When is the best time to plant?

The best time to plant would be on a cooler day with overcast sky and no wind. Typically, the times of year that have these conditions would be spring and fall. But planting can be done all season if they are properly watered after planting while the roots establish. If planting on a hot day soak in the plants before planting and water well right after planting. Do not let the exposed roots dry out during the planting process.

We supply our products to various Greenhouses. One location is Aspen Crossing, located southeast of Calgary just before Mossleigh, AB. Please note that selection varies between garden centre and on-line.  The biggest selection is right where you are!

Please water your plants upon arrival. Once planted, ensure they get the correct amount of water. Roots must remain somewhat moist, but not wet between watering. Depending on wind, heat, or growth rate watering may be required daily in the first year until plants are established.

Please ensure you select your products carefully, as we will not exchange or refund products that have been incorrectly ordered.

Do you ship to other parts of Canada or the US?

Currently, we are only shipping to Calgary and Area. Costs to ship to other regions can be quite expensive, we cannot ship to the US or other countries as these are live plants and would be subject to expensive and time-consuming inspections.

How big are you potted deciduous (leafy) trees?

This is a basic guideline for our tree pot sizes and may vary depending on variety. The following is for deciduous (leafy) trees. A 5 gallon tree, they are typically 4-6 feet tall, 7 gallon trees are typically 5-7 feet tall, 10 gallon trees are 6-10 feet tall and 15 gallon trees are 9-12 feet tall. 

How big are your potted conifer (evergreen) trees?

This is a basic guideline for your evergreen pot sizes and may vary depending on variety. The following is for conifer (evergreen) trees. A 1 gallon tree would be 12-18” tall, a 2 gallon would be 18” to 30” tall, a 5 gallon would be 2-3 feet tall, a 10 gallon would be 4-5 feet tall and a 15 gallon would be 5-6 feet tall.

How do I plant my new shrubs, trees or evergreens?

For the size of the hole it is recommended to dig the hole 1.5-2x the diameter of the pot and 1x the depth. For example, if the diameter of the pot is 8" and the depth is 10" I would dig the hole 12" wide and around 10" deep. If you are planting trees then width can be much wider to establish a strong root system. Another thing to remember is to keep the black top soil from the top of the hole and remove all the clay (grayish soil below) and replace the clay with the black top soil and mix in some compost/manure with some good quality black soil. Please ensure that the top of the root ball is at the level of the top of the soil, if these are planted deeper than the original height this can severely stunt the plant or even kill it. Another good thing to do is to use a root booster such as Plant-Prod Ultimate Root Booster 5-15-5 fertilizer. I would recommend this for the first month after you plant it and you can then use an all-purpose fertilizer thereafter. As the plants are establishing (rooting into the ground) it is very important to keep the trees quite moist as they will dry out quickly until roots are established. On hot days after planting they should be watered daily for the first 2-3 weeks. After this then check the soil and water as needed, do not let them dry out.  Another thing that helps to prevent it from drying out is using about 2" layer of mulch on top of the ground but don't bury your plants in mulch especially around the trunk of the trees. To help trees overwinter better it is recommended to water them in heavily in late fall right before the winter weather hits. This helps the tree survive the warming periods of a Chinook as it keeps the roots frozen in and prevents them from thinking it is spring.

How do I grow Roses?

Roses prefer a sunny well drained location, do not plant in spot where water drains over it or it sits in water. They like black top soil mixed with an all-purpose potting mix to promote better drainage. As the rose is flowering remember to remove the spent blooms to ensure more flowers, this is done by pruning right below the flower. For newly Transplanted Roses use Plant Prod Ultimate Root Booster fertilizer to help promote a strong root system. Then you can switch to Plant Prod 28-14-14 Rose fertilizer every 2-4 weeks during the growing season and again in spring once new growth appears.

What are cold hardiness zones?

Cold hardiness zones for plants tells you what is the coldest temperature the plants can handle when planted in the ground. Lower zone numbers handle colder climates and ones with higher numbers are for warmer climates. Calgary and area is rated as Zone 4 with a temperature rating of -31 to -37 degrees Celsius. Another thing to consider when planting in Calgary is Chinook winds which can harm certain plants planted in the wrong locations even though they have a Zone 3 or 4 rating.

I have received my plants but I don't have time to plant them yet, what should I do?

They can stay in the pots for a while but you must remember they will dry out a lot quicker above ground and will need water daily, even on rainy or cloudy days. It is a good idea to keep them in a partly shady protected location until you get them planted.

Should I stake my trees?

Staking is only really required if the tree starts bending or is being blown out of its spot due to high winds. These trees should not require staking and I would recommend if the wind is blowing over a bit to straighten them out and pack in the soil more around the roots until it is established. This will make a stronger tree in the end.
