Light, Water, and Nutrients Required for Mature Plants

In previous articles, we looked at light, water, and nutrients as separate fields to discuss in depth. Here, we are going to lump them together for one simple reason. Every mature plant is different. There's no one-size-fits-all strategy here, but plenty of little notes to consider while growing. It will be best for you to do some individualized research into your plants and make sure there aren't any unusual requirements.

How Much Light Do My Mature Plants Need?

Tomatoes, beans, corn, and squash are a few examples of plants that enjoy plenty of light. Most of the vegetables we consume today enjoy full sun because they once acted as annual weeds covering disturbed soil. There are plenty of edibles that can survive in partial sun. Nevertheless, your most common are going to fall into the former category. Rise has delved into breaking down sun requirements if you're unsure what the differences are.

Remember, the light source your plants now use also carries with it some other effects. If your plants are sensitive to heat but still need full sun, consider plant in a place shaded from the warm afternoon sun. Find a place that receives early morning light from the east but is protected by shade from a tree or home. Planting at the edge of a water source adds a little extra reflected light to your garden. It also acts as a heatsink, absorbing thermal radiation all day and radiating it slowly at night.

How Much Water Do My Mature Plants Need?

Some plants enjoy plenty of water, while others can withstand some time without it. When you first transplant into the garden, be sure to water immediately. The plants will struggle initially after transplanting but just observe it. Ensure the soil around your plants never becomes so dried out that the plant wilts.

Some stress in the garden is normal and entices the plant to dig its roots deeper into the ground. Deeper roots mean a better chance of acquiring more water and nutrients. But, prolonged drought conditions can weaken the plant and make it more susceptible to pests. It is a delicate balance and takes some time to notice when it is the right time to water, but don't worry. Over time you learn to anticipate when your plants will need water just by walking the garden.

The water a plant needs is dependant on both the plant and your garden situation. If you're planting in pots, add water slowly and evenly over the top of the container. Aim to stop as you see it begin to trickle out of the bottom. Too much too fast can cause water to quickly go through dry soil, not fully saturating it, or potentially leaching out water-soluble nutrients. If you plan to grow in the ground or a large planter, consider providing enough water to maintain the plant.

Mel Bartholomew, the creator of Square Foot Gardening, recommends using less water, more often. He proposes one cup of sun-warmed water applied to the base of seedlings (multiple helpings for mature plants) near the stem when it looks thirsty. I agree with him in saying that the best way to know when to water the plants is to watch them. Walk your garden daily. If you notice a plant is drooping, give it some water.
