Has anyone planted Amaryllis outdoors? When and how should I plant mine? I've heard of them being put outside but don't know how deep to plant them and if they can be left outside permanently.

Hardiness Zone: 8a

Vicky from Jacksonville, NC


Amaryllis is hardy to zone 7b and can be left outdoors year-round as long as it is given adequate mulch in the fall and winter months.

Plant new bulbs in the ground in late September or early October and you'll see flowers in the spring. Bulbs should be planted about 1 ft. apart and just deep enough so that the tips ("noses") stick above the ground.

The soil should be nutrient-rich and well drained. The site should receive plenty of sun with some afternoon shade.


Use a low nitrogen fertilizer and make the first fertilizer application as new growth begins, then repeat the application when the flower stalk is 6 to 8 inches tall. Apply a third application immediately after flowering when the spent flower heads and old flower stems have been removed.

You can plant amaryllis left over from the holidays in the spring. Plant bulbs directly in the ground, pots and all, after first acclimatizing them to the bright outdoor light. Make sure the pots are well drained.

We are in Lexington, NC, and have had amarylis that were transplanted from San Diego in our yard for about 5 years. The blooming is not as prolific as it was in CA, but we do have nice blooms. The bulbs that are planted near the sides of the house do the best, but the ones near the street are still alive, and had more blooms that the previous year.

we planted them about 6 inches deep, from the tops of the bulbs. We haven't done any special mulching etc, and we do have snow most winters, (this year has been the exception)

I haven't been able to determine when to cut the leaves of the amaryllis bulbs outdoors, as I know they produce food for next year's flowers. Does anybody know? I know you cut the flowers after they bloom about 2" above the base. I'm in zone 7. Also, what do you do for grasshoppers eating on them? What is good for brownish spots on the leaves and aphids? Thanks, please help. cmbca5m

I need to know WHEN do you trim off the amaryllis leaves if the amaryllis bulb is left in the ground year round, as mine are. I have been letting them turn completely yellow & letting them fall off naturally, but it is pretty unsightly where I have them planted. I know you cut an amaryllis flower stalk off about two inches from the bottom when you want to put it in a vase, but what about just the flower leaves -- do you have to wait until they wilt & turn yellow before removing them. I'm in zone 7. thanks. Does anybody know?
