Lovely foliage but absolutely no flowers on my cosmos grown from seed this year...should I blame the weather?

    That rather depends -have you been feeding them at all?-if so-with what?

    Not really, just put some in the ground and some in pots. Usually they are easy and perform very well but not this year.

    These are usually my fail safe plants but this year they are only 6 inches tall with the smallest flowers, I am blaming the weather.

  • I know what you mean I grow mine from seed  and was late putting them out because of the cold and wet. I  think it is the weather ,the ones in the sun (when we get it) are flowering they are about 45cm high but very thin ,the ones that are in part sun and cooler damp conditions are bushy but only a few buds . Have patience they still have time mine usualy dont come into their best untill late Aug and early Sept.  Did you watch Gardeners World Monty was planting cosmos,they were only stragly things .Lets pray for warmer weather

  • My 2 cosmos are about 30cm high, the ones I actually sowed never appeared and these are self seeded. not holding out for an amazing display image

    My Cosmos are just starting to flower now which is late for them, I wouldn't worry too much and just hope for more warm weather to spring them in to life. As said above they are much bigger this year than normal.

  • I bought a packet of dwarf cosmos this year as in previous years they have grown too tall for where I wanted them, these should have been 18" to 20" tall. They are now 4ft tall and so bushy they are taking over the garden, just coming into flower. I  pinched out the tops when they were about 8" tall but that didn't' stop them, they are like triffids! Hopefully when they are in full flower they will be a picture, I'm sure unusual season is to blame, either that or the packaging was wrong. I have got some nice neat ones in the front garden self seeded from last year, you just can't win.

    I sowed free seeds from the front of another well known gardening magazine (sorry) and then planted out the plugs in my wildflower lawn. I hoped that they would give some extra colour as this is this areas first season and the perenials won't give much this year. I have to now apologies as they are doing very well and flowering nicely also.... They look great dotted around between the corn flowers and poppies etc!!.... I have to say that they seem to be enjoying the wet weather and of course no worries about watering them!! image

    I sowed mine in March and they are just starting to flower now. I grew Sensations and the tallest ones are already 4 feet tall, I guess the weather is to blame for lack of flowers.
