Hi all so i have some chilli seedlings in some jiffy pellets that need to be repotted. Do i wait for roots to emerge from the sides or pot before they appear. Secondly what would be the ideal mixture to plant into? I have vermiculite, perlite, worm castings, bone meal, potting mix, compost and coco peat to make a mixture.
Will then also fertize with a water based nitrogen fert once 3 to 4 sets of true leaves appear.
Thanks in advance. .
Hello, DeanO,
I personally never had experience with Jiffys but I'd get them into potting soil as soon as I had nice cotys.
WIth only those ingredients I'd simulate sphagnum moss by mix addind vermiculite to the coco peat. Coco peat drains a little to quickly to be my main water retainer though I've used it as a more or less pure hydroponic media similar to
@Blister. So the vermiculite becomes the water retaining ingredient. I'd start at 50/50 and make sure it was good and damp after a few days but not soggy and adjust as needed. This will be 50% of your base mix.
Next, you need a nutrient base at 25% of the final base. You could just use your straight compost straight up assuming it's half way decent but hedging with 50/50 of worm casting is what I'd probably do. If you don't use the worm stuff here at least put a cup or two per cu ft into the final base mix as a nutrient.
Finally the base mix has to breath. Use 25% perilte and you're base is done. If the mix feels mucky, add a little more perlite or even coir. If it feels too fluffy, add more compost or worm poo. Those percentages are ballpark numbers, varying some won't hurt.
I'd stay away from the potting mix unless it was a highend mix, like $20US per 2cf bag, with good reveiws.
The cheap stuff at the big box stores in the US is usually garbage and should be tested before committing a season to it.
I don't use bone meal much, but a few tablespoons per cf should be plenty.
I tend to use Epsoma Plantone, kelp, or alfalfa pellets these days to add fertility to a base mix, but it takes a while to "cook" these into the mix. The worm poo is an EXCELLENT amendment, but a liltte variety is best. If you need to plant right away maybe some liquid organic product a little heavy on the nitrogen side is the way to go.
Good Luck!
