How to Plant Shamrock Bulbs


The shamrock plant is a flowering bulb that reaches a height of 10 to 12 inches and produces clover-like foliage with rose or pink colored flowers. The plants bloom during the months of June through September and are commonly planted in flower beds and containers or used in borders. Shamrock plants will grow well in USDA growing zones 8 through 10 where there is low risk of cold and frost.

Step 1

Choose an outdoor planting location that has a well-drained soil and full sunlight conditions.

Step 2

Test the soil pH level with a home pH test kit. Shamrock plants prefer a soil that has a pH level of 5.5 to 7.5. Amend the soil with limestone to increase the pH number or ground rock sulfur to lower the pH number. Let the soil rest for two weeks after amending.

Step 3

Work 2 to 4 inches of organic compost into the soil using a tiller. This will increase the nutrient value and moisture retention qualities in the soil.

Step 4

Dig a hole 1 to 2 inches deep. Space the bulbs 3 to 4 inches apart from each other. Add a small amount of bone meal to the bottom of the hole and place the bult in an upright position. Fill the hole with soil and gently pack in place.

Step 5

Place a marker at each planting location to prevent accidentally digging the bulb prior to sprout growth.

Step 6

Water the bulbs to keep the soil moist but not wet. Water growing plants when the soil becomes slightly dry. Do not over water or allow standing water around the plant.

Step 7

Fertilize the plants with a balanced 10-10-10 fertilizer once they are actively growing.
