And the last question of the night is .... dogwood tree. One appeared
here today. I killed the last one. What do they need to survive in Zone
5?
Hi Donna,

   Do you know if it's a cultivar, or just the straight species?  And I
   assume that you mean Cornus florida (the native flowering dogwood)?
   There are tons of different dogwood trees...

   If it is Cornus florida, you shouldn't have any problems growing them
   up by you.  The Morton Arboretum has full-grown specimens that have
   survived for decades.  They don't always bloom after a really cold
   winter, but the plants do OK.

   They need shade and significant moisture until their roots get
   established.  They prefer good drainage and a humus-rich soil, but
   will do OK in regular clay as long as they're not planted in a hole.
   Planting them on a slope is best, if possible.  They also like
   acidity, so you might need to treat the soil with sulphur.

   The real key to success is to not let the tree get stressed during
   the first few years.

   Good luck!

Chris
