Typically used 10-10-10 on my 3 years old green giant. Was considering perhaps I should use liquid this year? Advise welcomed please.

Just for clarification talking about Arborvitae-Thuja-Green-Giant

Nitrogen is the limiting nutrient for most trees, including arborvitae. They have enough phosporus and potassium. Use a lawn fertilizer (without weed killer) that will be high in nitrogen.

Trees don't really need extra fertilizer to be healthy, but if you want them to grow faster, than fertilize.
