#damping off

[lynnafred]

Remember the post I made about a month ago, about thiram and how it can help keep seedlings from damping off?

In that post, I explained what damping off looked like: typically in a circular pattern, caused by a mix of a few different fungal pathogens.

Well, today, I have a picture!

This is a tray of early season cabbage, called Tiara. In this picture, you can see where it's started to damp off, and where we've already pulled plants from it. This came on very suddenly, towards the end of last week, and it's progressed a lot since then. It means an off-the-bat loss of 25%, but we've already seeded a new replacement tray, which will hopefully do better!

Happy seed-starting season - It’s the most wonderful time of the year!

satoyama seed starting mix

1 part perlite

4 parts vermiculite

5 parts peat moss (or coir coconut fiber), screened

Enough water for mix to ‘clump’ into a ball when clenched in your fist which crumbles apart easily when poked

Tip! Put your seedling flats in trays so that you can water from below by adding water to the tray (no more than 1/8″ deep).

When the seedlings show signs of true leaves, I transplant them into

satoyama potting soil mix

5 parts satoyama seed starting mix

4 parts topsoil, screened

1 part vermicompost or other finished compost

Enough water for mix to ‘clump’ into a ball when clenched in your fist which crumbles apart easily when poked

Tip! Pour 1 c. boiling water over a chamomile teabag and steep overnight.  Mist seedlings with chamomile tea for a soft antifungal to prevent damping off.

[Blog]Damping Off – Onion Crop Protection at Kay Bee Bio Organics

Cultivating onions plays a vital role in global agriculture, serving as a significant source of income and sustenance for communities around the world. But there’s a problem called damping off. This disease affects onions during their early stages of growth when they are still in the initial phases of development. It’s because of certain fungi in the soil, like Rhizoctonia, Pythium, and Fusarium. Read the complete blog here at Kay Bee Bio Organics blog.

i have no idea how humans managed to transition to agrarian societies because trying to grow anything is a sisyphean endeavor that ends in heartbreak. no i am not being dramatic.

I was told to keep my carnivorous plants in humidity for the first bit.... So I covered them in plastic......... Not realizing that it's already humid af.

Fuck now they're too damp and getting sick from it. Hopefully they survive 😭
