Growing Plants for Kids tips

What Do Plants Need to Grow?

Plants have five basic needs. They can all be found in the acronym “LAWNS” which can make it easier for kids to remember. This acronym came from in their plant needs lesson for young kids.

Here’s what each letter of LAWNS stands for:

  • L – Light
  • A – Air
  • W – Water
  • N – Nutrients
  • S – Space


Plants need sunlight and the heat that comes from the sun to grow and thrive, just like humans need warmth. The temperature matters as well, which is why some plants will only grow at certain times of the year. Some need the summer light and heat, which others are better suited for cooler seasons. This can be a great introduction to photosynthesis!


Just like we must have oxygen to breathe and live, plants need carbon dioxide for energy. This is another factor of photosynthesis.


Water is a necessary part of plant lives in many ways, just as it is for humans. For plants, water helps move nutrients throughout the different parts, including from the soil through the roots out to each petal and leaf. Water is also important for photosynthesis, and it helps keep your crops from wilting in the warm weather.


Plants need a number of nutrients to grow and thrive properly. They take some of these nutrients from the sunlight and water, and others from the soil they are planted in. These nutrients include nitrogen, potassium, phosphorus, calcium, and magnesium.


Every plant needs room to grow. Some plants roots take up more room than others, so it’s important you know about the plants you are growing. Make sure there is sufficient space for the roots, stems, and leaves to grow. Crowded plants will struggle as they fight for their basic needs of sunlight and air.

Choosing Plants for Kids

Choosing the Right Plants for Kids to Grow

Kids will be most excited about gardening when they can choose which plants to go. However, it’s also important that you steer them in the right direction of which plants to choose based on the following factors.

Germinate Quickly

You want to choose plants that will germinate quickly – meaning the seed will turn into a sprout and shoot up from the soil fast. Some plants are slow at this, and that may cause your children to lose interest. When they are just beginning, choosing plants with a quick germination rate will keep their attention spans.

Bonus Tip! Your children can help speed up the process of germination by using scarification. This is an easy process of lightly scrubbing the seeds with sandpaper, then placing them in a jar of water the night before planting. This helps with water absorption and speeds the process of the sprout forming.

Produce a Crop Quickly

Not only do the kids want to see sprouts coming from the dirt, they want to see the end product as soon as possible. Whether it’s a flower or a vegetable, choose seedlings that will soon give your children the reward they are working for.

Very Low Maintenance

When starting out, your children need to be responsible for plants that only require watering and feeding. You want to start them off small and you can work your way up to more high-maintenance plants as your children get older and want the challenge.
