I'd leave it like it is. Light is no problems, Hippeastrums react to water and temperature. If you'd gave it some soil now, make sure that it's completely dry.

Shiane, make sure it doesn't get too cold in your garage - as long as it doesn't freeze it should be ok. I keep mine bare root in a closet in the garage until I get around to potting them back up in February-ish.

Make sure and check the list, especially Jodi's numerous posts, about the best "stuff" to pot it up in. Potting soils tend to stay too moist for the bulb (also don't bury it up to it's neck). Jodi has described a good "media" that is mostly inorganic, which promotes good drainage. CHECK IT OUT for a happy, healthy bulb!

Thanks all your great suggestions. This is my first Amaryllis and I would like it to bloom again. After reading everything today I realize that I probably shouldn't had planted it in the garden, but it did wonderfully! Pure luck! LOL

Planting it in the garden was a great idea. But I would worry about keeping it in the cold garage now. Is there a place inside where it could go to sleep?

If you have a dark, cool basement, this would be an ideal napping place for your bulb... but as long as your garage doesn't freeze, and the door doesn't open and close allowing freezing air inside, you should be ok.

It's not necessary to add any medium to the pot now... just keep the bulb from freezing or getting wet.

Planting it outside after it bloomed was a good idea, actually... you gave it the chance to recharge from its bloom cycle... and hopefully, it has renewed its energy for its next bloom cycle.

It will require about 10-12 weeks of dormancy... but once you see new growth, or enough time has passed, you can pot the bulb up in a free-draining medium and bring it back inside. Place it in a warm, bright room, water it once, and allow it to awaken and begin to grow again. Once new growth appears, begin watering normally, allowing the medium to dry out in between waterings.

I use a medium that I mix myself... it's comprised of pine bark pieces, perlite, and granite chips. I don't care to use regular bagged potting soils because they hold too much moisture for too long a time... and Hippeastrum bulbs hate "wet feet".

There are some great articles posted in the Container Gardening Forum on soils and water retention... or, you can search here for threads on mediums or soils. It's a subject we discuss quite often.

Sounds like you're on the right track! Good luck!

Thank you Jodi for your wonderful help!

My pleasure, shiane! If you have any further questions, we'd be most happy to help! Welcome to the Forum! :-)

I would suggest a good sprinkling with cinnamon as a natural anti-fungal, and make sure it stays dry and above 40*F.

I tried planting my hippi's in the ground one year, but found that they actually did better in pots with good medium and no competition. I give mine as much full sun as possible. If you put your potted amaryllis outdoors in summer, the original leaves will be burned off by the sun, but replaced quickly with stronger leaves. It works for me!

If you store them in the fridge, be sure to put them in a plastic bag, NOT paper. This will help prevent dehydration.

Good luck!
