Let's talk about humidity for hoyas

Today we are going to talk about something I think a lot of us got hysterical about at one point - what humidity is good for my hoya (but also, a lot of these apply to all plants in general). We will talk about what is the best way to up the humidity, is it really necessary and what hoyas will do well in lower humidity and which ones will be divas about it and requier high humidity to grow well.

Thank you Miro! Excellent video! I know a lot of KZbinrs aren’t fans of care videos- but this is a forte for you.. effortless. I love how you speak from your experience and there is no arrogance. The words just flow. Thank you again. 😊

[@viclarock5321]

Miro, your humor always makes me laugh. It is a joy watching your videos 😅

[@beeng77]

Absolutely loving your hoya summer camp, I watch it through out the week multiple times 😊😊. Really thankful with how thorough you are and name specific hoyas with different care to each other as most of the times hoya care is so generalised despite many having different water, light and humidity needs.

[@samtata5632]

Except for short summer , my hoyas survive in low humidity . I can see they struggle growing new vines and leaves compare to a perfect environment , but it is tough love here , and we work for each other , I try and do what I can to make them comfortable on apartment shelves , in return they work to provide mental health for me .

[@BasiePlants]

There are many species i find quite reselient, beautiful and willing to grow even under 50% :D And those who don't want to... well, they can go back to the forest :D

[@margaretwoodfield6220]

I live in Austin, TX, I put my Hoyas outside in the summer. Everyone grows! There are in the morning indirect sun. I put them into my Rudsta as it cools off here. One good thing about the summers here!

[@TheQueensWish]

I live in San Antonio. Hi neighbor 👋. I’ve got a lot of mine outside on the shaded patio. Good growing conditions in South, Texas. One of my Obovatas is from East Austin Succulents. Love that place. If you need more Hoyas, try Wild Roots in New Braunfels.

[@faegoyle777]

I grow most of my Hoya outside spring and summer. However, that comes with issues, like pest, fungus and possible injury to plants. Its a balancing act. Usually i have small cuttings for my most favorite JIC something happens to the mother plants. Late fall here in Florida is when i Usually start my task of bring the plants indoors or closer to enclosed areas. I'm fortunate for living in a subtropical region.

[@britteliz211]

I get so excited when you post! You’re so knowledgeable and thorough. I’ve been growing hoya as a collector for 5 years and I learn something new every video! ❤️

[@BasiePlants]

That is such an amazing compliment! Thank you

[@Miles_Hoffman]

Thank you for covering this topic. Las Vegas 116°F today, humidity is about 8% on a good day. Sometimes we get rain but not often. In My Home humidity stays at about 32%. Most fair well, but I have a few I have to keep in my aquarium that is just plant- light- humidifier.

[@traceykusser368]

Oh my goodness, you make me laugh! You describing your grow tent, 😂🤣, are we even talking about plants anymore? I monitor the humidity in my house and it’s usually higher than 50%. I do have humidifiers that I can run when it’s especially hot outside and dry inside. You are so right about the dust on the furniture! Major drawback.

[@BasiePlants]

Wait, are we not talking about plants?! :D Yeah, I used to filter my water and still got calcium deposits on furniture and the humidifier even has calcium filter. Basically everything is a lie.

I like how my green carnosas perform outside in summer in north-west Germany. Very succulent small leaves, shorter internodes, faster growth. I have some pubicallyx next to them, but they struggeled to adjust, while now growing more succulent like the carnosas and with brownish baby leaves. Hoya kerrii sunstressing quite lovely and putting out a lot of peduncles, but I dont like them anyway. The largest transformation I have seen on my Hoya australis. It was so boring, grown inside. Just dark green and flat, mostly round round leaves. This has changed, oh boy. The new leaes grow with brown topside and almost glow from the inside with fade to a neon like green with very pronounced veines and taco formed until they become flat as well, but with 30% larger size. Hoya latifolia with white margins is still in the struggeling phase but already shows some signs of liking some direct sun. I put Hoyas outside only, when I have a backup plant, so unfortunately, more results will have to wait. I threw some cuttings into leaf litter under trees or bushes in my garden. They quickly rooted, but then stopped to grow, but this maybe due to the dropped temperatures these days, with a lot of rain. And I mean a lot. Thanks for the video!

[@fabiennebovis-higgins7149]

Thank you for the very thorough videos. My hoyas are spending the NZ winter outside as it’s not really cold (hardiness zone 10B) - but I have put them in an unheated greenhouse to protect them from the rain. They will come out of the greenhouse in the spring but remain outside.

[@amberclear7016]

I use pebble trays everywhere my hoyas sit. Helps a lot locally. Thanks again for the video, Miro.

