Discover 6 Expert Tips for Successfully Cultivating Amaryllis Bulbs


In this article, we will continue to explore the best tips for growing amaryllis. Amaryllis is a beautiful flowering plant that can brighten up any room with its vibrant and non-stop blossoms. Whether you have just purchased your first bulbs or have already grown amaryllis before, this article will provide you with the necessary care and instructions to ensure that your amaryllis thrives.

Tip #1: Select the right bulbs. When purchasing amaryllis bulbs, choose bulbs that are firm and plump. Avoid bulbs that are soft or have any signs of mold or decay. Also, keep in mind that there are different varieties of amaryllis, some of which have different flower colors and patterns. Select bulbs that will bring the desired growth and flowers to your home.

Tip #2: Plant in well-draining soil. Amaryllis prefers a soil mix that is relatively light and well-draining. Use a mix of equal parts of perlite, potting soil, and sand to achieve the right consistency. This will prevent over-watering and ensure that the roots of your amaryllis do not rot.

Tip #3: Give it enough light. Amaryllis loves bright, indirect light. Place your plant near a window where it will receive sunlight, but avoid placing it in direct sunlight, as this can cause the leaves to burn.

Tip #4: Water thoroughly, but don’t over-water. When watering your amaryllis, make sure to thoroughly water the soil until it’s completely moist. Then, allow the soil to dry out between watering. Over-watering can result in root rot, while under-watering can cause the flowers and leaves to fade.

Tip #5: Watch out for toxicity. It’s important to note that amaryllis bulbs and plants are toxic to cats. If you have a cat, make sure to keep your amaryllis out of reach, or consider selecting a different plant that is non-toxic to pets.

Tip #6: Repotting and dormancy. After your amaryllis has finished flowering, you can choose to repot it or simply cut off the flower stalk and let it go into dormancy. If you decide to repot, make sure to use a pot that is slightly larger than the current one. Follow the instructions for repotting to ensure that you are providing the right care for your amaryllis.

By following these six tips, you can enjoy the beauty and long life of amaryllis flowers in your home. Whether you are a beginner or an experienced gardener, these tips will help you care for your amaryllis and keep it blooming year after year.

Growing Amaryllis

One of the most joyous and long-lasting flowers you can grow is the amaryllis. With their fleshy, show-stopping blooms, these plants are sure to brighten up any space.

To start growing amaryllis, select a bulb that is firm and plump, with no signs of disease or rot. Amaryllis bulbs are typically sold in the fall, and they can be planted right away or stored in a cool, dark place until ready for planting.

When planting amaryllis, choose a pot that is only 1-2 inches larger in diameter than the bulb. The pot should have drainage holes to prevent overwatering. Fill the pot with well-draining soil, leaving about one-third of the bulb above the soil line. Firmly press the soil around the bulb and water thoroughly.

Place the potted amaryllis in a bright, sunny window where it will receive at least 6 hours of direct light each day. Keep the soil moist, but not soggy, watering only when the top inch of soil feels dry.

As the amaryllis grows, it may become top-heavy and have a tendency to tip over. To prevent this, you can use stakes or place heavy decorative objects around the pot to provide support.

During the growing season, the amaryllis may produce additional shoots or roots. If there are multiple shoots, you can select the strongest one to remain and remove the others. If there are lots of additional roots, you may need to repot the amaryllis into a larger container.

Once the amaryllis starts blooming, be sure to display it in a place where it can be enjoyed. Amaryllis flowers can last for several weeks, but they will fade over time. To keep the flowers looking their best, remove any faded blooms by gently pulling them from the stem.

After the amaryllis has finished flowering, you can continue to care for it to ensure its long-term health. Cut the flower stalk back to about 1 inch above the bulb and place the plant in a cool, dark location for 8-10 weeks. During this time, reduce watering and stop fertilizing.

After the resting period, bring the amaryllis back into a well-lit area and resume watering. Within a few weeks, new foliage will emerge and the plant will begin its next growth cycle.

