Fertilizers and Pesticides Longevity (synthetic and organic)

[mujacko2002]

Mabuhay!

I hope everyone is in A-1 condition including their families and plants. Anyway, i've been thinking about this stuff for awhile regarding ferts and pesticides. I would want to know your honest opinion/suggestion/advises on my inquiry.

I've ferts that are around 4-5 years old and its only been lately that i am using them somehow religiously on my orchids. And the only pesticide i have right now is a neem-tree based pesticide, and maybe i have it for around the same time too. Mostly the labels on the bottle have already gone or faded so i have no idea what type of fert it is but i am sure it is not a pesticide.

Anyway, my question is, would there be a time limit for this ferts to be considered at their prime? i have been taught that the longer you have the ferts the more it becomes effective or at least the potency stays that same. I don't remember any expiration dates on my ferts and pesticides when i bought them. Anyway, i am leaning towards buying organic based ferts and pesticides in the future.

I thank you in advance for any response.

Godbless

PS
For you, how old are your ferts/pesticides?

I believe your fertilizer should remain stable as long as it is kept tightly sealed and in normal temps, etc... Pesticides do not last long around here because they come in such small containers they get used-up quickly, so someone with experience keeping them longer will hopefully answer. (My guess is that if the container is closed tightly and the temperature, etc are within normal range (no extremes) they would also last, but really I am not sure.) Organic items will probably expire or loose their potency over time as they break down - but again, just a guess. I await the science minded members for the 'correct' answer.....

cheers,

hmmmm No idea with that Uly since this month is the first time I ever used an fertilizer/insecticide in my whole life and plant care career. hehehe Lol
But to be serious, maybe they were just the same as other chemicals and medecines that in the long run, potency and effectiveness degrades even if in the best possesion.
