Lush Foliage:

It leads your boxwood to grow poor due to environmental stress and eventually death. Look for the one that provides insect repellent when shopping for fertilizer for your boxwood.

Winter Protection:

During the winter season, Boxwood struggles the most. They can get burned and go through serious damage if they have not tended properly. When leaves begin to lose moisture, due to the soil being frozen, roots find it difficult to replace the moisture.

How to Spread Boxwood Fertilizer?

boxwood landscaping

Even if it is fully-grown, Boxwood requires fertilizer. Although different stages require different fertilizer application quantities and procedures, you can find the process effortless with a little awareness and care.

Growth stage Appling Plant Food

When the boxwood is being planted, this stage looks identical. Only prepare a boxwood zone (they grow best in 6-8 zones), dig a large hole that is twice the size of the root ball, and check the acidity of the soil (ideal pH level is between 6 to7).

It’s time to put the boxwood inside the hole if all is fine. Be careful not to damage the roots. Fill 1/3 of the soil with compost once the boxwood is put in place. To cover up the rest of the hole, add garden soil and apply your granular fertilizer above it.

For now, gently water the plant and continue to water each week during summer and spring.

With the water, the fertilizer will dissolve and slowly release nutrients which will then be absorbed for full effect by the root of your boxwood.

The Mature Stage Appling Plant Food

It is comparably simpler to add fertilizer during your boxwood’s mature stage. If you believe your precious boxwood needs fertilizer, figure out the width of your boxwood using a tape measure. A general rule of thumb is, you need to add about 1 cup of fertilizer for every foot of width.

Only spray granular fertilizer along the drip line and gently water it. In the mature process, this is very much about fertilizing your boxwood.
