Is Cosmos annual or perennial?
Both the perennial Cosmos atrosanguineus and the annual cosmos are upright plants, making excellent additions to a summer border. The annuals are particularly effective when massed and provide flowers for cutting over a period of months. Annual comos are easily grown from seed.
Do marigolds self seed? Do marigolds spread? Marigolds are rapidly growing plants and most varieties are self-seeding, which means they will drop seeds and spread throughout your yard or garden. Limit the ability to self-seed by deadheading before blooms go to seed.
Are sycamores a problem?
Sycamores are notoriously prone to anthracnose, a disease which can cause massive leaf drop in early summer. Usually a cosmetic rather than life-threatening affliction for the tree, it generally re-foliates in short order. As if that weren’t enough, sycamores are prone to heartwood rot.

Does Echinacea self seed? Echinacea purpurea will typically self-seed annually in the landscape; however, if growing plants from scratch, seeds can be started outdoors in the spring or summer, up to two months before frost. Keep in mind that plants started from seed can take two or more years to develop into a sizeable plant.
How long do seeds take to sprout?
How Long Does It Take For A Seed To Germinate? It takes about two weeks for most seeds to germinate, while other seeds can take much longer. Seeds should sprout growing within a month of planting when sown in the right conditions. If you don’t see sprouts, then you need to determine the cause.
Can I grow seedlings outside?
You can start to harden off your seedlings once they’ve grown at least two to three sets of leaves. At that point, they’re mature enough to move outside. About 7 to 10 days before your seedlings are ready to be transplanted, take them outside and leave them in the shade for a few hours in the morning or afternoon.

How often do you water cosmos? Water regularly until plants are established or if it is unusually dry. Make sure you don’t over-water cosmos; over-watering and over-fertilization can lead to plants with fewer flowers. Cosmos can tolerate dry soil, even in a hot, arid, sunbaked spot.
Do cosmos like sun or shade?
Light: Cosmos prefer full sun conditions, except in extreme heat where they can tolerate part shade. Soil: Prepare the garden with loose, weed-free soil. Cosmos prefer dry, arid soil over wet conditions.
When should you plant cosmos? Sow cosmos in early spring so the plants can become established before hot weather comes.

Plant seeds in prepared soil about 2 inches (5 cm) apart and one-half inch (1 cm) deep.
Can you put cosmos in pots?
Cosmos flowers can be successfully grown in containers. Species plants can grow as much as 6 feet (2 m.) tall, so look for dwarf or compact cultivars for containers. Of the 20 species of annual and perennial cosmos flowers, cultivars of C.
