If you are growing camellias, you want to make sure they get the right amount of fertiliser, and at the right time of year. But when exactly is that? And how much do you give them? This article will help give you a better understanding of when and what you should be feeding all of your Camellias so that they can remain top quality producers.

The quick answer is that camellias should be feed in spring after flowering with an acidic or ericaceous feed which is sold for feeding camellias, rhododendrons and azaleas. Then feed every few weeks with an ericaceous liquid feed if grown in containers until around September. Below we have some recommended feeds you can also buy.

The right amount of food at the right intervals will make the difference between a successful, thriving shrub and one that just barely survived.

Feed camellias in spring after flowering

It is recommended that you fertilise your Camellias in the springtime, right after the flowers have faded. However, prior to fertilizing, make sure you pick off any faded flowers from the shrub with a process called deadheading. Concurrently remove any flowers that have fallen around the shrub on the ground. You want to remove all of this so that the Camellia doesn’t start forming seeds and so that the bush looks beautiful.

Camellias just like any plant have finite energy resources and it will be dispersed in order of what’s most important. If you fail to deadhead before you fertilize, you will simply be giving your Camellia extra energy which it will allocate toward seed formation, draining energy from the rest of the plant and stunting growth immediately. By removing the flowers after they have stated you can also help control one of the most common problems gardeners experience with Camellias, blight.

Feed over summer to promote new growth until around September

You can also fertilize in the middle of summer. Adding fertilizer like this will help give a second round of new growth more sensitive to colder weather. You should be fertilizing in the middle of summer at least two months prior to the first frost so that all of the new growth has an opportunity to harden in the cooler temperatures before the onset of winter, in most parts of the Uk this is usually around September. You’ll know if you waited too long because the new twigs and branches will suffer frost damage as they want have had time to mature.

When it comes time to feed your Camellias, you want to pull back the mulch around the base of your plant before fertilizing. This will prevent the fertilizer from running off elsewhere never making it to your plant. Thankfully these shrubs don’t need a lot of food. In fact, having too much nitrogen can burn their leaves. If you start to see all the leaves fall off right after you added fertilizer, that’s probably what happened so its better to under fertilise than over-fertilizing. It’s best to spread sulphate of iron or slow-release fertilizer for acid-loving plants all around where the roots are. You can actually scratch the surface of the soil with a garden rake about 3 or 4 cm deep, then add the fertilizer on top and cover the fertilizer with mulch or ericaceous compost when all is said and done. Water it deeply directly after you have added this fertilizer so that all of the nutrients are able to break down and get into the soil.

If you have a well-established Camellia, one that is grown directly in the ground in your garden and not in a container, you can use a special fertilizer designed for camellias. Camellias prefer soil pH levels between 4.5 and 6.5 so the Camellia specific fertilizers will acidify your soil which is why you want to use it on established plants that are grown in the ground. Different brands will have varying percentages of nutrients so it’s important that no matter what type of food you buy, you read the label and following instructions printed on the label.

If, after feeding your Camellia you notice that the leaves turn yellow and drop immediately, it could be symptomatic of too little fertilizer or a pH level that’s too high in the soil itself. You should use an at-home ph test kit to verify the pH level of your soil before adding more fertilizer. You should rule that out before you increase speeding because of too much fertilizer can, as mentioned, harm the plant as well.

Overall, by paying attention to when and how you feed your Camellias, you can make sure that the shrubs produce stunning flowers, stay healthy and vigorous throughout the season.
