Custom seed collection
Cardno can custom-collect specific seed species or genotypes
to meet project requirements. Global positioning system (GPS)
technology may be used as part of the tracking detail provided.
After custom collection, we clean and test the seed to remove inert
material and contaminants, producing a purer and more productive
seed lot.Consult with a Cardno team member
to determine seed
collection and custom growing options.Quality assurance and control
To ensure clients receive the highest quality plants and seed, Cardno
has developed industry-leading standards for grading, cleaning,
testing, labeling seeds, and enhancing plant materials.
Pure Live Seed (PLS) tests
Cardno uses independent laboratories to conduct Pure Live Seed
(PLS) tests to determine the purity and viability for all of our native
seed. This industry measure describes the percentage of a seed
batch that will germinate. A PLS weight of 100% indicates that all
materials are anticipated to germinate. PLS provides a standard
quality assessment to allow customers to compare seed lots,
especially across price variations, of the same species. Based on the
PLS test results, we will increase the bulk quantity shipped to meet
the equivalent of 100% PLS weight.
Plant and seed amplification
When local genotype is important, Cardno can collect plants or seed
from a specific site to make additional plants or seed available.
Amplification is particularly useful for helping to conserve rare plant
species or species with limited availability.
Enhanced root systems
As a standard part of our growing process, Cardno uses a root
maximizer - mycorrhizal fungi - to promote the development of
a vigorous root system for all plants and seed. The symbiotic
relationship between the fungi mix and the roots increases the
plants’ resistance to disease, drought, and insect damage, and it
enhances the roots’ ability to capture nutrients. We apply the same
broad-spectrum inoculants to all seed blends to encourage more
Plant quality grading
Before Cardno ships any plant material, our shipping department
grades each item, using a scale of 1 to 5, with one being the
highest quality. The grading system checks the quality of stems,
foliage, and roots, and looks for any potential diseases or
pests. We automatically ship any grade 1 or 2 plants. Grade 3
plants are shipped if their grade is related to seasonal dormancy
or after consulting with the client. We do not ship any plants
graded 4 or 5.
