Hello there everyone. I have a quick question, I'm planting some watermelons, peppermint and lavander plants on some plastic pots. I'm using miracle grow moisture control potting mix and I want to know what types of fertilizer I need to use for each plant or if the potting mix already has all nutrients necessary
.thank you very much for your help.

Potting mix should have it already. Check the label.

The potting soil has nutrients in it, probably enough for the whole season. Moisture control potting soil is a mistake though - it stays too wet for too long.

Daisy and Bill made some good points... the general rule for fertilizing potted plants is to apply at half strength, at measured intervals. The times you fertilize would be determined by how often you water. Plants confined to a pot and watered frequently need it more. Also anything that blooms all the time needs it more, ie annual flowers. For veggies I use plain potting soil and fertilize with a low number organic fertilizer at the time of planting, and usually again when the plants begin fruiting. I never use fertilizer added soil. The percentages aren't the ones I want of the three elements.

So maybe a better option will be to use the regular miracle grow potting mix for faster drain and maybe some all purpose plant food ?

Unless the potting mix has slow release fertilizer incorporated into the mix.
You won't need to add any other fertilizer. The notion that plants need regular feedings even when growing in a good potting mix is simply not true.

It all depends. Your plants will let you know if they need supplemental feeding.

There is already fertilizer in that soil.
