When do amaryllis bloom outdoors

In addition to the garden, you may also grow your amaryllis in containers with adequate drainage holes. A shallow depth is suitable, as these plants like to be somewhat root bound. Provide a snug fit with a standard pot that has a diameter that allows for only one to two inches of space around the bulb. Fill the container with a well-draining potting medium to a height that is one inch below the rim, to allow room for watering.

Place it in a full sun to part shade location, and water only when the soil is dry to an inch down. Those in cooler climes who put indoor winter-blooming potted bulbs outdoors for the summer — or are growing these plants as annuals — need to take them inside again before the first frost. Cut off any remaining foliage to a height of about an inch, and bring container-grown plants back indoors.

Do this before the first frost in cold regions. Before returning a pot to the house, apply neem oil, a natural fungicide and pesticide, and allow time for the entire container to dry before bringing it inside. Alternatively, dig the bulb up, discard the old potting soil, and keep it loose, or repot it in a fresh sterile medium. For plants growing in the garden, you can dig them up, clean off the soil, and either pot them up in sterile medium, or store them loose during dormancy.

Loose bulbs can be gently washed, dried, and stored in a cardboard box. Alternatively, you can plant them out in the garden after all risk of frost has passed. While a bulb by nature contains the food needed to nourish the plant that emerges from it, after the first bloom, it loses vigor. To give it a nutrient boost, apply a well-balanced, slow-release fertilizer in late winter, like you did when you first planted.

Take care to avoid products with excessive amounts of nitrogen, or you may have too much foliage and too few blossoms. Late winter is also the time to begin to water the soil around your bulbs. Keep it moist, but not soggy, until you see the first green sprout. Thereafter, water sparingly. Before the growing season gets underway, remove and replace old mulch. After a year, it deteriorates from a nutritional standpoint, becomes compacted, and may harbor pests and disease.

Amaryllis is phototropic, so staking may be required for the flower stalks. If you do this, be careful not to pierce or damage the bulbs.

As the growing season draws to a close in late summer, and the foliage has withered, remove it from the garden or container, as the debris may harbor pests and disease. Late summer to early fall is the time to divide large clumps as desired, by digging bulbs up and separating large offsets from the mother to relocate elsewhere. Flowers boast centers of deep red that gradually shade to coral and perch majestically atop to inch stems in groups of four to six.

Velvety, burgundy-red petals are sure to stop the show when four to five richly-hued blooms burst into life atop to inch stems.

When growing outdoors, keep the garden beds or containers free of weeds that may attract disease-carrying insects that nest in and feed on foliage.

For minor infestations of sap-sucking pests like aphids , mealybugs , spider mites , and thrips , you may be able to rinse them off the foliage with a steady stream of water. In the case of a large-scale infestation, you might need to apply an insecticidal soap or neem oil. Fungus gnat larvae feed below the soil and cause foliar deformity. Neem oil is the solution here as well, and it can head off diseases spread by young nymphs, such as wilt and blight.

Another sub-surface pest is the root-knot nematode Meloidogyne spp. Learn how to control an infestation of root-knot nematodes in our guide. Slugs and snails turn up when the soil or potting medium is oversaturated. Avoid overwatering and trap them as needed. The amaryllis borer is a caterpillar that may have a feast both above and below ground. Hand pick it, introduce a caterpillar predator to the garden, or apply neem oil to get rid of this pest. And finally, grasshoppers may move into the garden to feast on foliage, especially if there are tall weeds nearby.

The lubber variety is fond of amaryllis. Hand pick if possible, or for large infestations, apply Bt, a biological treatment , or a pyrethroid insecticide. Common diseases include red blotch and soft bulb rot.

Red blotch appears as rusty patches on foliage that often progress to the point of plant collapse. With proper sunlight and watering, it can be avoided. Commercial growers sometimes apply fungicide or soak affected bulbs in warm water for 30 minutes, but efforts are often futile. Your amaryllis should then bloom again next spring.
