The nuisance fruit treatment is a specialized treatment in the early spring before blooming, and fruit productions starts. It is a growth regulator treatment that stops production of nuisance fruit and seeds. In our trials for this treatment, it has proven to be about 90% effective in preventing undesired nuisance fruit.
Common Trees that Produce Nuisance Fruit are as listed:
- Crab Apple
- Apple (if you do not plan to harvest)
- Plum (if you do not plan to harvest)
- Siberian Elm
- Eastern Cottonwood
- Lombardy PoplarLindens
Core aeration is the removal of quarter sized plugs of soil reaching 2-3 inches deep and 4 inches apart. The plugs are used for top dressing are absorbed back into the lawn after a few rainfalls.
Silty clay loam soils in the flood plain areas of the upper Snake River Valley are ideal for aerations in eastern Idaho areas. We recommend aerating annually, in the spring.
Tip #3: Clean up and check any weed trimmers or other equipment that you might have.
“The reduction of a tree’s size using heading cuts that shorten limbs or branches back to a pre-determined crown limit. Topping is not considered an acceptable pruning practice.”
The reason this practice can be referred to as murder is that once it has been done it marks the beginning of the end for that tree. It starts with starvation. If we think of pruning as being a healthy diet for a tree, topping it would equate to starvation. This makes sense because the leaves that make up the trees canopy are the food factories that keep the tree running. When too much of that canopy is removed the trees ability to produce food is also removed. As soon as this happens the tree biologically panics and stimulates a rush of new growth that is often referred to as water sprouts or suckers.
What is a Hobo spider? This spider was introduced to the Pacific Northwest from Europe. It was given a common name “aggressive house spider”, which has now been changed back to its original name. The hobo spider is of importance because of its ability to cause necrotic spider bites similar to those of the brown recluse.
The hobo spider is a member of the funnel-web spider family. They are long-legged, swift-running spiders and they build funnel or tube like webs. The hobo spiders prefer to utilize habitats that have holes, cracks, or other areas which help support their funnel-like webs. Common habitats include rocks retaining walls, crack in soil or concrete, window wells, and in wood stacks. Indoors the hobo spiders can be found in ground-floor levels like basements because hobo’s are poor climbers.
The hobo spiders are most commonly encountered in June through September when the males wander in search for females. Females tend to stay in their webs and are not usually found running about. Males seek for mates from late June to October with most dying before October. The first eggs are laid about mid-September with one to four eggs sacs produced. Cold temperatures eventually terminate the production of eggs by the females.
The eggs hatch in the spring as the temperatures start to warm up. The immature spiders develop for the next year, reaching maturity after the following spring. Males generally have a more toxic bite than the females, while immature seem to cause the most serious bites. The bite of the hobo spider is relatively painless and is reported to fell like a pin prick. If you suspect you have been bitten by an hobo spider, you should seek medical attention immediately.
Many individuals do not like having spiders around their homes so they choose to chemically control them with residual insecticides which should be used to provide a lasting effect. For your safety, Always make sure to read all labels and follow their instruction or hire a professional pest control company.

Conifers will soon be under attack!
Pine and spruce trees are valuable assets to any southeast Idaho’s landscape. They are very adaptable to soils and grow very well here in southeast Idaho. Over the past few years these trees have been plagued by a small invader, pine needle scale. This scale is actually an insect and are easily identified because they are white and found on the needles. In early spring the females lay eggs under their protective wax covering. In our area early summer the eggs hatch and the new generation begin looking for a place to start feeding. When they have a new feeding site established, usually on the new growth of the tree, they “settle” quickly form a new waxy covering that protects them as they feed.
The scale insects feed on the needles of the conifers by sucking plant juices and, because of this, the needles may turn yellow and eventually fall off the tree. If heavy infestation continues, twigs and branches can die.
Young crawlers can be spread by the wind and also transported by birds and other animals. Even if mature trees branches touch, they can crawl over and infest new conifers.
What can you do to help stop the spread of this insect? Early detection and ultimate prevention will limit the extent of the infestation and damaging effects. You can have your trees chemically treated at the correct timing. Use an insecticide to kill the crawlers in the early summer before they have a can create their wax covering. There are studies out that if you also use an insect growth regulator and the insecticide, you can kill both the new and the old scale on the trees.
We have all been feeling the brisk, if not down right freezing, cold mornings around here. While most of our lawns are covered in snow, there are still a couple of lawns with grass peeking out. Try not to walk on your lawn if it is frozen, it can cause damage that will show up sooner than you might think!
The dew that settles in the morning on the grass can be quite beautiful, but when it freezes it puts your grass in a vulnerable state. It is not only frozen on the outside of the blade, but the tissues of the plant are frozen and brittle. When you walk on this brittle grass it causes damage that can not be reversed. Often times you will see the damage with in 12-48 hours in the form of darkening. Eventually the grass will die and turn brown. This can also leave a weakened lawn that may be more susceptible to weed germination.
Now don’t panic if you have been walking on your frozen lawn. The good news is that grass is resilient, and with a good fertilizer and weed control program in place, you can have that thick and lush lawn, even if your lawn took a couple of blows from the winter. Remember though, if you hear a crunch, or see ice on those beautiful blades, try to stay off the lawn!
