How often should I feed my outdoor plants

[Koro1973]

I have 30 plants in 30litre plant bags and have only feed them twice ...how often should I feed them?...they are all in canna Terra soil mix...

They look great! As far as how often to give nutrients, what are you feeding them with?

[Koro1973]

Because of finance I'm trying to do this one cheapish without being to cheap...so I'm using grow zilla liquid nutrients...a and b ...for vege....I've used this with hydro set up before and was really good...but outdoor is a lot different...lol...I'm thinking I can probably get to them once a week...and gAve them 1 liters each last feed...I do have a control plant at my house to sort of help me with what my happening with the others and I guess it's growing pretty much the same as the rest...

I like to micro feed every time I water. This can get quite involved when feeding more than one product. Sometimes in the summer when it is 105 degrees I need to water every day. Then I cut back on nutes. Once a week will do.

[Koro1973]

It can get quite hot at times but normally temperature range between 22 - 30 degrees Celsius
So maybe not the hot u guys are use to...it's working out to be about 300 liters a pop at the moment and it's only just gone onto summer

So it sounds like your grow site is not near your house. You have to drive to get to them? How do you transport water, and do they also get rain?

[Koro1973]

Yes they are not near my house. ..I have 3 x 120 litre barrels with lids.which I transport by trailer. ..have access to some farmland with no one around for miles...it does get rain here...which is really good...maybe once a week...but I don't have any ferts in my soil and want to give them what they need from my nutrients

They way i have always done it, is to feed enough for the slightest nute burn. If or when i see nute burn, especially if its happend so soon after the first fert. I will cut the time between feeding down, sometimes stop completely. The plants will benefit more being slightly overfed, but too far and you will hurt growth. How often you fert will depend on the plant, age, soil etc. Feeding with every second watering is a good start, close watching will tell you wether you need more or less. Bad soil can have you feeding every couple of days, great soil can have you never feeding it. Its all about watching and hearing what your plant needs.

This is the control plant...actually . ..I have topped this one and cut leaves off her...so I guess the only thing that is the same is the feeding of them

Once a week seems good to start, and like Dan said, you want to use less if you start seeing nutrient burn. If the whole plant starts getting pale with yellow leaves at the bottom, it means they need more nutrients Your plants look incredible with perfect color right now so they obviously like what you've been doing so far!
