Ordered soursop and bring it in at night if temps are 40 or less. Temps have been 58 to 75 around here during the day. Leaves are turning brown. What should I do to get it thriving? Will it grow better in a greenhouse instead of my home at night? How can I tell if it wi ll bear fruit? I don't have another soursop tree but will it do better around my peach or lemon tree?
As long as you can keep the temperatures from falling below that, any means will do.
The primary reason for having a second tree will be for cross pollination, and for better crop. If the trees are of a different species, then it will not serve this purpose.

I live in South East Queensland and am having the first season of fruit on my 2 trees and all looks good, but there is a lot of small ants on the fruit, is that harmful, also the fruit is appearing on the tree progressively and we are now in autumn am worried if it will ripen as we go towards winter. any help with the caring for this tree will be very much appreciated. if ants are harmful can you tell me how I can get rid of them without harming the fruit. The lowest likely temperature in winter overnight would be not less than about 6 deg celsius and daytime not less than about 14c I hope you can help. Thank you Mario
It would seem that you are right at the edge of where they will survive. They should handle the temperatures as long as it never falls below that very far.
The ant can become a problem, or they can signal an aphid infestation. Either way, getting rid of them is the best option.

I just bought these guanabana trees. Planted them on Monday. Today, 3 days later the leaves did this. I watered one time on Monday, but it the soil was still wet and I didn't want to overdo it.
I would be very concerned with the soil that it was planted into. Immediate infections like this could signify heavily infected soil, pH issues (such as a high pH), or nutrient burns.

I bought regular potting soil and used something called "Rocket Root" that the company who sold the trees sold to me. What is the best method to change the PH of the soil?
I have fertilize, use soil amendments, mulch with grass, fungicide and miticide. I did not apply fungicide and miticide at the same time. Currently, I have added additional soil amendments distance away from the drip root.
This looks quite a bit like nutrient burn. Be sure to test the soil for deficiencies before adding nutrients to make sure that the soil is lacking. Nutrient burn is not easy to correct, and takes quite a bit of time.
On top of that, I notice spots. It resembles the pattern and location of Downy Mildew.

I saved some seeds from a Soursop Fruit and managed to germinate 6 of them! I am ready to plant them but wanted to start them in pots until they were a little older. I germinated them using the paper towel and plastic bag method. They sprouted within the last month and are still small, but ripped through the paper towel. What size pots would be acceptable for them to go in?
Start small, and work your way up. Starting in a 1 gallon pot will be plenty at this time. Each time you repot, once the roots show through the bottom, you will only go up to a container that is an inch or two larger on all sides. You don't want to go too big, too fast.
Here is an article that will help you care for the trees, once you do get them potted up:
