Can you repeat this reply in the 'answers' section on your original question page. Ta. That way anyone who replied will get a copy of the message and the conversation can continue on one page. Otherwise it's impossible to re-find the question. Go to 'your options' and then 'questions'. Your original one should be there.

I've checked back to follow this thread - yes, you can use Autumn lawn feed and weed and mosskiller. The nitrogen it contains is very slow release so the amount it releases will not affect your bulbs in any way. Lawn food isn't the problem, not at any time of the year - what might be a problem is any combined lawn weed and feed preparations, (not autumn ones) which are usually applied in April. If you have bulbs in the turf, the advice is to wait until all bulb foliage has died down before applying. In other words, yes, you can use proprietary lawn treatments, just not when the bulbs are active, with either flowers or foliage. A wait of 6 to 8 weeks after flowering should be sufficient.
