From VOA Learning English, this is the Health & Lifestyle Report.
For half the world, spring has begun. Temperatures are warming and daylight lasts longer. People who like to garden may be ready to get their hands dirty and start clearing the ground for new plantings. But garden experts warn -- not too fast.
Jessica Damiano is one such expert. She says that removing plant matter too early can disturb important insects not ready for the cool early spring temperatures.
In the fall, Damiano explains, she skips cleanup. She lets plant matter remain on the ground. It serves as shelter for insects over winter.
In early spring, those insects are still sleeping. Removing the plant matter before the insects begin their life cycles would mean removing them from your garden. Fewer insects mean less food for birds and fewer flowers and vegetables for the gardener.
Damiano says experts do not all agree on the best time to start cleaning the ground and garden area in the spring. But they usually agree to wait until the temperatures are regularly above 10 degrees Celsius. That is when sleeping insects “wake up.” Some experts define “regularly” as at least five days in a row. Damiano says she usually waits seven nights.
However, even then, she says to keep the plant matter on the ground for another week or so before removing it from your property. This gives any insects that are still “sleeping” enough time to wake up.
Early cleaning of a garden is often followed by early mulching. Applying mulch makes the garden look neat and clean. But Damiano reminds us that soil and plants are not just for show. They are part of a living ecosystem.
Mulch is an important part of a healthy garden. It keeps soil wet, limits the growth of weeds, and helps keep soil temperatures even. But timing is important.
Mulching before the soil has warmed enough will keep in the cold and slow the reawakening of the plants. This can also limit their growth. And if the soil is wet, early mulching can lead to mold, mildew, and fungal diseases.
Before applying mulch, wait until it is safe to plant annuals and warm-season vegetables in your area. For Damiano in New York state, that means waiting until the end of May.
Timing is also important for fertilizing.
For grasses, Damiano says not to fertilize until mid to late spring. At this time, grass has left dormancy and begins active growth.
Fertilizing too early will not help grasses grow. In fact, it can hurt the grass.
Grasses that are fertilized in early spring cannot fully make use of those nutrients in the fertilizer. They may start growing when they should be spending their energy on root development. Strong roots are necessary to help grasses survive hot summer weather.
Also, fertilizer that cannot be used by a dormant or partly dormant plant threatens the environment as it goes through soil and into groundwater. For that reason, in parts of the United States, people are not permitted to fertilizer too early.
And because it does not help the grass, fertilizing too early is simply a waste of money.
What about early blooming flowers?
Tulips and daffodils are two early blooming flowers. After they or any spring bulb has bloomed, the leaves continue to produce energy for the following year’s bulb. Damiano says it okay to remove stems. But she says to remove the leaves only after they have turned yellow.
For those who do not want to wait to garden, Damiano does have an early spring task. Now is a good time to repot houseplants.
Move them into the next-size pot — no more than 5 centimeters wider than their current container. And give them a bit of fertilizer. As the season’s longer days cause them to restart active growth, this extra nutrition will help.
