Best time to plant pyracantha?

Asked September 14, 2015, 2:02 PM EDT

We bought 4 pyracantha plants in 3.5 gallon containers that will need to be replanted in the back yard. The soil is caliche like and will require a get deal of effort to dig the holes. When is the best time to put these in the ground (it is now mid September)? Also, the plants are about 5' H by 2' W. Are the containers big enough if we hold off planting? Any planting tips for this soil type?

It is important that you test the soil for drainage before you plant anything. Moisten the soil before beginning to dig and then fill the hole with water. The water should completely drain within a few hours, if it does not you should not plant any plants until you can see water will drain easily.
Fall is idea for planting, so plant the pyracanthas in the next two months would be great.
Here is an exert out of one of out proper planting fact sheets I wrote to help you:

Planting your tree Container-grown trees should be removed from their containers, and large circling roots gently pulled out and away from the root ball.
This stimulates the roots and encourages them to grow outward into the native soil instead of circling around the planting hole. Score the sides of the root ball before planting to reduce the impermeable interface between the root ball and the sides of the planting hole.
Backfilling – Once the tree is in place, gently position it so the root flare will be visible above the soil line after planting. Backfill the planting hole with the native soil that was removed when the hole was dug. Remove large rocks or debris before backfilling. It is not necessary or advisable to add fertilizers at this time.
Soil amendments such as compost, aged manure or peat moss are best blended
into the top 8 to 12 inches of backfill; the most active root growth will occur in this area. Amendments should not exceed 20 percent of the fill material. It is important to create a natural soil rooting environment free of excessive additives. A common mistake is making the planting hole too rich. This discourages root growth into the native soil and creates a “virtual pot” in the ground. As you add soil back into the planting hole, tamp the soil lightly to remove air pockets.
For all types of trees, once the hole is filled, build a berm as wide as the planting hole around the tree. This will create a basin you can then fill with water to ensure the entire root ball recieves moisture.
