Wasn't sure what forum to put this under. But...wondering if anyone has had any experience making the hypertufa pots. I have some instructions, but was hoping to find someone who has actually made some, and basically tell me what NOT to do!!
Hi, Lacemosaic! Here's a link to another thread discussing hypertuffa pots...way down at the bottom, there's someone with "real-life" experience in making them. Good luck, and post pictures when you get them done - they're fascinating!!!
DH & I made one in a class at Powell Gardens a couple years ago. We made it one week and picked it up the next week. Depending on the size and thickness of the walls(they do need to be at least 2")it takes a minimum of 24 hours to dry. Several days is better. They are quite heavy in our opinion but were winter hardy here in zone 5. Do be sure to put a dowel, etc. in the bottom for drainage. Some people in the class really decorated theirs with shiny objects while the material was still moist. We aren't that creative so ours is plain grey. I'm certain we could add decorations now if we wanted to.
BYRON-----very interested in your friend who makes and sells them. Does he/she have a website? Where can I see what they do? Was hoping to make some to sell...was wondering if that was feasible, since they take so long to cure, from what I"ve read...can't wait to hear back from you!
Here is her methods
Actually, that's why I started making it. I had so many plants, and I was
living in a rented house, so everything was in pots. Hyeprtufa is a mixture
that ends up looking like natural stone. The recipe is:
One part Portland Cement
One part each of any TWO of the following:
I use peat moss and vermiculite. Sand will make your pots heavier.
Mix the ingredients (I use a cement trough and a hoe) and add just enough
water so that when you squeeze a handful a little water squeezes out. (You
will want a good pair of rubber gloves!)
I make my pots inside of molds. It's easier, and I think it looks better. I
use several different thingss for molds, the ones that work best are the
plastic "bowl" planters and sturdy cardboard boxes. If you use a box,
reinforce it with duct tape. Line the mold with plastic. I use cheap plastic
yard bags. Get the plastic fairly smooth, but a few wrinkles are okay and
will make interesting "cracks" in the planter. Press handfuls of the mixture
into the mold, keep it from 1 to 2 inches thick. The larger the planter the
thicker you will want it for strength. It's tricky to get the rim smooth.
Some people put small creek pebbles in the rim. I make my drainage holes at
this point, I just make holes with my finger. Cover the planter with more
plastic (if it's hot out you may want to cover it with a damp towel under
the plastic)and let sit in a cool place for at least 24 hours. CAREFULLY
unmold the pot. (I've had then shatter at this point!) It's best to unmold
them where you won't have to pick them up and move them for another day or
two. Re-cover with plastic for at least another day, then let cure two weeks
I color my pots. You can add cement coloring to the mixture, but it takes a
lot and gets very expensive. So, I sponge on color instead. I use both
cement coloring and acrylic craft paint. I do this on the day I unmold the
pot. I first uncover the inside, and sponge the color on the rim and a few
inched down the inside. I usually use two or three different colors. Then, I
turn the pot over, remove the mold, and color the outside.
I have also made some containers without holes, sealed them with concrete
sealer after they were dry, and used them for water plants.
Now that we have the directions for these, where on earth do you find perlite or vermiculite in packages bigger than 8 qt? I have searched high and low for these to no avail... 8qts wouldn't even begin to touch what i need. Would love to find somewhere i can buy this in bulk... Anyone have any ideas?
I think that you can buy vermiculite at a lumber yard or someplace that sells insulation?
Also, I know that florists use it (and maybe perlite too) to arrange flowers in containers like funeral sprays and such, so maybe you could contact some of them.
Hope that helps, Birdie
I have ben makeing the hypertufa pots, have 5 the last one I made i put the chicken wire over a 3 gal plastic nursery pot,formed the mix free hand on the out side rounded the top rim, added some bumbs for looks,punched out the drain holes from the plastic pot, wraped it all in a garbage bag, let it set for a few day kept it misted, left it a week.
The black nursery pots stays in this, is permanent, You get them in different sizes, with all the plants you buy, but they are tacky looking, no one wants to leave there potted plants in them, I want a pretty pot.
I shouldn't have to water my potted plants so much as they are in a plastic pot just covered with hyperturfa.
I have really enjoyed the hyperturfa, I'm not through yet.
