Italian stone pines are neither houseplants nor hardy outdoors | Residence & Backyard garden

Right after 33 yrs producing a gardening column for the Put up-Dispatch, Chip Tynan is retiring from the Missouri Botanical Backyard. We are rerunning some beloved columns for a several weeks, but the garden will resume the column soon. Make sure you continue on to deliver inquiries to the handle below.

Q • I received an Italian Stone Pine as a residing Christmas tree reward. I have been trying to keep it indoors, but I ponder if it can be planted outside?

A • The Italian Stone Pine (Pinus pinea) is not hardy in the St. Louis spot and really should not be confused with the Swiss Stone Pine (Pinus cembra), which will survive in our local climate. Italian stone pines are indigenous to northern Mediterranean areas in Europe. In this nation, they are principally grown in California and locations of the western states that are not subject matter to freezing climate. However they will not survive our winters if planted outdoors, neither can we think about Italian stone pines to be houseplants. If retained indoors in ordinary warm problems, they will eventually get rid of their vigor and drop.

Provide your plant with awesome evening temperatures in the 40s and a shiny sunny window. A cool greenhouse or a sunporch would be excellent. For the remainder of the wintertime, enable the soil to dry to some degree in between waterings. Place your plant outdoors for summer time, with some safety from the hottest afternoon sunshine. Continue to keep the soil evenly moist and fertilize about as soon as a thirty day period right until slide. Provide it back indoors in tumble when evening temperatures fall into the lessen 40s.
