They look super healthy. They like water and to be well fed. Seems you are doing just that. You can tightly pack them, got a few that are stuffed between surinam cherries along the fence line and they are doing fine, producing.
I strongly recommend trying green/unripe papaya when your fruit get larger. Just julienne the skinned papaya, do whatever with the seeds (they are medicinal and also can be used as a spice, probably best when ripe). Marinate the thin papaya strips with lemon/lime/passion fruit, sugar, salt, pepper, and your favorite spices. I like some turmeric and maybe a little hot sauce. BAM! Better than the sweet ripe fruit imo, and you can use it as a side or bed for fish, chicken, or to accompany just about anything. Good by itself.
