Planting bare root shrubs

Planting a bare root shrub

While it is still a bit early in March to risk putting tender plants out into the garden, it is actually the perfect window for planting woody shrubs. Getting these plants into the ground now allows the root systems to establish themselves comfortably before the coming explosion of spring foliage begins to demand all of their energy. This timing is particularly vital for bare-root plants, which need that extra head start to anchor themselves in before the soil dries out in the summer.

Since these shrubs are intended to be permanent fixtures in your garden for years to come, it is worth the  extra effort during the planting stage. Start by ensuring the area is completely clear of any perennial weeds. When you’re ready to dig, aim for a hole that is wide and about nine inches deep. It’s helpful to loosen the subsoil at the bottom to help the roots penetrate, but resist the urge to add any compost or soil improvers directly into the hole.

For a little extra help with establishment, I like to dust the roots with mycorrhizal fungi before planting. When you set the plant into the hole, try to position it slightly “proud,” meaning it sits just a fraction higher than the surrounding soil level. As you backfill, firm the soil around the roots carefully to create a very slight cone or mound. This prevents water from pooling directly against the stem, which can cause rot.

To finish, give the new arrival a very generous watering to settle the soil around the roots. Follow this up with a thick layer of high-quality compost as mulch, being careful to keep it away from the main trunk. This keeps the moisture locked in and gives the shrub the best possible start in its new home.
