical setting and age-class structure, and with ring-width patterns in foxtail pine. The mediation of ring widths by biophysical setting has the potential to further the understanding of the expression of synoptic-scale climate across rugged terrain. When combined with remotely sensed imagery, a priori GIS modelling of tree growth offers a viable means to devise first-order predictions of climatic impacts in subalpine forest dynamics and to develop flexible and powerful monitoring schemes.
