The one thing that doubled my Fiddle Leaf Fig growth- The right was to use fertilizer!

Hello again plant lovers! It looks like there are more than a few of you out there who are just as obsessed with growing a healthy Fiddle Leaf Fig tree as I am! I’ve already written a few posts on caring for Fiddle Leaf Figs which have been some of my most popular posts.

Whenever I discover something new about my FLF, I like to share it with you and keep you up to date with everything I’ve learnt about looking after these house plants.

I have touched on the one thing that doubled my Fiddle Leaf Fig growth in a previous post. But I realised I may not have put enough emphasis on it, and it really deserves a post all of its own!

This one thing may not be ground-breaking. But what may be new to you is how and when to do it, and which type is best. Yep, you may have already guessed, its to fertilize your Fiddle Leaf Fig!

Firstly let me tell you, from when I first started fertilizing my Fiddle Leaf Fig, the growth has been AMAZING! The new leaves literally more than doubled in size, and my FLF tree grew twice its height in just one growth season. It grew more than it ever had before! This may seem like the greatest growth hack, but in fact, fertilizers for plants are kind of like multivitamins to humans. They make sure the plant is topped up on all the nutrients it needs for the best possible growth and health. And who wouldn’t want to give their FLF the best conditions for it to thrive!

So let’s talk about the type of fertilizer. All fertilizers are specifically made for different types of plants and their needs. For Fiddle Leaf Figs, try to look for a fertilizer that has an NPK ratio (Nitrogen – Phosphorous – Potassium) as close to 9:3:6 as possible. This is the ratio that is best for a FLF’s needs. Alternatively, check out this Foliage Pro fertilizer, which already has the perfect ratio required for your Fiddle Leaf Fig’s needs! Its also designed for lush and leafy growth. There are a few different bottle sizes available, depending on how much you’ll want.

How extreme is the size difference on my Fiddle Leaf Fig leaves- before I fertilized, and once I started using a proper formulated FLF fertilizer!

How & When to Fertilize your Fiddle Leaf Fig

Its best to fertilize your FLF in the growth season, aka Spring and Summer. Typically I water my FLF weekly. Then once a month (or every 4 weeks) I’ll take it outside to fertilize as I water it. I give the leaves a spray-down with water to get dust off, and then give it a watering with the liquid fertilizer mix.

Make the mix up according to the instructions. Then water the plant until the excess pours out the bottom. For mine, this is generally about 3-5 litres worth – make sure it’s saturated! I then leave it outside for a couple hours until it has stopped dripping before I bring it back inside. I don’t fertilize mine during winter, or at least do it a lot less than usual. During winter, your FLF won’t be growing very much and you don’t want it to stay wet too long either.

So there you have it! FLF’s may be renowned for being slow-growing. But if you provide the best conditions for them, including the right fertilizer, you can have your FLF growing in lush leaps and bounds.

Fertilizing my Fiddle Leaf Fig is now something I’ll never go without! I can’t wait to see the amazing growth it gets in just one more season. Would you like more tips and info on Fiddle Leaf Figs? Check out my other popular posts here.

    1. Hi Vitalii, I’m sorry this post couldn’t be more helpful for you! I’m speaking from my personal experience, and understanding fertilizers & using the right one was the change that gave my FLF great growth. I have a few other posts on FLFs if you’re looking for other information. Let me know if you have any specific questions and I’ll do my best to answer!

  1. Hi Emily,

    I unfortunately and very sadly killed my first FLF tree and I’m unsure why it died as it grew leaves very quickly then dropped them all. Anyway, I now have a new shrub-like Fig. It was kind of sickly looking when I got it but now it is very healthy. It gets watered once a week and the new leaves are seem to be sprouting g almost daily for the last month. This October, so not the growing season – but my Fig doesn’t know that so when should I fertilize him? Homer is his name. Lol.

    I mentioned he is shrub-like. There many stalks, so this good for his future? I like his “shrubbiness” and would to keep him tris way instead of a single stalk. What are the odds on keeping him this way?

    Cheers
    Angie

    1. Hi Angie, sounds like you’ve got a great FLF for it to be growing so much! You can still fertilize during the cooler months, either by doing a half-strength mix or fertilising half as often as you would in warmer months. That’s totally fine to keep him looking shrubby – the tree-form can require a bit more work to attain but you won’t have to do much to keep one shrubby. You can always prune parts back if they get too tall or out of control. Other than that, Homer should grow fine as a shrub! All the best 🙂

  2. Thanks for the information! I’m trying to find out how to get my FLF to be bushier/fuller. It has no problem growing taller, but I’d like more leaves throughout. Any suggestions?

    1. Hi Amy, if your FLF has sparse growth, it might need more light! Often when there’s not enough light they grow ‘leggy’ in search of light. When it is getting enough light the growth should be bushier. This should help with any future growth, but as for getting more leaves throughout, try tip pruning to activate buds that lay dormant along the stems/branches. When you cut the tip of a FLF, it tricks the plant into thinking it needs to activate growth elsewhere. Hope this helps! 🙂

  3. Hello Emily
    I got a few FLF plant and most of them are doing great but there’s one that I have issues with.When I got it it had small leaf sprouts .Unfortunately they dried off.Now there is no growth of new leafs. What should I do.
    Thank you ,

    1. Hi Memy, if your FLF isn’t growing there could be a bunch of reasons. Take a look at my growing and pruning FLFs post for some info on care to make sure its getting everything it needs. Other than that it may just need time to adjust if its a new plant in your home. Let me know if you have any more specific questions 🙂

  4. Will this also thicken the trunk? I have two FLF bush-types and I have to support them with a stake currently. They are only about 2 feet tall, but it can’t hold the weight of the current leaves. I’m in san antonio and I moved them outside about 2 months ago. They seem to love it – one of them sprouted two new leaves immediately. But they need stronger trunks. Thanks!

    1. Hi Summer, the trunk thickening should happen naturally as your FLF grows. Using a stake is a good way to keep it stable, and the other thing that helps strengthen the trunk is the leaves! When your FLF is getting enough sunlight, the leaves should grow close together which helps support the trunk. If there are spaces between each leaf, it most likely means your FLF needs more light. Moving it to a lighter place should help the leaves grow closer and support the trunk more. Also, some people like to remove the lower leaves on their FLF, but doing this will slow the thickening of the trunk, so let the lower leaves stay. If you are already doing these things, great! Add a little bit of patience and your FLF should get strong enough to support itself 🙂
