I'm sure the leaves and flowers will bend round the upper ones and find their way out. If one of the upper layer ones gets pushed up you can always put it back.
I wouldnt deliberately do it, but am sure have done in the past. The bulbs all come up fine. They will find their way upwards no problem. J.
Wouldn't worry too much about it, I always plant largest bulbs at the bottom like daffs, then slightly larger ones such as tulips and then the smaller ones on top. They all always find their way up to the surface
yes ,trying out this very year,so far so good at least ,Have daffs coming up as I type.
They do this on Beechgrove, and they have no trouble with bulbs being above other buls as they say the lower bulb will grow around a bulb above it to get to the surface of the soil.
A sink is just a big pot. Just leave the plug out for a drainage hole, and put plenty of crocks or large gravel in the bottom for drainage.
I always plant my tulips in pots in a jam-packed double layer... fantastic show for one year, but don't expect same show following year, so I bin them and start again.
In bulb layering the first flowering bulb goes into dormancy , it won't need water where as other bulbs would need. Then how to water the pot?
Bulbs go completely under the soil and buried so that the soil or compost above them is twice the depth of the bulb itself. Shoot end upwards, root end downwards but they find their way if you can't tell and get it wrong.
Iris rhyzomes should be planted on top of the surface, anchored by their roots. The rhyzome needs to be baked by the summer sun to get the best flowering next season.
I think we need to know what sort of Iris you've got Theresa
I planted exactly like you said and my pots flowered amazingly from February to now, still some pansies in flower. I want to repeat this in October, but should I tip the bulbs out and sort them or leave them in their pots and iignore them?
Can I ask is it better to change compost each time you are putting new plants into pots?
If you have enough of each to fill a pot I think they look better as single varieties. That way, once the iris die back you could plant a top layer of summer bedding such as pelargoniums but if you want your iris to flower again, you need to feed them and leave the foliage for at least 6 weeks to feed the bulbs for next year's show.
The others will flower later so maybe put a layer of pansies or other hardy bedding plants to extend the season while you wait for the bulbs to come through and flower.
