The type of soil that you plant your hyacinths bulbs into is not very important, but what is necessary is that it has good drainage and compost to regulate temperature and moisture. If you plan on planting your hyacinth bulbs in pots, we recommend you plant them with their neck exposed. If you are planting the hyacinth in the garden, the bulbs should be a little deeper to keep them protected from the warm sun. Once planted, add mulch to insulate the bulb against warmth and preserve moisture. Plant them in semi-shaded areas and towards the end of April when temperatures are cooler.
