For several years, I've been visiting the Spring Trials in California and also attended OFA's Short Course in Columbus, OH. At both locations, I've marveled at the tremendous size and luxurious growth of the plant materials being presented. How in the world could I duplicate those results in my own garden?

Turns out, it's a matter of paying attention to detail, and really, not too much hard work.

Here's what I learned:

• Choose the right cultivar. If a grower is showing a specific petunia, don't go generic. Grow the named cultivar and invest in quality plant materials. Learn about the plants' habits before buying. Are they upright or trailing? Do they need full sun or part shade? Group plants with similar growing requirements. Look for plants that are sterile and self-cleaning.
  
  
• Use quality soil. A soilless mix, such as a mix of peat moss, perlite, and other amendments is great for containers. Add some time release fertilizer and polymer crystals to retain moisture.

• Observe how the cultivar is grown for the Spring Trials or other show. If it's in the ground, chances are it will be fine in the ground at your house. If it's in a container, definitely grow it in a container, as you can better control the moisture and nutrients.
  
  
• Feed and water regularly and generously. Remember that the larger the plant, the more water it needs. Never let your plants dry out. Keep the soil evenly moist, but not soaking. Feed a half-strength liquid fertilizer every four days. Spray the same fertilizer onto the foliage and flowers weekly. You might try alternating between a chemical fertilizer such as Miracle Gro and an organic fertilizer, such as fish emulsion. Fertilizer with a higher level of potassium will encourage blooms. 12-55-6 is an example.

These simple tips will yield big results and months of colorful enjoyment. Here are some photos from my own garden. The pink petunia is Proven Winners' Supertunia Vista Bubblegum. What appears to be alyssum is actually Proven Winners' Snow Princess.
