How To Grow A Holly Bush
Before you go ahead and plant your holly bush, you can make sure most of its needs are met by considering the following:
When to Plant a Holly Bush
Holly bushes are best planted throughout the milder months of spring so as to avoid intense heat or cold.

How to Plant a Holly Bush
To plant your holly bush plants, dig a hole that is about three times wider than the root ball but not quite as deep. Be sure to gently remove the plant from its container and tease out the roots if you are planting the bush in a pot. Mix your compost into the planting hole and if your soil is pH neutral or alkaline, add some bark or wood chips to increase acidity. Once the plant is in the hole, fill it with damp soil at the base then add about three inches of organic mulch to make sure it stays moist.
How to Care for Holly Bush
One of the great things about holly bushes is that they’re very easy to care for once they’re established. Ensure that you fertilize your bushes at least once a year using a balanced fertilizer. In normal circumstances, holly bushes don’t need to be watered but if in a drought, give them about five centimetres of water every week.
Mulching around the base of the shrub will help the bush retain water in the summertime and even out the temperature of the soil in the winter months.
If it seems as though the shrubs are being damaged by the elements of winter, you can wrap them in burlap to protect them from the weather.
When To Trim Your Holly Bush
To properly care for your holly shrubs, you will need to prune it fairly regularly. By pruning your holly bushes, you can ensure they keep a nice, compact form instead of becoming leggy and scraggly.
If you prefer a smaller shrub then you can trim your holly bush at any time, although the best time is mid to late April.

Killing a holly bush can be done with a little bit of effort, should you need to rid your garden of it for any particular reason.
Make sure you start killing your holly bush off in the cooler months when the shrub’s nutrients are pulled into its root system. Begin by pruning the shrub as close to the ground as possible. Then, hammer a copper spike into the middle of the trunk. These spikes can be bought at hardware stores and are typically used to hammer down copper roofing.
Next, cover your holly bush’s stump with an opaque tarp as this will help deprive it of sunlight. If you so wish, you can also pour bleach onto the stump and around the roots for a few days. However, this could harm any other soil and plants around your holly bush.
