5 Best Fertilizers for Growing Amaryllis – A Buyers Guide

5 Best Fertilizers for Growing Amaryllis –  A Buyers Guide

The Amaryllis is one of the most good-looking plants that produce stunning flowers. It hails from the plant genus Hippeastrum and makes an excellent indoor as well as outdoor plant.

The genus has 70 to 75 species and over 600 hybrid cultivars.

The Amaryllis plant is tropical in nature and showcases large bulbs that attract the attention of any and all by-passers. It originates from the Amaryllis plant family, which includes over 60 genera.

It was first sighted in South America along with its fellow species such as the Naked Lady. Its strap-like thin leaves that emerge from the ground level set it apart from the Naked Lady variety with no apparent foliage.

The Amaryllis flowers form in an upward fashion from their center and are nearly equal to the attached stalks. It reaches a height of about 18 to 36 inches (46 to 91 centimeters); however, it mostly depends on the variety and the environment.

The beautiful plant produces large lily-like or bell-shaped flowers that enhance the appearance of the dullest corners. So far, the colors they have been observed in are white, pink, red, salmon, orange, and bicolor.

The Amaryllis plant opens up to present two to six flowers per stalk, even with minimum to normal care. Moreover, the most famous varieties that are frequently sold include the Dutch or South African hybrids that bloom without any special treatment when initially purchased.

For a plant as impressive and hassle-free as the Amaryllis, it deserves the utmost care and love. Some of the main determinants for growing a healthy and happy Amaryllis are moisture, potting soil, and, most importantly, fertilizer.

Fortunately, the gorgeous Amaryllis thrives with the application of a wide variety of fertilizers, and to help you narrow down these types, we have prepared this simple guide.


Planting the Amaryllis Plant

Before feeding your plant, you must first prepare an environment for it that feels like home, or at least is not too different than its natural habitat. Although several hybrid varieties are now available, their basic needs remain the same.

Like most plants, the Amaryllis likes open and fresh air, and thus, it should be planted in well-draining and well-aerated soils. If in a pot, please ensure that it has drainage holes at the bottom for unrestricted drainage.

For people living in USDA hardiness zones 8 to 10, the ground available outdoors is ideal. When the Amaryllis is planted in the soil, it grows reasonably well without causing you much trouble.

Things are almost just as simple for the enthusiastic gardeners living away from these zones as these beauties will thrive even in less than ideal conditions.

To create the perfect soil mix, rub one to two tablespoons of bone meal into the planting hole, which easily fits the entire bulb. With the help of your hands, work the bulb into the planting hole, ensuring that the plant remains upright.

However, keep in mind that the plant’s tip should slightly protrude above the surface of the soil. You can also add a mixture of peat moss and perlite; this makes an excellent growing medium. Furthermore, grow the plant where it receives plenty of sunlight all day (6 to 8 hours) and enough water to keep its soil moist; these settings promote blooming and new growth.

I strongly suggest not to use pine bark in Amaryllis’ soil mix as it may cause complications for the plant.

Nitrogen further encourages healthy food production and helps the plant reach its maximum height.

Next comes phosphorous, which is vital for producing vibrant blooms. It also plays a chief role in numerous key functions including the transfer of energy (food) from one part to another, fair distribution of sugars and starches, passing on of genetic characteristics from parent plant to offspring, and lastly, photosynthesis.

Last but not least is potassium which is a major regulator of photosynthesis and the opening and closing of stomata, the parts that are involved in gaseous and water vapor exchange. Furthermore, it prevents energy losses and reduces unnecessary perspiration.

Additionally, this fertilizer is made up of a slow-release formula, meaning that it gradually releases its nutrients giving the Amaryllis plant plenty of time to take up all minerals efficiently and use or store them, as per the plant’s requirement.

It also encourages beautiful and vibrant blooms that add to the Amaryllis plant’s attractiveness.

Amaryllis Fertilizer Buying Guide

Knowing your plant and its details thoroughly is essential before bringing home a fertilizer. Some plants like all minerals (NPK) in an equal quantity, while others like a greater content of one only.

The latter is the case with most of the flowering species, such as Amaryllis, that need phosphorous in an abundant amount to produce their characteristic blooms.

An ideal fertilizer is one that offers nitrogen, phosphorous, and potassium in the required amount and simultaneously strengthens the plant’s roots.

Most fertilizers that are now available in the market offer all the important minerals and other components to plants.

However, some lack the property of being environment friendly, while others do not contain all the components in the right quantity.

The Pro Organic Lawn Fertilizer by Shin Nong is the one fertilizer that has it all. Its formula is 100% organic and non-toxic to mother nature.

Its amazing features, such as no odor, OMRI recommendation, certified use, and microorganism activity set it apart from other fertilizers.

The composition of the Pro Organic Lawn Fertilizer is also safe for children as well as pets. It does not only improve the plant’s overall growth pattern but also makes the soil more fertile and maintains the optimum pH of 6.5-ideal for the Amaryllis plant.


Benefits of using the right Fertilizer

Adding in the right fertilizer is imperative for the following reasons:


Healthy Development

Once the Amaryllis bulb is planted, it gradually forms foliage; this is the right time to fertilize your plant. Adding feed before you notice foliage can have detrimental effects on the plant, such as toxicity.

You can either choose a slow-release granulated fertilizer or a liquid fertilizer. In both cases, please ensure that you get a fertilizer with the correct NPK ratio; one that is balanced and appropriate.

The slow-release fertilizers are mostly applied every three to four months, while a liquid fertilizer is used more frequently, two to four times a month, with evenly spaced intervals. Establish a proper fertilizer regimen and make sure your plant easily adapts to it.

Moreover, place the plant in its desired level of light. For Amaryllis, full sun is the way to go and ample watering through growing seasons of summer and spring.

You can also follow the instructions mentioned on the packaging for feeding your plant.


Enhanced Blooming

After the dormancy season, bring the Amaryllis plant outdoors, where there is plenty of moisture and sunshine. Allow the older leaves to fall off and help the plant develop newer and healthier foliage.

When you see a good amount of leaves, start fertilizing with a low-nitrogen feed, for instance, a 4-10-10 or 5-10-10.

The low nitrogen content decreases the possibility of nutrient toxicity, and the other components help the plant flourish and bloom.

Phosphorous primarily plays a key role when it comes to blooming and helps the Amaryllis plant form vibrant and bright flowers.


Stronger Immunity

An adult plant with a weak defense system is as vulnerable to disease and infection as a baby plant. Various components of the fertilizer help strengthen the plant’s immune system.

Particularly outdoors, the plant is exposed to various insects and bugs at all times. Adding a fertilizer that protects it against unwanted harmful organisms is essential for optimal growth.



Proper fertilization is the key to maintaining a plant’s health and beauty. This tropical plant has such captivating beauty that it is often presented as a gift to loved ones on occasions such as Christmas.

The best fertilizer for the Amaryllis is one that has all essential components in the right amount, maintains the plant’s soil pH, strengthens its roots, and helps it achieve its greatest potential.

Although its growing seasons are summer and spring, it can flourish all year round and even be enticed to bloom again. All it needs is good quality feed, sunlight, and plenty of love.
