Many people have used old tires in gardens as raised beds, planters, tree rings, and DIY decor. However, these uses are not recommended due to the toxicity of many of the chemicals used to manufacture tires. These chemicals can leach into the soil and water as the tire breaks down, creating environmental pollution and health hazards for gardeners and their families.

There are two main times of year to apply mulch: mid to late spring and late fall. Spreading mulch in mid to late spring helps protect new seedlings as the soil warms up. It's best to wait until temperatures are steady, as mulching too early in the spring can slow down the soil's warming process and hinder plant growth. Fall mulching is also beneficial, as it insulates the soil and helps regulate its temperature when the first frosts arrive.

Yes, it is possible to add too little mulch. Anything less than 1 inch will likely result in too little coverage around your plants, allowing weeds to grow through and minimizing the positive effects that a deeper bed of mulch would have, like maintaining proper soil moisture and insulating the ground.

Grass is the most popular and safest option for planting over a septic drain field, but you can also plant small flowering plants and other lightweight plants that don’t have woody or deep roots. Avoid trees and bushes within 10 feet of the field, as the woody roots can crack the perforated pipes. You should also avoid planting vegetable or fruit gardens over your drain field, as a leak from the pipes could contaminate the soil and put anyone who eats the produce at risk.
