Regularly watering your plants keeps them hydrated because the heat can quickly cause the soil to dry out. Water in the early morning or late at night to reduce evaporation
Too much direct sunlight can harm your plants, so give them enough shade by moving them to an area with filtered light or covering them with a sheer curtain.
Ensure adequate airflow in your indoor garden. To keep the air flowing and avoid stagnant conditions, use fans when it's possible to open the doors or windows to let fresh air enter the room.
Your plants might require less fertilizer in the summer than in the other seasons. Avoid over-fertilizing, as this may harm your plants.
Ensure the soil mixture in your potted plants drains properly. Consider repotting if the plant has outgrown its current container or the soil has become compacted.
