Compost for bulbs

[Harald-Alex.]

Thank you - Harald-Alex! I cannot find a source for it in the UK though.

Hallo Anne, a probe of Leonardit for testing with Zertifikat is on the postage-way!
Greetings Harald

I met a guy this afternoon who grow his bulbs in pure zeolith, feeding each 3 weeks.
Seems to work well with Narcissus, Crocus, anemone and Ccilla.
He fails with tulips. It stays humid one week even during a sunny week under glass.

My results with seramis are pretty good with Crocus but i never tried with other genius.

Mineral soil works well with bulbs but it needs more often fertiliser.

I keep Rain lilies (Zephyranthes) in common hydroculture: Clay pepples and fertilized with a ion exchanger every 6 months. They do well and flower the same way as those in soil.

I think of hydroculture as the same moisture levels all year. Does that mean you never reduce your rain lilies water availability through the year?

Yes. And they do not go dormant all through the year. They flower only in summer but they're green in winter too. As they're tropical plants I do not think that that is unnatural.

Preparation of the substratmix for bulbs: Compost and sandy soil as basis plus Seramis or Lavasplit (orange), Stockosorb (white) and Leonardit (anthrazit-black) bevor mixing. Organic nutrients are given after planting on the pots.

you add Stockosorb ? it doesn't retain too much water?

Even the compost is pretty!

Hallo Yann, Stockosorb I use only in small amounts and mix the pouwder quickly with the substrat, so Stockosorb don`t clumb. Only for this foto to demonstrate the ingredients, I concentrated Stockosorb in four places.
It holds the substrate moist, but not wet! Greetings Harald

Hallo Annew, with this ingredients the substrat for the bulbs will be soft, moist and with a good drainage too! Also in dry conditions bevor repotting the substrat is not hard, as former mixtures!
In the foto You can see ca 60 new Galanthus varieties in waterplant-pots and some other bulbs in hard pots for our 1. Springbulbshow next march in Torgau.

I have tried out the sample you sent me in different places. I divided some pots of narcissus into two and put added it to one of the pots to see if there will be any difference. I will be interested to see the results!
