How much time needed to start tuberous begonias indoors?
Q

My tuberous begonias tell me when they are ready to grow. I will put them where I can watch them, in a wire basket with room to keep them apart. As I notice the buds develop I plant them, buds facing up with little or no soil covering the buds. Keeping the soil damp, not saturated, inside in good light. I have never paid attention to the time spent inside before putting out in a protected place. Most of mine are planted now. If I wanted to delay them growing, I would keep them cold. Al

Go for it. You never know how winter is going to end up. It could be like last year and everything will be fine... Or like the year before ad we get early and severe frosts. Either way some flowers aren't much to lose... You never accomplish what you don't try!

What is best time to start planting tomatoes, zucchini, etc?

Using raised beds and black plastic to get the soil warm, I've gotten tomatoes in the ground as early as May 7th with decent results. The thing is, early in the ground doesn't always translate into early tomatoes since tomatoes use soil temperature as well as air temps to get going and without the soil being consistently warm, they just sit there. Also, we seem to get a couple of really cold clear nights around the full moon of each year and that requires a bunch of wall-o-waters or milk jugs to protect the plants or they freeze. I guess you have a choice as to which is better - potting up / taking a chance that the plants will become root bound or planting soon with some black plastic and maybe having to use row covers and other methods to deal with a late frost. As for me, I normally plant whatever weekend is after the 15th of May but I may try to plant 1 of a couple of varieties this weekend and the others nearer the end of the month and check to see whether there's a difference in a month. I'm up on a hill in New Paltz and agree with tommyr that Memorial Day is safest.

You'll find many more details about all this in the FAQ here on Growing from Seed and on the Growing from Seed forum. But basically as soon as they germinate you remove the domes - most don't even use them - and take them off any heat mats used. Leaving the domes in place and on heat increases fungal disease issues and generates leggy seedlings with weak stems and poor circulation systems. A few of yours are already getting leggy and may begin to lay over so dome off ASAP and increase the light as much as possible and as close as possible. When you transplant them to individual pots be sure bury all that stem up to just below the cotyledons. Dave https://www.gardenweb.com/discussions/2766771/how-do-i-start-tomatoes-from-seed

Many of the items on your list can be winter-sown outdoors now! I would reserve the space indoors under lights for the tender annuals or those which cannot be winter-sown.

Check out the Winter Sowing Forum for more information on this method.

By winter sowing outdoors, you mean? Sorry am a newbie to all this.

Yes. Winter sown seeds are left outside to fend for themselves. Check out the winter sowing FAQ for more info and a complete How-to guide.

Yes, and some of those seeds will benefit from or need a period of cold to help break dormancy. So winter sowing will provide this in your zone. Most perennials won't bloom until next year anyway. So you really don't need to get them going as early as possible (or do you?). Do you have seeds of all of these already? Your list is so large. Can you narrow down to a few must-haves?
