My Wisteria is 17 years old. It has had merger blooms( 3-5) over the years ... What I have noticed is that it does not bloom in the Spring...It is Blooming now in August! Why would that be??
Like most plants, wisteria needs sun to bloom; vines that get a lot of shade simply will not flower, say the experts. Some growers feel it also craves phosphorus, the 'flowering nutrient', so folks with no flowers might want to scratch a couple cups of bone meal into the soil now and then add some rock phosphate in the Fall.
But the secret seems to be in the pruning. One of my best general plant books says to always prune after flowering (which, of course, is very cruel to people who don't got no flowers) and only recommends winter pruning to control the size of this often-invasive monster. But another good source say to hack away in winter, removing all but a few buds from about half of the previous year's growth in addition to the summer pruning.
We have had this Wisteria for about 3/4 years and it has never flowered. It just has very vigorous growth - Leaves and shoots climbing high. Could you possibly tell me how to prune (and when) so that we can achieve flowers, or is it too late? Thank you.
Your Wisteria needs a bit more time to reach maturity and to bloom. The average is 7 to 15 years before flowering.

Our vine is at least 30 years old. It was well established when we purchased this house in 1986. It has only blossomed every other year Andrea has never produced seed pods. This year we pruned it back to the thickest trunk part and it has already sent out new vine growth. It gets full morning sun. What can we do to increase blooming and fruiting? How often and when is pruning recommended?
What a wonderful vine to have!

How is the root system of this Blue Moon Wisteria: HOW INVASIVE CAN IT BE/GET?? Should it be planted away from building foundation structures?? How far will the roots reach/grow out from its base??
The roots are not what you have to worry about. They really aren't bad enough to do damage like a tree would. It is the top that gets a bit tangled. Just keep it cut to the desired shape and structure. Every year just remove the vines that are no longer wanted, Keeping in mind that you should always leave the large base stem for it to shoot from.
Can you use the pea pods to grow new plants?
Yes, these seed pods can be plant as you would peas. These are best sown directly in spring. These freshly grown plants from seed might take upwards of 15 years to see its first blooms, though. An alternative would be to start the vine from cuttings. This will ensure that the new plant is the same age as the one you took the cutting from, thus it will bloom within the first or second season.
