Growing hydrangeas in pots are relatively simple. In order to grow your hydrangeas in a pot you need to make sure that the soil contained in the pot or container is well-drained, the location in which you place the pot receives the proper amount of sunlight, and the soil remains properly moist as they need regular water and will suffer quickly if they don’t get enough water.
Growing hydrangeas in pots is a wonderful option for anyone who has a small garden or some limited space and wants to add a beautiful look. This is also a perfect option for people who have locations that get adequate sunlight in the morning but not in the evening such as porches, decks, balconies, entryways, or patios. More importantly, growing in pots doesn’t just mean leaving a pot on top your balcony. If you have difficult soil, soil that is simply not well-suited to hydrangeas, you can save money by planting the hydrangea in a pot with the right type of soil
Planting hydrangeas in pots
The first step is to pick out the appropriately sized container for your hydrangeas. Hydrangeas won’t do well in smaller containers simply because the roots grow very quickly and very aggressively which means they will outgrow the small container. Smaller containers also dry out far too quickly. It is recommended that you get medium or large size planters for your hydrangea and once you have picked out the planter make sure you have adequate drainage holes at the bottom which is something often overlooked.
In many cases, the drainage holes that are pre-drilled into a pot or insufficient and you might need to take a drill and create a few new holes just to add better drainage. The roots will rot if there’s insufficient drainage so don’t skip this step. It’s also beneficial to put a flat layer of stone or broken pots at the bottom to encourage better drainage. This really is one of the most critical steps to maintaining healthy hydrangeas. After this, you need to select soil or compost that is designed specifically for planters and also your hydrangea type if your trying to produce blue or pink blooms by altering the Ph level.
When you are ready, you want to plant your hydrangea at the same depth as it was grown in whatever container. This means that if you purchase a hydrangea from a nursery and it is in an existing container, the level at which it is buried needs to be maintained when you place it into the new pot or container at home. If you bury it too deeply it will not thrive. You need to leave at least 20mm from the top of the soil to the top of your planter so that you can water it after you plant it without any of that water washing off. Once you place the hydrangea in the soil, gently push down around the plant to get rid of any air pockets and keep the soil firm.

Best compost for hydrangeas in pots
The best compost for hydrangeas in pots is not necessarily topsoil because it won’t drain well enough. You want to add potting soil and integrate compost into it to add more nutrients
You can go to any garden centre or nursery and purchase potting soil as well as compost and simply mix it by hand in the container before planting the hydrangea.
You could simply go for a compost that is specially made for shrubs but if you want to grow blue mop head hydrangea you need to make sure you use ericaceous compost or it will probably produce pink flowers.
Don’t forget to use ericaceous compost if your hydrangea has blue flowers
After you have planted the hydrangea and chosen the right compost, the maintenance required is fairly simple. Just make sure that the location of the pot meets with growing requirements for the variety of hydrangea you have. Most hydrangeas prefer morning sunlight and afternoon shade. If you’re planting a larger hydrangea it’s best to verify the location and then move the pot to that area and plant the hydrangea directly rather than trying to plant a hydrangea in a pot elsewhere and move it after the fact.
keeps the soil moist
Be sure to check on the soil levels and keep the soil moist. Usually, hydrangeas in pots require watering at least twice a week but given the conditions of the weather at any given time that could change. If the leaves start to droop, it’s indicative of a bit of drought. Simply water your plants. If you’re going to fertilise it, do it at the end of winter or the beginning of Spring and use a slow-release fertilizer. Never feed after August as this can promote new growth that can be damaged by frost in winter.
Caring for hydrangeas in pots in Winter
When it comes to winter time, you have two options:
The first is to bring your pots inside where they will be protected from the winter weather. It is advisable that you do this if at all possible and keeping it on a greenhouse over winter should offer enough protection.
The second if they are simply too large to move inside or you don’t have space is to create a protective barrier around the hydrangeas. The best way to do this is to utilize stakes or sticks as well as chicken wire. Create a fence around the hydrangea after you’ve cut it down, pack the area down with material like pine needles which still allow for proper air flow. When you do this make sure that you don’t break any of the branches. After that cover the entire structure with a breathable material like a burlap sack. Do not use something like plastic because this won’t allow air flow.
You can also now buy fleece jackets you place other the plants now too which could be an easier alternative and don’t forget to wrap the pot in fleece or lagging to protect the roots.
You can prune as you would if they were grown in the ground, most hydrangeas in the pots can just be deadheaded to encourage new blooms. Read more on pruning hydrangeas here
