I hate that you cut all the canes off.
I grow roses from the un-rooted canes all the time... I just shove the pieces into the sand, water once and walk away.
I don't understand what all the pantry stuff has to do with growing roses...
Rather than a discussion of these weird baking ingredients, we actually need information about what kind of soil you are dealing with.
Sand? clay? gumbo? caliche?
Lot of different soil types in texas...
Maybe tell us what city you are near, and we could look this stuff up ourselves...
