HI...I'm doing some research, and I really would like to know what growing/cultivating questions really plague you the most. NOT identification questions...growing questions. Just fire away...I will be collecting all the data....

TIA...

Hi Carol...Im trying to figure out whats the main cause of bud blast?Is the cause overwatering when the buds are at an early stage?I've had sucess with Hoya finlaysonii with buds reaching maturity by keeping the soil bone dry for over a week while the buds were forming.When they reached about hald size I watered again and there was no bud blast.I also wonder if this is the same cause for leaf lose for the bigger leaf vareties like latifolia ,loyceandrewsiana etc?Is seems like the baby leaves fall off if watered too much??Any tips, thoughts Shrug!

Now that is a biggie!!! I have never had those problems...OH, once ....I did. And I think I determined that the plant was not 'ready' to support blooms....could have been it was starting to rot?.... Finlaysonii is one of those (like all the ones with dark veining in the leaves) that like to NEVER dry out...but they root rot easily...so I grow them almost semi hydroponically. Once I did that (semi hydroponically) I never had problems.

Plants will bloom as a survival tactic...they are struggling (about something) so they bloom in order to reproduce....

When I get back from a trip I am about to leave on (in a few hours) I will talk to the plant pathologist at the university about it. Everything a plant does - bloom, root, grow etc., is determined by hormones in the plant system...which has to do with carbohydrates etc. Are you giving a good balanced fertilizer (like the MSU?).

More on this later...but it's a great question!!!!! Hurray!

I had this bud blast problem with a number of Hoyas- callistophylla, kerrii, crassicaulis, cagaynensis and even pubicalyx. It is very frustrating. Now the plants have grown bigger, I do not see this as much.
I think plants were not mature enough and did not like change from dry to suddenly having water. I transferred some of these hoyas(kerrii, crassicaulis ) in bigger pots when I saw they were root bound. Of course that meant no flowers for a while but later plants bloomed really well. Looks like some just need bigger leg room.
Crassicaulis seems to actually love all the rain we have been getting. It drops buds when there is no rain for a few days.

My questions -

1.Is it harder to root tip cuttings or the cuttings with new growth? In my case I find it harder but may be I can do better with the advise here.

2.When cutting comes with peduncle /s, I find that it would not produce new buds and if does, they drop without getting big enough. May be the peduncle does not have energy to support the buds and I am happy to wait but I find that they(preexisting peduncles) do not bloom later or are a late/poor bloomer. Is that just me or others have same experience. Is there a way to improve this situation?

3.In some plants, peduncles delay rooting so they are cut off to speed up rooting. For example- Plumeria.
Is it better to trim off the peduncles to speed up rooting in hoya cuttings ?

There are no stupid questions, right? :)

Great questions!Ive just began rooting cuttings,so i'm still learning.I've been experementing with grow rocks...They look promising!!To early to tell yet.Hope Doug dosen't mind me posting a link to one of his new you tube videos,but it may answer your last question! Great video too!! http://www.youtube.com/watch?v=DTcXtaWpoYw&feature=player_em...

Thanks Jimmy, I watched the video .... he cut off the buds ...not peduncles but I guess it does imply that peduncle needs/takes energy away from rooting plant.
Doug, beautiful video as always and very educational. Thanks.

I find it interesting that even Doug is having bud blast as well.He was only getting two flowers from each peduncle.Maybe the buds need a ceretain amount of oxygen in the soil to fully develop??I had my Hoya lobbii bloom for the first time this year.There were about 10 buds roughly 2mm in diameater.After I watered it...I was only left with three that bloomed.When a new peduncle formed,I dedided not to water it until the buds got about 5mm in diameter,the watered it just enough to soak about two thirds of the soil...no water ran out the bottom.The buds didnt blast!!Did the extra oxygen in the soil help the buds fully develop??who knows!lol Ill be testing this theory on future buds! Rolling my eyes.

Hi, how do I know when it's okay to pot cuttings rooting in hydroton? Checked these today is this enough? First time rooting this way and I'm amazed they rooted so quickly.

How do H. pachyclada needs differ from other Hoyas? I have grown 5 different Hoyas for several years, 2 have bloomed so far, all are healthy. But every H. pachyclada plant and cutting I've bought has died. Some quickly, some grew for several months then died. I've grown them the same as my other plants with thicker foliage.

I had same problem with pachy. It is known to act like this . Some people do grow it well.

I grow it much like a cactus. I put it in rather light mix and then let it dry out for about a week before I water it again.

Deidra...I would consider those roots viable. Just make sure that the cutting is firm in the media and doesn't wobble around which will disturb the small roots. I would also add a bit of fertilizer to the media you put it in or water it in with a mild fertilizer. Don't remove the hydroton balls and make sure you don't wiggle the cutting around a lot so the balls don't rip off the leaves....

Totally agree with Marcy. Pachyclada (subquintuplinervis is another one) are quite succulent (notice thick leaves) and likes a really lose media with air around the roots and dampness not sogginess. Big Grin
