Agree with all of the above info although I don't find that germination rates of properly stored seed declines by more than 5-6% per year. With few exceptions, 2007 seed, properly stored, should still be quite viable. It definitely wouldn't be considered old seed.

But when we have poor results it is so much easier for us to blame the seeds or blame the potting mix when in truth, most of the problem causes are us - the growers. We insist on too much water or not enough soil heat or failing to scarify or stratify or most commonly, insisting on indoor germination when direct seeding is best. ;)

The germination needs of so many seeds are very diverse so it is best to research the needs of each variety for the best results.

The many FAQs here on this forum (front page in blue link) cover hundreds of varieties and if you Google 'seed germination database' you'll find lots of help.

The information on this database is reliable, a good one to keep bookmarked. Most of the suggestions are for dried stored (i.e. commercial) seed - in some instances seed sown freshly harvested may have different requirements.

The peppers - pinch off the blooms and they will do fine. The cukes however will most likely stunt. I would start new ones of them or better yet plan to just direct seed them - that works best anyway.

Members of that family if transplanted with more than just 1 true leaf produce poorly throughout the season.

A plant is programmed to grow and produce seeds. The leader--top--is boss and the good goes to it to produce seeds. What's left over goes to the branches. If you remove the top leaves and a bit of the stem the plant goes into survival mode and produces lots of stems so it can do what it is programmed to do and produce seeds. These stems unlike the leader are all equal and the good is divided equally to them all, so you get a bushy plant.

Sometimes when we deadhead we do this naturally. Like with Marigolds. Remove the top flower after it dies and you are pinching it back and it produces more branches and as a consequence more flowers.

Pinching ANYTHING is purely optional. It is never required. When in doubt, don't pinch and as other have said there is definitely no need to pinch marigolds.

Your azaleas are beautiful, I've seen the photos :)

Here's the directions for your talented DH, he might just get some interesting crosses. It looks a little wordy but is fairly straightforward, just some warmth and moisture, along with a little patience for these slow growing shrubs needed. Don't cover the seeds, just wet them down to make good contact with the sowing medium. And I'm glad to see you able to turn your thoughts back to gardening, dear friend!

Azalea Society of America -

Azaleas grow readily from seed. The seed pods are plainly visible soon after the flowers drop, and become larger over the summer, eventually turning dark brown, splitting open, and dropping the seed on the ground. Only very rarely will the conditions be right for the seed to germinate and grow in the garden. Instead, collect the seed pods before they open, and grow the seed under controlled conditions. Collect the seed pods as they begin to turn brown, usually around the time of the first frost in the fall.

Put the pods of one variety into one container, such as an envelope or a small paper muffin cup, and mark it with the variety. After a few weeks, the pods will split and begin to spill out their seed, as many as 500 seeds per pod (My note: they are almost like dust!). Clean the seed by separating it from the pod and other debris.

Prepare some flats by putting a mixture of sand and peat or leaf mold or perlite to within about an inch of the top, and covering it with a half inch or so of milled sphagnum moss. Soak it until it is thoroughly wet, and let it drain out the excess water. It may be convenient to soak it separately in a tub of water, and fill the flat with handfuls of the mixture squeezed free of excess water. The plastic containers used by supermarkets for pastry and salads, about three inches high and various widths and lengths, are ideal for small quantities of seedlings.

Sow the seed in the winter, indoors, to give the seedlings as much time as possible before being subjected to outdoor winter temperatures. Broadcast it over the flat and mist it lightly to settle the seeds. Cover the flat tightly with plastic, and put it under artificial lights or on a north window sill. The seed will germinate in two to six weeks, depending on the variety.

When the seedlings have developed two sets of leaves, carefully transplant them into other flats filled with a similar mixture of sand and peat or leaf mold or perlite. Use a toothpick or similar fine instrument to remove a seedling, and to plant it into the new flat. Use a two or three inch spacing, as they will probably stay in this flat for a year or more. When the flat is filled, water the seedlings with a fine spray to settle the soil around the roots. Cover it with plastic, and place it under lights or on a north facing window sill, or outdoors in the shade if the weather is reliably above freezing. After a few days, the seedlings should be established and the plastic can be removed. Fertilize with very weak solutions of liquid fertilizer to maintain active growth.

After they have grown a year, the seedlings are ready to be potted up or planted out. The soil should be almost a solid mass of fine roots, and the soil can be cut into squares rather than trying to find out which roots go with which plant. They are quite tender, and should be given ample water and ample shade.

You guys are great, thanks for the advice. And thanks for pointing out the FAQ's, for some reason I hadn't even noticed that. There is a lot of info that will help.

As a professor, I know that answering the same questions over and over from beginners can get tedious.

No! Leave the healthiest and cut the others off. One plant per cell. The reason 3 seeds are planted is so that you get at least 1 that germinates.

