Plants sometimes need an extra boost to strengthen or establish their root systems. Whether starting from seed or supporting a growing plant, you need that foundation to provide structure and pull in water and nutrients. Most plants are also unlikely to grow above their base or crown roots without a deeper, stronger system below. When that structure is severed by transplanting or unearthing, plants quickly weaken and become susceptible to diseases like root rot. Although applying the right balance of fertilizer and water can help with recovery from such a shock, the wrong amount can easily cause fatal problems. However, when disaster strikes, applying root stimulators and other enhancements can help rejuvenate your soil and the plants that rely on it. Fundamentally, the best approach to developing more robust roots is creating a clear plan for soil and plant care that is grounded in cultivating a healthy below-ground environment.