It’s important to note that all parts of the amaryllis plant can be toxic if ingested, so be sure to keep it out of reach of children and pets.

With proper care and attention, your amaryllis can continue to bring beauty and joy into your home for many years to come.


One of the key aspects to keep your amaryllis bulbs blooming is to ensure they are potted correctly. The pot you choose should be deep enough to allow for root development and stable enough to keep the top-heavy flowers from toppling over. Amaryllis bulbs are typically sold with their roots dry and dead-looking, so don’t be discouraged by their appearance.

To pot your amaryllis bulbs, begin by selecting a pot that is only an inch or two larger in diameter than the bulb itself. This will allow the plant to focus its energy on flower production rather than root development. The potting mix can be a regular potting soil or a specialized mix for bulbs – either will work fine. Fill the pot about half full with the potting mix, ensuring that the base of the bulb will be above the potting mix.

Carefully place the bulb on top of the potting mix and continue filling the pot with more mix, gently pressing down as you go. Leave the top third of the bulb exposed, as this is where the flower stalk will emerge. Water the newly potted bulb thoroughly, allowing any excess water to drain away.

Now it’s time to find the right spot for your amaryllis. The ideal temperature for amaryllis blooms is between 60 and 70 degrees Fahrenheit (15 to 21 degrees Celsius). If the temperature is too cool, the flowers may take longer to appear and the stalks may grow taller and less sturdy. If the temperature is too warm, the flowers may appear quickly but the blooms may not last as long. Make sure to keep your amaryllis away from drafts and heating vents to maintain a consistent temperature.

Amaryllis bulbs also require a good amount of bright, indirect light to thrive. Place the potted bulb in a location where it will receive several hours of light each day, but avoid direct sunlight. Too much sun can cause the leaves to burn and the flowers to fade quickly. If you notice the leaves of your amaryllis leaning towards the light source, simply rotate the pot every few days to ensure even growth.

Fertilizing your amaryllis plants is essential for lasting blooms. Use a well-balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Start fertilizing your bulbs when the first shoots appear and continue every 2-4 weeks until the leaves begin to die back. Follow the instructions on the fertilizer package for the correct dosage and application method.

Once your amaryllis has finished blooming, you can cut back the flower stalks to just above the base of the bulb. This will prevent the plant from wasting energy on seed production and encourage it to focus on building up energy for the next blooming cycle. Some varieties may produce additional blooms, while others will require a dormant period before flowering again. To ensure a period of dormancy, store your amaryllis in a cool (55-65 degrees Fahrenheit or 13-18 degrees Celsius), dark place for 8-10 weeks. During this time, reduce watering and cease fertilizing. After the dormant period, you can bring your amaryllis out of storage and resume regular care to encourage it to bloom once again.


Watering is an important aspect of caring for amaryllis plants. Here are some tips to ensure your amaryllis gets just the right amount of water:

  1. When you first plant your amaryllis bulb, water it thoroughly to help settle the soil.
  2. After planting, wait until the top inch of soil feels dry before watering again.
  3. Be careful not to overwater the amaryllis, as too much moisture can cause the bulb to rot.
  4. Water the plant at the base, avoiding getting water on the leaves and flowers.
  5. During the blooming period, water the amaryllis more frequently to keep the soil evenly moist.
  6. As the blooms fade and the plant enters its dormancy period, reduce watering to allow the bulb to rest.

An easy way to determine if your amaryllis needs water is to stick your finger about an inch into the soil. If it feels dry, it’s time to water. If it still feels moist, wait a bit longer before watering.

Remember to select a well-draining potting soil and ensure your pot has drainage holes at the bottom to prevent water from sitting in the base.

While fertilizing is not necessary during the blooming stage, you can use a liquid fertilizer following the instructions on the package to encourage healthy growth during the rest of the year.

By following these watering tips, you can ensure your amaryllis plants receive the right amount of water and continue to produce large, wonderfully blooming flowers.
