Hydrangea Repotting: A Step-by-Step Guide. The following steps will help you effectively repot hydrangeas:
Preparing the soil in which we will plant the plant is the first thing to do. Use a mixture that is particularly rich in organic matter and has soil for acidophilic plants or soil that has been previously acidified. We advise using this soil while repotting hydrangeas (Order it here).
2. Collect the potted hydrangea, seedlings, or cuttings that you intend to repot. If you must remove the plants from the ground, take great care to avoid damaging their roots. If they are crammed together due to the age of the plants, use your hands to gently loosen them up as much as you can.
Make sure the soil is in good shape as well as the hydrangeas themselves before repotting them. If you notice or suspect rot, you must cut the affected areas and stop watering the plant for a few days. If you notice or suspect a fungus or other parasites, you must treat the area as necessary (Order it here).
3. Set the plant in the fresh dirt, making sure to completely encircle the stem’s base and the roots. It is crucial to remember that the new pot needs to be bigger than the old one and that it should be placed in the shadow for the first few days so that the plant can adjust to the sun without being stressed.
4- Keep the air humid during the first few days by frequent watering that doesn’t result in waterlogging and making sure you’re wetting the soil rather than the plant.
What time of year is ideal for repotting hydrangeas?
Repotting your hydrangea in the spring or summer, when the plant’s roots are actively expanding, will yield the finest results. Select a pot with drainage holes that are only a single or two inches larger in diameter than the existing pot. Clip out any dark or rotten roots before gently removing the plant and loosening the soil around the root ball. Before transplanting, make an effort to dig out as much soil as you can to check for bugs dwelling among the roots. Plant the hydrangea in the new container at the same height as it was in the previous one.
What kind of soil is ideal for hydrangea potting?
We automatically think of huge plants when we think of hydrangeas because of their enormous foliage and larger-than-life blooms. However, hydrangeas actually come in not one, not two, but three sizes!
Regardless of the size of your area, locate the ideal hydrangea. Even hydrangeas can be grown in a container.
1. Small Is Everything. Choose a hydrangea that will grow well in your restricted space. Dwarf variations are small yet mighty little beauty. To select the ideal dwarf hydrangea for you, browse our Hydrangea Variety Guide. Then, locate a location that has the appropriate level of illumination.
2. Bold, large, and riddled with holes To create a statement, choose a pot or repurpose a container. Ensure that it has drainage holes alone.
3. Gold Soil Solid. Choose a high-quality, organic potting soil for hydrangeas because they require well-draining soil to thrive. If it possesses Myco-toneTM mycorrhizae, which use 30% less water than conventional soils, it gets bonus points.
5. Decide on the necessities. Water hydrangeas in containers when the top inch of soil becomes dry or when the plant starts to wilt. Feed your hydrangeas once a year in June or July with an organic fertilizer for the finest hydrangea care. Feed your hydrangeas with Holly-tone if you want them to be blue.
Big blossoms in a small space! Just picture how beautiful your hydrangeas will appear at your Memorial Day party shimmering in the sun or glimmering in the moonlight at your summer garden gatherings!
Are hydrangeas better in the ground or in pots?
Maintaining hydrangeas in pots is easy, and they provide a beautiful addition to a deck or patio’s color and structure. Additionally, they go well with modern gardens as well as country gardens.
You already know that hydrangeas want moist, organically rich soil that doesn’t dry out over the summer if you’ve read up on how to cultivate them. They thrive best when planted directly into the ground because containers have a tendency to dry out much more quickly.
But that doesn’t mean you can’t use these blooms to make a lovely container arrangement. Simply make sure to take good care of them, choose your compost wisely, and plant them where they will thrive. Additionally, some kinds are better suited to these circumstances. Everything you need to know about taking care of hydrangeas in pots is included in this guide.
Can I replace a hydrangea in a pot?
Our greenhouse is loaded with lovely potted Hydrangea plants before Easter and Mother’s Day. These are great gifts, but many people worry if it’s feasible to store them and plant them in the landscape later because they are produced in a greenhouse and are in flower months before their normal blooming season when grown outdoors. Here are a few success suggestions:
- On Cape Cod, the majority of hydrangeas offered as gift plants are hardy. They will develop flower buds in August, just as regular Hydrangea macrophylla, and those buds will bloom the following summer. If wintertime temperatures fall below 10 degrees, these buds are susceptible to damage from the cold. As a result, these will have less blossoming in the summer following a cold winter, just like all of our pink and blue hydrangeas.
