White African Iris

Sunlight

Place your iris where it gets at least three hours of direct sun daily. Full sun is ideal, but some shade works too.

Soil

Use soil that drains well and has a bit of sand. If your soil has too much clay, add compost or peat moss to help.

Watering

Keep the soil damp, especially in the first year to help the roots grow. Once grown, the iris can handle dry times but may need extra water when it's very dry.

Fertilizing

Feed your plant with a general-purpose fertilizer in early spring and again in mid-summer for best growth and blooms.

Pruning

After the flowers peak in summer, trim off old blooms to help new ones grow. Remove dead or hurt leaves to keep the plant strong.

Dividing

Cut the groups of plants every 2-3 years in fall. This stops crowding and helps flowers grow well. It keeps plants healthy and blooming.

Winter Care

In cold areas where it can't stay outside in winter, bring the plant inside or treat it as a yearly plant.

When It Arrives

Right after you plant it, give your iris lots of water. This helps settle the soil and gets rid of any air pockets.

During the First Year

Keep the soil wet during the first year. Give deep water once a week or more in hot, dry times. Deep but rare watering helps roots grow deep. Before you water, stick your finger an inch into the soil. If dry, water the plant.

After the First Year

Once it's settled, the White African Iris needs less water. Water it when the top two inches of soil are dry. This might be every two weeks, based on your weather. In long dry periods, keep an eye on it and water to keep the soil from being too dry.

General Tips

Make sure the soil drains well to stop root rot. Water in the morning if you can. This helps the leaves dry by day’s end, lowering the risk of disease.

When It Arrives

After you plant your iris, wait two to four weeks before adding fertilizer. Let the plant settle first, to avoid burning tender roots with chemicals.

During the First Year

In early spring, feed your iris with a balanced, slow-release fertilizer for flowers. Follow the package for the right amount. Fertilize again in mid-summer to keep the plant strong and blooming.

After the First Year

Fertilize your iris at the start of each growing season. This keeps the soil rich and the plants healthy. If your iris looks weak or doesn’t bloom well, do a soil test. Use the test results to adjust your fertilization.

General Tips

Place the fertilizer near the plant's base, not on the leaves or stems, to prevent burn. Lightly water after so nutrients reach the roots. For organic gardens, use compost or a balanced organic fertilizer rather than synthetic ones.

What You'll Need

Sharp, clean pruning shears or scissors. Disinfectant for cleaning the tools (e.g., rubbing alcohol)

Steps for Pruning

The best time to prune your White African Iris is after its peak blooming period in late summer or early fall. This helps you clear dead blooms and ready the plant for next year. Wipe your shears with alcohol to kill germs. Cut away old flowers to boost new growth. Snip flower stems near the leaves. Cut yellow, brown, or damaged leaves at the base to help the plant and let air flow. We suggest thinning it out if your plant is too bushy or wide. Cut some outer leaves and stems at their base. This keeps the plant neat and tidy. After pruning, clean up all the cut leaves and stalks to keep pests away and stop disease.

After Pruning Care

Water your plant well after pruning to help it heal and settle the soil around its roots.
