Author Message   Linht  Posted on Sunday, March 30, 2008 - 09:38 pm EST :    Hello, I'm a new member here and just have a few questions about the 10-20-20 fertilizer. In one of the other posts it talks about using 1/2 cup of 10-20-20 before planting. How much area does that amount cover? Or is it 1/2 cup per plant? Also, if I cannot obtain 10-20-20, could I use 6-10-10 and just double the amount? Is that close enough?

Once when planting & once again as a side-dress at the end of July. I don't think I'd use twice as much to start but you might have to use it 3 times instead of 2 - just go by what the plants look like. If the green is not nice & rich or the stems aren't holding up the blooms it's time for a boost. The 10-20-20 goes in the hole, is stirred around & some topsoil put in on top of it before planting.

I finally found a feed store 30 min away who carries 10-20-20. Just have to wait for them to get it in stock. So let me see if I got this right..... Mix 1/2 cup 10-20-20 in the hole. Cover with a little topsoil, put tuber on top and cover with regular garden soil??? Thanks for all your expertise & I will NOT miss out on your Moonlight Sonata again next year!

You don't have to go & get a bunch of special topsoil- although your dahlias would probably LOVE it!

Tracy Linht - MN, Zone "4a"   Linht  Posted on Thursday, April 10, 2008 - 01:38 pm EST :    Cory, I finally found a source for 10-20-20!! It is being shipped to me from WA. I received some of my tubers last weekend and the instructions from that grower, specifies not to use 10-20-20 at planting because it could burn the roots??? They said to apply the (10-20-20) 2 weeks before planting. I'm sorry, did I misunderstand your directions? Can I put the 10-20-20 into the soil the same time the tubers go in, or is it supposed to be 2 weeks before the tuber goes in??

That way the fert. doesn't burn the tuber & it takes the feeder roots awhile to grow down to it. If you put the fert. on 2 weeks before planting all the N will be gone by the time you plant & the roots get to it. Cory Plantlady2 - Washington, Zone "7"   Linht  Posted on Saturday, April 12, 2008 - 10:42 pm EST :    Ok, I see. I will print out your directions to remind me and do this exactly the way you described. Thanks, Cory!

I've read that it should be widespread. I'm not sure I understand why that combination is...well...so good. I thought you just throw in some bone meal and WhaLa. Dcrosby - Massachusetts, Zone "5"   Plantlady2  My Favorite Photo My Weather My Garden My Time Posted on Wednesday, April 16, 2008 - 08:27 pm EST :    Hi Dcrosby-Don't know about widespread- but why would you want to fertilize walkways & places where you don't have plants? I guess if you're growing your dahlias in a flower bed w/ other stuff it would work, but we grow them at individual stakes or in rows in the Big Garden & it would be a total waste of fertilizer to do it that way-- not to mention the weeds would LOVE it if we broadcast the fertilizer- & the husband would be out there hoe in hand 24/7 instead of only 18/7 >:) Plantlady2 - Washington, Zone "7"   Dcrosby  Posted on Thursday, April 17, 2008 - 03:12 pm EST :    Hi Plantlady2 OK, i'm on board with the 10-20-20 But what about the Bonemeal? Can you/should you do both? Dcrosby - Massachusetts, Zone "5"   Plantlady2  My Favorite Photo My Weather My Garden My Time Posted on Sunday, April 20, 2008 - 04:01 pm EST :    Don't know why you'd need it- we've never used it but what works for us might work differently for others. Bone meal breaks down very slowly & isn't usable for a long time- like when you put it in the hole for planting tulips or daffs. it doesn't do anything for the first year's blooms but is used for the second year to build up the bulbs & the next year's blooms. It seems like when you dig up dahlias the bone meal might not even have started to do any good. I wouldn't think you'd use both because the 10-20-20 will provide everything you'd need. Plantlady2 - Washington, Zone "7"   Dcrosby  Posted on Monday, April 21, 2008 - 08:59 am EST :    Hi Plantlady2 Hope you dn't mind if i tax your expertise once again...I am unable to find 10-20-20. Here are a couple few combinations that are (kind of) similar 2-7-4 5-10-5 14-28-15 10-18-20 If none of these work than i will continue my search. I think Linht has a source Thanks so much! Dale Dcrosby - Massachusetts, Zone "5"   Eileen  Supporting Member My Garden Journal My Weather Posted on Monday, April 21, 2008 - 09:34 am EST :    I searched for 10-20-20 then realized Cory mentioned it was general use fertilizer for farming. It was easily found in a feed store. Go where the pros, farmers, go. Eileen Pennsylvania Zone 5
