Question
Potting Soil Question
I am about to plant some Geraniums in pots I had others in last year. I dumped the soil into another container and found hundreds of little yellowish balls. When I squeezed one of them it collapsed and a watery substance came out. What are these and will they prevent me from using this potting soil again this year?
Answer
Those little yellow balls are most likely a time-release fertilizer that has not fully broken down yet. The most common is Scott's Osmocote but there are several poly or urea coated time release fertilizers on the market. To make sure your plants thrive I might mix in some good humus-rich material to make your old soil new again but other than that the soil should just fine to use.
