Inspired by reports from people that have tried it with success and, in particular, by the article here
https://www.growingwildnursery..., today I did it, I moved my Baptisia 'Blueberry Sundae.' Not the best time to do it, in the middle of July, but I just couldn't stand it anymore. It's a gorgeous plant that deserves the right spot. Here is a "photo essay" of my efforts.
This is why I have to move it. I have learned to never trust plant tags or vendor websites. I should've listened to the Mt Cuba trial report, which says that this grows to 3.5' tall and 6' wide. That's exactly how big it gets in my front garden. It's 3' x 5' in this picture, but will grow a bit bigger by the summer's end. It's hiding a mountain laurel and holly behind it. A beautiful plant should never be so out of place that it is hated!
In the evening I removed most of the foliage. Most of the plant is now on the ground.
Next morning I started excavating around the plant. I've heard you have to use loppers or even a saw to cut the roots, but these pencil sized roots were cut with a hand pruner.
I went all the way around, using a spade, then cut underneath with a shovel. I tried to keep the root ball intact, but the sandy soil broke apart easily.
Here is the plant out of the ground. I was able to save about a foot of roots all around. No big central tap root, like I've heard.
A close-up of the roots, showing the nodules that house nitrogen-fixing Rhizobium bacteria. Baptisia, a member of the pea family, is a nitrogen fixer.
This time I'm smarter and have the proper site prepared. The hole was the perfect size for the roots. Yay!
The planting hole flooded.
All planted!
I'm documenting the process here, in case someone else wonders about moving a baptisia. It took me about 3 hours from beginning to end. Baptisias are beautiful no-care plants, but their tremendous width means that many a gardener will have to face moving them! I hope to be able to say this fall that the plant is surviving and, next spring, that it's back to its former glory. Even if it sulks for a season, that would be fine. Wish me luck!
