Does anyone ever plant a Hoya in ground?
If you do, which variety did well in your experience ?
Also,please share pictures if it is possible if you have any in ground.
Thanks in advance.

If you can wait until this afternoon or tomorrow, I will take photos. I have LOTS growing in the ground, mainly eriostemmas which do well. I have put H. imperialis in the ground...but our 'ground' is only about 3" deep over lava and the trees compete for the nutrients. Remember, hoyas like their roots tight.

I have also grown them in pots at the foot of trees....that works. Foliar feeding is necessary. Big Grin

I have a few in the ground, and I'm planning of putting a few more in the ground this Spring. I took Carols advice and mix a lot of Lava Ash into the ground, I also add broken pots...anything that keeps it loose, around the roots....but I wait till they are decent sized plants before i do it....H carnosa, pubicalyx, fraterna, australis, crassicaulis..will try a few more. We have a very long dry period in the year.....in fact this winter it has only rained twice............and only for an hour....so the ground is very very dry.....gonna have to wait another 12 months for the spring flower exposion this time Sad
Have actually had to wash my car this year....... Thumbs down Thumbs down
I cant remember the full details..but someone planted a H serpens in the ground somewhere, sometime, as she was sick of trying to get it t grow..she then left the area, and it was mistaken as growing wild there years later when it was found flourishing......cant remember the details...but you never know.

I've also found they grow especially well onto rock..especially when you dont want them too.........and into Lava Ash. Both these ways they produce roots like I've never seen before. I've tried rooting in the lave ash, but so far no luck, yet they layer beautifully............ left to their own devices, some of mine have rooted into ash when a stem touches the ground....and there can be more roots on that 'touch' than in the pot of the whole plant. I have a H diversifolia that has just rooted itself thru the bottom of the pot into the ground arnound a palm......I'm just going to have to let it have it's way with the Palm now and climb as I just cant move the pot.....its very firmly rooted itself into the ground........

Wow, I can hardly contain my excitement. Please, please, please post pics of these Hoyas growing in ground. Big and small,pretty and not so pretty,blooming or not....I will love them all.
After all they are not always lush looking in their natural setting.

Carol, I love looking at the pics of your Hoya growing in natural way,specially ones that are climbing here and there in 'wild'.So,yes I will wait for you to post pics....please make it soon... Drooling

Here we hardly have 2-3 inches of 'soil'.That too is only when we are lucky or if we keep dumping bags of soil on our sandyland. All sand here...and the rocks whenever you dig. Rocks are limestone I think.....very rough and they have the look of sea shells/oyster shells embedded in spongy concrete.....wonder if Hoya would like them .
I use them for edgings . Hawaii soil may be richer in nutrients though. Our soil eats compost for snack.And I think if we dig and dig and dig,we will find all our compost on the other side of globe .

Alka...so much limestone tells me that your soil is very 'sweet' (i.e. alkaline...high pH).

David Liddle took a pH reading from every site he ever collected a hoya from. He said it was consistently between 5.5 and 6.5. NEUTRAL is 7.0 so MOST hoyas enjoy just slightly acid. Ted Green says to add calcium to eriostemmas...I don't add it and they take over the forest...but perhaps in home cultivation it helps. Personally I feel only a few eriostemmas will grow in 'captivity'...

First, Alka, I would get your soil tested. With all of the land I have here...it is easier growing in pots even if they grow up a tree 50'...the enviornment is easier to control and I am really into EASY!!!! Calcium IS important for all plant growth (it is essential for cellular strength) and the easiest for me to use is Dolomite...but I do NOT add it to any of my hoyas.....

Thanks a lot.
I have Oak, Magnolia, Palm , Plumeria,some vines and a few fruit trees in ground and they are growing fine, without much supplemental feeding . I even have an orchid growing in ground ( probably African spotted orchid) which has seedpods now.I do not know how it got here. Long time ago,it used to be part of Everglades, I heard. I think soil here in general is slightly alkaline....I mean everywhere. I dump compost in the flower beds and also under flowering/fruiting trees sometimes. But if all this stuff grows here and these things need some acidity,soil must be OK.
Main thing we worry about here is soil nematodes (small size and they go for roots). Grumbling
I guess they can potentially harm roots of Hoya if I plant any in ground. I do not use pesticides but I have not had much problem with nematodes......yet.

