Usually sunflowers are seen in a single stem. But, my plant has got sub stems and small flowers formed so that it affects the size/growth of large flower. How can I avoid the small stems and make the master/large single flower stronger? Should I cut the small stems? Should the sub stem cutting affect the further growth?

Sunflowers grow either as a single-stem plant or a multi-branched plant. Single-stem varieties produce one large flower per plant, followed by smaller blossoms. Branching types, also known as multiflowering, produce multiple stems and bunches of flowers. You have one of the branching types and cutting them will not produce a single stem. You'll have to get a single-stem type if this is what you're looking for. The type of sunflowers that most people are familiar with is Helianthus annuus, the annual sunflower. You need to look for this type when purchasing plants or seeds. It should also specify on the label whether the type of have is single or multi-branching.