[@1ebonystar]

Miro , thank you so much for the summer camp videos. Continue being you💕💕

[@georgetaivanovici1135]

Thank you for this lesson, it's very educative. In Bucharest, Romania I increase the humidity using aroids. I fall in love with some of them (Anth forgetii, Philo lupinum, Epi Snow Queen). Love and interest, in my case because, my Hoyas have their aroids companions and it's works better than before and it's nicer.

[@deborahmcsweeney3349]

This was so good! I have found that in summer when it is hot, like 104F today, my plants cause the humidity to increase in my house. I do not use AC so my house is just shut up during the day. By evening the humidity has been really high even when it is really dry outside. I think they are making their own happiness! Lol

[@BasiePlants]

They definitely can do that :) I tent to keep all of my shutters open to allow the light in, but of course, that heats up the house.

[@deborahmcsweeney3349]

@@BasiePlants yes! We open the windows at night when it cools down and normally in the morning I would close curtains, something like a dark cave! Lol But now I can't do that because all of my hoyas are hanging in the windows! Lol hoping some day they will create a living curtain! With lots of flowers too! The only one I am really challenged with is Hoya fungi. It is just not happy. Lol

[@smerida8]

February here in Texas. 67% humidity. Always humid here. 🤷

[@InWesternLands]

I'm in Vancouver, Canada. I grow most of my hoya outside April through September with success. I keep them heavily shaded and in a shelving unit grouped together to create a microclimate with higher humidity. Being near the ocean, the humidity is usually around 60% outside. I usually spray everything that looks dry twice a week with a hose. I bring them inside when nightly lows are below 10C (50F). I find growing outside wakes up any plant that has been sleeping instead of growing.

[@BasiePlants]

How do they do with such low temperatures? Or maybe a better question - do you also grow warmth loving species like undulata, mitrata, patella, amrtia/ platycaulis? Can they withstand those? :)

[@InWesternLands]

@@BasiePlants Most of the summer has highs of around 25C and lows of 15C, so not that cold. I tend to stay away from cool or warm growing hoya, and stick to the ones I am confident I can manage, but maybe I should try some cool growing hoya. I don't have any of the warm growing hoya you mentioned, but I put my orchids, aroids, etc. outside also.

[@susanjohnson5824]

Thank you - great series lots of good information

[@BasiePlants]

I am glad you think so :)

[@jennifermizrahi98]

Great video. I grow outside and I’m in a very arid and very hot place in California. I grow all my Hoya in shade and they all are outside. I have to water probably more often but so far they have done really well except for the Hoya lacunosa. Damn that one!! I do have Hoya rotundiflora inside in a small pot. But frankly, I do not like growing Hoya inside or frankly… Any plant. Thank you Miro. Xo

[@harestyles]

Miro, you put such a smile on my face! You're engaging, funny, and so informative! Thank you again for another awesome video!

[@MelissaWalker82]

well said and well done!

[@herrenfam]

Another great summer series video :) This past week before our monsoon rain rolled in, it was 8% humidity here. An interesting comparison to your area’s humidity: our HVAC unit’s smart thermostat has an alarm when it reaches “extremely high humidity” levels that can damage the unit - 45% 😅 It did that yesterday when it rained. I know, unusual. I used to try and use humidifiers earlier in my plant journey when I was more of a glutton for punishment. Now I have cabinets. All my larger Hoyas are out in the open, but I’ll say that the plants in the cabinets grow much faster!

[@leannhillier-jv8wf]

Another very helpful video! I’m loving camp. Won’t want to go back home😂

[@BasiePlants]

Haha :D There will be other fun things :D We never have to leave the Internet xD

[@user-rv4jw4qr7z]

Hello, One thing we can also do to have more humidity around our plants is to grow them (all together) on aquanappe. And then we can water it or, more simple, water our plants on it and the water get down through the pot to the aquanappe. Much more effective than putting a "bed" of leca 🙂

[@aliceborolien]

👍🏼👍🏼👍🏼👍🏼Thank you 💐❤️ I learned a lot in this video too 😊🌹

Hi Miro 💫 I was so happy it was Hoya Summer Camp video time. Although, if I’m honest ~ you are just a gem to watch. I absolutely love your knowledge mixed with the Miro humor 😊 Honestly, you get another gold 🌟from me. Can’t wait for the next video 🙏🏻💫

[@paigemcmaster5040]

I have almost everything I own in my grow tent which is 5x4 feet. It stays at like 70-80% humidity (without a humidifier) and never gets colder than 23 degrees. AND I live in Canada where it gets super dry. I think it helps that I have philodendrons on moss poles mixed in with my hoyas - keeps the humidity up.

