image Photo of flower buds, tree is covered in them. Unfortunately, I plan to remove all fruit for the first 1-2 years at least. This tree is too scrawny to hold any fruit.

Average outdoor weekly temperature is 33.6F. The greenhouse average weekly temperature is 51.5F and its thermostat was set around 45F. Today I've bumped the thermostat up to 55F to try and get some of the greenhouse trees to flower/grow.

Motivation to get this tree is Oroblanco and Melogold are on a short list of grapefruit known to do better in cooler coastal areas. Large fruit can generally take longer to ripen so I choose grapefruit cultivars more carefully for the PNW.
