Below is my report for 2018 Peaches:
We just completed year 6 of our peach growing experiment with more fruit than we had ever seen as a result of no frost damage. My climate produces excellent peaches, but frost damage normally reduces potential yield. So far we have produced few or no peaches in about 1 out of 4 years. Thinning is normally easy but this year we under thinned by a large amount even after raking a 5 foot PVC pipe over the branches and several hand thinnings. We normally use a baseball bat for first thinning if we have a huge fruit set, but we actually had to rake the limbs to reduce the number of peaches this year. Some of the early varieties produced fruit almost too small to sell due to the lack of thinning, but later varieties produced normal size fruit. Fruit quality was good except for the last picking on Flame Prince which received 9 inches of rain over about 10 days followed by several more inches just before picking. These peaches rotted from the inside although they showed no visible defects. Red Haven, Fire Prince, Winblo and Contender yield lots of sweet, juicy peaches and their picking dates overlap some. Better varieties exist in some ripening windows, but were not available when I planted the orchard.
Rich May – Over production made a lot of small peaches but of good quality with nice sweet acid balance. The unpruned trees did not produce any sellable size fruit. This variety is sometimes impacted by frost. Size is good with good thinning.
Carored – Better size with good quality
Ruby Prince – Lots of small fruit and split pits. My least favorite peach over past several years.
Gala – Year 3 produced good crop of tasty peaches. Fills gap before Red Haven
Red Haven – Excellent peach with good yield. Freestone when completely ripe
Fire Prince – Another excellent peach with good yield
Winblo – Probably my best peach - always in demand
Contenter – Excellent high chill hour peach. My most reliable peach
Sun Prince – Year 3 produced good crop but ripeness difficult to judge.
Flame Prince – Excellent yield and good peach but some internal rot problems. Last picking around 8/30
