Save my plants

We just got some mushroom compost (looks like from manure and straw).

We mixed it with pay dirt from the nursery to plant a cherry tree and pomegranate tree. We mixed it with potting soil to plant some veggies - tomatoes, cucumbers, spinach, etc.

The veggies seem fine so far, not great, but the trees aren't looking good. The blossoms on the cherry tree dried up and the tiny pomegranates look dark and dried out. We planted them all last weekend. If it is because of the compost is there anything I can do about it now? Would it be better to dig out the compost now? The compost is mainly on the top of the trees.

It sounds like the material might be still too "hot", ie, not completely composted, which will burn the roots of many plants;

I'd scrape away the compost & drench the trees & plants, roots, stems, & foliage.

What other variables are there besides soil? We've been having a heat wave, have you? That always stresses newly planted trees/shrubs. If the planting medium smells 'fertilizy', then that might indicate incomplete composting ... if it smells 'earthy', then I don't think they are suffering from root 'burn'. And besides, I think that the vegetables would show root burn more readily than a tree. Another thought ... sometimes nursery/potted trees/shrubs have been water/heat-stressed before you got them and the added stress of transplanting is the final straw. Hope your plants spring back ... probably no fruit this year, but next year!!!

.... odds greatly favor the problem being a drought response due to either a high level of soluble salts in the soil (especially if you fertilized) or impaired root function brought about by excess water retention in the mix you described.

Sounds like transplant shock to me. The larger the plant the more transplant shock will take effect, hence just the trees. I think they'll be fine once adjusted to their new home. If you planted in the ground then your mix would not be too water retentive but if in pots, that's a different story.

I thought that fruit trees should be planted when they were dormant, not when they were in bloom.

I think you are right to blame the mushroom manure. Last year I bought some bagged manure stuff from the store and used it mixed with potting soil in 2 pots in which I planted 2 trees. They suffered for months until finally in August they put out new leaves and began to grow. I'll never buy that stuff again.

I didn't realize mushrooms defecated??
