Common name: Juniper

Juniper communis - common juniper is a shrubby bush / tree that makes a useful plant for planting along a boundary and areas lacking good soil quality and depth.

Similarly they will tolerate both alkaline and acid soils.

The common varieties can grow to around 3m (10ft) high with a 2m (6ft) spread.

Dwarf varieties are available and these grow to around 600mm (2ft) high with a 300mm(1ft) spread.

Prostrate varieties will grow to around 300mm (1ft) high and spread to around 2m (6ft)

Juniper Boundary

Varieties come in various shades of green.

Although they are suited to partial shade, a general rule would be, the lighter the foliage colour / shade the more sunshine it needs.


As a general rule no pruning is required, however light trimming may be required to maintain a desired shape.

This should be done after the juvenile (new) growth has established circa Week 26

The tree/shrub should never be trimmed back to such a stage that this action exposes the brown mature wood within the structure of the tree/shrub

Junipers will not produce new growth from this mature wood meaning, there will always be an unsightly brown patch at the point/s of cutting back.

Typical examples of over pruned trees


Week 18-20:

If ground conditions all plant out 600-900mm (2ft-3ft) tall seedlings in their final quarters.

circa week 40:

Collect ripe berries and extract the seeds from them then sow them immediately into a pot/tray filled with seed compost.

Place the pot/tray in a cold frame to germinate.

Once germinated pot up the seedlings into 75mm(3") pots of potting compost and grow on in the coldframe.

Alternatively prick them out into a sheltered nursery bed and grow them on.

Seedling will take one or two years to reach a size suitable for planting out in their final quarters.

Coloured and named varieties can also be propagated around now from cuttings!

Take heel cuttings and insert them into pots of gritty compost and place the container/s in a coldframe to root.

Once rooted pot the cuttings up into 75mm(3") pots of compost and treat as described for seedlings.
