Brown spots on Hoya

Troy’s leaves are looking a little brown and spotty lately. I removed a few but now more have been going limp and brown. Any tips? #HoyaHangout #Hoya
1ft to light, indirect
4” pot with drainage

If a hoya plant has brown spots or specks on it, it is most likely a result of overwatering or under-watering. Most of the time, brown spots appear due to overwatering, as these plants require only a limited amount of water to thrive. So when they receive an excess of water, it leads to root rot, which causes the plant to slowly wither and die if left unchecked.

Root rot is when the plant receives too much water or if the water is stagnant inside the pot due to the lack of a drainage hole. Root rot in plants eventually leads to root loss, which can slowly kill the plant.


On the other hand, the plant can also wither if it receives little to no water for a long period of time. This will result in the drying up of leaves, which usually begins with brown spots appearing on all the leaves.



In both cases, brown spots usually indicate a deficiency or excess of hydration and can lead to the drying up of the entire plant if it is not dealt with immediately.

How to Cure
Make sure you do not overwater the plant, especially if the plant is kept indoors where it does not receive direct sunlight.
Reduce the amount of water during winter or rainy seasons.
Water the plant only once a week during summer and spring.
Make sure the plant has a drainage hole so excess water can escape.
Conduct a touch test of the soil if you are unsure about watering the plant.
If the soil is hard and dry, and if the leaves look lifeless and withered, water the plant immediately and closely monitor it for the following weeks.
If root rot has already taken place, transplant the plant after getting rid of the rotted roots.


How to Prevent
Brown spots on hoya plants can be avoided by making sure the plant receives the right amount of water. Do not over or under water hoya plants, as both can result in the eventual death of the plant.

Water it once a week during hot seasons and once in two weeks during winter, after checking the moisture content of the soil with the help of a touch test
Following for tips myself, have one that looks just like this 😬
@HoyaAddict Jasmine- any advice you give to help a browning Hoya turn green again?
This looks maybe a bacterial infection @HoyaAddict ? I'm not too familiar with Hoyas.
Good luck with it to both of you! πŸ«ΆπŸ’š
@HoyaAddict this is so detailed! thanks so much for sharing your knowledge with us!! πŸ₯°
@HoyaAddict Thank you! I’m worried it’s root rot, I have been watering less than once a week (every 10 days or so, definitely dry soil when I do) so I feel like I haven’t been overwatering but I’ll check out the roots and do some pruning. 🀞
@samsquantch I agree πŸ’― with @HoyaAddict
I just repotted and the roots honestly looked in good shape (white, not wet/rotting), but they are small and I read that Hoyas like to be more crowded in their pot, so I’m using a smaller pot in terracotta, and more coco coir based potting mix and lots of drainage. 🀞
@samsquantch If the roots look good and your putting in a smaller pot then you may need to water more. Check if your leaves feel soft/bendy or for wrinkles and you’ll know if you need to water more 🫢
