Mexican papaya in container
Q. I saved some papaya seeds last year and planted three of them in the spring. To my surprise all three began to grow. It’s hard to tell but the three plants are different sizes. I’d like to transplant them into individual 15 gallon pots. I read where they do not like to be disturbed once they start growing. What might be the right time to attempt that? Meanwhile I need to keep them somewhere once it gets cold outside. What would be the best way to keep them through the winter? And what are the chances they would ever bear fruit some day?
A. Master Gardeners who attend my classes are very familiar with me saying, “You can grow any plant in the world in Las Vegas. It depends on how much time, energy and money you want to use to make it happen.” Rare fruit growers in Phoenix grow papayas outside with some freeze protection applied during the coldest part of the winter. We are not Phoenix but we do have some similarities.
This is what you need to know about papayas to be successful. Papayas prefer rich, tropical, acidic soils. They will not withstand temperatures much below 32F or freezing. Papayas do not like direct sunlight from the late afternoon sun and would prefer about 30% shade if in full sun. Papayas will die growing in soils that do not drain easily but also do not tolerate dry soils.
They are heavy feeders and so require continual applications of small amounts of fertilizer. They need both male and female flowers to set fruit. Sometimes this happens on a single plant and other times it requires a male and female plant. So plant several so that your chances of getting male flowers is increased.
They are normally started from seed and, as you found out, the seed germinates easily. Most of our papayas come from Mexico due to costs of production. They should transplant fairly easily into 15 gallon containers if you are careful and stake it in the new container to keep it upright and wind resistant.
Keep them lightly shaded until the roots have reestablished in the container, maybe one month. They should be able to handle more sunlight after this. Some varieties of these plants may become damaged anytime the temperature reaches about 45° F, others are more resistant to this type of chilling injury. They will not handle any freezing temperatures at all and they become stunted at temperatures even slightly above this.

I have no experience growing them here but it’s reasonable to assume that they would handle morning to mid afternoon sunlight but not late afternoon. They will handle some light shade but will probably not do well in fruiting if the shade is too much.
These trees produce at a very young age, some produce at a younger age than others but they are also very short lived. Of course it would be best if they were in a greenhouse here and handled as a tropical plant.
No one is certain how the fruit is set; whether it is by wind or by pollinators. If you’re lucky enough to keep it long enough to get flowers you may have to do some hand pollination if you do not get fruit set. Your biggest challenge will be to keep it from getting hurt during the winter and still provide enough light during the summer to encourage flowering and fruit set.
