Hi everyone,

I just read that Pachypodiums enjoy a highly acidic soil (4-5.5pH!) ....does anyone have any experience with this, and if so, how do you make your soil that acidic? I'm using them in pots. I've got one P. geayi planted, one mystery pachypodium I found at a yard sale, and I just ordered some P. eburneum seeds. I love them and want the best for them. I have seen two enormous specimens here in Bradenton FL and on Longboat Key...so they must grow here under some circumstance! Shrug! Thanks!

Mine are mostly in our 'regular' soil which is pretty much all sand and are thriving. This is P. rutenbergianum.

OK! I love your rutenbergianum!

Do you have any experience with P. eburneum? Also, do you know what kind of pachypodium this might be?




Sorry for all the questions, and thank you!

Only the blooms will tell exactly which Pachy that is - It looks a bit like P. saundersii.
Check the poster with Pachypodium flower pictures for handy identification.

No experience with P. eburneum I am afraid.

Oh my. Well I guess that will take a while!

Have you ever purchased plants from that site?

Yes. They are a great outfit located right here in Naples (and I did get to tour their place, but they don't sell from the location, everything is by mail order - but I had a 'connection'...)

Kate,
You can lower your ph safely by using Sulfur sold for Analyzes and Holleys. I think it's called 'Holley Tone'. Mix with water and just water it. I have used this for my Sansevierias, then all my African succulents like Huernias and Stapelias. I don't think you can lower the ph down to 4.5 but close. To go much lower you may have to go a purer sulfuric acid or battery water. It gets very dangerous at that level for both you and your plants. I never heard of going down that low. Usually 6 - 7 is good enough.

Thanks Stush! So you lower the pH for your Sansevierias, stapelias & huernias...what else would you use that with? I got some of the sulfur stuff you mentioned. I was thinking it would be good in my "tropical" plant garden...with alocasias, philodendrons, strobilanthes, ferns, chenille ground cover, dracaena, taccas, diffenbachia, etc etc...

Kate,
Maybe but I don't know the ph range for those plants. I used it with my jade plants as well. It helps stop root fungus and used with a little phosphorous gives them a boost. I know annuals seem to like sweet soil as well as your veg. garden plants.

Kate I have read that all cacti do better using acidic water, don't know the numbers, but I agree with what Stush said about 6 being good! This is a good and interesting question! Thumbs up
