Here are some tips for growing bigger plants:
Feed your plants. Roots need nutrients. Add compost, fertilizer, or other organic matter to the soil to give them what they need. Compost also helps to improve the structure of the soil and allows for better water drainage.
Water your plants properly. Roots need water, but not too much. Water your plants deeply once a week, rather than giving them a little water every day. This method will encourage the roots to grow deep into the soil.
Give your plants room to grow. The roots need space to spread out. If your plants are in containers, make sure they are not overcrowded. As your plants grow, they may need to be moved to larger containers or given more space in the garden.
Avoid root damage. Be careful not to damage the roots when planting or transplanting your plants. When you are cultivating your garden, be careful not to go too deeply and disturb the root systems.
By following these tips, you can help your plants grow big and healthy.
