Growing Evergreens: The Lowdown on Fertilization

Are you looking to adorn your yard with stunning trees? You might be considering evergreens – those year-round, captivating green giants. But like any plant, evergreens have specific needs, especially regarding nutrients. 

You’ve probably heard about using fertilizers, but the big question is: which one? And, hey, while we’re at it, let’s figure out when and how often to fertilize. If you’re searching for “local tree services in my area” to guide you, Earthworks Tree Services is here for you!

So, When Do Evergreens Need a Nutrient Boost

Your evergreens might be silently screaming for some nourishment. Here’s how to pick up on their subtle cues:

  1. Sluggish growth could mean they’re hungry for some fertilizer.
  2. Needles that seem shorter or less green than usual? That’s a cry for nutrients.
  3. Attempting to grow these trees in tricky sandy or clay soil? They might need a nutritional boost.
  4. If pests, diseases, or the occasional bad weather have had their way with your tree, some fertilizer could help it bounce back.
  5. Are young evergreens looking to establish and grow? Yup, you guessed it. They could do with some fertilizer too.

But the fertilizer aisle can be overwhelming, right? Let’s break it down.

Choosing the Right Fertilizer

So many choices and so little time. Here’s a simple guide:

  • Find a complete fertilizer, meaning it should have the big three: nitrogen (N), phosphorus (P), and potassium (K).
  • Ideally, the ratio should read NPK 10 – 8 – 15. So, 10% nitrogen, 8% phosphorus, and 15% potassium.
  • Evergreens love slightly acidic soil with a pH below 7.0. Get some expert advice if your soil’s pH doesn’t hit the mark.

Timing is Everything: When to Fertilize

Spring is your golden window for fertilizing evergreens. Avoid fertilizing late in summer. Why? Because you’ll push the tree to sprout new growth right before winter, making it vulnerable to cold snaps and possible damage.

A note for the eager beavers: If you’ve just planted or relocated an evergreen, hold off on the fertilizing. Let it settle in, find its groove, and decide if it needs a boost.

Watering goes hand-in-hand with fertilizing. Given North Carolina’s varying climates, ensure your evergreens are adequately hydrated. Need advice on tree care? You know where to find us!
