Many of those who have tried gardening in the region can tell you that Colorado garden soil has a few definite problems. Because of the dry climate in Colorado and the great differences in temperature between summer and winter, many homeowners run into obstacles that require them having to water more, use expensive fertilizer or even buy additional soil to try to create a better consistency of the soil that they were previously trying to use.
The top compost soil that most gardeners might use in Colorado tends to drain more during the summer and leave plants dry even after you’ve watered them consistently. The same can happen with most types of lawn as well, and the added heat evaporating the water that’s left near the surface definitely doesn’t help either.
Another common problem is that those homeowners who try to do gardening without bringing in new soil will usually hit clay when they try to dig too deep. This factor creates the opposite problem, as clay is very bad at draining water, so the roots of your plants could suffer as a result of this as well.
The general consensus is that the soil has to be balanced not only in terms of its pH, but more importantly to make it as consistent and cohesive as possible without retaining or draining too much of the water you add to it, while also factoring in the effects that the dry climate of Colorado can have on the soil in the long run.