I want to chime in and say how great it is that he is learning through this about the plants so that in the future he'll most likely be such a helper you'll wonder what you ever did without him. Kudos to him for being teachable and willing to admit his helping wasn't quite up to snuff, and kudos to you for nicely teaching him via experience how he can REALLY help! Sounds like ideal gardening partners.

Update. We went out to put the babies to bed last night. They had to go back in the hoop house because the low last night supposed to be 30. My 16-yo looks at the pathetic maters and asked "what is wrong with these?" Before I could speak hubby jumps in and says "sunburned".

By George, I think he's got it!!

I'd move them to 4" pots now, then to 6" pots if they outgrow those. Individual pots are better than putting them together in a big planter and then having to untangle their roots. But I like oilpainter's idea of asking the people who are selling you their house.

Keep them outdoors in at least 6 hours of sun daily. The plants will get leggy and be useless if they don't get plenty of sun and cool overnight temps ... but small pots can dry out easily. If you can't be home to water them on warm days, you can bury the pots in a garden bed up to the rim, and lift them every day or two to make sure the roots don't grow through the drainage holes.

I suppose the big question is whether or not the June 4th move will be to a place where they can go into the ground. What you really want to aim for is to reduce the number of times that you transplant but at the same time get them out of the pots they are in now. The current pots are far to small and will negatively impact future transplants if you leave them much longer. If you are unsure then go for the 6' pots. You can always leave them in there even after you move to a more permanent location until the plants are ready for another transplant. Try to keep them well watered in the meantime to discourage additional root development.

Here is my update. My husband does NOT have cancer. It was chronic/acute kidney failure and he is now recovering at the Gainesville, FL VA hospital which is the best hospital we have ever been in! Thanks to God!.

I have not had any time to do anything. We have been traveling back and forth with a rental car (ugh! $$) and My seedlings have been hanging in there.

I've got the Tomato, Cheyenne Bush Squash, and Yellow Cucumber, Jenny Lind Melon , Malabar Spinach seeds, Summer Squash and some Milkweed seeds started.

I had to put them in small pots because I have not had time to get them into the ground. My garden area is not even prepared yet.

My husband should be out in a few days and I will just have to see what I can do.

I have read on some of the packages that some of them (don't remember which, I'm stressed still) do NOT like to be transplanted, but we will see what God will allow to happen when the time comes.

Thanks,

Halime

PS I have some Wax Myrtle shrubs that I planted last year and had to move during the month of November. They got very leggy and I took the advice of people on here to just "whack" them close to the ground. THEY ARE LOOKING BEAUTIFUL. Nice and bushy and green.

Yay! I'm glad!

I've actually had no experience with most of the plants you're growing (don't know what to do with squash and don't even know what a milkweed is! :)) but I hope everything works out ok with them. I, too, was running behind this year. Sheer ignorance on my part, but I am suprised how quickly my peas and spinach have caught up. Even bought some herbs yesterday.

They shouldn't need any support. If they're get leggy they need more light.

When you bring them in, don't bring them into a heated room. It is better if you bring them to a unheated garage, e.g.; otherwise a process of "reverse hardening off" might occur.

It would take more than just overnight or even a couple days to do that.

Well you're on the right track sleepy but the thought was if the bulbs were higher wattage than the ballasts which would make them under powered. If the ballasts are electronic then putting a lower wattage bulb in them would overdrive the bulbs making them brighter.

And zinnia is considered a little difficult to transplant... not as difficult as poppies, but you still need to be a little careful when you transplant.

But it is near the time to plant zinnia directly outdoor! Yes, you will get it a little later, but you will still have plenty of zinnias this spring/summer. :)

Oh yes, Susan - we have been using Celcius here in Canada for many, many years.

Sarah, the temps. here are unseasonbly warm. We do not usually get these temps. until late May/early June, so I was starting them indoors to get a head start. But realizing that we are already frost-free, it occurred to me that I might be able to try this. Thank you.

tbschemer(9/10)

Maybe I'm confusing nominal wattage with actual wattage. What wattage would I actually be looking for in a 2' fixture over one flat?

I have very little space in my room (it's about 80 sq. ft, with a bed and a desk taking up much of that), but I do have plenty of space out on the south-facing lawn of the building. I can leave massive pots out there and groundskeeping is happy to just leave it alone. And if there's ever any trouble, one of the other dorms has a garden plot that goes mostly unused. It's a little far away, but if I had to, I could replant into the ground there.

Depends on the bulb. T12s are 20w, T8s are 17w and T5s are 14w.

Good Grief! People are going to wonder about the "nuts" in my name............

I meant to say that I could then call a person with a long torso, leggy. Ha! Ha! Now is it funny?

Yes, skinney stems are often associated with leggy seedlings because they are stretched out.

You are correct : )

I liked your example :)
