Adding a flower bed to your landscape can cost the moon or a reasonable sum of money. Gardens can be elaborate or simple, depending on the amount of effort placed in soil preparation, plant purchases, edging and mulch. Learning how to make a cheap flower bed begins with understanding that the largest gardening expense lies in the purchase of flowers. Sturdy annuals and perennials bought from the nursery can break the budget when adding a flower bed to your landscape. Cheap flower beds can be created easily as long as the soil provides adequate nutrients for flowers to survive.
Dig up all the grass in the garden area by digging deeply with a shovel about 6 inches beneath the surface. Grass throws out roots called rhizomes that travel in many directions under the soil surface. Shake the dirt off each clump of grass and discard or place in another spot on the lawn as patch. Dig up any weeds and dispose of them in yard waste bags to prevent spreading.
Add a layer of peat moss about 2 to 3 inches thick across the garden surface. Work this into the top 5 inches of soil to improve drainage, add nutrients and break up thick clay soil. A rake and hoe work best to incorporate the organic matter into the soil layers.
Fill a bucket with the soil mixture. You'll be using this fresh dirt to blend with the perennial seeds for spreading. Smooth out the garden surface using a rake until level.
Water the garden lightly using a garden hose to dampen the flower bed. Do not soak the soil because this won't promote quick germination of the perennial flower seeds.
Follow the instructions on the packet for planting the perennial seeds. These seed mixtures offer a variety of blooms to fill the garden with flowers throughout the growing season. Most are hardy and provide a quick and cheap solution to add color to your landscape.
Pour half the container of seed mixture into a clean empty coffee can. Add 2 cups of loose peat, soil or sand (not beach sand) to the seed and mix it up. This method allows for more uniform spreading of the seed layer. Spread seed over the entire planting area then mix up another batch with the remaining seed. Spread this second batch over the entire garden area.
Use a roller to compress the seed into the soil or walk lightly on the soil surface until the seed is pushed into the soil. Seeds must have direct contact with soil to begin germination.
Water the area lightly using a fine mist on your garden sprayer. Seeds should germinate at varying rates within two to three weeks with regular watering.
