How to Care for Hydrangeas
Hydrangeas are one of the most famous flowering shrubs in gardens. They are loved for their beautiful, showy flowers and can make any yard a happy, colorful place. These plants can be used in almost any yard because they come in many colors, from dark blue to soft pink to bright white. Whether they are grown in a yard or a pot, hydrangeas add color to any outdoor space.
A healthy hydrangea needs to be cared for in a number of important ways, including choosing the right variety and planting site and learning how to water, prune, and get rid of pests. This article will teach you everything you need to know to keep your hydrangea plants healthy and their flowers looking beautiful for a long time.
Choosing the Right Hydrangea Variety
There are different kinds of hydrangeas, and each one needs different care. If you want to succeed, pick the type that will do best in your environment and garden. These are the most popular types of hydrangeas:
Bigleaf Hydrangea (Hydrangea macrophylla): The most famous thing about bigleaf hydrangeas is that their color can change based on the pH of the soil. They are known for their big clusters of ball-shaped flowers. If the earth is too acidic, they can turn blue, and elsewhere they can turn pink. This variety does best in partial shade and is ideal for temperate climates.
Panicle Hydrangea (Hydrangea paniculata): These plants have cone-shaped flowers and can handle sun than others. They can also handle cold weather better. In colder places, these are often the best choice for farmers.
Smooth Hydrangea (Hydrangea arborescens): These are tough and hardy hydrangea that are known for their big clumps of white flowers. They do well in a range of situations, which makes them great for beginners.
Oakleaf Hydrangea (Hydrangea quercifolia): The leaves of this type are shaped like oak leaves and turn red and orange in the fall. Oakleaf hydrangeas do best in shady spots and look great in woodland gardens.
Ideal Planting Conditions
For good growth, it’s important to plant hydrangeas the right way. This is what you need to know to plant hydrangeas:
Soil
Hydrangeas like sandy, well-drained soil that has a lot of organic matter in it. That’s because root rot can happen in heavy, clay soils that hold too much water. Before planting, add compost or well-rotted manure to the soil to make it better.
Light
Most hydrangeas like some shade, especially in hot places. Too much direct sunshine can make the leaves wilt, so it’s best to have morning sun and afternoon shade. Some types, like panicle hydrangeas, can handle full sun better than others.
Plenty of Space
Hydrangeas need room to grow. They can grow anywhere from 3 to 10 feet apart, depending on the type. Make sure there is enough room between each plant so that air can flow freely.
Watering at Planting
Give your hydrangeas a deep, thorough watering right after planting to help the roots take hold. During the first few weeks, keep the soil consistently moist but not waterlogged.
Watering Hydrangeas
Hydrangeas need a lot of water, especially when they are just starting to grow or when they have been moved. To make sure they get enough water, do the following:
Frequency
Depending on the weather and soil conditions, hydrangeas must be deeply watered about once or twice a week. During dry times, you may need to water them more often. Remember that hydrangeas have weak roots, so they need to be kept moist all the time, especially when it’s hot outside.
Method
Water the plant fully at the base so that the water can get to the roots. Do not water plants from above, as wet leaves can cause fungal diseases like powdery mildew.
Mulching
Putting mulch around the base of the hydrangea can keep the soil wet and even out the temperature. Organic mulch are wood chips, pine straw, or fertilizer that is made from living things. Spread the mulch out in a layer of two to three inches, but don’t let it touch the roots directly to keep them from rotting.
Fertilizing Hydrangeas
Regular fertilizing will help plants grow well and produce bright flowers. But too much fertilizer can make the plant have fewer flowers and more leaves, so it’s important to find the right mix.
When to Fertilize
Hydrangeas must be fed twice a year, once in the middle of summer and again in the spring when new growth starts. Don’t fertilize in the fall because it can cause new growth that could be hurt by frost in the winter.
What to Use
For general care, use a balanced, slow-release fertilizer like 10-10-10. You can change the color of the flowers on bigleaf hydrangeas by using a fertilizer made for plants that like acidic soil.
Special Considerations for Flower Color
As we already said, the pH of the soil affects the color of bigleaf hydrangea flowers. If you want blue flowers, you should add aluminum sulfate to the soil to make it more acidic. The soil can be made more alkaline by adding lime. This will help the flowers grow pink. This process can take a while, so plan ahead if you want to change the color of your hydrangea as it grows.
Pruning Hydrangeas
Hydrangeas need to be pruned to keep their shape and size under control and to promote healthy growth. However, different types need different ways to be pruned:
Bigleaf hydrangeas: Their flower buds were made the year before, since they bloom on old wood. Cut back the plant right after it blooms, removing any dead wood. Don’t prune too much because it can reduce the blooming of flowers in the next season.
Panicle and Smooth Hydrangeas: These varieties bloom on new wood, which means that their buds form on new growth that came up this year. Cut them back in late winter or early spring before they start to grow new leaves. To get strong, healthy growth for the new season, you can cut them back by about a third.
Oakleaf Hydrangeas: These grow on old wood, just like bigleaf hydrangeas. After they flower, prune them to remove dead wood and shape the plant. But don’t cut too much, or the plant might not flower as much the next year.
Regular pruning helps the plant keep its shape and health, and it also makes the flowers grow more strongly.
Managing Pests and Diseases
In general, hydrangeas are hardy plants, but they can get bugs and diseases. Here are some well-known problems and how to fix them:
Aphids
These tiny bugs can make leaves curl or warp and stop flowers from growing. You can get rid of them by spraying the plant with neem oil or insecticidal soap.
Slugs and snails
These pests can eat holes in the leaves, especially when the soil is wet. To keep slugs away, put down slug traps or cover the plant’s base with diatomaceous earth.
Powdery Mildew
This fungus disease makes the leaves look white and powdery, which can make the plant yellow or wilt. Powdery mildew can be avoided by ensuring enough airflow around the plants and not watering them from above. A fungicide should be used to get rid of mold if it appears.
Leaf Spot
Brown or black spots appear on leaves because of the leaf spot. This can cause the leaves to fall off. To stop this from happening, remove and destroy any leaves that are damaged, and don’t wet the leaves when you water.
You can keep these problems under control and make sure your hydrangea stays healthy and bright by checking on it often and taking action early on.
Winter Care for Hydrangeas
Most hydrangeas can handle cold weather, but types that bloom on old wood may need extra care in colder areas. In the winter, take care of them like this:
Applying mulch: Wrap a thick layer of mulch around the plant’s base to keep the roots from freezing.
Protecting Buds: Covering the plant with burlap or a frost blanket will protect the buds from frost damage, which can reduce the plant bloom next year. This is especially important for bigleaf and oakleaf hydrangeas.
Watering: Hydrangeas still need to be watered in the winter, especially if they were just planted. Make sure the soil stays damp, but don’t water it too much.
Hydrangeas in Containers
You can also grow hydrangeas easily in containers, which is great for gardeners who don’t have a lot of room. Some tips on how to take care of containers:
Choosing the Right Container: To keep the soil from getting too wet, choose a big pot with ventilation holes. The pot for a hydrangea needs to be at least 18 inches wide and deep because the roots are pretty big.
Soil: Use a good potting mix that drains well, and think about adding organic matter like compost.
Watering and Fertilizing: Hydrangeas grown in pots may need more watering than those put in the ground. Fertilize your plants often, but be careful about over-fertilizing, which can cause root burns.
Winter Protection: If you live in a colder area, bring planter hydrangeas inside or move them to a protected area to keep them safe from frost.
