Plant Health
Walters Gardens, Inc. has made a strong commitment to provide
only the most healthy, vigorous product to our customers. All of
our crops are tested regularly for the most common viruses as
well as additional genus-specific viruses where needed. Our fields
and greenhouses are also regularly scouted for signs of pests
or diseases. In addition to the dedicated efforts of our Growers
and Plant Health Team, we make an effort company-wide to
maintain clean and preventative practices to limit the spread and
introduction of pests, diseases, and viruses.
How to Identify
Virus-Indexed Plants (VIP)
A virus-indexed variety is one that has been tested and deemed
free of the viruses listed (right) up to the point of testing. A bow
tie symbol is located in the key code of each variety that has
been virus-indexed.
Sustainable Production Practice
and Integrated Pest Management
In the Fields
Understanding the vital importance of plant health, we remain
vigilant in preventing problems in our fields. Before a crop is
planted in the field, we make sure our planting stock is clean
and disease-free. We then diversify our plantings so that disease
prone items are never planted in the same place twice. All of
the equipment used to plant and harvest our hosta stock blocks
is sanitized between cultivars. We also scout weekly for weeds,
insect damage, unusual variations in growth, trueness to type, and
overall plant health.
In the Greenhouse
Prevention is key when it comes to pest and disease management
in our greenhouses. We do weekly scouting for any pest, disease, or
nutritional issues and do preventative spraying in regular intervals
to prevent the onset of disease. Our goal is to catch problems at the
earliest stage possible and to target the treatment to the specific
crop before it spreads to other plants. When treatment is needed,
we use beneficial insects or reduced-risk pesticides which target
specific pests rather than using broad spectrum chemicals. We
have not used neonicotinoid containing products on our production
crops since 2014.
Virus Prevention and Index
We take great pride in the attentiveness of our Plant Health and
Greenhouse staff when it comes to identifying and preventing
viruses in our plants. All of our plants are tested on a regular basis
regardless of appearance or history. Because there is always risk of
a crop being exposed to a virus, and more so in a field environment,
we will not give VIP status to a variety if we feel there is too much
risk of infection between testing and shipping. If a variety is prone
to viral infection, extra steps are taken to ensure that our stock and
production lines always start with clean material.