- Hydrangea plants in pots dry out rapidly. The hardest part of keeping them indoors in April and May is doing this. The best course of action is to move your greenhouse Hydrangea as soon as possible into a little bigger container. Make sure the pot you use has a drainage hole and is about an inch larger on all sides. Fill in the gaps with fresh potting soil, but don’t pack it in too tightly. Squeezing the air out of the openings will prevent the roots from growing and will also prevent the water from flowing.
- After repotting, keep your hydrangea in a sunny area, but avoid placing it at the window with the most sunlight. The ideal window is one that faces east. Additionally, plants will flourish if they are placed close to but not directly in a southern or western window.
- If the soil on your hydrangea starts to feel dry, water it right away to prevent drooping. Keeping the pot submerged in water for more than an hour could result in the roots rotting.
- Put your hydrangea outside in part shade at the end of May, then bring it inside at night for a week. Place your Hydrangea after that week in a location that will provide morning sun and afternoon shade. Don’t let its current tiny size deceive you; most Hydrangea shrubs grow at least four feet high and wide.
In our naturally acidic soils, red-toned Hydrangea blossoms will turn a dark purple or blue. The blossoms will continue to be red or pink if the soil is still alkaline.
Even though these hydrangeas were produced in a greenhouse, they should develop and bloom the following year provided the correct conditions during the winter.
Long-term, hydrangeas are not the best indoor plants. However, if you reside in a region where winter lows often drop below 5 degrees, you can plant these in pots and overwinter them in a garage or another warm location where temps won’t fall much below 30 degrees. Don’t worry, they will start to leaf out in the garage in March. Just remember to keep the soil moist but not soggy, and move the plants outside once the risk of frost has passed. Ideally, they should bloom in late June or early July. When you set the pot outside for the summer, fertilize with an equal mixture of Osmocote and Holly-tone or Flower-tone (one tablespoon each per pot).
Do hydrangeas thrive in containers?
Selecting the appropriate-sized planter for your hydrangea is the first step in planting. Because their roots are vigorous and quickly fill smaller containers, hydrangeas do not grow well in smaller containers. Additionally, smaller containers dry out far too quickly for hydrangeas. Generally speaking, we advise purchasing a medium to big planter that is at least 2 feet wide.
Make sure there are drainage holes at the bottom of the planter once you’ve chosen it. It is necessary for hydrangeas to be grown in pots because they will decay if the soil lacks adequate drainage. To aid in drainage, we also like to add a layer of rocks at the bottom. The most important stage for healthy plants is proper drainage.
You must then purchase soil made especially for planters. In containers, topsoil can occasionally fail to drain properly. Compost can be applied to the soil to provide additional nutrients.
Plant the hydrangea at the same depth in the soil as it was in the pot it was previously growing in when putting it in the pot. To water the planter without the water washing out the top, leave at least 2 inches between the top of the soil and the top of the planter. To assist the plant stay firmly in the pot, gently press down on the dirt around it to remove any air pockets.
When do hydrangeas bloom?
The type, cultivar, planting zone, and hydrangea blooming season all affect when they bloom. The majority of hydrangeas with new growth form buds in the early summer in preparation for blooming the next spring, summer, and early fall. Hydrangeas may stop flowering in the heat of the summer in hot locations, but they will blossom again in the fall.
How do you cut back hydrangeas?
Hydrangea plants don’t require pruning if they are allowed plenty of room to develop in the garden. Only the periodic clearance of dead wood is necessary.
Do you need to deadhead hydrangeas?
Your hydrangeas will continue to bloom into the fall if you deadhead them. Hydrangeas make wonderful cut flowers, so there’s no need to wait until the flower wilts. Leave the early fall blossoms alone so they can fade naturally. In the days leading up to your freeze date, you don’t want to promote new growth.
How do you control hydrangea color?
The distinction of hydrangeas is that you can modify their color. But keep in mind that not all hydrangea varieties can change their color. H. macrophylla, a species of bigleaf hydrangea, responds to changes in soil pH. Hydrangeas can absorb aluminum thanks to a low soil pH, which gives the blossoms a lovely blue hue. Reduce the pH of your soil by mixing in sulfur or peat moss to enhance the number of blue hydrangea flowers. Throughout the growth season, you can keep amending your soil with extra aluminum sulfate. When you add ground limestone to boost the pH, pink and red blooms shine.
