When and how much to irrigate
There are over 50 species and varieties belonging to the genus of plants called Celosia. Irrigation is a very important aspect to consider when growing these vegetables. In fact, they can be affected by excessive waterings that easily compromise the root system, leading to the rapid decay of branches and leaves. The ideal is to supply small amounts of water, to be administered whenever the soil is dry to the touch. The water supply must be guaranteed starting from spring and especially during the summer flowering period. At the end of the colorful flower production the irrigations of Celosia plants will be gradually reduced and will become necessary only if they live in pots or if the winter season was poor in rain.
How to take care of it
The annual Celosia plants can be very easily affected by low temperatures, so it is advisable to grow them in pots in areas where the climatic conditions are harsh and the seasons very cold. Instead, if they live in territories characterized by temperate climates, they can be grown without difficulty even in full soil, to adorn flower beds and small borders. The ideal temperature is around 20-25 ° C and they prefer a substratum composed of garden soil, peat and a part of coarse sand. This ensures proper irrigation drainage. They fear the strong winds that can ruin the elegant floral production. To prolong the flowering period to the maximum it is recommended to eliminate the withered flowers, thus stimulating the plant to emit new ones.
When and how to fertilize
The fertilizations of Celosia plants help the flower production and must be dispensed starting from the spring season. For this type of plant the most suitable fertilizer has a more accentuated value of nitrogen and potassium, while the phosphorus remains at a lower level. Plants that grow in full soil can be fertilized with slow release granular fertilizer, to be dispensed in early spring. On the contrary, those that grow in pots can receive a complete liquid solution to be diluted directly in the water intended for irrigation, every 10 days. At the end of the flowering the vegetables perish slowly and die. To choose the best and most suitable product for the growth of Celosia specimens it is always advisable to contact a technical staff.
Celosia: Exposure, diseases and remedies
Celosia specimens that live in the home must be located in areas that are sunny but sheltered from direct sunlight. In fact, prolonged contact can cause burns on the foliage. If the plants grow in full soil, it is important to ensure a cool environment, so as not to suffer during the hottest hours of the day. This type of plant is affected by stagnant water, which can lead to the onset of mold and rot by hitting the roots. In these cases, it may be useful to remove the diseased parts and carry out a repotting with new soil. Furthermore, they can also be affected by aphids, if the infestation is not yet very widespread, it is possible to intervene with a cotton swab soaked in alcohol or use appropriate aficidi.
