Keep the Hydrangeas alive.

There are a variety of sizes and colors of hydrangeas.If you want to keep your plants looking nice, be sure to water and fertilize them.If you want to cut the stems, try dipping the tips in alum spice powder, changing the vase water frequently, and dunking the blooms in water. Step 1: The stems need to be cut at an angle. Give your stems a deep diagonal cut.Cutting the stems under warm running water will help prevent air bubbles from forming on the stem. Step 2: Cut the stems and then dip them in alum spice powder. A small amount of alum powder can be placed on a plate.Once the stems are cut, dip them in the alum powder.Put the stem in a vase with water and arrange the flowers.For a longer period of time, this will help the blooms thrive.You can find alum in the spices section of the grocery store. Step 3: Immediately after cutting, place the cut stems in water. You need to get your hydrangea in water as soon as possible after cutting the stems.3 in to 5 in of room temperature water is enough to fill a clean vase.If you crush the stem ends, you can prevent it from hydrating. Step 4: The petals can be misted with water. The petals absorb more water than the roots and stems.If you want to keep the flowers hydrated, you need to mist them with water each day.It's a good idea to use a spray bottle with a gentle mist stream. Step 5: The water in the vase needs to be replaced every day. Fresh water will help keep your blooms hydrated.Remove the cut hydrangeas from the vase.The vase should be filled with fresh room-temperature water.Before adding fresh water, rinse out the vase. Step 6: If your flowers are exposed to high temperatures, add ice to the vase. The vase should be filled with 2 parts ice and 1 part water.If the plants are overheated, this will help.After one day, you should see improvements.If you want to revive your hydrangeas, you can continue the ice/water treatment for several days. Step 7: The flower heads can be dunked in warm water. Submerging your hydrangea blooms in a bowl of warm water for up to 30 minutes will give them a bit of life support.The water can make the hydrangea heavy, so be careful when lifting them back up. Step 8: You can protect your hydrangeas from the wind by planting them in the sun. If you want to grow hydrangeas, place them in a spot with either full or partial sun exposure.It's a good idea to plant your hydrangea away from the wind.It's a good idea to protect your plant from the wind and keep it hydrated. Step 9: Plants in moderate climates. The U.S. Department of Agriculture has plant hardiness zones.It is ideal to have a daytime temperature of 70 F and a nighttime one of 60.The blooms might die if it is hotter than this.The foliage may be affected by frost.The buds that will bloom the following year are made in the fall.During this time, the buds need to be set in 6 weeks. Step 10: You can plant your hydrangeas with standard potting soil or compost. If you plant your hydrangeas in the ground instead of in a pot, you need to add some potting soil or compost to the hole to help the plant handle the transition.The color of the flowers is determined by the soil's pH level.Blue hydrangea blooms can be produced by a high number of aluminum ion in the soil.Pink hydrangea blooms can be produced by a pH level of 6.0 or higher.White hydrangea blooms are unaffected by the soil's pH level. Step 11: The soil needs to be watered every day to keep it moist. During the first couple of years, hydrangeas need to be hydrated.The leaves and petals will start to fall if the soil is too dry.If you want to see how your plants do, try watering them every day with just enough water to keep the soil moist.Water your plant at least 3 times a week.If you live in a dry climate, you may want to water less.Try to water more if the leaves start to fall.If the plant starts to look wet, consider watering less frequently. Step 12: Your plant needs to be trimmed. Cutting off some of the plant to improve health and growth is a very common practice.Remove stems and shoots that seem to be fading.Always cut above the stem.New growth will be allowed if old growth is removed. Step 13: If you want to protect the plant from frost, cover it with leaves or mulch. If you want your hydrangeas to survive the cold season, it is a good idea to cover them from the fall to the spring.They will be protected from the cold weather by this.The plant should be covered with 18 in (46 cm) of bark mulch, pine needles, leaves, or straw.If you want to cover the entire plant, you can place a loose cage of chicken wire over it.To keep the plant insulated from the cold, fill the inside of the cage with leaves and mulch.If you want to do this project, don't use maple leaves. Step 14: To prevent gray mold, trim the affected area and spray with a fungicide. There is a disease called gray mold that affects plants.If you see a fuzzy gray spot on your plant, it's time to trim it off.Remove the affected area and discard it.If you want to protect your plant from further infections, spray it with an organic fungicide.It's a good idea to make sure your shears are clean before you cut them.Liquid spray or wettable powder can be used as a fungicide.Sulfur can damage the plant in hot weather, so be sure to stop using it when the temperature is over 80 F.Water from beneath the branches to prevent the leaves from getting wet.This will help prevent mold.
