Clivia love fertiliser. Fertilising your plant will result in darker green leaves, more growth, a better root system and better flowers. I have often seen plants in need of a good fertilising and the leaves have taken on a more lime green colour. Nothing looks better than a healthy plant with dark green leaves and new leaves developing.
I use a slow release fertiliser that lasts for 12 months on my plants. A small amount is mixed throughout the potting medium and a handful is sprinkled around the top of the pot. I also give my plants a liquid fertiliser once per month. These are plants in pots. Plants in the garden would also benefit from a slow release fertiliser and the occasional watering can of liquid fertiliser.
The following fertilisers are the most popular ones used at present. There are many more good fertilisers not listed here but I have not had experience with the others.
Seasol
Seasol is not a fertiliser. It is more of a tonic. I find it great to give to a stressed plant or when I have just repotted a plant. I use it on plants that seem to have a problem or have dried out too much. It is reported to be good for root growth. I use it diluted in water and watering it in with a watering can.
Aquasol (No longer available)
I find Aquasol a great liquid fertiliser. I give it to my mature plants and a diluted version to my seedlings. I sometimes use it as a foliar spray and sometimes in a watering can.
Charlie Carp
Charlie Carp is a very smelly liquid fertiliser. I have heard some experts say that it is not as good as others such as Aquasol due to the carp living in fresh water and not sea water. I have used Charlie Carp extensively and find it great, however be aware you will need a shower afterwards. I also like the thought that we are helping to get rid of the carp in our rivers.
Thrive
Thrive is also a great fertiliser. I find that it is great for the growth of the leaves and not so much for inducing flowering. I use it at times on my seedlings.
Osmocote
I love Osmocote and buy it in a large quantity but it is also available at Bunnings. It is a great slow release fertiliser and has everything the plant needs.
Powerfeed
This product is made by the same company as Seasol. I use this on my young seedlings as I find it is not too strong and encourages growth. I use this as a foliar spray.
Seamungus
This product I also use on seedlings. It comes in a pellet form or a crumble form. I find this not too strong and very good for the young plants.
