Q. My peach tree produces copious
amounts of fruit but they have a bitter taste year after year. What can be done
to sweeten the fruit?

| Genetic dwarf or “Miniature” peach. These are NOT called semi-dwarf but are true genetic dwarf. They stay very small and commercial growers thought genetic dwarf trees would revolutionize the peach industry. They didn’t. The fruit quality was not nearly as good as they hoped. They are popular in home landscapes due to their size. |
A. This is a problem with
the variety of peach you selected. Variety names are names like ‘Bonanza’ dwarf
peach, ‘Elberta’ peach, ‘FlordaPrince’ peach or ‘MidPride’ peach. There is
nothing you can do to the tree or the soil to improve fruit quality. If you are
not happy with the quality of the fruit after 3 or 4 seasons, replace the tree.

| One of the Elberta type peaches. Popular in the desert as well as the humid eastern states. |
If yours is a miniature peach, like ‘Bonanza’, a genetic
dwarf tree, then this could be the root of the problem. Genetic dwarf or
miniature peaches were never accepted by the commercial peach industry because
of fruit quality.

| Donut peaches like this ‘Stark Saturn’ are a novelty peach in both yellow and subacide white flesh and very high sugar content when allowed to ripen on the tree. Performs very well in the desert with high sugar content. |
Some years the quality of the fruit produced is better than
other years but generally the fruit quality is subpar when compared to
varieties of fruit grown on standard-sized trees such as ‘Elberta’ or
‘MidPride’.

| A favorite peach of mine because of its shocking red flowers in the spring and very good fruit flavor in the desert. |
Choose a peach by its varietal name and find out what
varieties are good ones for our desert climate. The variety of the peach is
extremely important for good fruit quality. Some of these varieties are marketed
as “semi-dwarf” because of their grafted rootstock. The quality of the fruit is
still good regardless of the rootstock but stick with a reliable varietal name.

| Another personal favorite, an old timer, Indian Blood peach. A subacid peach with wonderful floral qualities, delicious fruit and shocking red flesh when left on the tree to ripen. |
Fruit quality varies with variety and climate where it’s
grown. Fruit tree varieties that taste delicious in Georgia may not have the
same quality when grown in the Mojave Desert. This is also true vice versa.

| Another favorite and not because of its flavor but because it is so early. Hard to find a peach producing fruit in May, even before most apricots. But ‘Earlitreat’ variety does. Along with FlordaPrince and FlordaKing. Solid early producers for the desert with good flavor. |
In hot climates, the
usual problem is a lack of flavor because of low acidity even though the sugar
content can be very high. Sugar only tastes sweet. The balance of different
acids is what gives a peach flavor. I would replace this tree with a variety
that has a history of good flavor in our climate.
