Not much time is left to plant tomatoes
Let’s say this problem is a case of watering extremes. When trees take up too much water and try to store it in the fruits, they split open. Splitting does seem to be worst when the trees do not receive adequate water days before a heavy rain. Also, some varieties, like navels and tangerines, seem to have the problem more than other citrus.
You can help prevent, but not totally stop, citrus splitting by keeping an even soil moisture supply. Most trees need water once or twice a week during hot, dry weather.
This helps the fruits gradually enlarge without toughening and becoming more susceptible to splitting. Also, make sure the trees have adequate fertilizer during the season to supply nutrients that help resist fruit problems.
Several of our ornamental grasses have become droopy and fallen over. Why does this happen, and what should I do?
Seasonal rains, hot weather and maybe a little extra fertilizer have encouraged lots of good growth. Many ornamental grasses become floppy by fall, but this can be part of their beauty. If portions are in the way of movement within the landscape or interfere with other plants, the grasses can be groomed to make them more attractive.
Major pruning of ornamental grasses is usually delayed until February, when they have turned brown. Pruning to within a foot or so of the ground removes the mainly dead portions and can help the plants produce new sturdy shoots that are not so droopy by fall. Also, do keep the plantings moist during the dry times and apply a general landscape fertilizer in March, June and August.
Our 12-year-old oak tree has an infestation of caterpillars. I have been told they won’t cause major damage and spraying is of little value. Is it true: The tree is not in danger?
Caterpillars feasting in otherwise healthy oaks are not likely to cause major decline, but these pests can make the trees look unattractive. Also, droppings from the larva stage of a moth, can stain drives, sidewalks and vehicles. Most companies do not like to spray trees due to possible drift of the pesticide within the neighborhood.
When caterpillars are a major concern, some pest control companies inject trees to get these leaf-feeders under control. You can also apply a systemic insecticide to the soil under the trees following label instructions. Several brands are available at local garden centers that move from the soil through the roots and up to the leaves to control the caterpillars as they feed.
