Grapes have long
been popular in gardens and arbors throughout Texas. About half
of all native species of grapes can be found in the state.
Although grapes can make a great addition to a landscape, you
must carefully consider several factors to choose a variety that
will grow well in your area. These factors include:
- Pierce's Disease (PD) is a
vine killer that is a threat in East and South Texas.
- Black rot affects both the
foliage and the fruit and must be controlled with fungicide
sprays when weather conditions are warm and humid.
- Cotton root rot is a soil
fungal disease that kills vines very quickly. It is abundant
in the alkaline soils of Central and Southwest Texas.
Muscadine grapes prefer acidic
soils and have few limitations. American-type grapes such as
Champanel, Black Spanish and Favorite are resistant to Pierce's
Disease. A few French-American hybrids have some resistance to
black rot and mildew. Vinifera grapes are seriously affected by
Pierce's Disease, black rot, mildew and grape berry moth and are
limited to West and North Texas. Vinifera grapes also require
precise vine training and pruning for top-quality yield.
