What time of year do you plant cosmos seeds?
Before the hot weather arrives, sow cosmos in early spring. When the plants have at least five leaves, they can be started indoors in containers or purchased as bedding plants. The prepared soil has seeds in it that are about 2 inches (5 cm) apart and one-half inch (1.2 cm) deep. Keep the soil moist, but not soggy, and allow the seeds to germinate in a warm, well-ventilated area.
Seedlings should be transplanted to a potting soil mixture of 1 part peat moss to 3 parts perlite or vermiculite. If the mixture is too wet or too dry, the plant will not grow well and may die. To prevent the roots from drying out, cover the pots with a layer of plastic mulch, such as newspaper or newspaper towel, to keep them moist and prevent them from rotting.
Should I soak cosmos seeds before planting?
The more sustainable CowPots are the best place to start your seeds. Once your plants have hardened off, you can put them into their planting hole. It’s a good idea to thoroughly soak the pots, and moisten the soil around them with a garden hose. Once your seeds have germinated, it’s time to transplant them into their new home. You’ll want to plant them in an area with good drainage, as well as a well-drained potting mix.
If you’re planting in a container, make sure the container has drainage holes in the bottom so that the seeds don’t sink into the ground. The best way to do this is to dig a hole large enough for the seedling to fit into, then fill the hole with soil from the top of the pot. This way, the roots will be able to get the water they need to grow.
Do cosmos come back every year?
Most of the cosmos are annuals, meaning they don’t come back every year. You will need to replant the seeds the following spring in order to have blooms every year. Chocolate cosmos is a perennial plant that can be grown year-round. It grows to a height of 2-3 feet, and can grow up to 20 feet tall.

Is cosmos an annual or perennial?
Most cosmos varieties are annuals, which means they won’t return year after year. Each spring, you can collect the seed and sow new cosmos. If it is given enough time, chocolate cosmos will return each year.
The best way to tell is to look at the leaves of the plant. The leaves will be yellowish-green, and the stems will have white hairs. If you see the hairs on the stem, it means you have the right kind of cosmos.

How many seeds should I plant per hole?
Two to three seeds should be planted per hole. Not every seed that is planted will sprout. The number of plants you want to grow will be ensured by over seeding holes, cells, or pots. If you want to plant more than one type of plant in a hole, you will need to divide the hole into two or more sections.
For example, if you have a 2-inch hole in your garden, divide it into four sections and plant two different types of vegetables in each section. You can also plant a variety of seeds in the same hole to increase your chances of success.
