To Grow Beautiful Iris Plants
in 8 Easy steps
A few important steps
if you are planning to
plant your first Iris Garden, and even some good suggestions
for growing healthier and more beautiful iris for
the seasoned gardener.
Iris is a hardy perennial flower grown for its large, showy
blooms held high above the long, narrow leaves.
You'll see iris
widely distributed throughout the north temperate
zone. Their habitats are considerably varied, ranging from
cold regions into the grassy slopes, meadow- lands, stream
banks and deserts of Europe, the Middle East and northern
Africa, Asia and across North America.
Although iris are hardy plants that
thrive in many areas, following these 8 simple tips will make
yours stand out from those being grown by your neighbors.
1. When to plant. Plant in July, August, and even September. If
your summers are hot and winters mild, start planting in
September and on into October.
2. Where? Select an area with at least a half day of full sun and
good soil drainage. Raised beds or slopes are good spots.
3. Preparing the Soil. Most garden soils will support the growth
of your iris plants. If you are uncertain about the quality of
your soil, have it analyzed. A pH of 6.8 is ideal.
Add coarse sand or humus if your soil is heavy. Your
garden shop will guide you in adjusting the pH (Acidity reading)
4. How Deep? The 'root' (or bulby thing) is called a rhizome.
Plant it just deep enough for its top to show and spread it's
roots out - facing down. In very hot climates, put about an inch
of soil over the top of the rhizome. Tamp the soil around the
rhizomes and water. Don't plant them any deeper than this.
5. How far apart? 12 to 24 inches apart is best in the long term.
Closer planting leads to more frequent thinning but is prettier
in the short term. You choice -
6. About watering - deep watering less often is better than
shallow watering too often. It depends upon your soil and your
climate. Don't over-water. Actually, established iris don't need
to be watered unless your climate is arid.
Fertilizing - depends upon your soil. A light application
of bone meal, superphosphate and 6-10-10 in early spring and
again 3 or 4 weeks after blossoms have withered will bring good
future blooms and growth. Do not fertilize with high nitrogen
8. Thinning the rhizomes - necessary to be done every few
(3 or 4)
years. If you wait too long between dividing the rhizomes, your
iris plants will become overcrowded leading to less desirable
blossoms and possible plant disease. Thin by dividing clumps of
Let your iris
rhizomes have full sunlight and warmth. Cut the flower stems off
close to the ground when the blossoms have withered. Remove any
brown or diseased leaves, but leave the healthy green leaves
And all gardeners know that keeping their gardens free of weeds
and debris is just as much the fun part of this rewarding
pastime as is enjoying the beauty of your iris plants and blossoms.
