The Tempe Garden Club
Welcome, please have a look around and let us know what you think of our place. We hope you enjoy visiting often. We love to promote gardening and civic and environmental responsibility. If you share that interest, we hope you will consider becoming a member.
Thank you and Happy Gardening!
Here at Tempe Garden Club, we are fortunate to have Lola White as a member. Lola spearheaded the initiative to have the Two-Tailed Swallowtail Butterfly elected as the official Arizona State Butterfly with the passage of HB 2247 on May 9, 2001.
The current mission of Butterfly Quest is to provide an online resource of butterfly (lepidopterra) information available to the public. By visiting the website www.ButterflyQuest.net you have access to a comprehensive educational program free of charge. Please take a minute and explore the fascinating world of butterflies.

HOW TO GROW IRIS
When to Plant For best results, in areas with hot summers and mild winters September or October planting is preferred. It’s imperative that roots of newly planted Iris be well established before the growing season ends.
Where to Plant Iris need at least a half day of sun. In extremely hot climate some shade is beneficial, but in most climates Iris do best in full sun. Be sure to provide your Iris good drainage, planting either on a slope or a raised bed.
Soil Preparation Iris will thrive in most well drained garden soil. If your soil is heavy, coarse sand or humus may be added to improve drainage. Gypsum is an excellent soil conditioner that can improve most clay soils. The ideal pH is 6.8(slightly acidic), but Iris are tolerant in this regard. To adjust the pH of your soil, lime may be added to acidic soils or sulfur to alkaline soils. It is always best to have your soil analyzed before taking corrective measures.
Depth to Plant Iris should be planted so the tops of the rhizomes are exposed and the roots are spread out facing downward in the soil. In very light soils or in extremely hot climates, covering the rhizome with 1 inch of soil may be desirable. Firm the soil around each rhizome and then water to help settle the soil. A common mistake is to plant Iris too deeply.
Distance Apart Iris are generally planted 12 to 24 inches apart. Close planting gives an immediate effect, but closely planted Iris will need to be thinned often.
Watering Newly set plants need moisture to help their root systems become established. Keep in mind that deep watering (at least 6 inches) at long intervals is better than more frequent shallow watering. Once established, Iris normally don’t need to be watered except in arid areas. Overwatering is a common error.
Fertilization Specific fertilizer recommendations depend on your soil type, but bone meal, superphosphate or 6-10-10 are all effective. A light application in the early spring and a second light application about a month after bloom will reward you with good growth and blooms. Avoid using anything high in nitrogen, as it encourages rot problems.
Thinning old clumps Iris need to be thinned or divided before they become overcrowded, generally every 3-4 years. If Iris are allowed to become too crowded the bloom will suffer, some varieties may crowd others out and disease problems may be aggravated. Old clumps may be thinned by removing the old divisions at the centers of the clumps and leaving new growth in the ground. Or you may dig up the entire clump and remove and replant the large new rhizomes.
General Garden Care Keep your Iris beds clean and free of weeds and debris, allowing the tops of the rhizomes to bask in the sun. Bloom stems should be cut off close to the ground after blooming. Healthy green leaves should be left undisturbed, but diseased or brown leaves should be removed.
