More often than not, gardeners are more worried about getting enough water to their plants than they are about over watering. The scorching sun tends to zap them of moisture, and hence you need a lot of moisture to replace the evaporating nutrients. Hence, humidity seems to be a good ally for this right?
Wrong. Some can’t handle excessive amounts of water. Here are two common ones that suffer under humid and hot environments.
Tomatoes can suffer from too much water. Their constitutions can only handle so much moisture before they begin to rupture, exposing them to the outside world. The cells of the plant have a limit to how much water they can use to grow. If that limit is exceeded, the skin tends to split. The tomato uses its skin to keep away disease and pests, like our bodies. When that skin splits, the tomato is exposed to all kinds of problems that could keep it from developing further. Even if a disease doesn’t manage to make its way to the tomato, the mold spores will. Keep tomatoes in a controlled environment, being careful to not overexpose them to moisture and not to let them dry out either.
Cucumbers can come to harm in particularly wet climates. Recent rains often bring powdery mildew into the picture that stunts the growth of your plant. In addition to the powdery strain, moisture also brings downy mildew and pests like pickle worm. Downy mildew spreads across the surface; turning leaves brown and devouring them. Pickle worms like to bore into cucumbers and hatch. Once out, they begin eating the cucumber from the inside, out. To identify whether or not one of these worms has penetrated your cucumber, look for holes and signs of movement inside. Chuck the infested ones as they’re bad.
With tomatoes and cucumbers, you need to carefully monitor the health of your plants. Don’t expose it to too much water, but be sure to give it enough water every day. There’s a careful balance that may take a few tries to get the hang of when growing these vegetables in a humid garden.
