Depth advice

Evening all


i have some purple sensation allium. Some that are half purple half green and some hiacynth bulbs.


my question is, how deep can I plant them. I would like to leave them in but worry I may dislodge or dig up when putting bedding in.

    I tend to go with at least twice the size of the bulbs. I have planted crocus/grape hyacinths deeper than that and they always seem to find there way through.

    I think with the larger bulbs the deeper the better as I regualary disturb a lot of the smaller ones, I just chuck those ones back in

    I put my purple sensations in about 5-6 inches deep - they come up each year, but get a bit smaller each time, so i plant a few more every year to top up.

  • Do I need to put grit in the planting holes as my soil is quite heavy. 

  • Verdun what is mpc??

  • Chicky , there must be a way to feed alliums to keep them big. Not sure what it is but someone will advise.

    Perhaps if you feed as they emerge, they will put on lots of growth which will then feed the bulb as it dies down later. 

  • Monty D's always seem to grow and be a show I hope mine don't die off. Just waiting for the dahlias to need lifting, will then set the allium and hyacinth .

  • I have quite a lot of roses and rose feed is not cheap!!  At a recent hortisoc talk by Stewart Pocock ( of Pococks roses fame) who is local to me, I asked for his advice on how to feed a lot of roses economically. He said he sells 25kg. sacks which in the long term must be good value. I will be putting some on my alliums as well as my roses, and other favs. as well.

    Good thought Woody - maybe will try with liquid seaweed when i do the rest of my bulbs next year.

  • Is tomato feed made from seaweed?

    My problem with Purple Sensation isn't keeping them big. It's keeping them.

    A christophii stays and multiplies as do various others. Purple Sensation never
