Here are some answers to have a beautiful flower garden this summer… From spring they appear on the stalls of garden centers, the first signs that sunny days are coming! Passing the winter in the form of seeds and sown in spring, the annual flowers bloom in summer to disappear with the first cold; however the seeds they have generated and which have fallen to the ground can "re-germinate" the following spring, and this for 2-3 years. The annual plant thus reproduces thanks to its own sowing. However, after a few years, you must renew your annual plants, because everything is of course decreasing. This distinguishes them from perennial plants valued for their longevity. However, some perennial plants of tropical or subtropical origin are considered annual due to their premature disappearance due to climatic conditions. Not resistant to frost, they die once the summer is over. This is the case with geraniums, fuchsias, impatiens, nasturtiums ... Unlike perennials, annual flowers must be renewed ... therefore every year! A disadvantage for some, annual plants allow you to change the decor as you wish.

Plant and sow annual flowers
Clods to plant If sowing is an economical solution, you can choose to buy ready-to-plant flowers. Save time guaranteed! Only downside, the choice of species sold in plants is more limited than in sowing. Annual flowers are sold in garden centers in small clods. They can be planted from mid-April when the risk of frost is over. Dig holes larger than the size of the root ball, then carefully remove the young plants from their pots. Install them at the correct depth: the base of the rod at surface level. It is preferable to wet the roots, which are often too dry, after unpotting. Plants should be spaced 10 to 20 cm apart. The addition of potting soil is always advised, without forgetting watering at the end of planting. Sowing in place, in the ground Sowing in the open ground in the spring is easy and works very well for most species. It involves burying the seeds where they will grow and flower all summer. You can thus directly sow the seeds of certain annuals, "the annuals to be sown in place" such as the belle de jour, the immortelle, the lavatera, the poppy, the marigold, the flax, the lark's feet, the cosmos, just to name a few.
Always be sure to prepare your soil well before planting. The beds must be digged and enriched by adding soil. Depending on the type of seed, three sowing techniques can be used. On the fly, in the rain, it allows seeds to be dispersed in disorder, therefore obtaining natural-looking beds. In line, made in a small furrow, it gives an orderly appearance to flower beds and flower beds and allows you to form colorful drawings in the garden. Finally the sowing can be done in poquet. The seeds are placed in groups of 3 or 4 in each hole to keep only the most beautiful plants. Sowing can be staggered from April to mid-June and it may be advisable to sow 15 days apart in order to obtain a succession of flowerings. Annual flowers: "hot" sowing Depending on the hardiness and the life cycle of each species, sowing can be done, not in the ground but "hot" in order to favor transplanting in place when the last frosts have passed. Non-rustic plants which have a fairly long development and are difficult to withstand the cold therefore need to be sown under a frame, in a greenhouse or inside the house. Sowing can be done from January for geraniums, petunias and begonias. The faster growing flowers will wait until March-April to be sown, this is the case for Indian roses, impatiens, petunias, lobelias, verbena… Fill your mini greenhouse with potting soil, scatter the seeds and cover them with 0 , 5 cm of sieved potting soil. The culture should be installed near a window at an ideal temperature between 18 and 20 ° C. Generally speaking, the germination of annual plants is very fast (3 to 15 days). Once your seedlings have 4 to 6 leaves, transplant them into small pots containing a mixture composed of half of compost and half of soil from the garden where they will grow, waiting to be installed in the garden when the risk of frost will be completely ruled out. When the seeds have germinated, thinning must be carried out, which consists of removing the excess seedlings, to allow them to have room to develop well. You just have to place them in the four corners of the garden ... without moderation! Thanks : Olivier Lefebvre - Botanic.
