Please can you define Early Spring?
I recently bought many baby Conifer trees (from Oregon). I live in Morro Bay California on the Central Coast. I have been doing research on the care of my babies. Soil, sun fertilization....they all say, Fertilize "Early Spring" I can't find "Early Spring" defined anywhere. February? (late winter?) March? April? Too late? I have Black Hills Spruce, Jacobsen Mugo Pine, Nest Spruce, Dwarf Alberta Spruce

Thank you for your question. First, newly planted trees don’t need fertilizer the first two years after planting. But after that, fertilize when you begin to see new growth on the plants. They don’t need fertilizer when they are dormant, because they are not photosynthesizing much, if at all. ‘Early spring’ varies from year to year, and region to region. Newly planted trees are more in need of regular watering than added fertilizer. Here’s an Extension article on the topic: http://sjmastergardeners.ucanr.edu/Landscape_Trees/ Good luck!
