I grow mine under a T-5 light, 16 hours a day with high relative humidity, so I keep mine on the very dry side. I usually water about once every 3-4 weeks, and even then I am very cautious and look the entire specimen over before I water.

How big is your mac and what growing conditions do you keep it in?

It is in a 5" pot and I'll see if I can take a picture.

Every 3-4 weeks?

Hm, that's not very often! I water mine as soon as it starts to dry out, just like most of my other Hoyas. Not even in the dead of winter does it take that long. Of course, TG, you do say you're growing in high humidity. Maybe that makes a difference. Mine just grow in the regular humidity you would find in any home... I don't run humidifiers or make any efforts to raise the humidity around my plants.

Yeah I think the relative humidity in my little grow room is pushing 70%, plus I mist twice a day. When I do water I soak the bananas out of them, and I do use soil in my mix so I gotta be real careful about watering.

But OP this is about you! Where did you go and how does your Hoya grow?

I generally water my hoyas in the four and five inch pots once a week. The larger hanging basket plants less often. I do water my Multiflora twice a week and my Lacunosa too but the second watering is just plain water.

I add one quarter teaspoon per gallon of dyna-gro each week for three weeks and Neptune fish and kelp fertilizer for the fourth weeks watering.

The smaller pots are in a southwest facing window and the hanging baskets in an east facing window.

I have the humidifier set for 55% humidity and a fan to circulate the air.

I just got the Macrophylla a week ago and the seller said to let it dry before watering but Joni, at SRQ said it needs more water than other hoyas which is confusing.

Please let me know if you need more information.

Thanks!

I have a very large variegated macrophylla and a smaller all green,I recieved from Denise several years ago. Both live and thrive in a northeast window and kept evenly moist. The room is warm, 76 degrees with a slight night temperature drop and humidity 70/75% and I also have ceiling fans. My plants do not seem to go dormant and I do fertilize lightly each time I water. For my location, North Texas, this seems to work although I started out keeping them on the dry side. The variegated plant which is about 10 yrs. old bloomed for me this summer.
