If you want to drill into the chimney I am sure there are sources of info more reliable than a landscaping forum, so be sure to check with someone - masonry suppliers and similar locally should be able to tell you how this is best done, or do a little googling around the internet. Or surely there are books on the subject; maybe some books on growing climbers would address this. I am not sure you need to go in four inches, and I wonder whether you should be drilling on the face of the chimney or on the sides of it - seems to me the sides would provide better holding dynamics. You don't want to demand too much of the corner brick, but perhaps a brick right in the side, one that is mortared in all around. The wires do not have to run in the shape you want the rose to grow in. They need to be positioned and secure so that you can attach the rose in that shape. I wold just run sequential lengths across the chimney (attached at the sides, again), each attached separately, so that if one gives out, the others might hold. Not that you want to ask too much of the corner brick, but maybe the second or third one in. The product linked below also looks pretty good for the holding system. Another one from the same supplier but a little flimsier (no drilling required) is here: http://www.leevalley.com/garden/page.aspx?c=1&p=47472&cat=2,33286&ap=1 Here is a link that might be useful: Trellis kit

Here are mine in a greenhouse one year after planting in 10 gal pots. The two wire trellis is already full. Right now there are 11 pots on 32 linear ft of trellis but that will be reduced to 4-8 after I see how vigorous they are and which varieties I like best. The plants grew at least 20ft the first year. Haven't decided yet if the foliage will stay on top of the wires or hang down each side. In the past two in-ground vines were on this trellis. They hung down each side but were overly vigorous hence the pots to give me better control of water and vigor. I'll get sweeter and more flavorful fruit by shorting water some.

Not a Ponderosa, they do not have winged petioles. And, Ponderosa fruit is not evenly crinolated, like this fruit is. I agree with Gyr in your previous thread, it does look like Merdeka. http://citruspages.free.fr/limes.html#longispina I would ask the Science/Botany department of that campus to see if you can find out who planted the tree. They may be able to correctly ID the tree for you. I would also suggest you post photos of the fruits and very, very clear photos of several leaves over on the Citrus Grower's Forum. Patty S.

I got my sister hooked on the trains last time it was open. I usually like playing the first one (the little one). It doesn't have the bells and whistle but I zoom in and it doesn't have the delay like the others.
