Mixing fertilisers - container suggestions.

[Time Waster]

A bit of a basic or noob question, but what do you use for mixing and storing fertiliser used for small batches like houseplants?

I have a very modest cacti collection and this year I'm looking at caring for them a bit better. I've repotted a few into cacti and succulent compost, more free draining. Now I'm looking at fertiliser. I've got a cacti concentrate fertiliser I need to dilute, half capful per litre. So I'll not use the full litre but need to store it for the next feed. What would you suggest for a container I can seal but also measure out the water easily for mixing? I'm thinking of a suitable litre capacity with markings and a lid for sealing it when finished with feeding my plants.

Stupid question as a cheap drinks bottle would do but I'm thinking something that won't get confused with our numerous actual drinking bottles. I don't think a litre watering can would do because it cannot be sealed but a drinks bottle might get confused so doesn't suit neither.

I use a plastic supermarket type milk bottle, store it under the sink and make it obviously not milk.

It won't keep like any liquid fertiliser once it's made up it has a limited shelf life. As the chemicals break down over time it will still be safe to use but it's nutritional value will be a lot less. Even the concentrate has a limited life. The dripper type feeders or stick type that go into the pots are best if you don't need a lot of fertiliser.

Just don't be mixing it with diesel and ground charcoal!

Mix a quarter cupful to half liter of water?
Or mix the full liter, discard the extra?
I wouldn't keep chemicals in food stuff containers, especially inside the house, would be different in a shed or garage - if you don't have kids about.
Like @tom73 said up thread, the mixed stuff doesn't last as long as the concentrate.

I think in the sunny months of May and June I'll probably fertilise out every other week. It should be good enough after 2 weeks from mixing. Certainly better than not using fertiliser. I've got at least one that should flower so I giving a good feed to try for some this year. Last year without much feed just new compost some really took off. One doubled in height! Really grew fast for a supposedly slow growing plant.
