Just a heads-up:

If you do any gardening within a few hours of leaving on a trip, make sure you take a shower immediately, and don't touch anything that you plan to pack. And definitely don't touch your suitcase unless you've washed thoroughly.

I recently fertilized my roses then left a few hours later for London. On the way back, my luggage set off the security wand thingy, and it caused a 45 minute delay to our plans as I had some 'splainin to do. Luckily we were there in plenty of time and it didn't impact our plans in any way.
