On this week’s episode, the guys talk about planting and growing onions. They talk about the difference between short-day, intermediate-day and long-day onions and how you can determine which type is best for your area. They also discuss the varieties that have worked well for them which include Texas Legend, Yellow Granex, Southern Belle Red and Red Creole. Greg and Travis discuss how they like to plant their onions thick and thin later when harvesting some as green onions. Travis mentions that growing onions can be broken into two phases — the foliage stage and the bulb stage. He explains that you want to grow as much foliage as you can, which in turn will create nice, large bulbs during the latter stages of the plant growth. They also talk about fertilizer needs for onions. They mention that onions need a complete fertilizer with phosphorous and potassium initially, but then mostly nitrogen throughout the rest of the foliage stage.
On the Show & Tell segment this week, they talk about some radishes that were just harvested from Travis’ garden. Greg mentions that he recently planted several rows but is concerned about the heavy rains affecting the germination. Travis also explains the difference between multiform and monogram beet seed, and the need for thinning when using multiform beet seed. He prefers to grow beets from transplants because he can thin in the greenhouse versus thinning in the field.
On the Q&A segment, they answer questions about phosphorous and glyphosate. Greg explains the different sources for adding phosphorous to garden soils, which include soft rock phosphate, hard rock phosphate, bone meal and triple phosphate. He mentions that soft rock phosphate would be his preferred organic solution, but that the inorganic forms work very well also. Travis explains that glyphosate will not kill mature weed seeds and is only engineered to kill the plant.
