Amaryllis is popular for being used in flower arrangements apart from the landscapes and gardens so let’s take a closer look at the growth and care of amaryllis.

The planting location

The best soil type for amaryllis is a soil that is loamy, a soil that is rich in organic will provide drainage as well as retain the right amount of moisture.

Avoid soaking the soil when watering your amaryllis because these garden beauties don’t like to sit in water which can lead to rot. Avoid wetting the part of the bulb that is above the ground.

Garden insect pests of amaryllis

Keep an eye out for these listed pests and treat them when spotted.

Spiders Mites

Spider mites are so tiny that they can hardly be seen, their color can either be yellow, green, red, or brown these garden insect pests causes damage by sucking the plant’s sap of fluids. Signs of these mites are spider webbing, the leaves become discolored with brown flecks also. The leaves will also fall from plants that are infested, the use of insecticidal soap or horticultural oil will bring them under control. Before applying insecticides read and follow the manufacture’s direction.


Thrips are tiny insects that can be either red, black, yellow, or dark brown. Thrips can cause serious damage because they have been known to carry viruses along with extracting the plant’s fluids causing leaf drop and failure with flower bloom. To control thrips prune or remove infected plant parts including the flowers. The use of neem oil or insecticidal soap will also eliminate them.


Aphids are pear-shaped and can either be black, red, yellow, green, or brown. Aphids are among the sucking insect group and will cause flowers to drop. These garden insect pests also produce a sticky substance known as honeydew. This honeydew is their excrement that causes sooty mold to form. Applying soapy water or insecticidal soap will bring aphid infestation under control.


Caterpillars are chewing insects that cause damage by eating plant leaves destroying their beauty. Handing picking and dumping them in a bucket of soapy water will bring them under control.

Diseases of amaryllis

Leaf Diseases

This disease which is caused by a fungus shows up as light brown spots surrounded by a yellow or dark brown ring. Leaf diseases will also weaken plants. Treating this disease with a copper base fungicide has proven to give good results.

Red Blotch

This fungus is encouraged by cool damp conditions and causes bright red patches to appear on plant parts, as this disease is allowed to persist the patches enlargens and becomes moist. Because of difficulty in controlling red blotch the amaryllis is drugged up and destroy.

But what is recommended is to soak the bulb in water and 1 percent hydrogen peroxide for about one hour. If the bulb is growing actively replant and treat with a systemic copper-based fungicide. If the bulb is dormant dry and store, then once treatment is completed.

Molds and Mildews

This disease is caused by poor air circulation and environmental conditions, signs include leaves with lesions that are brown which also affect the flower bloom. Gray areas that are moldy will also be seen. The leaves may also develop sooty spots that are black, bring this disease under control by providing proper air-circulation, removing infected plant parts, and reducing moisture.

Mosiac virus shows up as streaks that are light yellow, the leaves which are infected may die. Moist lesions may form alongside the leaves and the flower stalks, there may also be stunting of the flowers. There is no known cure for this disease except to remove and properly dispose of your amaryllis. Aphids are the culprits that spread this disease so controlling aphids will offer help. The use of insecticidal soap or horticultural oil will eliminate aphids

Bulb Diseases

Targets and causes root problems, bulb disease is caused by bulbs that are damaged or soils that are saturated with water. Brown to blackish areas that are slimy also appear, if measures are not taken right away bulbs become soft and begin to decay.

Avoiding damage to your bulbs is so important, give the right amount of water allowing the soil to dry out before giving your amaryllis another drink. Applying a fungicide may also offer help.

3. Install in your garden plant bed.

Pruning Amaryllis

Once the flowers fade remove with a hand pruner when the stalk wilts remove by cutting back where the stalk sprouts from the bulb.

Container grown amaryllis

A great way to grow your amaryllis is from a container, the container that is used should be wider than the diameter of the bulb. The container should also have drain holes for water drainage. A good potting soil that is well-drained is ideal, place a small amount of potting soil inside of the container this is the first layer next place your amaryllis in the center of the container followed by adding more soil.

Allow the upper one half of the bulb to be above ground or the soil’s surface. Gently firm the soil around the bulb and give it a good drink of water. Look for an area that provides anywhere from 70-80 degrees. The soil should dry out somewhat but still retain moisture, once new growth appears, move your bulb to a location that gets lots of sunlight. Every four weeks use a water-soluble fertilizer which will give good results. In about eight weeks flowers should appear.
