I'm currently growing on cosmos Antiquity and Rubenza in 3" pots. They're about 4"- 5" tall at present but are forming buds already. Do I need to nip these out or leave them on?
Also what height do they need to be before I plant them out.
HI peter. I personally would not nip out the flower buds but I'm sure others will have different ideas. I planted mine out today in containers and they are about 10 to 12 inches tall.
Thanks ladybird4. What is your strategy for growing in pots? One plant in a smallish pot or multiple plants in a larger pot.
Didn't Monty on friday's Gardeners' world reduce the main stem so that it produces more stems and buds? I've never done it, I just let them grow as they are
Hi peter. I have a large container with 9 different plants in. Its my bedding plant container as all my garden is already filled with perennials I like the riot of a full on display so I pack 'em in!
Ive grown Rubenza a few times - lovely plant but gets very straggly. I've pinched my Rubenza's out twice now this yr. Flowers wont be as big but at least they'll not all be on the ground after a drop of rain
I move them from the 3inch pots into six inch pots, and pinch out the tops to make them bush. I plant out quite large plants into gaps in July.
