Radishes is perhaps the easiest and fastest vegetable there is. Radishes grow best during the cool weather of spring and early summer or in the autumn and winter (subtropical areas). When radishes are grown in high heat with little water, they will become spicy and tough.

Radishes prefer cool moist soil. Don't let the soil dry out during the growing season. The method I use for growing Radishes is as follows:

  1. Pour your carrot seeds into a 5 gallon bucket along with Carrot seeds for the area you're going to plant.
  2. Mix in soil or sand. Make sure you mix well.
  3. Broadcast over the area you're planting.
  4. Water well and never let the area dry out.

This is intercropping.

Within a week your Radishes will germinate first and by the time your carrots begin to germinate and grow you will be harvesting your Radishes making room for your Carrots.
