Keeping Things Tidy
Annuals will flourish when provided with the best possible growing conditions. However, there are a few simple care techniques that will help increase and control their growth.
- Pinching Back: To encourage plants to fill out, remove the growth bud at the end of the main stem when the plant is in its rapid growth stage that precedes first flower bud formation. For bedding plants, the best time to do this is when you're planting them out in the garden. They're at a good stage of growth and, in addition, the removal of some of their foliage will help balance any root damage they may suffer in the transplanting process. Plants grown from seeds sown directly in the garden should be pinched back when they're 3 to 4 inches tall.
Simply pinch out or snap off the last inch or so of the main growing tip. This will redirect the plant's energy from this single shoot to numerous latent side buds -- there is a latent growth bud located at the node (the point on the stem where each leaf is attached). Several days after pinching, you'll see several small shoots pushing from the remaining stem. These will grow into a cluster of stems to replace the original single stem. The plant will be shorter, stockier, and fuller than if no pinching had been done. It will also be neater-looking, more compact, and have many more branches on which to produce flowers. A second pinching can be done two weeks after the first one if an even fuller plant is desired.

- Deadheading: Once annuals begin to bloom, it's important to remove spent flowers promptly for several reasons. First, once the flower dies, it detracts from the good looks of the garden. Second, even though we say it's dead, it's actually very much alive and continues with its growth toward seed production. This process pulls plant energy that would otherwise be available for new foliage and flower production into the seed head. Third, removal of spent flowers helps to quickly redirect plant energy to side shoots for smooth and speedy transfer to new growth.
To make this rerouting most efficient, always cut back to just above the first side bud that is already beginning to grow. If there is no active side bud below the bloom, cut back either to a side branch or immediately above a leaf node where a latent bud will be likely to push out new growth. Make a clean cut with a sharp-bladed knife, since ragged cuts take much longer to heal and are likely sites for entry of rot and disease. These rules for cutting apply to the removal of cutting flowers as well.Occasionally it becomes necessary to cut back growth in order to keep a plant from becoming leggy or from drowning out neighboring plants. Cutting back should be approached in the same way as removing dead flower heads. Always cut back to a side growth shoot or branch that is headed in the direction you want future growth to go. This way you can steer and control growth as you see fit.
