Amaryllis: cultivation, maintenance, watering and flowering


With her spectacular bloom, Amaryllis (cultivar) can only be stored in theinterior in our latitudes. Very easy to grow, it blooms again every year without the need for much care. But there is an Amaryllis that can be grown in theoutside, and which is none other than the Amaryllis Belladonne. Let’s find out how to maintain both to enjoy their amazing flowering, indoors and out, over the years.

Growing Indoor Amaryllis (Hippeastrum)

This type of Amaryllis belongs to the genus Hippeastrum and to the family of Liliaceae but, according to the phylogenetic classification, these bulbous plants are integrated into the family of Amaryllidaceae.

Amaryllis needs a lot of light and must be cultivated pot, inside of the dwelling. However, avoid placing it just in front of a window facing due south in order to avoid direct sunlight. We plant our bulb in a substrate of the type potting soil or in peat mixed with a little clay-siliceous soil where it can remain without problem for 3 or 4 years. The bulb should be buried two-thirds, and in a pot of small diameter.

Caring for your indoor Amaryllis

These cultivars don’t need a lot of attention.

Water

One to two moderate watering per week are needed during the growing season. The substrate should begin to dry out between waterings. When the flowers have wilted and the Amaryllis are dormant, they should no longer be watered.

Fertilize

Every two to three weeks, a liquid fertilizer added to irrigation water is welcome after flowering until July. You can use fertilizer for flowering plants. Then, from the beginning of August until October, we fertilize the substrate with a little tomato fertilizer because it is particularly well supplied with potash, in order to promote flowering the following year. We stop the fertilizer application in November.

Repot

Amaryllis (Hippeastrum) must be repotted every 4 years to the maximum. This allows you to replace all of the old substrate. It is therefore not necessary to opt for another larger pot than the previous one. The same is quite suitable.

Parasites and diseases

This plant is not very sensitive. At most, she is affected by the narcissus fly. To prevent the larvae of this parasite from coming to the end of the bulb on which they feed, the best is to resort, in prevention, to a decoction of tansy or even to a maceration of garlic, two natural solutions to spray on the bulb.

Excess moisture may be the cause of gray rot, a fungal disease called botrytis which causes the bulb to wither. As soon as there is the slightest doubt, it is necessary to replant the bulb without delay in a new substrate.

Flowering Amaryllis (Hippeastrum)

It was only if she was able to benefit from a great brightness and one of sufficient sun that this plant can flower. Between November and March The very large flowers of the hybrid Amaryllis bloom, available in different colors and reaching 15 to 16 cm in diameter. A group of 2 to 4 flowers with 6 petals is carried by a hollow stem 90 cm in height at most. The flowers can be heavy enough to tip the pot. It is therefore necessary to take precautions to limit breakage.

As soon as the flowers have wilted, it is advisable to cut the flower stalk about 3 cm above the bulb. On the other hand, we do not prune the green banded leaves that sometimes appear after the flowers. It is absolutely necessary to keep them because they are what will allow the bulb to replenish a stock of nutrients in order to generate the next flowering.

Onne remove leaves only in summer, the beginning of the dormant period, or as soon as they have completely yellowed. It was then that the bulbs have to be stored dry, in their pot, in a cool place with a temperature between 10 and 12 ° C, for a good dozen weeks. After which they will have to be installed at home for a new winter flowering.

You should never throw away an Amaryllis bulb that seems unwilling to form a flower. It will always end up flowering, even if it takes two or three years …

Amaryllis belladonne, to grow outdoors

Also called Jersey lily, this bulbous perennial should not be confused with the Indoor Amaryllis. Moreover, the belladonna is the genuine Amaryllis that botanists distinguish cultivars of the genus Hippeastrum and that we have discussed at length above.

Amaryllis belladonna or belladonna is not a houseplant. It is intended for the garden. It is planted in September, in loose, light soil, and absolutely well drained because the bulb does not support excess humidity. This superb plant must be installed sheltered from the wind and the cold but in a very sunny area of ​​the garden, or partially shaded during the day in the southern regions. It will do wonders with its trumpet-shaped corollas which bloom from the end of August until October 15 or 20.

Note that the Amaryllis Belladonne can be installed in a pot about 35 cm in diameter, which can be placed on the balcony or the terrace, but in any case not at home. Cultivation in pots, on the other hand, provides shelter for the plant if there is a fear of severe frost.
