If the hoyas are putting out new growth, shouldn't I still fertilize? Even in winter? Maybe a little nitrogen? It just seems counterintuitive to not feed something that's growing. I haven't had hoyas very long. Only a couple of years.

I hear this is a topic of much debate. My hoyas are exclusively indoors, even in summer, just in case that gives some perspective to the experience I'm sharing. I see you're in Oklahoma, so I'm guessing they're indoors now for sure, maybe all year?
I have several plants that don't seem to care yet what season it is and they're still putting out lots of growth and others who have stopped. It makes sense to me, because all of my plants have different needs and personalities so I wouldn't expect them all to decide to hibernate at exactly the same time. I just keep an eye on each plant to be aware of what it needs, it sounds like you've done the same.
I don't feed my Hoya with the same fertilizer I use for my other plants. I wasn't feeding them at all, in fact. A trusted source informed me of using the miracle grow orchid spray fertilizer for hoyas. That same week, a second source mentioned great success with the same fertilizer, I figured it was a sign and bought some even though I am NOT a fan of miracle grow in general. I tend not to use their products just as a matter of personal choice, but my hoyas noticeably enjoy this spray (I actually don't use it on my orchids). One particular Hoya had looked exactly the same sine I bought it, you'd think it was a plastic plant. It responded immediately to the spray and began growing longer, healthier and fuller. Leaves look a bit perkier. I have only used this when the plants are in active growth, and I only do it every 10-15 days, so we're probably at the end or very close for this year. I probably wouldn't fertilize mine at all if I hadn't heard of this spray because I like to leave them alone like I do my orchids. This is an experiment that has happened to go really well for us.

I found a fertilizer from "Smilingworm" I want to try. It comes from Thailand. If anyone else uses this, I'd like to hear. I don't use Miracle Grow. My other plants are orchids too.Thanks, Adrienne for your input.

Oh, duh. Yes, in Oklahoma I keep my hoyas in the house in late fall, winter, and early spring. They can go out in summer but everything has to have a place set aside in the house. I haven't set up an outdoor area yet. My orchids would appreciate it as well. Two of my Australis seem to be napping but one is growing great guns. The Pubicalyx are both growing. Rotundiflora is napping. Various others are growing or napping.

I haven't heard of smilingworm but that does remind me of my favorite plant YouTube lady, Planterina, who fertilizes her hoyas with earthworm casings once or twice a year.

My sister lived in Oklahoma for a spell and I recall winters were no joke.
My pubicalyx is still growing, too!

Our ice storms can be extremely unpleasant. Not much snow, though. I've watched a few of Planterina's videos.

I fertilize year round. I spray everything with water soluble WEEKLY in the greenhouse from March 1-November 30. Jan 1, April 1, July 1, Oct 1 the plants get a foliar spray of micronutrients. And certain plants (palms) get granular on the same schedule as the micros. Some other plants also get Osmocote applied this time of year to slow release. These are mainly epiphytes in baskets with moss or orchid bark...the liquid will deteriorate the moss media really fast.
But when I say EVERYTHING I mean that, unless it is something that is clearly trying to go dormant. In which case I let it and say Hi again in March

Hoyas must be one of the most resilient plants on the planet! If they're fertilized, they grow, if they aren't, they still grow. I think I'll use the policy of growing--feed it. Not growing--let it rest. See what happens. You guys are all so great!

I don't give my Hoyas any fertilizer, and they still thrive. One of them is blooming right now too.

Does anyone else watch Summer Rayne Oakes on You Tube? Her apartment in Brooklyn, NY is amazing. I haven't seen Planterina, will check her out.

I watch her! I enjoy her plant a day series. I loved her video with the woman who was apparently involved in some way with discovering several Hoya and she went to her home and saw all her plants. Maybe it was in Norway? Or Sweden? Did you see that one? I may not have all the details correct on that one, but it was one of my favorites.

I like how planterina is a little more candid and human about growing. She shares when things don't always work out and I love the videos in her garage. She recently started a company and after months of watching these videos of her touring the greenhouse and talking about what she'll be selling I was kind of disappointed with the plants they're offering. I thought I'd be swinging from linearis arms to get from room to room based on her videos. Nary a linearis to be seen last time I checked.

Sometimes Summer's verbiage is a bit harder for me to relate to. When she says "I put this plant in 30% sun" I find that a bit nebulous. I like how planterina says "we're going to put this guy in an East window and it'll be happy." She was also my inspiration for hunting down my giant epipremnum totem. She has to be the queen of massive indoor plants on a totem, and I want to try her teepee method.

Anyway, yes! I love how both offer resources for indoor gardeners.

Yes Adrienne, I saw that one too. My goodness! She has it down to a science, lots of good information.

Just watched a couple of Planterina's videos. My house is not big enough to grow some of those monsters, and hubby already raises his eyebrows a lot when a box arrives or I say I want to check out a plant department.

Since all of my hoyas, except the compacta, are sending out new growth (plus I found a peduncle on one of the ones that came today and 2 spurs on another) I sprayed them with Spray and Grow mixed with Bob's Perfect Fertilizer. I had not fed them before, we shall see what happens.

My husband loves the plants, but he does generally draw the line at going to more than one Lowe's in one day. He'll do a nursery and a Lowe's, or a Lowe's and Meijer with the good plants, but two Lowe's = too much.

I haven't heard of that fertilizer before. Let me know how it goes!
I put a few Hoya under an extra grow light yesterday, mostly the ones that are still growing, just to give them something extra.

No I do not follow her.
I am sorry, BUT the real aroid people believe she is just a flash in the pan opportunist

I'm sure many of them are to varying degrees. I'm sincerely ticked about that planterina webpage. When I was first getting invested in my plants, however, I needed a jumping off point to learn about some plants that frankly scared me me to death. I think, in a way, they can be a gateway to more legitimate sources of information and that is probably their most valuable contribution IMHO.

I watched Summer Raines Swedish Hoya lady video. I liked it, but I don't care for her others. I watch Doug Chamberlain's videos but he's not the best on culture. Has had an incredible collection. I'm glad I found this forum.

Tarev, which hoyas do you have that don't seem to need fertilizer? I want to know if I have one. Maybe I'm over feeding.

I have been growing Hoya for over 50 years and I don't purposely fertilze. They may have inadvertently been fertilized because I was watering and happened to have fertilizer in the watering can. They are in constant bloom and grow well. If your Hoya are not blooming and growing, look for another reason, other than lack of fertilizer. We rely on the fertilizer crutch way too much, thanks to the fertilizer companies with big advertising budgets. No one is fertilizing the Hoyas out in the jungle, hanging from a tree.

So, my opinion, yes, you are overfertilizing.

PS: I still have my very first Hoya - a red blooming Hoya carnosa, still in its orginal pot with mostly original soil.

Adrienne. What's the "teepee method?"
