I know that you need to be in a particular region to successfully grow amaryllis bulbs. Zones 9 through 11 will support this delicate flower. Here is a link to growing instructions.
How To Grow Amaryllis

What zone do you live in?
warmer climes, up to USDA Zone 7b new bulbs are planted with other spring bloomers – in fall. Those gifted to you (or purchased plants) can go outside in spring, after the threat of frost has passed. Wait until the plants have finished blooming too. Prior to moving these plants outside, however, you’ll want to gradually acclimate them to their new environment. those being acclimated will need to slowly be introduced to more light anyway. Amaryllis can tolerate both sun and shade fairly well, but typically fares better somewhere in between – like partial shade. Too much sunlight can lead to leaf burn, while flowering may be limited in too much shade. Next, consider the soil in the area you want to grow amaryllis. These bulbs prefer well-draining soil. You can improve drainage by creating raised beds or simply mix in some organic matter, like peat or compost. Amended soil will also provide amaryllis with nutrients for healthy growth. Planting amaryllis outdoors is much the same as in containers, neck deep, keeping the top 1/3 of the bulb sticking up above soil level. Space plants 12-15 inches apart. Water well following planting until established.Amaryllis appreciate at least one feeding upon emergence in early spring. Although not necessary, additional fertilizer can be applied a couple more times throughout the growing season as needed using a balanced fertilizer at the recommended rates. Amaryllis also needs to be kept moist throughout the growing season, though established plants are fairly tolerant of drought. Once planted outside, forced amaryllis bulbs will eventually revert back to their natural spring blooming cycle. Once flowers have faded, remove the stalks. You can expect foliage to remain throughout much of summer before succumbing to fall frosts. 2-inch layer of mulch around your plants will not only help conserve moisture and reduce weed growth, but will offer them added protection once cooler temps arrive. Given adequate amaryllis garden care, you can expect to see beautiful blooms each year. They don’t require much and are fairly tolerant of neglect once established. Should plants become overcrowded, divide the clumps and separate as needed. This can also help with reduced blooming, as can a bloom boosting fertilizer or bone meal.do not remove any foliage until it is completely dead and pulls away easily bulbs will be using the food values of the leaves to grow.
Wait until after last frost.
You are best to put them in a pot so that you can bring them in for the winter. They need a period of dormancy and dark to help them to bloom so inside is the best for this.
Here are some videos for you just to show you how! Good luck to you on planting your bulbs!
If the ground is not frozen at your house, plant them immediately and just wait. If you want to force them to bloom, I don’t think the three weeks before Easter is enough time, but you should have blooms by Mothers Day. This is better done in inside planters so you can better control the light and temperature. Best wishes!
