growing sweet peas

[informashun]

I have potted up some 50 seeds for next year .this is my first attempt.
I have followed instructions and read up on the net.
i am confused re when through and about 2" tall.
half the experts say pinch out the tips but the rest say best to leave as stronger plants will result.
anyone got first hand experience?
thanks in anticipation.

I usually pinch out the tips of mine when the plants are about 4" tall. This will encourage bushier and stronger plants. Unless they become too leggy over winter I would wait until spring before doing this, sometimes the frost knocks the plants back a little and I find it safer to wait until growth has resumed before doing this.
