General1
|
|
|
The period from March through
September is generally the best time to apply granular mixes containing
nitrogen-phosphate-potash-magnesium (N-P-K-Mg). |
|
|
|
|
Nutritional sprays2
|
|
|
Apply 2 to 4 nutritional sprays to the leaves
anytime from March through October. Sprays should contain magnesium,
manganese, zinc, molybdenum, and boron. Follow dilution directions on
the label.
|
|
|
| Iron applications |
|
|
|
The period from April through September-October is
generally the most effective time to apply 2 to 4 soil drenches of
chelated iron material to high pH, calcareous soils or to apply 2 to 4
soil applications of iron sulfate to acid, sandy soils.
|
|
|
| Watering |
Water trees during after periods of 5 to 7 days or
more. Watering during the summer may be unnecessary unless drought
conditions prevail. Water less during the winter months (November to
February).
|
| Insect control |
Monitor the tree for insect infestations year
round. Have the insects identified first and contact your local
Cooperative Extension Agent for recommended control.
|
| Disease control |
|
|
|
|
Monitor trees exposed to excessively wet soil
conditions for signs of root rot: wilting, leaf yellowing, leaf drop,
and stem dieback. Contact your local Cooperative Extension Agent for
recommended control.
|
|
|
| Pruning |
|
|
|
Selectively prune bearing trees during the warmer
time of the year to reduce tree height and if necessary, spread of the
tree canopy. This should be done annually.
|
|
|
|
|
|
1, Examples of dry fertilizer materials include
6-6-6-2, 8-3-9-3, and 4-2-12-2 (N-P-K-Mg).
2, A spreader-sticker may be added to the
nutritional spray to help prevent washing off due to rainfall.