[@BasiePlants]

Yes, big leaved plants definitely help with my humidity a lot :D And of course, moss poles :)

[@TheQueensWish]

We are 39 days now of daytime temps at 100 F or exceeding that. No end in sight. 26 Hoyas are living outside. Today was 104 F. Humidity varies but is high. It is hot! Philippines hot! But this is not the Philippines, it’s just our summer in South Texas. I worry that the temps are outside the tolerance of these beautiful Hoyas but somehow they are okay as are the other plants. Shade and water are the only comforts they enjoy. All the indoor Hoyas live in air conditioning and lower humidity.

[@PD-jamp]

Lots of great information and experience here. I keep thinking about buying a grow tent, but the space and the aesthetic don't appeal to me. Plus people will think I'm growing something else!

[@BasiePlants]

Oh people def think I am growing something else since they can see it through the street window. If I were, it'd certainly bring me more money :D and maybe I'd be less sour :D

[@heidikimball137]

I had a swamp cooler installed due to necessity. Living in Colorado is challenging as a plant parent. The increased humidity has definitely had an impact on my Hoya's. I've finally had a few bloom after waiting for several years. Great episode!

[@BasiePlants]

Yes, they are not going to say no to it and some absolutely need it, but so many do well without it :D Since I can provide higher humidity with almost no effort, I am fine with it :) If I had to go out of my way a lot, I probably wouldn't do it.

[@darrinseelye2091]

I live in Colorado and have amazing plants with zero added humidity. I swear people think that plants pull water out of the humid air in their house. The reality is the humid air slows down evaporation. The key is to mimic the rainforest and understand how to do that within your environment and the media the plant is in. In a rainforest there is morning and evening dew/mist caused by a crossover in dew point. Constant water on the root system being kept there by little to no evaporation and plenty of air flow on the root system. The actual humidity is kind of irrelevant.

[@plantingwithnat]

Miro, you always look fabulous😻. I have a humidifier, but I don't use it. The reason is my humidity is between 41-46% without a cabinet my plants have been fine without it. They are growing, and if they do need it at least I have it on hand.

[@BasiePlants]

They will do really well in that humidity :) I really should have measured my humidity before purchasing the humidifier :D

[@plantingwithnat]

@@BasiePlants 😻

[@carissaseguin2283]

My Hoya Krimson princess, polyneura, linearus, and compacta have done well in regular room humidity where I am about 25-30% in winter and about 35-40% in the summer :)

[@BasiePlants]

Those can do great in lower humidity indeed. A bit surprised about linearis, but I guess it can do well with regular watering.

[@sallyfeldman1256]

I live in the northeast USA with long cold winters. My house humidity will be around 30 for the winter. My plants….Hoyas included are all grouped together in a south facing window with a humidifier on 14 hours a day. Oh, I forgot to say, a wood stove runs in this room every evening. I can get the humidity level up to 40 but that’s it…. The house has more of an open floor plan. I haven’t lost a plant yet. They may just sit there for the winter but then they grow great in the spring/summer.

[@BasiePlants]

Ah yes, wood stove will also dry out air more. :) I think 40% is good for most of the species :)

[@kcgrows]

This is a timely episode, as always! My huge beautiful multiflora that flowered constantly for 6 months lived in my Milsbo before dropping all of her leaves in winter. She was growing in LECA. I was able to cut the plant down and successfully propagated two leafless stems in moss. It’s back in the Milsbo and I will keep it in moss, but I’m worried about the high humidity and low temperatures (it seems to like the heat of summer) in the winter because she still needs to stay moist to flower and be happy. Thoughts? EDIT: Also, should I try growing it in small bark to be less wet in winter?

[@litalfrenkel1024]

Miro thanks. I also think that maybe when you start a hoya from cutting or very small plant its growing adjusting to your environment as appose to big mature plant that got used to the comfortable nursery conditions. Maybe.

[@jelenamitrovic9039]

Getting the room humidity up to at least 45% is something I completely gave up on. I think that industrial grade humidifiers would be the only ones to actually have a fighting chance in my appartment. I had a humidifier in my grow tent - it worked well, but I never used them in my cabinets - they were never needed. Even when room humidity was 20% cabinets where easily at 60%. So plants were fine, and I am just used to desert conditions by now 😂

[@BasiePlants]

Hahaha :D I swear, your apartment just leaks someplace :D Never have I ever seen a place that refuses to be humid. Yeah, but let's be real, that humidifier was work. If I were you, I would not even try :D You are much better than I am that way.

