From our perspective, our hydration needs are intrinsically linked to our Mediterranean origins. We thrive in consistently moist soil, a condition that mimics the damp, well-draining banks of our native habitat. However, the term "moist" is crucial and is often misinterpreted. We do not wish to sit in waterlogged, soggy soil, as this suffocates our roots, leading to rot and a swift decline. Conversely, we also suffer greatly if our soil is allowed to become bone dry. Our leaves will wilt, become crisp, and lose their vibrant flavor and aroma. The goal is a stable, slightly damp environment for our root system.
The most reliable method to determine if we need water is to physically check the soil. Do not rely on a fixed schedule, as conditions change constantly. We ask that you insert your finger into the soil up to the first knuckle (about an inch deep). If the soil at that depth feels dry to the touch, it is time to provide us with a thorough drink. If it still feels cool and moist, please wait and check again in a day or two. This simple tactile test is the most accurate way to understand our immediate needs and prevents both over and under-watering.
Our thirst is not constant; it is influenced by several environmental factors. During the active growing season (spring and summer), with longer daylight hours and warmer temperatures, we will require water more frequently—potentially every few days. In the dormant winter months, our growth slows, and evaporation decreases, meaning we will need water less often, perhaps only once every week or two. Furthermore, the size of our pot, the type of soil we are in (well-draining is best), the amount of light we receive, and the humidity of the room all play significant roles. A mint plant in a terracotta pot in a sunny, warm window will dry out far faster than one in a plastic pot in a cooler, shadier spot.
When it is time to water, please do so properly. A light sprinkling on the surface only encourages our roots to grow shallowly, making us more vulnerable to drought. Instead, water us slowly and deeply at the base until you see excess water begin to flow freely from the drainage holes at the bottom of the pot. This ensures the entire root ball is adequately hydrated. It is absolutely essential that our container has these drainage holes. After watering, always empty the saucer or cache pot beneath us after about 15 minutes. We must never be left standing in a pool of water.
Learn to read our signals. If you have over-watered us, our lower leaves will turn yellow and may drop off. The stems might become soft and blackened, and the soil will have a persistently wet smell. If you suspect this, hold off on watering immediately and ensure we have excellent air circulation. If you have under-watered us, our entire structure will wilt dramatically, and the leaves will become dry and brittle. Thankfully, we are resilient; a good, deep drink will often perk us up within hours if the under-watering was not too severe.
