The most important things to remember with planting rambutan seeds are: 1  Seeds must be put in flat. If you put them in with the long side going down, then they will almost surely die. 2  Don't bury seeds too deep. Just push them into the dirt and brush a bit of soil on top of them. 3  Soil must be kept loose.
Sunflower seeds are best sown outdoors directly into the garden. After planting, cover them with a screen, as the birds and animals love to dig the seeds out. You can also start them in a seedbed and transfer them when they are small. If you plant sunflowers indoors, use individual peat pots. Start two to three weeks before the last frost date for your area. Plant one or two seeds per pot, thinning to one before planting outdoors. If you grow them to feed the birds, look for seedlings growing near the base of last year's crop.
