Hi All;


I am growing cauliflower for the first time. Here is what I have done so far:

I used a heated propagator that I bought in B&Q and planted the seeds.
After a 8 days all small plants started to show and after 14 days i took the lid off as i notice the plants were very tall and falling over.

Is it normal for them to fall over or should i plant them deeper into the small trays i have them in?


Any help be great.

Thanks

cant really help - im growing the caulis for the first time also with mixed results. Germination is great, they grow to a size suitable to transplant to single cells and within a week nearly two thirds have collapsed. Any help apprecitaed!

sainttoff and Jimbo, not really a great need for a heated propagator as most cabbage-like veg germinate in or around 10 deg C sown at ½ inch (1cm) deep.
It's very important to take the lid off the propagator during the day so they get plenty of light.

sainttoff , this is more than likely what happened to yours as they went leggy stretching for light whilst being promoted by the heat.

Its time for thinning when your seedlings have produced true leaves, those which are the first set of leaves that emerge after the original germination leaves.
Thin by pricking them out and replant them into small individual pots.

Jimbo, They are better off grown colder (without propagator) as they end up "harder" for it.
I presume yours got a shock of some sort after coming from warmth, possibly a cold breeze or an application of cold water.

Thanks a million for that.

So i kinda need to start again so.

Is there any harm in using the heated propagotor if i do the following:

I use individual seed trays for my seeds, how far do i fill up the seed tray with soil?

Put them in the propagotor and leave the lid on till they germinate and see small plants?

Then water with warm water and leave lid off at day time?


Also what about leeks from seeds, whats the best approach here, i have another heated progator:)

Thanks a million but only learning so want to get this right

Thanks for that. The cold water theory is the most likely cause of my probs so.

Will try again! Smile

sainttoff, fill the tray to within 1cm of the top, firm gently with a piece of board or fingers to remove air pockets. Check that compost surface is roughly level, adjust if required.

Yep, put them in the propagator and leave the lid on till they germinate and you see small plants.
Once your seedlings break the surface, you can prop up the sheet of cover to allow air flow. A few days later remove the cover completely.
Turn the seed tray every few days to stop the seedlings growing lopsided towards the light. Water the compost when needed to stop it drying out.
When watering there is no need for warm water, just room temp.
Use a mist gun rather than a watering can to avoid washing out the seedlings.
Keep an eye on the seedlings and when the first set of true leaves appear then they are ready for transferring.

Sowings of leek can be made as early as January if the seeds are sown in trays and kept in the greenhouse at a temperature of 13 deg C. Keep them in the greenhouse until March then begin to harden them off in a cold frame; they can then be planted out either late April or early May.
Without the propagator you can sow direct into soil in late March
Make shallow drills ½ in. (12mm) deep and 6 in. (15cm) apart, sowing the seeds thinly.
