Tip #1: Grow in the Coldest Room of Your Home
If you plan to grow Marsh seedbox indoors, make sure to choose the coldest room of your home. This will usually be on the side of your house that doesn’t experience the harsh heat that the sun can produce in the middle of the day. At the same time, you’ll need to ensure the room does get a healthy amount of sunlight. While you’ll want to spare your plants from the brightest and hottest part of the day, zero sunlight can drastically reduce Marsh seedbox ability to grow.
Tip #2: If Marsh seedbox Doesn’t Flower Properly, It May Be Too Hot
The growing season for Marsh seedbox, spring and early summer, can occasionally come with high temperatures. These fluctuations can negatively affect the growing stage of Marsh seedbox, causing flowering buds to change into non-flowering buds. These buds will open partially, or in some cases not at all, causing Marsh seedbox to lose some of its aesthetic quality. It's important to stay in the range of 65~75℉(18~25℃), for that reason, so your Marsh seedbox can flower to its full potential.
Tip #3: Avoid Frost
While Marsh seedbox can tolerate lower temperatures, as low as -5℉(-20℃), it will not do well if it encounters significant frost. If left out in the colder temperatures of late fall or winter, Marsh seedbox will begin to show the signs of frost damage. To recognize the signs of frost damage, you’ll look for several key aesthetic changes. First, parts of Marsh seedbox will begin to wilt. Then, those sections will start to become discolored, eventually turning brown or black as they die. Any parts of Marsh seedbox that turn these colors cannot be saved, and will have to be pruned if you intend to keep the plant alive.
