Another tip: you can root the cosmo cuttings. They root easily in water or just stick them back in the dirt. Love them🌼

I am in Florida and decided to begin Cosmos from seed in pots. When they got about 12 inches tall after pinching I decided to put them into the ground. Meanwhile a couple days later I noticed two of the 6 plants were cut off by 8 inches, decapitated and leafless. Next thing you know all of them day after day were victim to the same thing. Chopped off and only a stem 5 inches remains. What do you think could have done this and do you think they will grow back?

Hello Ellie, appreciate the comment. Pruning back to create a bushy plant is perhaps the best tip of them all.... and this applies to many plants.

thank you ! never knew you could clip them back. mine self seed in zone 5b. I, usually spend two weeks digging seedlings out of my lawn and transplanting them back into the flower bed...one year close to a hundred !

@johnnyAGardening Жыл бұрын

We often deadhead some of ours to prevent so much self seeding, however, at least they are easy to pull out if not wanted. The pinching back makes a much bushier plant.

I grew cosmos for the first time this year. Put the seeds in the ground later April. Now I have these massive cosmos bushes. Still haven't had any flowers come out and don't even see signs of buds.

@johnnyAGardening Жыл бұрын

The three main reasons that Cosmos do not flower are: Lack of sun, they need lots of sun to set buds. Over fertilising. Too much fertiliser leads to lots of foliage and no buds. Cosmos like a poor soil. Over watering. They need good drainage and not a lot os water. Hope these hints are a help.

Yes seedlings require thinning. The general rule is to plant them at 12 inches (30cm) apart. As you prune them early on they branch out/ We sometimes plant the small growing ones closer, in good soil usually 8 inches (20 cm)

So now trying with just grow lights and no humidity dome?

Chocolate Cosmos (cosmos atrosanguineus) seeds are generally sterile, propagation is by division or other vegetative methods. Purity and others should be OK and yes lower the humidity, just a little moisture.

Meaning when it is grown at a temperature of 25 degrees, for example, and then it germinates and the plant grows well between 20-16 degrees Celsius, as was indicated to me, but when it falls below 16, does its growth stop! How many blooms it needs! I live in Bahrain and our weather is hot but there is no frost, the lowest temperature that can drop is 11 or 10 degrees Celsius!

We wait until the plants are around 6inches (15cm) tall so as to avoid snail and slug damage. You can do it at less than this. A week or two after transplanting we usually pinch them back for bushier growth.
