How to plant summer bulbs

Now that we know the summer bulbs, we have to choose the ones that we like the most and plant them in spring. But how do you do it? Namely, How are they planted? To get an interesting amount of flowers during this season, it is very important to start on the right foot, since otherwise you could have problems budding.

So, let’s see how they are planted in pots and in the garden:


If we want to have a spectacular terrace full of bulbous plants, we have to:

  • The first thing to do is fill a pot of 20cm in diameter (or more if the bulb or rhizome is larger) with substrate up to about half. As they are very resistant plants, we can use a universal growing substrate.
  • Next, the bulb is inserted with the narrowest part facing us.
  • Finally, it is covered with substrate, and watered.

In the garden

If we decide to plant bulbs in the garden, we have to:

  • Make trenches about 30cm deep where we want to have them.
  • Mix the soil with a universal growing medium.
  • Fill the trenches about half way with the mixture.
  • Place the bulbs leaving a distance of 15cm between them.
  • Cover them with the mixed soil.
  • Give them a generous watering.

Problems that bulbs can have


Bulbous plants can be affected by pests or fungi. Let’s see what they are and how to combat them:


The main pests they can have are:

  • Cottony mealybugsThese insects land on the underside of leaves, but can be easily removed with a cotton swab dipped in soap and water.
  • Aphids: they are very small insects (less than 0,5cm long) that settle on the leaves and stems. Eliminate them easily by leaving a bottle with water and tobacco butts for 12 hours, and filtering it the next day to fill a sprayer.
  • Sea Conches: they can cause serious damage to bulbous plants in humid environments, so it is advisable to place low containers with beer around them to control their population.


If we talk about diseases, these are the most common:

  • BotrytisAlso known as gray mold, it kills leaves and flowers. It can be prevented by watering little. If you already have it, the affected parts have to be removed.
  • Rot: caused by the fungi Phytophthora or Fusarium. It is caused by overwatering or poor drainage. If the plant is affected, unfortunately the only solution is to throw away both the plant and the substrate, and thoroughly clean the pot before using it again.