[@kristiemowry3267]

I have an evaporative humidifier that automatically comes on below 50%. It was very inexpensive and holds gallons of water so rarely has to be refilled. No one seems to be aware of these, but they are wonderful.@@BasiePlants

[@plantingwithnat]

Miro, I know you mentioned in your video that you do not have a humidifier in the tent, but what about the cabinet do you add the humidifier, or do you use a weather strip to keep the humidity in? A video suggestion could you make a video on how you set up your cabinets such as light, shelves, air flow, and humidity.

[@flatcreek4665]

Miro….I’ve been dreaming of a IKEA greenhouse cabinet for over a year. I’m just curious, do you prefer the Milsbo (tall or wide) or the Rudsta? Another great video. Appreciate your content so much!

[@BasiePlants]

I don't have wide Milsbo :) It depends. I can fit about 24 hoyas in 12cm selfwatering pots on 30-40cm trellises in my Mislbo, in 3 leaves. In rudsta, I only have 10 hoyas on one level and the bottom level is not so usable. The Rudsta has gone a lot in price, so I'd probably choose Milsbo. It also depends what you want to do with it. :)

[@PetraEmmy]

Thanks for another hoya wednesday video! I don't even use a humidifier for myself so not using one for any plants.. Besides hydro is too expensive.

[@BasiePlants]

Yeah, I don't think it is a necessity at all unless the conditions are SUPER dry. But there are so many sp to choose from, I hardly think it will ever be an issue :)

[@Fruitsred571]

Do you have any advice for transitioning hoyas out of super humid prop boxes into room humidity? I’ve had a number that root lovely in the prop box and then shrivel up once I move them out even when I keep close attention to the soil and light (so I’m assuming the humidity change is the culprit)?

[@megusina2794]

Hello from Madrid. Since May or so I have my Hoyas on a west facing terrace. It has sun all afternoon so the temperature is very high and the humidity very, very low (below 20% some days). It is glazing with @Lumon system so I keep some of the panels open to let the air flow so Hoyas are almost like outdoors. At the moment, they seem to appreciate it. Depending on the species I have them in the shade with lots of light or some filtered direct sun. I spray them a couple of times a day, especially at sunset so they can cool down a bit. In winter the temperature drops quite a lot (6ºC min) so this next winter I will have to keep the new Hoyas indoors (I still don't know how or where I am going to place them). In case it helps anyone, the species that I have always kept in the terrace winter and summer with no issues are carnosa (standard and krimson princess), mathilde, stoneana and pubicalyx. Some of the new ones that seem to be thriving this summer on the terrace: obovata, sigillatis, rosita, linearis, aff burtoniae variegata (the one under some filtered sun), australis lisa, illagiorum, benguetensis (growing like crazy), cummingiana, some krohnianas and lacunosas, NGG, NS12-323, sunrise and globulosa. Caudata from sumatra got quite dehydrated so I had to protect it indoors a few days ago. With other new Hoyas since last fall, I have not tried outdoors (callistophylla, gnung gading, crassipetiolata splash, rotundiflora, polyneura splash, cutis-porcelana...). Sorry for the extension, I hope it will be useful to someone.

[@BasiePlants]

That is one thing I forgot to mentiong but it does work - spraying does help them cool down :) Wow, 6 degrees is quite low! I am interested to hear what hoyas can withstand that! :) And I am sure people would appreciate that info as well. I would be careful with sigillatis in low temps, just a heads up :) The rest I think might do well :) I think polyneura, rotundiflora, crassipetiolata will do well outside :) I find cutis-porcelana to be very resilient, but some people don't think so :)

[@megusina2794]

At 6 ° C (even less some occasional winter) thrive without problem for years: carnosa (standard and krimson princess) and pubicalyx. Any issues with stoneana and mathilde at 8-9ºC 💪🏻 I learned my lesson with sigillatis, it died last winter outside and I also lost the caudata from sumatra 😭(I bought both back :) ). Next winter I wanted to try linearis and polyneura (fingers crossed) but I will try also the ones you mention, thanks! (I don't have room indoors! 😣 )

[@sandiesorchids9387]

Miro. I have Hoya NS05-055. I've been reading about and I see it's a clone of Hoya anulata fka pseudolittoralis. Does that mean NS05-055 IS anulata? I've seen pictures of anulata and mine sunstresses like anulata and the leaves are the same shape. What is the difference? I want my plant labeled correctly.

[@BasiePlants]

From what I know, it is a clone of Hoya anulata, meaning it is the same species, but a particular clone with collection info. However, I don't know much more than that as I don't grow this Hoya so I haven't looked far into it. :)
