Most are also under an overhang, so that the rain falling directly on them is reduced.
One of them places old windows, leaned up against the house, so that any rain falling toward the soil by the tree, will be deflected.
Early blossoming can be an issue. Sometimes the peaches will bloom and they will not be adequately pollinated. Spring rains can also damage the blossoms.

My trees look way worse than yours. Many experienced gardeners just refuse to grow those kind of trees. Others use toxic pesticides and end up eating a few peaches along with their toxic pesticides. Some cover their trees with a tarp from December 1 to March 1 to prevent them from getting peach leaf curl. Growing the tree in a plane, like an espalier is usually required for that. I use compost tea, which has so far been effective in combating the many diseases that peach trees get. I wasn't foolhardy enough to buy a peach tree, but I'm learning through growing a peach tree that grew out of our compost into the yard. So far, lots of work, but good enough.
Peach tree leaf curl: This is a common disease of peach trees. Sprays of horsetail tea, garlic (look further down the page for recipes) and seaweed can help to prevent this problem. Growing chives underneath them also helps. For best results use a mix of fermented horsetail, nettle, and comfrey tea as prevention.
Horsetail Tea (Equisetum arvense): The common horsetail plant, which is very invasive, is rich in silicon and helps plants to resist fungal diseases via increasing their light absorbing capabilities. Use on peach trees to control peach leaf curl. Use on most plants to combat powdery fungi, and on vegetables and roses to control mildew. You can use this on seedlings and plants in closed environments too! Great in greenhouses! Prevents damping off.
INSTRUCTIONS: In a glass or stainless steel pot, mix 1/8 cup of dried leaves in 1 gallon (3.8 Litres) of non-chlorinated water. Bring to a boil, then let simmer for at least 1/2 hr. Cool and strain. Store extra concentrate in a glass container. Will keep for a month. Dilute this mix, adding 5-10 parts of non-chlorinated water to one part concentrate. Spray plants that show any symptoms of fungal type disease once every 4 days. Spray your seed starting mixtures to prevent damping off.
The best soil for pawpaw is a deep, rich, humusy loam with good drainage and a steady moisture supply. Fortunately, pawpaws are adaptable and will tolerate many different soils including heavy clay or sand. They do not tolerate water logged soils, however. Avoid sites where water stands for periods of time. Sandy soils possess good drainage but present problems of low fertility and low moisture holding capacity. The soil acidity should be in the range of pH 5.5 to 7.0.
