What’s the best method to water Bigleaf hydrangea?
Soaker hoses can be the best method to keep the moisture from the leaves and flowers. These methods are great when you want more efficient water delivery at the very base of the plant without needing to get the entire foliage wet.
Lay the hose around the plant, leave it on for about 30 to 45 minutes and wait until the soil is moist but not too wet. Hook your regular hose to this, and cover with mulch. Others may use drip feeders to retain moisture throughout the day.
When planted in pots, you need to water the Bigleaf hydrangea using a watering can. Wait until you see that the water is dripping down the pots at the bottom part. The portable cans can help you reach the soil and let the water penetrate the roots deeply so they can grow better.

What should I do if I water Bigleaf hydrangea too much/too little?
If you overwatered Bigleaf hydrangea, you might want to take a few steps back and prevent further damage. Bigleaf hydrangea is hardy, so they have a higher chance of surviving. Give the plant a chance to dry everything out and stop watering it. The plants don’t tolerate their roots sitting in water for longer, so aerating can help.
Some of the symptoms of an overwatered plant will be premature falling of yellow leaves. You might also see fewer flowers and misshapen buds. In more serious cases, this can result in wilted and brown leaves. Long-term overwatering can result in root rot.
The symptoms of underwatering can be similar. Wilting Bigleaf hydrangea can be a sign of underwatering. Feel the earth by sticking your finger into the soil, and if it’s too dry, then this is a sign of dehydration. Too little watering can also happen, so you might want to add some in the evening. Always check the soil for dryness and follow the regular schedule of watering in the morning.

How often should I water Bigleaf hydrangea?
It’s best to water the Bigleaf hydrangea deeply two to three times a week. And you should water it more often if you live in a hot climate. Its water needs are average, and it needs moist but well-drained soil.
A good rule of thumb is to get a feel of the soil. It might be the right time to water your plant if you notice that it’s about 2-4 inches dry.
Water it 1-2x a week if it’s planted outdoors. Know that it’s getting more moisture outside, watering less with the help of rainwater is ideal.
Read More more
How much water does my Bigleaf hydrangea need?
The amount of water needed can vary. There are a lot of factors to consider, such as the weather in the area, the amount of shade, and the species. The Bigleaf hydrangea you’ve just recently planted will need more water than the established ones. A can of water each week can be ample for Bigleaf hydrangea, especially if they are in the growing season and when they are grown in pots.
When outdoors, you need to measure the amount of rain they are receiving with the help of moisture meters. When the soil is dry, water them thoroughly with a sprinkler. It’s best to water less often but thoroughly with the Bigleaf hydrangea to ensure they are getting the adequate moisture they need.
Read More more
Why is watering my Bigleaf hydrangea important?
Regardless of the types of the plant that you’re growing, it’s important to know its watering needs so that they will grow well. Bigleaf hydrangea needs a lot of water and can quickly wilt without the right moisture.
They require moist soil but make sure that the ground is well-drained. Bigleaf hydrangea doesn’t want wet feet since they tend to get root rot. Overwatering can also lead to slow production of flowers and stunted growth, which can also be a problem seen with underwatering.

How can I ensure that i'm watering my Bigleaf hydrangea adequately?
It's best to water the Bigleaf hydrangea in the early morning to prevent it from wilting. It may be unable to handle the heat and can show signs of wilting in the afternoon. Make sure to apply a thick layer of mulch to keep the soil cool and retain moisture.
Once it feels the coolness of the evening, it will go back to its usual glow. Always water deeply and be consistent with the moisture. However, remember that it’s better to experience a slight wilting in the afternoon than to over-water them.
Read More more
Should I adjust the frequency of watering my Bigleaf hydrangea according to different seasons or climate?
When watering during the summer, it’s important to take the environment into consideration. These plants enjoy the early morning sun but not much of the midday glare since they can dry out too quickly.
It’s best to start planting these species in spring or autumn. Provide ample water, especially when you notice that the soil is dry during the summer. Don’t water the plants during the winter as they will enter a period of dormancy.
Fill the pot up to the rim, let the water soak, and run out of the drainage hole. Always water when the soil feels dry and if you have windy and hot weather. The plant supports a lot of big blooms, and they need ample water to maintain them.
Read More more
Should I change the watering frequency during different growing stages of my Bigleaf hydrangea?
During the growing season, it’s best to water this at a rate of 1 inch when it’s just growing. This should be done 3x per week. When growing in pots, you need to have one with a diameter of at least 18 inches. A non-porous one can help hold consistent levels of moisture.
An established plant does not need watering as much as one in the early phase of growth. They can be watered twice a week but always check the soil to be sure. Just make sure that there will be no waterlogging that occurs.
The plants might experience transplant shock when they are just newly planted. Just water until the depth of the moisture reaches out to 10 inches beneath the surface. Help the roots become more established during the dry, hot weather by checking the soil frequently.
Read More more
What should I be careful with when I water my Bigleaf hydrangea in different seasons, climates, or during different growing periods?
Overall, the Bigleaf hydrangea loves water and should be provided with enough to keep it hydrated.
Be careful not to overwater and never use cold water with them during the winter. They enter a dormancy period and they barely need water to survive.
In the spring, planting should be done where they will be given enough time to grow. Water more when they are young and make sure to give them enough mulch to keep the soil moist.
During the summer, just make sure that the soil is moist. Overwatering can result in a lack of blooms, but a heavy soaking can be done once a day whenever the soil needs this. For 3x a week, ensure water in the early mornings or afternoons.
The ones on the balcony or gardens should be watered generously during the summer months. This is because the water can evaporate quickly.
Read More more
Should I water Bigleaf hydrangea differently when I plant it indoors but not outdoors?
The Bigleaf hydrangea that is grown outdoors doesn’t generally need a lot of water compared to the one grown indoors. This species absorbs the water quickly, so watering can be done twice a week. When you grow Bigleaf hydrangea in partial shades, you generally encourage moisture retention and prevent the drying winds from wilting them. It’s best to keep the water away from the flowers as this can lead to gray mold.
The Bigleaf hydrangeaed indoors can be watered at least 2x a week or more when they are just in the growing phase to help the roots become more established.

Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
Solutions
For less serious cases:
  1. Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.

Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
Solutions
For less serious cases:
  1. Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.
To treat more serious infestations:
  1. Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions.
  2. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Prevention
Prevention
To prevent infestations of leaf beetles, follow these practices.
  1. Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
  2. Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
  3. Attract natural predators. Birds and other insects, such as wasps and ladybugs, are effective natural predators of leaf beetles. Encourage them to visit by including a diverse array of plants to provide habitat and food. Also, avoid applying broad-spectrum herbicides that can harm and kill beneficial insects.
  4. Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.
