When to fertilize?

[SMB]

What is the best time to fertilize, fall or spring? Also what type to use for both times? I am asking this for a customer, as we don't fertilize yet. Thanks!

I fert. 4 times a year, but if I had to only fert. once a year I would go with spring.

I fert 5 times/year for my customers. Most guys I sub to, I fert 4 times.

In northern turfgrass, if you only fert 1x/year, do so in the fall.

I agree with Lazer. Grass will grow in the spring even if it never gets fertilized. Spring time is when about all lawns look nice and green.

I am not sure where you are at but go to http://www.agry.purdue.edu and they offer some good advice on this.They give in detail what you should be doing every month for a Indiana lawn, great info from Purdue.

THE BEST TIME TO FERTILZE TURF IS IN THE FALL.IF THE TURF HAS HAD A TOUGH YEAR INSECTS, DISEASE AND DROUGHT APPLY AN ALL PURPOSE FERTILZER SUCH AS 19-19-19. IF THE TURF HAS DONE WELL WITH ADDIQUATE RAINFALL APPLY A GOOD WINTERIZER.
IN MY LAWN CARE PROGRAMS I APPLY A 15-0-30. THIS WILL NOT PUSH LUSH GROWYH GOING INTO WINTER. BUT WILL PROMOTE GOOD ROOT GROWTH AND ENOUGH N TO PROMOTE GOOD CARBS AND SUGAR PRODUCTION. NOT IF YOUR IN THE MOWING BUSINESS, APPLING A HIGH NITROGEN FERTILIZER IN THE FALL CAN CREATE ALOT OF UNWANTED TURF GROWTH NEXT SPRING. DO YOU WANT THID SINCE THE TURF GROWS PRETTY WELL ON ITS OWN IN THE SPRING.

Rodney,
That was great info and I'm not trying to be a smart grA** but ALL CAPS ARE HARD ON THE EYES. And I am serious about the great info in your post. Thanks .

15-0-30 is probably the best fertilizer ratio for fall.
