Growing the Burkii Juniper
Size and Appearance
The Burkii Juniper is a slender, upright evergreen with a moderate growth rate that typically grows 10 to 15 feet tall, with a conical form. Mature trees are usually no more than 6 or 7 feet wide. Over time it may grow a little taller and wider. The branches are closely spaced around the trunk, keeping this bush dense even if you never trim it. Well-branched and bushy to the ground unless pruned up, older trees develop a low trunk, with a broad, flaring base with deep fluting. The peeling, reddish-brown bark gives a rugged look to mature trees, and you can trim it up to show off the trunk and make a more tree-like form.
The leaves of this tree are very small, and shaped like pointed triangles, with their bases wrapped around the stems, giving a fluffy look, and they are not particularly prickly. They are variable in color, bluish green when newly emerged in spring, becoming more silvery-blue in summer and into fall. Cold weather turns the leaves an attractive plum purple, overcast with gray. This is a male tree, so it does not produce any juniper berries.
Using Burkii Juniper in Your Garden
As a specimen or a screen, the Burkii Juniper is hard to beat. It has a rugged beauty that projects its toughness, and on a lawn – alone or in a group of three – it looks great. Place it in beds as a vertical accent, or at the corners to frame them. Plant a row along a fence or driveway or use it as a relatively slender screen along your property line. Plant it on slopes and banks, as well as among rocks, gravel and boulders. It could even be grown for many years in a large tub or planter, as a patio specimen.
Hardiness
The Burkii Juniper is incredibly hardy. It thrives all across the country, from cold states and high ground in zone 2, all the way into northern Florida, southern California and Texas, in zone 9. Don’t even think about whether it will grow where you are – it will.
Sun Exposure and Soil Conditions
Full sun is best for the Burkii Juniper, but it will tolerate a few hours of shade in a day. It grows in almost any type of soil, and it is remarkable for growing well in moist soils as well as in rocky ground and very dry places. It even grows in heavy clay, as long as it is not low-lying and always wet. Avoid any spots that are often wet, and too shady, and this tree will be happy. It will even grow near the notorious black walnut, which poisons the soil around it, preventing most plants from growing – but not this one.
Maintenance and Pruning
The Burkii Juniper is naturally dense and well-shaped, but you can trim it to give it formal beauty if you wish. It clips well into a tear-drop shape, or a narrower column, if trimmed once or twice a year. Clip in spring, once the new growth has matured a little, and again in late summer if you wish. You can prune up the lower branches to develop a more tree-like form and show off its attractive trunk and bark. Deer don’t bother it, and there are few diseases or pests or any great importance. Salt and urban pollution don’t bother it either. Avoid planting around apple trees, as it can spread apple rust, a leaf disease, which affects apples, while having no serious effect on junipers.
