QUESTIONS & ANSWERS ABOUT DAYLILIES
Growing daylilies is not a bit complicated, but because we are so
enamored of them that we grow over 670 varieties of them, people
have asked us a number of questions about them. We have noted the
most often asked questions to include here along with the answers.
Q.
How long will a daylily bloom?
A. Each cultivar is different, but the average is about 4 weeks.
We see above average performance each year on some cultivars if
they are established(undisturbed in the ground for two years or
more.). Some cultivars are more prone than others to rebloom giving
another 3-4 weeks of blooms, especially if they receive adequate
water regularly.
Q.
What is a tetraploid?
A. Each cell of a normal plant(a diploid) contains 22 chromosomes
and a tetraploid has 44. For a pollen dabber, this increases the
genetic possibilities many times. Tetraploid daylilies in general
have heavier substance in flowers and foliage and thicker scapes.
Tets are not necessarily better than diploids. There are beautiful
diploids and beautiful tets.
Q.
How often should I water?
A. At least once a week is best. More frequent watering may be
harmful just after planting. One inch of rain a week or the equivalent
in water will give excellent results. However, daylilies can get
by on less water, making them good choices for areas with dry
conditions.
Q.
When is the best time to plant?
A. Since we now have most varieties planted in individual clumps,
we can dig them anytime during the growing season. We quit planting
Oct. 15 in our area so that plants will have 6 weeks growing time
before the ground freezes. There is no best time, though many
daylily growers prefer spring or Aug.-Sept.
Q.
Will my summer or fall planted daylilies grow at all?
A. Yes, and it is normal for the outer leaves on a fan to die
off as the center leaves grow.
Q.
Shall I fertilize?
A. Do not put fertilizer in the planting hole. Top dress in early
spring with a balanced fertilizer or manure.
Q.
Why are some daylilies more expensive than others?
A. A newer cultivar is higher priced than an older one. It is
a matter of supply and demand. Supplies are greater on cultivars
that have been around for a while. Some new introductions of high
quality are priced at $100-$300. The sale of the first few plants
is usually all the monetary reward that a breeder gets for years
of work. A $25 plant is not necessarily better than a $5 one,
though it may be.
Q.
Where can I plant daylilies?
A. Any place with half-day sun to all-day. They fit well in a
border, as facers
Q.
Where can I plant daylilies?
A. Any place with half-day sun to all-day. They fit well in a
border, as facers for shrubs, in underplantings for trees, as
accent plants......the list goes on.
Q.
How much of a plant do I get?
A. We supply a 2-fan division, twice as much as many nurseries
sell.
Q.
When is the best time to visit Garden Perennials to see peak bloom?
A. Most of the daylilies are in bloom July to mid-August with
the last two weeks of July being the peak. There will be daylilies
in bloom from mid-May till frost. Garden Perennials is an official
American Hemerocallis Display Garden.
Rust Report
Rust appears on the foliage as raised orange to yellowish raised
spots. Some have reported just a few spots and others have reported
many of them. Rust-affected foliage may appear anywhere in the range
of acceptable to unsightly. The spores become airborne to spread
to other daylilies. No other plant is affected by Daylily Rust except
for its alternate host, Patrinia. It is not likely to kill a daylily.
We received 4 plants in the spring of 2001 from nurseries that we
later learned had rust. We kept the plants well-isolated from all
of the other daylilies and inspected them daily. On Sept. 14, 2001,
rust was found. We are quite certain that any plants that left our
nursery prior to that date had no chance of carrying rust spores.
A thorough inspection on Sept. 19, 2001, was conducted by plant
pathologists from the Nebr. Dept. of Agriculture of all daylilies
on the premises and no rust was found. We are happy to report that: No rust has occurred at our nursery since
2001. Not much is known about this rust. To learn what is known

We
are happy—NO RUST APPEARED AT OUR NURSERY IN 2002!
