Barbur, I dont't know about vermiculte and perlite, but you can get zeolite in huge bags like 40 pound size. I think I bought mine at Gardenville in San Antonio. It's worth a phone call. If they don't have it, they might know who would.
I've added zeolite to some of my potted plants that like lots of moisture, like rabbits foot fern and a jasmin that I just bought. I've had it for a long time and just never used it. I've read that you can add it to flower beds too. I did use once to clean up an oil spill we had in the garage.
Has adding zeolite made any difference in how often you water? I have a bunch of Brugmansias in pots and wonder if adding zeolite would allow me to reduce the number of times I have to water without making the soil too wet.
This is the first year that I've used it this way, but I either read or heard from Malcolm Beck that you can use it that way. Atleast that's what I understood him to say. I have a brugmansia that might appreciate some zeolite too come to think of it. If you put them in the ground do they establish really deep roots and spread way out? I have considered using it around my roses in the ground, but it seems to me that it would be counterproductive, because roses need to send down really deep roots and there's no way I know of to get the zeolite down that far. If you used zeolite in the first six inches or so it seems that would encourage the roots to stay in that area and be more susceptible to freeze damage. I don't know. I think for vegetables that have shallow roots it might be a really good idea.
Roses have very shallow roots and working the soil around them is not advisable. I haven't tried putting Brugmansias in the ground yet, but a lot of people dig them up to overwinter indoors so the roots can't be all that bad. I think it would work on vegetables.
I am also looking for bulk vermulite.
Nothing at all up in this area. Thought if someone knew of where to get some before Daves roundup t;he 29th of May in Collage Station, Texas is would be great. Would be great trading material.
TARogers5, In another thread someone said you can get bulk vermiculite at Southwest Fertilizer at 5828 Bissonett St. in Houston. I looked it up and they are also referred to as Yardgeek.com but when I searched for vermiculite nothing came up. I emailed them so we should be able to find out.
I went to Garden-Ville in San Antonio over the weekend. They had 10 lb. bags of perlite but no vermiculite. Also went next door to Antique Rose Emporium, what a beautiful and interesting place. I'd been to the one near Brenhem and was so impressed by the beautiful gardens. Though the SA one is different because the area is so different I was no less impressed.
Yes, I've been to the Rose Emporium (both places) many times. I live in Fredericksburg, which is 1 1/2 hrs from SA and 3 hours from Brenham, but it's worth every penny it takes to get there. It's just fascinating to study their gardens. Everytime I go there's something new. And the people are so knowledgable and patient with me. I've been so many times, they recognize me.
There is one major difference between them though. The Brenham location is not entirely organic but as far as I know the SA location is. Robby, the manager in SA has been a big help to me.
Absolutely you can do it. It's so much easier and safer. There is a nursery here that bases their advice on whether the plants you're growing are fungal or bacterial. It's a whole different approach, but still organic. It's really fascinating. They tell me that roses are fungal, so using alot of cornmeal is not necessarily a good idea because it kills all the fungus, not just the bad stuff. They told me to use humate, so this time I did. I just fertilized yesterday, and can wait to see the difference. There's also some spray I bought to use, I think it's a fish emulsion.
When I realized I could grow roses without spraying all that poison stuff I went crazy and now I have atleast 20 roses. It makes so much more sense to feed the dirt and let the plants figure out what they need.
