About Black spruce

Black spruce is a super rare houseplant 🌿 that is easy to grow and needs regular watering to thrive. They do best in long-lasting, direct light ☀️ and should be less than 1 foot from a window.

Black spruce likes soil that is well draining. Your plant shouldn't need added fertilizers if you repot each time it doubles in size.