What about calcium? I read somewhere about Calcium and dolomite for changing soil pH but I can not remember details.

Carol,do you think any particular variety will do fine in my soil? I may want to try in distant future. Of course, I will have that plant in container too...in case one in soil goes to Hoya heaven.

Anyway, I am primarily interested in just seing pics of others Hoya in ground.Not so much about growing my own....... Smiling

Alka....maybe it's easier to think of hoyas being similar to philodendrons: there are climbing hoyas and there are 'selfheading' ones (think odorata, etc.). While some forms like H. odorata, cummingiana etc. don't scramble along branches like, say, H. lacunosa or H. imperialis...if their 'stem or branch' rests on a branch/rock/patch of moss it will root. While you can 'plant' a hoya in the ground, it will not live from that root 'in the ground'....it will root at every place it touches the trunk/branch and the root area in the ground becomes unnecessary.

Case in point: philodendrons are extremely difficult to kill: they grow up trees in a large mass, finally reaching the top, with nowhere to go they reach out and down and soon the weight of this mass breaks the branch they are on. In order to kill this vine, you have to rip every single rooted part of the stem off the tree....this is every single node!! To kill it with herbicide, you have to contact every single leaf with the poison...and you may be left with a node rooted to a branch because it didn't have a leaf to take the poison to the node.

Another way to look at it: every single node has the potential to be a different plant and infact, every rooted node is it's own energy source for the plant.

A hoya will not grow 'in the ground' like a plumeria or a ground orchid using that ground root as a base.

Even Eriostemmas, considered terrestial, root along the ground as they grow towards a tree and they DO ROOT TO THE TREE as well; 1) for support and 2) for nourishment. Hoyas can start anywhere: a crack in rocks, a crotch of a tree, in the root mass of another plant growing in the tree.

I can show you photos of hoyas growing in trees, up trees but they are NOT growing in the ground. Does that make sense?

OK. Got it. Also got to figure out a tree to experiment.How did yours got on trees anyway? Were they hanging there and the branches just took off?
Can I see photos of hoyas growing in trees,specially close up of roots on the tree,please? Big Grin

Yes...took a photo of a pubicalyx growing in a tree and pulled off a vine to show the roots.... Battery is charging....

I generally hang mine in the pot it is growing in. Once the vine is established in the tree with at least one root, you can cut the vine away from the plant in the pot and keep growing it.

OK...this first photo is Bob holding the pot....just above it is the severed stem (it was dead anyway) of the H. magnifica...growing happily in the tree unawares that the pot is gone. I cut it down about 3 weeks ago. She is rooted all over the tree!!!Thumb of 2012-02-14/AlohaHoya/4684bb

Here's the photo of the pubicalyx growing from a pot...all thru the tree.
Thumb of 2012-02-14/AlohaHoya/014307

Here's the root system where the vine had rooted, just above the pot...and actually where ever it decided to in the tree. I am SO sorry it is blurred, but you CAN see the root system...some major roots and lots of little hair roots. THOSE are what the plant is getting it's nourishments from....!

Case in point...we are growing hoyas in pots where they have one root system to depend on when they really, in the wild, have many points of contact to nourishment. For this reason, I think it's a good idea to let your plant throw down some roots along the vine in the pot it lives in. If the root system in the photo is happy...

Oh my God. It looks like a dreamland. Carol,can I move in with you? .......Just kidding.
It is so beautiful. Your garden and hoyas look very lush and happy.And what is that plant with red leaves,in first picture? Looks like a Bromeliad . Is it in a container or just bungee jumping.
I am not sure if I can grow outdoor as good as you have them but i can try and see.
Thank you,thank you. Lovey dubby Lovey dubby

OH...yes...that red plant is a bromiliad...they grow epiphytically and often totally cover a tall trunk. Great breeding ground for mosquitos!!!

Thanks for the compliments...Gave up having a neat/controlled garden years ago...controlled chaos is the best I can do!!! and that controlled word is really iffy!!! Big Grin
