Try not to take the same way in each time or you’ll have a trail to your plants. If there’s any water near by(but not right beside), carry a fishing rod. It can be a bit of a pain but it can also assure prying eyes. Know what fish are in there in case someone asks (who may know and is being nosy). I’d make a small barrier of sticks, just 3, around small plants to prevent deer from stomping them. Remove once they’re a metre tall. I’d make dust from garden sulphur/corn starch/talc and dust small plants to keep bugs and especially deer away. If it’s a swampy area watch for slugs, they can wipe you out when plants are small. hand pick them off if you have to. If you need GPS to find your spot (the harder to find the better) make sure you have many false waypoints in the area just in case. Carry “work clothes” in a backpack, and gloves. Pretty obvious if you come out wearing camo with dirty hands and a shovel.
And you can carry a lot of plants if you take them out of their pots and shake the excess soil off them. Stack them in a bag beside each other. Stack those bags beside each other. You can literally carry over 100 plants if you’re careful and only mess up a couple this way.
Or so I’ve heard.
