Know the requirements.
Oftentimes, beginning or inexperienced gardeners will make the mistake of purchasing a plant simply because it looks pretty. This is a mistake because in order for a plant to flourish, certain things like soil, climate, region, sunlight, and watering conditions all need to be taken into consideration. Before purchasing seeds or plants, read the lighting, soil, and watering requirements to make sure you plant them in the right spots.

Periodically deadhead your plants
One of the easiest and most effective ways to keep your flowers blooming is to deadhead them. Basically, this is just removing the worn-out blossoms. Flowers exist to produce seeds, so once the seeds have been produced, they won't flower anymore. Both perennials and annuals will re-bloom once they have been deadheaded. The only exception to this is flowers that bloom on a single stock.

To deadhead a flower, just snip the entire stalk of the used up blossom off the plant, staying as close to the base as possible. Plants that have multiple flower buds on a stalk, however, can be difficult to deadhead. One of the easiest ways to handle this is to wait until most of the buds have become worn-out. Then, trim back about a third of the plant, which result in a number of new flower buds.

Don't over water.
Some think that a plant can never get enough water. However, this is not the case. Over-watering your plants is a common mistake many gardeners make in the beginning. As a result, the plants die and the flowers stop blooming. Follow the moisture requirements set forth for the plant; most seed packs or flowers will have instructions on how often to water the plant. If the plant is in an area where it rains frequently, you can significantly cut back on the amount you water it.

Use fertilizer.
Most plants will benefit from some type of food or fertilizer. It requires energy for plants to bloom, so if your plants flower frequently, they will need more food in order to keep blooming. You can ask the experts where you purchased the plants what they recommend, or you can get a good all-purpose fertilizer and plan on using it every 3-5 weeks, depending on the plant's size and nutritional requirements.

Another thing you may want to consider to keep your flowers blooming, especially if they bloom often, is to put in a dose of triple phosphate. Think of this as an energy supplement. This is good early in the season and boosts root development and the bud set. As with any fertilizer, be sure to follow the directions, as too much could end up killing your plants.

It is possible to keep your flowers blooming year-round, especially in the hot summer months. Keeping your plants watered regularly, fertilized, and trimmed and pruned will help to ensure your garden stays colorful.
