They will keep growing from what I've seen but always displays the look of chlorosis esp toward the end of the summer. You'd have much better luck with central Texas source. The only place I know of that sells it is Madrone Nursery in San Marcos where you can get them pretty cheap. Montezuma cypress trees at the neighborhood park has nice green color growing in alkaline soil on top of limestone rubbles so that's another option for you to try. Another option is to get montezuma-bald cypress 'Nanjing Beauty' from Botany Garden Shop online. It's reported to tolerate as high as 8.5 pH.

This is Nanjing Beauty at Dallas Arboretum during December. Holds its green foliage into January before displaying winter color. The director there told me it has grown very fast. I just planted one in my rocky limestone soil so time will tell how it'd do in alkaline soil.

I guess this is central Texas bald cypress??? The foliage is very green unlike other bald cypress trees around it in that neighborhood a couple miles from me. I have 4 or 5 seedlings in the container and has same deep green color as that one. It caught some of tree experts attention and wanted seedlings or seeds from that tree. Very low germination rates unfortunately.

I was talking to Texas fellow from Denton on Texas gardening forum about cypress and he said that his bald cypress looked bad but his montezuma cypress was doing pretty good with no chlorosis problem.

Might as well just give up those cypress trees and start over with cypress trees I suggested.

Check out those Montezuma cypress I planted at the park along with the picture of limestone rubbles that I have to deal with. I had MC for my neighbor today so we went to his backyard only to be very worn out from trying to dig a hole. It's only 5g sized tree but jeez all those rocks.... We're not even done. Have to finish it tomorrow. All the work for a little tree!

Another suggestion is to go to Stephen F Austin State University in Nacogdoches and collect MC seeds during the fall. If you wanted bald cypress, head over to Krause Springs in Spicewood (30 minutes NW from Austin) and collect some seeds. That is what I plan on doing for experiments.

Jeez lou.

MC as in digging a hole with Michael Carleone?

Lou, your second photo, the one by the driveway, is sure a fine specimen. I believe we,ve seen that one before. What an excellent example of local populations having adapted to their environs.

lou, the bald cypress I have that are sourced from the Guadalupe River have a color very similar to that BC tree you are showing. However they're only about 18" high so to soon to say much for sure. Have had 10 BC trees from National Arobor Day (2 left, other went to friends)and no signs of chlorosis, however the foliage color most distinctly does not compare to that of the tree in your picture or to my two Guadalupe River trees. Noticed that there are lots of BC cypress balls that can be easily attained from Town Lake BC in Austin for those who can germinate them. Those are also growing out of limestone rock in some cases. Thanks for the tip about the nursery in San Marcos.

The trees from Louisiana that I had potted in blackland clay were raised with the pots sitting in a tank of water with fish in it. Perhaps that soggy condition delayed the initial onset of clorosis in those individual prone to it, but the drier conditions after transplanting brought it out? As lou mentioned above, the drier end of summer can also bring out chlorosis.

Just had my first ever Bald Cypress seed germinate!!!
This is probably my 3rd attempt at Bald Cypress and finally one seed germinated! The seed are sourced from the Frio River so they should be as alkaline adaptable as Bald Cypress come!

Congratulation. I had zero success with Frio River BCs for some reason. I don't know why. Just very disappointed. The MCs from Nacogdoches seemed a lot easier to germinate and grow. Midlothian cypress (my town) was a bit tricky to grow and apparently lost all of them to damping off disease. I think the peat I used was terrible. Oh well. There's always next year!

Thanks for the info about Town Lake. My wife is from Austin so I can easily obtain them depending on where we're staying. My wife's sister lives close to Town Lake and wife's parents live close to Krause Springs in Spicewood so either way works for me. I occasionally float down Guadalupe river but unfortunately, it's not good time to collect cones. It's neat to see all those bald cypress trees lined the river as I float down the river. I need to get waterproof digital camera and take pictures of them when I go tubing there in July hopefully.
