Harvest your plants, when you harvest them-it may only be elder harvest but if memory serves mature harvesting as well-you will get Gardening XP and other random items. Enough Gardening XP and you level to next Gardening level.
On test it took about 12-20 harvests of plants the level you are at, with the variation due to much better XP from elder harvests.
I planted on Tues, and have kept planting since, and expect to hit level 2 tonight....
Yes but how to you harvest? I have been trying to interact with my boomshroom but have not figured it out. I have waved my wand over it, looked through my tools, and flew over it. I am not getting a prompt to hit x or anything else.
When the plant has sufficiently matured, after becoming mature but before elder status it will interact when you can harvest it by giving you the X option to harvest. In gardening mode if you put your mouse over the plant it will give you a count down telling you when you can harvest next.
i'm clueless in leveling up in gardening what do i do to level up?
Well, what I do is I go to the Bazaar, go to the housing section look for seeds that are my rank and then buy them go to my home and then two days later ( or 3 days ) it's time to harvest! Then I keep harvesting over the next few days and when their elder harvest them for the last time then buy more and go threw the same progress.
