Before you purchase bees, you must first purchase a hive for them to live in. There are two types of hives, the rope hive & the wood hive. The difference between the two hives is their processing time to make honey:
Rope Hive - 23 gems & processes nectar into honey every 10 minutes
Wood Hive - 18 gems & processes nectar into honey every 20 minutes
There are two types of bees, the fat bee & the [skinny] bee. The difference between the two bees is that the fat bee works harder, bringing back more nectar faster than the skinny bee. Fat bees are better to have than skinny bees.
[skinny] Bee - 100,000 coins
Fat Bee - 150,000 coins
If you have more than one farm, the bees will visit both without you having to do anything. As you farm, you will notice them flying about, collecting nectar if it is available.
The bees will only collect nectar from specific trees & plants:
TREES: Apple, Apricot, Cherry, Orange, Pear, Plum, Sakura
GRAIN: Buckwheat, Sunflowers
FLOWERS: Camomile, clover, Lavender, Red Roses, Pink Roses, White Roses
To collect the nectar...
First, make sure you have trees, grain or flowers with flowers for the bees to visit.
1. You cannot collect nectar from fruit. Bees collect from flowers only.
2. You cannot collect nectar from flower buds. Flowers must be in full bloom.
Next, click on your hive & send the bees out. Your friends can visit your farm and release your bees, too. The more the bees get out, the more honey you will collect!
Last, after the bees have been out for a little while, check your hive to see if the bees are collecting & depositing honey inside. You can do this by hovering the tool over the hive just like you would for any other factory to see what is in process.
If your bees have not dropped off nectar & they have been out for several minutes, then click your hive & send the bees home. After you've sent them home, check the hive again to see if there is nectar in process. If there is, then you can send your bees out again to collect more if you want to.
You can send your harvester around while the bees are collecting & the bees will simply move when the harvester comes upon a plant they are harvesting nectar from. They won't be run over.
Depending on which hive you chose, the rope or the wood, will depend on how long it takes you to start collecting honey jars outside of your hive. Rope hives will produce a honey jar every 10 minutes & a wood hive will produce a honey jar every 20 minutes.
