Planting Bulbs in the Garden in Fall:
- Plant when you receive the bulbs in fall.
- Success with bulbs depends on good soil preparation. Select a site in full sun to light shade with good drainage where water does not stand on the surface after a rain event. Bulbs thrive in well-drained, moist soils. Mulch the soil to protect the bulbs from the heat of strong summer sun.
- Dig the soil to a depth of at least a few inches deeper than the recommended planting depth. Work in organic matter to improve drainage, and at the same time improve the ability of the soil to retain moisture. A moderate amount of a balanced fertilizer may be incorporated into the soil at this time. Mix the fertilizer into the soil so that it does not come into direct contact with the bulb.
- Dig holes spaced 4-6 inches apart. Plant Iris reticulata bulbs 3 inches deep and other iris bulbs 4-6 inches deep. The general rule of thumb is to plant three times as deep as the bulb’s vertical diameter.
- Plant the flat part of the bulb down and the pointed part up.
- Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water and reduce weeds.
Planting Bare Root Plants in the Garden:
- Select a location in full sun with good rich well drained organic soil.
- Dig a shallow hole 2-4 inches deep and twice as wide as the rhizome.
- Make a small mound in the middle of the planting hole. Place the rhizome on top of the mound and spread the roots on both sides.
- Fill the hole with soil and firmly tamp around the rhizome but only partially cover the rhizome.
- Water very well to fully saturate the roots and the soil.
- Wait until new growth starts to appear before applying a layer of mulch.
- Apply an organic bulb fertilizer when the plants emerge in the spring.
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination.
- Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
- Remove and discard foliage after it dies back.
- Iris is easy to grow in beds and borders. The small spring bulbs also work well in rock gardens. For the best visual impact plant iris in masses.
- Iris makes a fabulous cut flower.
