Using A Bubbler To Root Cuttings


For some plants, especially cuttings that are more than a foot tall and thick, using a bubbler to root cuttings is a good way to go.

A bubbler is a container of water and an aquarium air pump with tubing and air stone. Once you have the air pump outfitted with tube and air stone all you need to do is fill up whatever container you'll be using with water, drop the tube with air stone attached and plug in the pump. That's all there is too it.

What this does is put a lot of oxygen in the water and keeps it from going stagnant.

Bubblers work exceptionally well on soft/greenwood cuttings like Brugmansia and seems to hasten the rooting process considerably compared to rooting in potting mix or vermiculite. The blue objects in the containers are the air stones.




This picture shows pre-roots on a brugmansia cutting that had been in the bubbler only 4 days and you can see on the right that a true root is just beginning to emerge.



And here is a larger version of the bubbler using a trash can with 3 foot tall brugmansia cuttings.



These are very inexpensive to set up and I think well worth the effort. I leave mine on constantly until I get the desired results. For more stubborn plants that are taking longer to show signs of rooting, changing the water at least once a week is advised.

I don't know about burgs. but this also works with other plants, I use my pond for many different plants, impatients, sedums, marigolds, many grasses, all canna's, hibiscus all like the shallow areas in the pond. Annual impatients add just the right amount of color around the edges of a pond.

I've never tried rose cuttings before! Don't have a clue if it will or not.

I love it X.....works great for my african violets.....they root in half the time...





I just cut styrofoam plates down to size of container...stick holes in it...label names of violets under the holes and stick into holes....2 or 3 days and you can see the starting of roots...

I have to try this sometime. Right now im using 100% perlite in plastic cups. Seems to work well, my yacon cuttings were rooting using that method.

I wonder if you could use one of those fish tank waterfall filters? (like this one, but I have 2 doubles)


I have a 45 gal aquarium with one 2in goldfish in it, if I could make the plates float (& not kill the fish...I guess) it could be used for something other than a space suck. DH went all crazy & bought it a week ago & I finally ended up filling it, buying the fish & feeding it lol I want to at least have a use for it.

You want an air pump .. not a filter pump.

Yeah I know what your saying, but wouldn't the waterfall circulate the water, preventing it from going stagnant?

I don't really know if the waterfall would incorporate as much air as an air pump and air stone - just might! I'm thinking also that some of the plants may not be good for the fish and aquarium water has nitrates and ammonia in it doesn't it?

A mechanical water pump can raise oxygen levels better than air stones. The theory behind air stones is they provide more surface area for the uptake of oxygen in the bubble. The problem with the average air stone is the bubbles travel to the surface and escape before the oxygen has a chance to absorb. It takes about 90 seconds for O2 to dissolve into the water from an average sized bubble. The air is long gone before that happens.

Yes aquariums have Nitrates. As far as I know Nitrates are actually beneficial to plant growth. In a new aquarium the ammonium levels as well as nitrite rise. After the Nitrosomonas and Nitrobacter bacteria colonize the levels fall. Ammonium gets converted to nitrite then to nitrate by the bacteria.

All of that information was basically irrelevant. How often can one use that knowledge from decades of aquarium keeping? I just couldn’t resist.
