A question from a fellow grower:
having trouble with all the plants growing at present. the appearance of the plants looks like heat stress, leaves curling in along the edges. they are all growing indoors from cuttings to about a foot high, then they are put outside where they usually do very well.
now the leaves most affected are the young ones, they are curling up as they form. the older leaves look virtually unaffected.
we wondered if the plants, being all clones, may have been getting to the end of their natural life. but we planted out about a100 seeds which all took, & initially were looking good.
2-3 weeks later they too are taking on the appearance of all the earlier affected plants.
the plants are all fed well, not overfed. deficiencies are seemingly not the problem.
BUT! poisons have been used around where the plants are located,(metsulfuron methyl-----triclopyr------picloram) to be specific.
it is well & truly in the soil all round the place of early growth. but has never been actually sprayed around the same area. apparently the soil was placed around the growth area, & the soil was saturated with the stuff.
the air intake fans are very,very close to the soil, & we are wondering if gas off from the soil might be doing the damage.
are you able to enlighten us to the problem/causes? and are you able to give us advice to correct the situation?
all the above details, re poisons etc, are just our thoughts on what it might be that’s affecting our plants. we aren’t positive about it, it’s almost the only thing we could come up with after weeks of thinking about what the hell was going on with our plants. and then the new seedlings all started curling up as well.
