The most important things to remember with planting rambutan seeds are: 1  Seeds must be put in flat.

1. Plant delphinium Summer Nights indoors between spring and early autumn. Fill a celled planting tray with a peat-based commercial potting mixture. Plant one or two seeds on top of the soil in each cell, and then cover the seeds with 1/8 inch of vermiculite.. Transplant the seedlings into individual pots when the seedlings develop their first set of true leaves -- the leaves that appear after the initial seedling leaves. To transplant the seedlings, lift them carefully from the tray with a spoon, and then plant them in 3- to 4-inch pots filled with potting mixture.
