Josh McGillCUPS, Economics, Research

High yields of HLB-free fruit can hypothetically be sustainably produced in citrus under protective screen (CUPS), Arnold Schumann said at a Dec. 14 field day at the Citrus Research and Education Center (CREC). He backed that up with data showing high yields from Ray Ruby grapefruit planted at high densities and fertigated in CUPS. Trees in his CUPS facility are …

Seeing Success With Louisiana Citrus Grown Indoors

Josh McGillLouisiana

A three-year Louisiana State University Agricultural Center (LSU AgCenter) study is investigating the pros and cons of growing citrus inside or in containers. “So far, we are finding that the pros are outnumbering cons,” said Anna Timmerman, LSU AgCenter horticulture agent in St. Bernard and Plaquemines parishes. Early results of Timmerman’s research show that growing citrus indoors produces a high-quality …
