There's a few pros and cons to selling roses in the summer. There are more pros in actuality. While there aren't any flowery holidays that I can think of in the summer, that only serves to drive the price of wholesale roses down.
If you're out selling roses in night clubs on the weekends, so what if there's no rosey holiday--those are only good for a few nights a year anyway and people go out on dates all year. In the summer if you sell anywhere near a beach, in fact it will be your busiest season.
Now one thing is it gets hot. I always keep my roses in the back inside a big cooler with ice packs in it and some up front in my basket with the AC blowing on it.
This cooler is a very handy, dandy thing to have if you're gonna be a rose seller, because if you don't have room in the bottom of your fridge and you're not ready to invest in a second fridge(but you can pick one up for 75 bucks at a thrift store or garage sale) a nice big ice chest type cooler is also a great place to store your roses in the house, you'll just have to remember to switch out the ice packs. Now I've got a really good tip for you on the cooler. Normally a nice large cooler can be over $100, right now they have a real long cooler for $80 that is just perfect and what you'll eventually want to get. But if you're a newbie and are just trying this out that could be a big investment for you. So what is cool right now about coolers is that at WalMart I have seen they now have some very large as big as the large ice chest cooler I mentioned styrofoam coolers for only $20 and another one that's shorter than this one but still pretty big for just $8!! This is even good news for you experienced sellers as we often need something extra. Anyway I had never seen any styrofoam ones on sale that were that large so...
As I said wholesale rose prices are down as well. If you looked around online for wholesale roses during the spring and god forbid around Valentine's Day you'll see the big difference.
I'm excited because I got to actually make a new page on my wholesale site where you can probably get the best deal online as this even includes the shipping : http://roseladywholesale.com/bulkoffers.html
