how to maintain heat and humidity for sapodilla and rose apple indoors

[PNWTropical]

I am new to growing tropical fruit trees. This spring I got a Alano Sapodilla and Rose apple (Syzygium jambo) that are in a 7 gallon pot and since growing outside. I am in PNW and brought them inside the house in a small room (plant room) I use for starting seeds and overwinter citrus (Meyer lemons). The plant room temperature ranges between 70F to low 60's F and at around 40% RH. I have had success not killing the lemons for 3 years, putting them under lights for 10 to 12 hrs never had to do anything regards to changing the temperature and humidity lemon trees grow slow during this period.

I have put an oil filled heater (low wattage) and small humidifier with these two additions, I have noticed the temp can be maintained at 70F, humidity between 50-60% (except when I forget to re-fill the water). Is this a good enough situation for my Sapodilla and Rose apple to continue growing or do they need much higher temps and humidity.

That will be good!
Sapodilla and rose apple are pretty hardy.
They can even take periods of below freezing.

Thanks, should I fertilize them during this period. If yes, can I use Dynagro Foliage pro 9-3-6 1/2 dose every other week or is there something specific to tropical fruit trees.

I’ve kept a ton of tropicals including rose apple and sapodilla overwintered in my basement for years. Temps are regularly in the low 60s and I don’t pay any attention to humidity so you should be more than good
