Gradually, over the course of a week or 10 days, expose them to more and more sunshine and wind. About a week before you plan to set the seedlings into the garden, place them in a protected spot outdoors (partly shaded, out of the wind) for a few hours, bringing them in at night. You’ve been coddling these seedlings for weeks, so they need a gradual transition to the great outdoors. It’s not a good idea to move your seedlings directly from the protected environment of your home into the garden. As the seedlings grow taller, raise the lights. Keep in mind that seedlings need darkness, too, so they can rest. If you’re growing under lights, adjust them so they’re just a few inches above the tops of the seedlings. Rotate the pots regularly to keep plants from leaning into the light. If you’re growing in a window, choose a south-facing exposure. They never sag as a pine tree or spruce would. Set the lights on a timer for 15 hours a day. If you take a look at these very mature trees you will notice that the oldest branches grow up and stay that way.
Remember to feed the seedlings regularly with liquid fertilizer. Let the soil dry slightly between waterings. When you see the first signs of green, you have to remove the cover.Īs the seedlings grow up, you have to keep the soil moist but not soggy. All three Redwood species are considered endangered, but the Dawn Redwood was actually originally discovered only in the fossil record. This helps keep the seeds moist before they germinate. The Dawn Redwood ( Metasequoia glyptostroboides ) is native to China and is one of the three surviving species of Redwood Trees, the other two (which we also sell) being native to California. To speed up germination, cover the pots with wet paper or a plastic dome.
After planting seeds, you have to moisten the newly planted seeds. Some of the small ones can be sprinkled right on the soil surface. Start with a fresh, sterile mix that will ensure healthy, disease-free seedlings. NOTE: Do not use soil from your garden or re-use potting soil from your houseplants. If you love to DIY by yourself, you might start growing seedlings in yogurt cups, milk cartons or even a paper cup.Ĭhoose the potting soil that’s made for growing seedlings. You can start seeds in almost any type of container, as long as it’s at least 2-3 ” deep and has some drainage holes.
