Next year, how long would it take for annuals that are 4 inches tall, to grow very wide, and largE?

I bought this little booklet about Annuals, and there is a colored flower bed with all annuals, like zinnia, begonia, sage, impatients, petunias, periwinkle, and african marigold. On the cover, the bed is very full, with no space in beween the flowers. It shows a step by step instructions on the side of the page on how to make it look exacly like the picture., and your supposed to plant the plants about 5 inches apart, and the flowers are still small when they are planted. How long would it take for them to be about a foot wide, and tall? When would I have to plant them next year? All the flowers in the pictures look very full. thanks.

How long it takes for them to get bigger depends on the plant and growing conditions (weather, soil, season, etc). You would have to plant them after the fear of frost is gone, and they should continue to grow (size %26amp; height) until the cold weather comes in.


Annuals do not return year after year, so each spring you would need to go out and replant everything. If you are putting in a bed for the flowers I would suggest going with Perenials. Each year they will return and be larger until the reach their maximum size. You can add the annuals each spring to give you more color and blooms through out the seasons.
Reply:your looking at the very least 2 months.possibly all summer.it depends on the soil the light they get.and the fertilizer you use.you can get seeds from annuals when you deadhead the flower.make sure they are completely dry before storing them.then start them indoors,or wait untill the last frost to plant your seeds.