You may precisely modify your hydrangea color using a soil pH test. To avoid the plant from being harmed, keep the pH level below 7.5. In the fall, all hydrangeas will naturally fade regardless of the modifications you’ve made. Don’t worry, the plant will display vibrant, new blossoms once more in the spring.
Can hydrangeas grow in shade?
Although they won’t blossom in complete shade, hydrangeas prefer dappled or infrequent shade. How much sun do hydrangeas need is more important to consider than whether they love the sun or the shade. Your hydrangeas require more sunlight the further north in your garden you are. A general guideline is six hours of sunlight each day. However, southern hydrangeas can thrive with just three hours of sunlight per day.
Can hydrangeas grow in full sun?
While hydrangeas prefer morning sun, they struggle in the hot, afternoon sun. For these gorgeous creatures, partial shade in the later hours of the day is optimal.
Can you grow hydrangeas in pots?
Even if you don’t have enough room in your garden to cultivate hydrangeas, you can still enjoy these lovely blossoms by learning how to grow hydrangea in a pot. As long as you follow the fundamentals of caring for hydrangeas, the procedure is rather straightforward. Select a pot with at least an 18-inch diameter to accommodate the mature size of the particular hydrangea you are growing. In order to maintain the constant moisture level that hydrangeas demand, look for non-porous containers. Excess water will be able to adequately drain thanks to drainage holes. Consider growing dwarf hydrangeas like Buttons ‘n Bows, Mini Penny, and Little Lime.
How do you keep hydrangeas from wilting?
Morning irrigation on a regular basis can assist stop withering. Some hydrangea cultivars simply can’t stand the heat. No matter how much water you give them, they will begin to wilt in the afternoon heat. Mulch applied in layers can help soil retain moisture and stay cool. You shouldn’t be concerned if your hydrangeas bloom again once the day cools. A little midday wilting is preferable to overwatering and drowning your hydrangeas.
Do hydrangeas respond well to Miracle Grow?
There is no need to buy expensive plant food. This cost-effective alternative has a 15-30-15 N-P-K composition that encourages more flowers per shrub and colorful flower heads. Including hydrangeas, this all-purpose blossom enhancer can be applied to a large selection of permanent and annual blooming plants.
It offers a variety of minerals, such as iron, copper, and boron, to complement typical dietary deficits. For the biggest, brightest blooms and healthiest plants, the water-soluble formulation should be applied every 7 to 10 days throughout the growing season.
- Water-soluble fertilizer, type
- Ratio of NPK: 15-30-15
- Approximately 1.5 pounds

Are hydrangeas compatible with Miracle Grow potting soil?
Choose a location in the South where there is morning sun and afternoon shade. Hydrangeas can tolerate full-day sun in the north. Add Miracle-Gro Garden Soil for Trees and Shrubs (in-ground) or Miracle-Gro Moisture Control Potting Mix to the soil to improve soil nutrition and drainage (containers).
Can topsoil be used to plant hydrangeas?
- When roots are spread out, they grow more quickly. So that the root system has lots of room to easily expand, make the hole deep and wide enough. So that you may place the dirt at the bottom of the hole, where it will be most beneficial, keep it in a separate pile.
- Mix dehydrated cow dung, garden compost, or peat moss (up to a 1/3 concentration) into the topsoil pile to help the soil become looser. Make sure the peat moss you purchase is either granular peat or baled sphagnum. You may also mix in 2 or more inches of organic material or our Coco-Fiber Potting Medium evenly with the current soil.
You can get the perfect organic ingredients from your lawn, such grass clippings and crushed leaves. The grass and leaves not only decompose to replenish the soil’s nutrients, but also to assist loosen the soil. These can be collected in the fall in preparation for spring planting.
Common soil amendments:
- compost
- sand
- manure
- lime
- bog moss
Most soil types will benefit from the addition of organic elements like our Coco-Fiber Potting Medium and compost. Sand-like soil particles are bound together by organic compounds, improving moisture and nutrient retention. Additionally, they disintegrate clay and silt particles to allow water to permeate and allow roots to grow.
