How do people keep climber seedlings under control ?

Withouy stakes to climb they tie themseves in knots. Give them stakes and
they immediately prefer their neighbour's stake - and still get tied up in
knots!

My Mina Lobata seedlings are just reaching the naughty stage now. Lots more
seeds to go in tomorrow - morning glory, chilean etc. etc. so in a few weeks
time I'll have tendrills everywhere.

Thanks

Mike
