Light: Shamrock Plants need bright indirect light to grow well and produce flowers. They can often bloom all winter if kept in a sunny spot.

Water: Keep the soil of a Shamrock Plant barely moist but never soggy; allow the top 2” of soil to dry out before watering. It’s best to water a Shamrock Plant from the bottom so that the thin fragile stems of the plant don’t get water logged and the soil stays loose.

fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small.  : Feed a Shamrock Plant monthly in the spring and summer when it is actively growing with a basic houseplant food at ½ the recommended strength. Never feed a Shamrock Plant when it is dormant and the bulbs are resting.

Temperature: Shamrock Plants grow best in cool temperatures between 60-70 degrees during the day and 55-65 degrees at night.Flowering
