Planting Guides

Growing Shrubs and Small Trees:
The shrubs and trees we sell are 1-2 year-old seedlings. These young plants appreciate some extra attention during their first 3 years in your landscape.

    Preferred growing conditions:
  • Check each species soil preferences before planting. Some do well in clay while others do not.
  • Mulch with common mulching materials. As they get larger (2 ft. or more in height), thicken the mulch layer to a depth of 2-3 inches.
  • Even xeric (waterwise) species will establish better and grow more quickly when given regular irrigation during the first 3 years in the garden. As they begin to reach maturity, watering frequency can be reduced to a good deep soaking every 10 to 14 days during the heat of summer.
  • Plant in full sun or part sun depending on plant preference.
  • Dig a wide but shallow hole and enrich the soil with ample amounts of compost and Yum Yum. This will help them to grow and mature more quickly.
  • Special comments:
  • Most native shrubs and trees are highly recommended for providing wildlife habitat (nesting spots, fruit or seeds for songbirds and mammals, nectar for pollinators).
  • They are excellent for use to grow as natural (un-sheared!) hedges along fences, property lines and driveways. They live for many years once established.
  • Garden Care:
  • Fertilize in the fall with Yum Yum Mix and good quality compost. This is most important during the first 3 years in the landscape. Established plants don't need to be fertilized (unless growth is stunted by extremely poor soils).
  • Where browsing animals (rabbits, deer and others) are a problem, it is advisable to protect young plants with a wire cage. These can be removed after 3-4 years in the ground.
  • Mulching is essential to maintain the soil moisture these woody plants need to establish their deep growing roots. Be sure and replenish the mulch in fall and summer to keep it sufficiently deep.

We purchase 3 Dark Knight Blue Mist Spirea in early May 2016. When they arrived, as others have noted, they were about 2-3" tall, at most. This was surprising, however, I called High County Gardens and they explained that they intentionally prune the shrubs down to a small size from the ground up so that they are not damaged in shipping, although the root ball is more substantial so that by the end of growing season they should be anywhere from 75% to full grown. I have to admit, I was a bit skeptical, but my skepticism could not have been more off. I would guess they are about 60-70% toward full growth at this point. They are beautiful plants, and I only expect them to fill out into next Spring (2017) growing season considering their growth in their initial year.

The original plantings, as mailed, can be seen in the first photo in between the Mexican Feather grasses. As you will see, the Speria got so large, we eventually transplanted the Mexican Feather grass and left the three Speria shrubs by themselves.

We loved them so much we recently bought 4 more plants to continue lining our fence. Great product.

I ordered six of these. When they arrived they were all very small. We were doing planting of a new yard and we planted about 300+ plants from roses to trees to bulbs from other online and local nurseries. Of the six I ordered, only two survived...and just barely. All the other plants that were put in are doing well and waking up in the spring. Our order was shipped in the fall so perhaps we got left overs, Based on the survival rate and the costs I would not recommend this. You may have better luck if you order earlier.

        In a year of disappointing plants from HCG this was one that I fell good about. Many of these HCG starter shrubs have been quite small, but my two plants were tall and seemed quite vigorous. They haven't filled out much in their first season, but did put out some flowers even on their lanky stems. In a few years I expect them to look quite nice.

            In response to some of the other reviews: HCG plants may be a little small when they arrive, but given just a little compost and water until they're established, they will double even triple in size. We planted a large flower garden in southern Colorado using HCG plants (and some others from other sources) and were amazed at how much the HCG plants grew in just the first year. Blue Mist Spirea Dark Knight was one of those plants. We had 3-4 foot wide shrubs by the end of the second summer. All we added to the dirt was some compost. It's a beautiful plant.

              I had several of the blue mist plants when gardening in the Pacific Northwest. Most plants grow so well there that I took this plant for granted. Now I am gardening in Northern New Mexico, and most plants do not survive well. What does fairly well usually gets eaten by the rabbits, even rabbit resistant plants. I am impressed with how well these plants do--they help carry the garden through the heat of the summer and well into autumn.
              I will always have this plant in my yard.

              Arrived - 1 dead, and one grew for 2 weeks and then died. But I was most dismayed when they arrived and they were the tiniest shrubs known to man. I don't know if they will grow to their full maturity before I die (I'm guessing 20 years)

                      Suggested Companion Plants:

                      USDA Hardiness Planting Zones

                      To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

                      • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
                      • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
