Yardguard:
Treatments Enhance Natural Systems
Scheduled treatment program
Effective programs help balance natural systems and encourage plant
health.
We monitor and treat only the plants that need help.
We do the scheduling so you don't have to worry.

Licensed, experienced plant health care techs.
Techs. are licensed by the State Dept. of Agriculture.
Field training is done by seasoned professionals and is on-going.
Our three senior techs have logged nearly 100 years experience.
State of the art equipment.
Our trucks have several separate delivery systems so techs can custom
mix according to need.
We provide a sharp looking, clean and safe operation.

Plants
that need help
Yardguard is a program of periodic visits by a licensed plant health
care professional to monitor, identify, and treat landscape pests
and disease. The goal of this program is to encourage plant health
and limit damage.
Organic and synthetic control products are applied as canopy sprays
or systemic soil applications
Cultural problems, such as over-watering, pruning, etc., will be
reported to the customer so they can be corrected.

You don't have to worry
Many years of experience working in the plant health care business
has allowed us to predict the approximate timing of fungal and feeding
pests and effectively treat to prevent or cure the problems.
Treatments to ward off disease from leaf, twig, and needle fungal
diseases (i.e. blossom blights, dogwood anthracnose, apple scab)
are best applied before symptoms arise. In the event that damage
is evident, treatments can stop further spread of disease. Timing
is everything when it comes to disease control.
The pictures below show damage from Apple Scab Fungus
and Cherry Brown Rot.
Timely treatments will prevent this.

Systemic soil applications
The choice of products is made with many things in mind. Human,
pet, wildlife and environmental safety is our first consideration.
We choose products and delivery methods to minimize off target exposure.
We employ the least toxic products available and consider
many things in that choice. A common mistake is to think that organic
products are safer. That all depends on the product and the number
of treatments that need to be made.
It would be unwise to choose, as an example, several canopy sprays of pyrethrins (powerful, non-selective organic pesticides) over one systemic treatment with a synthetic product (Merit) made to the trunk of a tree or injected into the soil at the base of the tree. The application placement would make exposure improbable and, even though this is synthetic, it is a low toxic product carrying the same “Caution” label as the organic insecticide. Pyrethrins are non-selective and broad spectrum, killing everything pest it hits, the good guys along with the bad guys. Repeated applications can wipe out the predators, perpetuating the problem. The cost of repeated applications of the organic product would far outpace the cost of the synthetic treatments. So in this case, and in our opinion, the synthetic product would be the best choice, all things considered.

Topping Hurts Trees
Topping trees is almost always a bad idea. Under the right conditions, the tree would have
one main trunk with three or four sturdy main branches. As is the case with most trees,
it should have been left alone to grow with an occasional light pruning, not the chainsaw massacre approach all too visible in commercial parking strips and private properties
around South Sound.

SuperRoots Bio-Fertilizer
Plant responses are phenomenal!

Healthy soil = Healthy plants
Plant health is directly related to soil health. Healthy soil is
rich in nutrients, organic matter, and beneficial micro-organisms.
Plants thrive when grown in healthy soil. If landscape plantings
are showing signs of stress from lack of nutrients (i.e. lack of
vigor, yellowing foliage), soil treatments supplying nutrients and
beneficial biological organisms are in order.
Bio-fertilizer - A "Full Meal
Deal" for plants
Trees and shrubs need adequate nutrients in their root zones so
they can thrive, not just survive. Click here to learn
more.
Root
rotting fungus
From time to time, we find plants infected with root disease, evidenced
by declining foliage or die-back. This may be the result of stresses
on the plant from over or under watering, compaction, improper pruning,
etc. Our trained techs can easily spot problems and may recommend
lab analysis and/or treatments to prevent further spread of disease.

Cultural
corrections
Installation and cultural problems like planting too deep, improper
placement, poor plant selection, poor soils or poor watering
practices contribute to stress. At times, a correction by the landscape
owner is necessary. There is much that can be done to aid sick plants,
and we can help with good information and treatments. An effective
plant health care program is a cooperative effort between our customer
and our team. Expect satisfying results, and enjoy!
Bio-fertilizer
Plants in natural settings get their nutrients from fallen needles
and leaves that are decomposed by soil organisms recycling their
proteins and carbohydrates back through the feeder roots. Normal
landscape housekeeping removes much of this natural material, leaving
plants without a fertilizer. Construction practices often remove
valuable organic topsoil, leaving no natural fertilizer reserves.
Replenishing these necessary elements can be easily achieved by
apply compost (NOT fresh ground bark as it will rob nutrients from plants as it decomposes), and through root fertilizing. Wolbert's Inc. treats
hundreds of landscapes in both spring and fall to replenish nutrients
with a liquid bio-fertilizer consisting of macro and micro-nutrients
(13 different nutrients in all), and beneficial biological elements
found in natural healthy soils. These complex liquid seasonal blends
are injected under pressure into the soil for uptake by the plant
roots. A grid pattern of injection sites (every 16" or so)
is employed to ensure all roots have access to the bio-fertilizer.
This consistent supply encourages plants to reach their potential,
bringing increased color to leaves and needles, larger and more
colorful blooms, and aggressive feeder root development.

Fungus
We work closely with Dr.Olaf
Ribiero (pictured below) when trees are ailing and need additional
help to recover. He tests for root and soil diseases and sends
us a prescription for treatments. This approach enables us to be
the "nurse" giving the "patient" what they need
to recover. Many times cultural things are the problem, i.e., drainage,
poor planting, water Issues, pruning, grass competition, etc. Dr.
Ribeiro makes recommendations for the correction of these and other
cultural problems as well.
