Next up, let’s explore the best watering techniques for your Thuja Green Giant!

Watering Your Thuja Green Giant

Water your Thuja Green Giant deeply once a week. Ensure the soil remains consistently moist but not waterlogged.

Watering Frequency For Thuja Trees

Thuja Green Giants need watering every other day during their first month after planting. This helps establish strong roots. After the first month, water them once a week if there is no rain.

Each evergreen tree needs about an inch of water per week.

Signs of overwatering include yellowing leaves and root rot. If the plant looks wilted or brown, it might not be getting enough water. Adjust your watering schedule based on these signs and season changes to keep your shrubs healthy and thriving all year round.

Signs of Over and Underwatering

Proper watering is critical for the health of Thuja Green Giant shrubs. Monitor your plants carefully to keep them thriving.

1. Yellowing Leaves

   Yellow or pale leaves can indicate overwatering. Too much water drowns the roots and blocks oxygen.

2. Wilting

   Both over-watered and under-watered plants may wilt. Check the soil moisture to determine the cause.

3. Brown Leaf Tips

   Brown tips often mean underwatering. Dry soil stresses the plant, leading to dry leaves.

4. Moldy Soil Surface

   Mold growing on top of the soil is a sign of excess moisture and poor drainage.

5. Root Rot Signs

   Foul smell from the soil or mushy roots indicates root rot, common with overwatering.

6. Slow Growth

   Stunted growth might be due to underwatering, as roots can’t access enough nutrients without water.

7. Drooping Branches

   Branches droop when they get too much water because heavy, waterlogged soil can’t support healthy roots.
