How to Care for Green Pillar Boxwood

How do I prune Green Pillar Boxwoods?

How do I prune Green Pillar Boxwoods?

To maintain the Green Pillar Boxwood in its most natural shape, thinning is the most appropriate way to prune for an informal look. To thin, prune selected branches throughout the shrub to the main trunk, to a lateral branch or to a lateral bud. The older and diseased branches can be pruned to the ground. This method of pruning allows the center of the boxwood to receive light and air, improving the health of the shrub. Boxwoods have a tendency to become very dense, especially if it has been sheared over a long period of time. This not only can cause fungal diseases, but also causes the leaves to grow just on the edges of the shrub. The inside of the boxwood then turns brown where leaves have died due to a lack of light. Thinning allows the leaves to grow along the entire branch, not just the tips, resulting in a fuller look. Thinning can be done any time of the year except about six weeks before the first frost.

How do I mulch Green Pillar Boxwoods?

How do I mulch Green Pillar Boxwoods?

We highly recommend that you mulch your Green Pillar Boxwood with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do, but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away that will compete with your new investment for water and nutrients. A 2 to 3-inch layer of mulch is sufficient, but remember to take care not to cover any part of the stem of the plant with mulch. It's better to leave a one-inch gap of space between the mulch and the stem or trunk of the plant.

How do I water Green Pillar Boxwoods?

How do I water Green Pillar Boxwoods?

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Green Pillar Boxwood a good, deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example, a one gallon pot would be watered until you count to 5; a three gallon pot would be 15; and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks. Gator bag Jr. can be used to help aid in this process and also provide plants with a good soaking due to the slow release of the water into the root-zone of the plant. Soaker Hoses can also be used to water when planting a long hedge.
