How do you grow cosmos? Learn these tips and harvest true happiness

To grow cosmos, you first need to buy seeds, and the seeds for planting cosmos must be new seeds from last year. They can generally be bought at flower seed markets, but it is not recommended to buy them online. After buying the seeds, first prepare a flowerpot and potting soil. Usually a clay pot is fine, and the potting soil just needs to be loose and breathable; if it is leaf mold soil with rotted roots, the effect is even better and it even solves the base fertilizer issue.

It is best to sow cosmos in spring, because in spring all things grow and it sprouts especially easily. When sowing, scatter the seeds evenly in the flowerpot, then cover them with a thin layer of soil, and then water them. Remember that the first watering must soak through, so the seeds soak in the soil and sprout faster.

Cosmos is unlike other sown flowers and plants: in the first few days after sowing, it does not like being exposed to the sun, so put it in a cool, ventilated place and let it grow slowly on its own. After it sprouts, it can receive a small amount of sunlight; you can let it get some sun in the morning or evening, which is more helpful for growth.

After cosmos grows to 5 cm tall, it enters the rapid growth stage. After that, be sure not to water it too much and do not fertilize it all the time, otherwise it will affect normal flowering. Wait until the surface layer of soil is dry before watering it again. For fertilizing, use flower nutrient solution, dilute it with water and pour a small amount around the roots. You can fertilize more often, but do not make the concentration too high each time and do not pour too much. In this way, the nutrients will accumulate and be released when needed, and after flowering the blooming period will last longer.

After cosmos blooms, do not fertilize again, because enough fertilizer has already been stored before. Also, if cosmos is fertilized after flowering, the flowers will be burned, so carry out the last topdressing after buds form, and then just wait quietly for it to bloom.

How to grow cosmos: cosmos planting methods

Cosmos is a flowering ornamental plant with bright flower colors and high ornamental value. It blooms abundantly every summer, with a light and lasting fragrance. Some people especially want to grow some themselves, but they do not know how cosmos should be grown, and they understand the planting methods of cosmos even less. Today the editor will give everyone a specific introduction, so you can easily understand how cosmos should be grown.

1. Growth habits

When growing cosmos at ordinary times, you must have a comprehensive understanding of its growth habits. This plant likes sufficient sunlight and is fairly tolerant of poor soil. During cultivation, avoid fertilizer, avoid waterlogging, and avoid high temperatures. Its cold tolerance is relatively poor, and during the growth period it needs fertile soil with good drainage. Be sure not to choose clay soil for growing cosmos.

2. Propagation methods

When growing cosmos at ordinary times, you can actually propagate it by sowing seeds or by cuttings. For seed propagation, early spring is mostly chosen, so that it can bloom from May to June, stop blooming after entering summer, and then bloom again after autumn. During the growth period of cosmos, it can be propagated by cuttings at any time. You can cut sturdy shoot tips from its nodes, insert them directly into sandy loam soil, and place them in a cool environment; after five or six days they will take root.

3. Daily management

Daily management is also very important when growing cosmos. Normally do not let it grow into a tall plant, especially when planting it in a windy environment, it should be cultivated into a short plant. When its seedlings grow to between 20 and 30 cm, they need to be pinched in time, and afterward the new terminal buds should be pinched multiple times. Only in this way can the plant be dwarfed, and this can also increase the number of flowers it produces.

4. Pest and disease control

After cosmos enters the hot summer, it is prone to some insect pests, and spider mites are one of the most common pests. At this time, pesticides need to be sprayed in time, or the environmental temperature can be lowered in advance for prevention. In addition, after the cosmos seeds mature, they need to be harvested in time, dried in the sun, and kept. Only in this way is it convenient to plant them again the next year.

How to grow cosmos seeds: cosmos planting methods and tips

Turning cosmos from seeds into a beautiful flower requires a very long process. Do you know how to grow cosmos seeds so they can produce a beautiful flower? Below we will show everyone how to grow cosmos seeds.

1. Introduction to cosmos seeds

Cosmos is a perennial plant. Cosmos comes from the Mexico region of the Americas, and only after continuous cultivation will it bloom. Cosmos can bloom around June or August each year. The colors of cosmos are very beautiful, and its shape is also graceful and varied.

2. How to grow cosmos seeds——seed collection

Cosmos is mainly propagated by seeds. After the cosmos flowers fade, it begins to set seeds. At this time, carry out seed collection for cosmos. After cosmos seeds are sown into the soil, cosmos seedlings will begin to grow. Those growing cosmos by hand can collect seeds and sow them themselves, but if it blooms in a high-temperature season, it will not set seeds.

3. How to grow cosmos seeds——sowing

After cosmos seeds are harvested, do not plant and sow them immediately; it is best to choose a sowing time. Usually in northern China, where the temperature is lower, it is best to start planting after April until June, when the temperature is more suitable. Other regions can choose a season other than winter for sowing.

4. How to grow cosmos seeds——care

After cosmos seeds are planted, they need careful care to ensure they can sprout and bloom smoothly. Cosmos is a short-day plant, so short-day treatment can be carried out after the seedlings emerge.
