Allium leaves turning yellow

Last year, my giant Allium flowers were big & healthy; this year the tips of the leaves are turning yellow -- last year's are looking half eaten or something & drying up. Now my new bulbs' leave tips are starting to turn yellow & dry. Help!

Doug says that old leaves should turn yellow as they're dead. They only last one year and need to be removed.

If the tips of new leaves are yellow, it is possible (probable) that you're overwatering. This can lead to rot and yellowing tips.

If the yellow is streaky down the leaves (compared to a yellow tip only) then your bulb has a virus and should be discarded.

Sometimes allium leaves will be yellow in early spring if they've been frosted a bit. You don't say where you're from so I can't tell if this might be true.

Alliums need great drainage and open soils to thrive. If you're trying to grow it in clay soils, then you're going to see problems like this with water retantion.

Hope that helps a bit.
