A good friend received a package from overseas order and had nothing but leafless vines....and a box of dead soggy leaves. With nothing to lose, I suggested they make a Hail Mary Pass and try rooting them anyway... This is how I do it in a shallow tray and using rocks to hold the vine down... there is a 50/50 chance which beats 0 anyday....   Leap. The net will appear. |

Am going thru my greenhouse checking on individual pots...and I found this with a pot inside of a hanging pot...  I really hate when this happens because there's a chance those dry roots will die and rot when I repot...but a chance I take. I cut the old pot off...and repotted in damp mix in the bottom....and will check it in about a week... Many times I simply fill the area between the pots with medium and they keep on growing.....

| Great visual, Carol. It's always worth a try. Who knows but what that would turn out to be a prize winning plant! |

| Hi, I am new to this forum and Hoya. I am completely ignorant about these plants but I am trying to learn. I have roots growing out of pot like you showed on my Carnosa and Wayetti. Can I simply trim off the roots that are outside the pot? |
|

| It's really not a good idea to trim the roots. Some growers do it, but they are very experienced and have a lose light potting soil. Hoyas grow in the wild semi epiphytically, sending out new roots along their vines to hold on and to receive nutrients from. In culture the poor dears have to depend on one set... They enjoy being pot bound so I would pot up just a wee bit. If you DO trim the roots, make sure that when you water the plant ALL the inner roots get wet. If the roots are coming OUT it generally means that they are looking for more water. You might check the root ball, they can get so thick water cannot get through.... Hope this helps. Leap.

   I was wondering if someone could give me some advice. I have the opposite problem in that while I have large and healthy looking leaves my roots do not grow and I have gotten no blooms. The first hoya I posted is about 30 years old. I started her from a cutting I was given. She's gone through kids, moves and puppies. The puppies recently resulted in several broken vines and many happy co-workers.Itransplanted it in a very tall pot with the bottom 1/2 - 2/3 filled with styrofoam peanuts and the rest potting soil. This plant has only bloomed for me once in 30 years. I think th is a Silver Pink Pubicalyx based on the leaves which are splashed with gray to pink and the deep pink flowers observed the one time it did bloom. Any comments on identification of this plant? The other two hoya are about 10 years old and again have great leaves but are very root poor. I just purchased a fabric nail to hold the Kerrii in the soil because it would fall out every time the dog's tail brushed past it. I've recently noticed some ugly black decay (?) on one of the Kerrii leaves. Could someone tell me if this could be a fungus or just the result of a cold draft, etc. I think the second plant is a Carnosa but if anyone could help me identify this plant, I would be grateful. My main question here is how can I get roots to grow on these plants so I can get some blooms to grow. I live in Colorado with no air conditioning or humidifier. I water my wax plants sparingly.

| I have never had luck with growing hoya roots in potting soil. I use something like this now and I have roots! http://cubits.org/AlohaHoya/thread/view/22279/ |

| Your plants look VERY healthy!!! Yes...I would cut off the leaf of the H. kerrii with the black spot. You are growing good hoyas for your conditions (not much humidity, dry)...especially the H. kerrii which is close to being a succulent. Why do you want them to grow more roots? They look very healthy! What fertilizer are you giving them? H. pubicalyx 'Pink Silver' and H. carnosa both 'seem' to like growing in lower light than full smack on sun...and they enjoy growing drier more than wetter. I would feed them a balanced fertilizer with a higher middle number than the other two numbers. BLOOM fertilizers are good. Instead of once a month application, I would give the fertilizer 1/2 strength every second time you water. ALL hoyas enjoy aircirculation!!! not stuffy rooms. Hs. carnosa and pubicalyx are good ones to grow cool (I once saw a HUGE H. carnosa growing in an abandoned house in Taos New Mexico in the dead of winter. I don't think it had been watered in a LONG time.... Not a good way to grow them, but they do take cool/cold temps better than most. I hope this helps.... Carol Leap. The net will appear. |

You are growing good hoyas for your conditions (not much humidity, dry)...especially the H. kerrii which is close to being a succulent. Thanks for the advice Carol. I'll try the bloom fertilizer before I try anything else but I have some newbies coming and I might try her bark on a few of them to see if that gives me blooms. I thought one needed a rootbound plant in order for them to bloom. That is why I"m concerned that they haven't produced mass amounts of root at this point in time. I was incorrect on the dates too. I got the biggest plant (pink silver) in 89' so she is only about 23 years old but she has done well for me. I have an office spot that is next to a window so my plants would get a good amount of sun in the wintertime. Unfortunately I am also right under the heating and airconditioning vent so there are often cold bursts of air summer and winter there. Will hoya (say a tricolor carnosa) do well here? Thanks again!

| Coralee...yes...they really like being rootbound...and it could be that you need to 'downsize' the pot they are growing in. As they are epiyphytic, they grow out looking for more space to 'root' and .... some will bloom before the roots are tight in the pot...but if there is too much room for the roots they concentrate on growing roots, not blooming. When the root question is satisfied, the carbs they use are redirected to blooming. SOME are not so fussy. But most are... There are some threads here on soil and roots and growing you might find helpful.... Caropl Leap. The net will appear. |

I cut that leaf off and started it in Hydroton about 3 weeks ago. The following picture is the result so far. Not sure what kind of plant this will produce but it will be fun to find out.  |

| Are the plants root bound? As hoya like their roots cramped they usually put energy into a healthy, solid, tight root system before they go into 'survival mode' and begin to flower. I think your second plant is H. australis. Black stuff sounds like rot...cutting it off is a good idea. HTH  Leap. The net will appear. |
