How to Plant Nemesia Seeds

Plant Nemesia seed in peat pots about 7 weeks before your last frost date. Wet the peat pot before placing the seed in. Cover the seed lightly with vermiculite. Water by placing the pots in a shallow tray of water to dampen the peat pot and then remove. The pots should stay damp but not soaked.

Keep the pots in a temperature between 50 and 70 degrees and the seed should germinate between one and three weeks. Once you have seedlings, place them in an area that gets filtered sun or some light.

Prepare the soil in flower beds by digging or tilling a few inches deeper than the peat pots. Remove half the soil and amend it with one part peat moss, one part builder sand and two parts compost. Fill the area with amended soil and rake smooth. This will create a rich, well draining soil. For containers add a couple handfuls of compost and a handful of sand to your potting soil. The location should be in partial sun to a shady area.

Dig a hole large enough for the peat pot in the soil. Break off any lip from the peat pot that will cause water to sit around the seedling and bury the pot in the soil so the crown of the plant is at soil level. This should be done in early spring after all threat of frost is gone.

Place a slow release fertilizer around the plant on the soil. Fertilizers should not touch the crown of the plant. Follow manufacturer's directions on the fertilizer you choose for amount and how often you should apply.

Water the plant deeply to help establish the roots in the new soil and to release the fertilizer. Then water only when the top of the soil feels dry.

Pinch back tips of the plant while it is young to promote a bushier plant. Deadheading flowers is not necessary with a nemesia.
