Bougainvillea goes to Town

 Over the past three summers in Kansas I've planted these Texas purchased bougainvilleas in the garden. Two are five years old, one is red and the other orange flowered. Another was given to me by my mother last fall. When I lived in San Antonio they were some of my favorite container plants but were somewhat persnickety when it comes to producing blooms. I researched many different methods to produce blooms and discovered a few rules of thumbs for my particular growing zone in Kansas. They bloom more often when they are pot bound. Many landscape contractors will transplant the growing pot into the new pot and slit the growing pot down the sides to allow some root escape. They are heavy feeders , but  heavy nitrogen amounts will create more foliage than blooms (kinda like tomatoes). They seem to do very well in my compost enriched soil with no additional feeding. When moved from one growing condition to another they often take 3-4 weeks to recover and resume healthy growth. They must have full sun to bloom. They will do fine in partial shade but will not bloom as well if at all. And of course good drainage is important.

 The above photo is the orange flowering variety purchased at a Home Depot in Corpus Christi, Texas over five years ago in a #1 pot. Planted in the hell strip, it gets full sun surrounded by asphalt and concrete on two sides. These photos were taken November 13th before the big freeze. The tallest vines are 5-6' tall.

Here I am pruning the vines before transplanting and moving indoors. What a shame I suppose to cut those blooms.

Are you nuts, thinks my wife?

Many branch vines.

Time to root prune. Not much left there.

Pulled from soil in original pot from the spring planting, a 10-12" plastic one.

Surprised to see such small roots?

 Pruning roots before taking inside.

Looks like a bonsai doesn't it? This was three weeks ago and today the plant which is set in a west facing window is producing  a flush of new growth. I'll create a new post during planting time in the spring.  Which I wish was closer than it is.
