Watering weeds

Take a look at your landscape. It looks peaceful and serene, doesn’t it? The truth is, it ‘ s a battlefield. Each plant is fighting its neighbor for food, water and sunlight. Weeds, in particular, are survivors. Unlike many garden and landscape plants, weeds often thrive in any soil, with minimal water and limited food. They grow fast, shading out desirable plants, stealing water and nutrients as they grow. They tend to go to seed faster than everything else. Generally, weeds take away from the overall appearance and performance of a landscape.

So, what are weeds? Very often, weeds are the plants that survive after we try to kill them. They seem to thrive everywhere and they provide no benefit in the form of food or beauty. They can also create fire hazards that threaten life and property.

Sustainable Weed Control

Many people use herbicides to rid their yard of weeds because it is fast and easy. This is a short term view. Regularly applying herbicides to the same area can develop resistant varieties. This means the next weed generation cannot be killed with the same herbicide. Sooner or later, you will run out of herbicides to choose from. Herbicides can also threaten your landscape and garden plants through run-off and wind distribution. If chemical herbicides are used to eliminate weeds, it is extremely important that the correct herbicide is used, and that package directions are followed exactly.

Most weeds can be controlled by hand weeding, good garden design, mulching, and keeping garden plants healthy enough to defend themselves. A 4” layer of mulch can significantly reduce the number of weeds. Mulch also stabilizes soil temperature and reduces evaporation of irrigation water.

Good garden design incorporates proper site preparation for each plant, choosing plants suited to the Morgan Hill climate, and installing “smart” irrigation. In areas without plantings, porous ground covers, such as permeable pavers, can allow the soil below to breath and receive rain water. These practices work together to reduce weeds and to conserve water.

Smart Irrigation

Watering a garden or landscape is necessary to keep it healthy. Smart irrigation means improving watering efficiency and distribution to ensure the water goes where it is needed and not to the weeds. Drip irrigation, “smart” irrigation controllers and rotor heads, and soaker hoses can significantly reduce water waste. Plants that use a lot of water during the summer, such as roses, can be watered with plastic jugs buried in the ground. Simply cut the bottom off a 1-liter plastic bottle. Dig a hole a little deeper than the bottle and fill the bottom 1-2” of the hole with gravel or rocks. Place the bottle so that only the small opening on top is above the soil line. When it is time to water, use a hose to fill the bottle. This prevents watering weeds and it gets the water to the root system, where it will provide the most benefit.

If a system is already in place, be sure to check for leaks. A leaky sprinkler system can drown precious plants, help weeds to thrive, and can even kill sections of soil. Putting water where it will do the most good, in a way that reduces evaporation and run-off, will ensure that Morgan Hill gardens will have the water they need.

Water the Flowers, Not the Weeds

Select wisdom from sources old and new

If you’re out watering your flower garden by hand, you naturally concentrate the flow of water to benefit your beautiful flowers. If there’s an area of weeds, you don’t waste water there. As best you can, you avoid watering the weeds.

It’s the same with your consciousness. You can learn to selectively water the positive seeds and flowers in you by attending to them. There are enough weeds. You don’t have to encourage them.

To encourage beneficial mental states, seek experiences that stimulate them and avoid unnecessary experiences that encourage harmful ones. When you encounter something positive and healing, pause with it, lighting the lamp of your mindfulness to savor and appreciate it. If you notice the wonderful smell of the rain, for example, instead of just moving quickly past the experience without deeply appreciating it, you can prolong your contact with this wonderful sensation. Pause for a moment and really let yourself experience the smell of the rain. If you are struck by the blueness of the sky, linger for a moment and breathe mindfully, taking in the wonderful blue color. Don’t rush past these marvelous experiences, treating them as if they are unimportant. To treat them as unimportant is ultimately to treat yourself as unimportant. This is your life: enjoy it!

Sometimes we unwittingly water the weeds within us. We voluntarily expose ourselves to toxic and destructive things. When we’re sad, we tend to feed the sadness by playing sad music, drinking too much, and rehearsing our sad thoughts internally and to anyone who can bear listening to us.

Protect yourself from experiences that harm your consciousness. . . . It’s important to notice how things actually affect you and not let them colonize your consciousness, even if they’re popular or critics say they’re artistic. If you see this clearly, you won’t want to continue exposing yourself to this kind of experience. There are many lovely things in the world. Why focus so much on the potentially destructive ones?

When you're watering the garden, you natually focus on watering the flowers, not the weeds. In the same way, we can focus on cultivating beneficial mental states in our Buddhist practice, while avoiding unnecessary harmful mind states.
