Radishes are very easy to plant. Radishes are also fun to grow because the appear much faster than other vegetable plants. You do not need a sprawling garden to grow radishes. You don't need a well tilled lawn and fertilized soil in your back yard to have tasty radishes.
You can grow radishes right on your deck outside of your home. I grow them right on my balcony at my apartment. It is fun to do. You basically just use some decent soil, plant wait a month or so and your fresh radishes will begin to spout from the dirt.

Many times we buy plants on impulse then find there is nowhere in the garden that really suits them. Before buying plants carefully examine your garden to see how much sun and shade it gets, whether the soil is well drained or waterlogged and whether your aspect is sheltered or windswept. You'll then be equipped to go and buy the best plants for your situation; shade-loving plants for the sheltered areas, sun-lovers for the warm spots, drought-resistant plants for the parched areas which may be either sunny or shaded, and swamp plants for the poorly-drained parts.
