Spring flowers bring in the warm weather with a colorful display that, if planned properly, will last for a long time. Growing the flowers takes a little preparation of the soil as well as timing of when to do the planting. If you plant already-grown plants that you buy at the store, you don't have to prepare as early, but it will still have to be done.
Plan out where you want the flowers located. Try to spread them out so flowers that bloom at different times are scattered. This way as one type of flower stops blooming, others will be starting. The spread will scatter color throughout the garden no matter what time of spring.
Plant spring bulb flowers in the fall of the year before. If you live in a warm area of the country, you can wait until late fall, but all bulbs need a certain amount of time in the ground during cold weather in order to grow. Plant them in holes with the pointed end up. Cover loosely with soil and water.
Plant new perennials and annual flowers in the spring after the last of the frosts so that the foliage isn't damaged. Mix some fresh top soil into the dirt before planting.
Cut back perennials that are already planted from previous years. Do this in the fall when green foliage is dying out. This way the flowers will be ready for new growth the next spring. Annuals can be cut down as well. They won't grow back, but seeds are normally produced that will grow up the next year.
Water flowers to keep the soil damp during times when there is no rain. Add plant food to improve health and increase growth. Bulbs need a phosphorus fertilizer sprinkled on top of the soil. Follow instructions on the mix for the amount of soil you want to cover.
Snip off dead blooms so that the flower doesn't send unneeded nutrients to an area that has no use for it. In some cases this will encourage new growth and more blooming flowers. With plants that develop seed heads after flowering, wait on the deadheading until after the seeds have been dropped, or at least leave a few intact for that purpose. Also, pinch back perennials to the first leaf node to encourage more growth.
Cut out stems of plants that clump together like daisies to thin them out. Select stems throughout and snip them down to the ground. This will provide more air circulation.
