Those orchids sound well looked after echt!
My balearica euroatar orchid is flowering its socks off indoors. I had a look at the roots of all of them after the Gardeners World masterclass and think they are probably OK
The plastic boxes have been just the thing, they are 3-4 ins deep with drainage holes in the bottom and everything. Probably had strawberries from the market in Praise hoarding little old ladies.
So this morning I mixed up some compost with perlite and sowed seeds in 11 of the boxes: Salvia patens, angelica, anthrecis sylvestris, calendula, cornflower snowman, verbena bonariensis and heartsease.
I dont sieve the compost just like I don't sieve flour when baking scones, but I rubbed it well with light fingers and decompacted it so it was nice and crumbly and that seemed to help the texture. I wasn't quite sure how much compost to put on top of the seeds when sown and so sprinkled about half a cm worth and patted it all down lightly as Monty seems to do only he has a wooden patter which is very neat.
I didn't soak my seeds before sowing , though I do with sweet pea seeds. What does every one else do?
Also, how thinly do you sow them? I sowed about 12 seeds in each box.
Also, do you water from above with the sprinkler on the watering can or do you put them in a shallow tray of water to soak water up from below?
