Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.

How to tell conica jean's dilly spruce needs water

A calendar is the worst way to water conica jean's dilly spruce. Check the plant and the soil instead — for this species, look for these signals in order:

Wilting, bud and flower drop, and crispy leaf edges.
A faded, stressed look and a rootball that has pulled from the pot sides.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For conica jean's dilly spruce, the levers that matter most are:
