When to plant the bulbs: period for planting flower bulbs, so as to have abundant blooms at any time of the year.

When to plant the bulbs?In a sense, it is always a good time to transplant a bulb into the ground. There are, in fact, bulbs that are planted in spring, bulbs that are planted in summer and bulbs that are planted in autumn… And so we have summer flowering bulbs, spring flowering bulbs, autumn and winter.

When to plant the bulbs

In spring, bulbs that bloom in summer are planted, such as:

  • Gladioli,
  • Dahlias
  • Zinnias
  • Anemones
  • Agapanti
  • Begonias
  • Calle
  • Glorious

The bulbs that can be planted in spring actually have a certain time tolerance. To always have new blooms or blooms to climb, starting from spring you can plant new bulbs at intervals of two weeks until the month of July.

In autumn, however, you can plant the winter and spring flowering bulbs. Planting can take place from the end of summer until late autumn. In the south ibulbs can also be planted in winter, until the ground freezes.

Among the new bulbous plants, still little known in our country, there is the species coming from South Africa, the Veltheimia bracteata, which with its pink flowers begins to color the garden in February. Flowering continues throughout the spring if you follow the strategy of planting to climb!

The South African speciesValtheimia bracteatait can be grown in the open ground only in southern Italy. In the north it should be cultivated in pots, so as to place it in a place sheltered from frost during the winter.

When planting the bulbs

Always talking about bulbs that bloom in spring, autumn, you can plant:

  • Hyacinths
  • Daffodils
  • Iris (recommended the more showy Iris Magnifica)
  • Fritillaries
  • Leucojum
  • Dichelostemma
  • Tulips
  • Camassie
  • Scylla

In autumn, ornamental garlic can also be planted. The plants listed above can bloom until June - July and can be planted from early autumn to early winter.

Winter bulbs

Some bulbous plants resist cold well. Many varieties of ornamental garlic resist disease well and canplantin the open ground even in the mountainous areas of northern Italy.

Among the cold resistant species we point outAllium amethystum.The name "Amethystum" is due to the purple color which recalls that of the amethyst quartz crystal. This flower can withstand even -20 ° C.

Camassia is another bulb plant that you canplantin areas where the cold limits the growth of other flowers. The Camassia leichtlinii species manages to bloom even with temperatures around -25 ° C. Its flowers are blue and they manage to create interesting coloring spots in the garden.

How to plant the bulbs

After seeingwhen to grow flower bulbs, analyzing the various periods of the year most suitable for planting, let's seehow to grow them.

Therecultivation of bulbsis simple. First of all, let's start with the planting. The rule to follow to understandat what depth to bury the bulbsis simple:

  • The bulbs must be buried at a depth equal to double their height.

At what distance to place one bulb from the other? Again, the rule to follow forgrow the bulbssohomogeneous, so as to obtain flower beds without uncovered areas, it is simple:

  • The space to be left between one bulb and another is equal to double the height of the bulb + 1.5 cm.

How to grow bulbs?

After making the hole, the bulb must be placed inside with the sprout area facing upwards. Immediately after planting it is necessary to irrigate abundantly.

If you wantgrow bulbs in pots, you will need to keep the soil moist until the plant releases its first shoot. The frequency of irrigation varies from the period of planting. The rules to follow are:

  • The bulbs planted in autumn, in the open ground, should not be irrigated ... the rains will take care of it! If you wantgrow bulbs in pots, then, you will have to wet the soil every 10 days.
  • Those planted in spring need more constant irrigation, paying attention to the frequency of rains. In case of drought, the bulbs planted in the ground must also be wet.
  • The same goes for the bulbs that are planted in late summer and that bloom in autumn (like cyclamen).

To improve flowering and lengthen its time, it is recommended to administer a fertilizer. In general, it might be useful to add a handful of gradual release fertilizer to the soil at the time of planting. To support flowering, however, it is useful to use a quick-release liquid fertilizer.

Fertilizer for flower bulbs

Among the various products on the market, I would like to point out the "Compo fertilizer for bulbous plants" which can be bought on Amazon at a price of 13.99 euros and free shipping costs. It is a specific fertilizer for bulbous plants, the manufacturer recommends administering it every 10-15 days, however, we recommend adding liquid fertilizer only when the vegetation is abundant, just before the flower shoots are emitted. In this way the flowering will be more abundant.
