Caring for Summer Bulbs Plants

To plant summer bulbs, you must first consult which species you have and make sure you are going to plant them at the right time because although most are planted in spring, this is not true for all.

Plant the bulb with the pointed side up, which is where it will grow. Depending on the size of the bulb, it will need a depth of between 2” and 8” (5 and 20 cm). It is important to have loosened the soil beforehand, which should offer good drainage and be rich in nutrients. We recommend using a mixture of peat, worm humus, and coconut fiber in equal parts, with the addition of vermiculite and perlite. The bulbs to be planted should be hard and dry to the touch: the opposite usually implies that they are rotten.

Choose a location according to the light needs of the plant and water by spraying after planting, bringing moisture to the soil but always without puddling. Most summer bulbs are especially sensitive to excess moisture, which makes them sick and kills them.
