Description

This is the spiral topiary form of the Dwarf Alberta Spruce, Picea glauca ‘Conica’. Because it’s so slow growing (2 to 4 inches per year) it requires very little maintenance to maintain its spiral form. all live spiral topiary plants. One light trimming per year is all that’s needed. The shape and the bright blue-green needles densely packed along the branches add year round interest to any garden bed or container. Use one as a focal point specimen or accent tree in small spaces, two to frame an entryway or three in a grouping where space allows.

Landscape & Garden Uses

The Spiral Dwarf Alberta Spruce is most useful as a focal point specimen, in groupings, or to accentuate or frame an entryway. Its smaller size and slow rate of growth lends well to smaller garden spaces and container gardens. A fine addition to conifer gardens, formal gardens and topiary gardens.

Suggested Spacing: 5 feet apart for space between plants

Growing Preferences

The Dwarf Alberta Spruce is easy to grow in most any moist but well-drained soil of average fertility and a pH ranging between 6.0 and 7.5 on the pH scale. As with so many other conifers, constantly soggy or wet soils can be problematic; leading to root rot or other harmful plant diseases. So make sure to plant this one in well-drained soil, whether in the ground or in pots. It is quite drought tolerant when established. In pots, soil moisture will need to be monitored more closely, especially during summer. When the top two inches of soil is dry provide water. When planting in containers, choose a container with a drainage hole(s) and use a quality potting soil or potting mix, or a 50/50 mix thereof. To prevent roots and soil matter from stopping up the drainage holes it’s a good idea to line the interior of the pot with a porous landscape fabric. It grows best in full sun however in Zones 7b and 8a in the hot south it will prefer some shade or filtered sun during the middle of the afternoon.

Note: In Zones 7b and 8a the Alberta Spruce does better in the ground than in pots so that its roots are not exposed to the hot air temperatures and would also prefer some shade or filtered sun in the afternoon hours.

Average Trimmings Per Year: One trimming annually after new growth has fully emerged in spring. At this time the new growth can be trimmed back by half its length.

Plants arrived on time and in excellent condition. The only minor negative is that the photo of the specimen shows a taper bottom to top, but the plants were smoothly trimmed bottom to top. This is our first time ordering from Wilson, based on this experience, we would recommend this company.———————————–We are so glad you are pleased with your purchase! Thanks for the great review!

I was skeptical to buy trees online because I was worried about the shipment and the trees arriving damaged and dried out. But they arrived in 2 days, perfectly packaged with the soil still moist. They were in excellent shape, with not one branch broken. They came with planting and caring instructions. They are now planted in our yard and looking great! Service is also amazing. I will definitely buy there again!!! ——– WBG Reply: Hi Carole – Thanks so much for taking the to provide your review and for all the compliments. We’re so glad you chose us and that we had the opportunity to serve you. Sometimes first-time online plant buyers are turned off after their first purchase because they opened the box to find out they paid a whole lot of money for what was a tiny and/or half-dead plant.
