Lettuce Problems

[Spookyville]

First time for lettuce so unknown territory...


We have some lettuces in the greenhouse, and a couple of problems. Firstly some of them seem to have rotted at the root (where the leaves meet the soil). The plant then wilts and dies.

Secondly we seem to have aphids on some of them - some reddidh some white some green. Not sure on what type etc..
We are trying to be organic but I am nervous the little critters will hop onto my toms whixh are now underway in the same greenhouse.
Is there a quick easy spray solution (just this time!) to zap them???

TIA

try the garlic and seaweed spray, boil half a bulb of garlic in half a pint of water, crush when soft, seive..you can use this when it goes cold on it's own , we mix it with a seaweed liquid so's we feed at the same time..you can also buy soft soap spray or derris spray, both are better than pest killer sprays.. :)

I would move them out... and let the ladybirds clean them up!

the ones rotting off, are they in the ground?  :)

[Spookyville]

no they were in pots about to be transplanted into a growbag..

that makes it a bit difficult, could it be overwatering?..ours seem to be quite strong, the only things that get them..but they're in the ground..are slugs and cutworms..any ideas, anyone ?

My guess is they are too warm and not getting enough ventilation so you could well have developed botrytus.

Plus you have created the right conditions for aphids.

My only advice would be is to get them outdoors in a well lit sheltered spot and see if they survive.
