I found the perfect plum in the sale yard. Prunus ‘Nichols’ shows off bright red foliage and deep red fruit, inside and out. It was hardy to minus thirty degrees. Less hardy dwarf pineapple Ananas comosus ‘Sugar Loaf’was a great candidate for greenhouse culture. Fruiting tropicals can spend summers outside, and then reside in a bright glasshouse for the rest of the year.
I asked Jim for a tip on how to determine which plants would be happy growing in greenhouses. He told me to look for those less-vigorous varieties that are naturally dwarf or grow slowly. The small fig tree, Ficus carica ‘Negronne’, with its dark red-fleshed fruit, flourishes in container culture. Jim also liked dwarf citrus. He gave me terrific advice for growing citrus in containers—use acid potting mixes—the kind for rhododendrons. The acidity of the free-draining soil mix allows plants to take up more essential nutrients, including iron. (For other tips on citrus, see my column, “What’s Wrong with my Plant?”)
