Fertilize at planting and annual in spring with bone meal or a bulb food.
Water well, then leave till they burst out in flower in spring and summer season! After flowering, allium foliage will wither, brown, and go inactive.
Plant them under, behind, and around other perennial plants whose growing foliage will cover the allium foliage later in the summer season when it browns.
Do not cut down the browning allium leaves until fall, that is how they store energy for flowers the next season. (This is why planting foliage plants around them is important.).
