Would you be weary of mulching your indoor pots with some outdoor comfrey/yarrow/herbs? I thought about giving them a heavy spraying off with some plain water, then a neem/alcohol spraying or 2 before mulching with them. Sound like a bad idea?
Other than barley straw,vermicompost, and plant trimmings...I haven't really mulched like I think I should be. Of course the rest of the comfrey and stuff will go to the worm bin and eventually make its way in anyhow! Do you treat your vermi for pests before using it?
My vermicompost usually sits out thru the winter and I switch to another bin and start on the new bin in late fall. In the spring after the thaw I start harvesting the vermicompost from last years bin. No insects at all, just almost all worm castings.
Thats how I do it. Our Bins are 175gal and 125 gal. We don't fill either of them up totally and rotate each spring. If that makes any sense. By switching in the late fall all the insects have done their job and either moved on or died. Insect frass is a good amendment to soil and compost.
For comfrey, you can just top dress with leaves. The leaves will break down in a 3-5 days. Comfrey doesnt have a lot of issues with insects. If you're worried about spider mites or russet mites you probably bring them in on your shoes and clothing. Nothing really to do but develop and IPM regime.
Which reminds me time for my weekly IPM spray.
IPM spray weekly maintenance treatment. which means I'm bug free for now.
Recipe:
1gal filtered water
1 tbs Monteray Insect spray
1/4 up pure coconut water (no preservatives no sugar)
1/4 cup HorseTail Fern tea
1 tps - Pro-tekt
1 cap full - Ful-power
1/4 cup kelp tea (either reconstituted from kelp meal OR the dried mixed with water)
All that in sprayer and shake well. Foiler top to btm & btm to top all plants soil surfaces and stems and branches even the floor and walls. Everything in the flower room and I'm doing this on the VEG plants as well.
1x a week until we get pests then its every 2 days for 3 weeks and up the Monteray spray to 2-3 tbs. Then back to the 1x a week after bug free for a week.
Nothing on seedlings until they are hardened off.
I don't mulch that much. If anything I'll scratch in a few tbs of malted barley ground fine, cover it will some worm castings/compost and water in.
I'd do a lot more top dress if I was in LARGE containers. Mainly to keep the soil moist but there are other advantages as well. Basically mulching is a form of composting. So why not just add already composted material as a top dress??
I mainly add most all of what I would use for top dress, I add to my compost bin. I also add in amendments to my compost bin including everything I mix into my soil mix including a cup or 2 of rock dust every few months. The rock dust really helps the worms make small work of the composting materials. It speeds the process up quite bit.
It's my mothers that I need to pay attention to for top dressing. They are rootbound most all of the time so they show signs of nutrient deficit before any of the other plants. Not that I have much of that (knock wood).
The mothers of the DT actually turn colors. I have 2 phenos, one gets gold leaves and the other gets reddish gold and some purple leaves when they are hungry.
It's weird they go thru the colors in VEG 20/4 just like the flowering plants do but there's no flowers. Those colored fan leaves on the mothers fall off too just like they do on the flowering plants.
