I have some questions about this plant too. Is there any preparations that need to be done to the seeds? I have the seeds but when I planted some nothing happened. Jessica

It is always best to start seeds outside. Right now though in my area it is to hot to start anything. Seeds like certain temps for germination. If you were to move your seeds outside now you will need to harden them off. That means that you will need to slowly get them use to the different atmosphere that is outside. In regards to the wilt it could be several things it could be a pest. It could be lack of water. It could be to much water. I try my hardest to always water any of my seedlings from the bottom. Seedlings outside take more water than those that are inside. I am not familiar with a cocount husk planter, but any planter needs venting holes at the bottom. I would suggest maybe putting your husk in something like a bowl or a shallow dish of some sort, place your husk in a window, water by adding the water to the dish. As the water dries up then add more water if your leaves start to turn yellow slack up on the water for a few days. This advice is given as thinking that your plants didn't suffer root rot. Look at your seedlings closely if they look like they have been actually pinched, then sorry there is no hope. If there is no pinch mark then your plants are only wilting for the lack of water and sunlight. Here is a link that might be useful: How to harden off your plants

no pretreatment needed. pH not important. well drained soil is. lightly cover the seed soil temp 70-80F & takes 7-10 days to germinate. May start inside now or delay planting outside till summer

No sand in the soil...topsoil and mulch in that area. So it would stick...it maybe actually 3yrs. Not sure actually...left one because ones always ask for seedlings. And I pull typically pull them out. This year...I plan on deadheading before seeds are sewn. Lol Ken...you have a real love for Rose of Sharon. Thanks for your knowledge much appreciated. ~Darlene
