I would wait until it is 95% dead before mowing. Reason - the dead stuff will mow up pretty easy. When you come to a still-live patch, that mower will bog like there is no tomorrow. Ran into this Tuesday. I think you can do the second ap of Roundup as soon as you can tell what is died or is on its way to being dead and what you missed. I could have done my second ap 5 days after the first once I saw what I had missed but I waited until 7 days after due to time conflicts. And for a second ap, you only need to hit the areas you missed, not the whole yard again.

Some folks sow sweet pea seeds in the fall so they germinate the following spring as soon as conditions are right for them. For spring sowing, plant sweet peas outdoors as soon as the soil can be worked, up to six weeks before the last frost date, which in Rochester should be now. They should be in a fairly well drained soil. -Rosalinda

I grow various Japanese Morning glories. I do soak my seeds, but have never started them indoors. I like to start my seeds sometime in March. They grow pretty fast. I usually sow about 4 seeds in each pot, using regular potting soil. They are not as invasive, although the only MG's I had this year were volunteers from last years dropped seeds. I grow mine in morning shade. You could probably get good information on the vine forum.

After exchanging addresses you can mail your seeds. The seed packs are carefully wrapped with bubblewrap and placed in an envelope or you can use a padded mailer to send them. You need to cushion them in fat packaging so they don't go through the PO's automatic mail sorting machines. Always make sure that your email address is included with the seeds. If the trader needs to contact you later on the email address is right there for them to use. Always write your return mailing address on the outside of the envelope. The post offive will charge a bit more for mailing a fat letter, it is because the letter gets out-sorted into "hand-mail". It's too fat to go through their high-speed mail sorters. The width should always be over a 1/4" thick to keep a letter out of the mail-sorters because these high speed machines can crush the seeds to powder. It's courteous to let your trader know when their seeds will be on the way. If you've promised to mail on Monday, but something happened to delay that then email the trader to let them know when the seeds will be mailed...and keep that date! A good trader is a responsible trader. Good traders use bubblewrap or padded mailers to assure that the seeds are not crushed during their trip through the mail.
