In reply to CD Greier. CD, No, the soil blocks do not fall apart. You do need to get the soil mix right and pack the soil block maker firmly as explained in the article above.

Don’t the soil blocks crumble after a good watering?

In reply to Jessica. Jessica, You are correct. Coconut coir is pH neutral. There is no need to make the adjustment with lime when you use coconut coir. Thanks for your comment. I will update the article to clarify this info.

Thanks for this!
One question I have about the mix: I know Coleman was primarily growing veggies, not ornamentals, and his recipe called for peat. I had kind of assumed the lime was included in the mix to offset the peat acidity (he suggests mixing the two first, actually).
So if you’re using coco coir instead, and growing ornamentals, is the lime still really necessary? There’s no need to raise the pH, right?

Great article that goes into a lot of details most don’t. Thanks!

In reply to Lisa Davis. Lisa, I don't see the usefulness of blocking up to the larger 4-inch soil block. It takes a lot of potting mix and effort to make the block. I do pot up tomatoes, peppers, eggplant into larger containers (plastic cups) until it is warm enough to plant outside. I try to time my other crops when sowed in the 2-inch blocks so they can be transplanted into the garden when they have outgrown the soil blocks.
