Prof. Samuel Fitzgerald, Ph.D.By avoiding common mistakes with soil and its characteristics, roses can prevent unnecessary stress and even death. During my years of trial and error in my own garden, I learned about significant mistakes that will damage rose health. These mistakes will create problems that lead to unnecessary stress and, simply, growth and bloom issues. If you recognize mistakes early, you can avoid long-term trouble for your roses.
Unamended Soils
- Pure clay suffocates roots and causes rot
- Pure sand lacks nutrients and dries too fast
- No soil structure for root expansion
- Requires immediate corrective amendments
pH Mismanagement
- Over-liming creates alkaline lockout
- Excess sulfur makes toxic acidity
- Blind adjustment without testing
- Causes nutrient deficiencies rapidly
Physical Damage
- Compacting soil during planting
- Walking on root zones compresses earth
- Heavy equipment destroys soil structure
- Reduces oxygen flow to roots critically
Extreme soils that are not modified will lead to immediate failure. Roses that are planted in pure clay soil are like growing them in concrete. Pure sand drains too quickly to keep them alive. Always amend these soils before planting. I mix clay with 40% compost and 20% expanded shale. This creates the crumbly texture that roses want and need.
pH surmising leads to invisible calamity. Adding lime or sulfur without testing the results invariably exacerbates the problem. Testing the soil before making any adjustments is imperative. Even small errors in pH can result in locking up nutrients. Test the soil twice a year with reliable kits and make slight adjustments over the course of one or two weeks.
Physical compression surrounding roots can be extremely detrimental. Walking near new plants compresses the soil. Even excessive tamping during planting can suffocate the roots. Always backfill and plant without packing the earth. A light basin will always be better than filling the earth. Proper aeration will allow your roses to establish faster than if you pack it down.
Seasonal neglect can lead to a decline in soil health over time. Roses will continuously draw nutrients from the soil, even when they are dormant, and it is essential to replenish the soil each spring with 2 inches of compost. Please feed container roses monthly during growth. The first warning sign of soil health in roses is a period of slow growth. Overall, many soil-related problems can be prevented with consistent maintenance.
