When it comes to determining how far away plants should be from your house, there are a few things to consider. First, you'll want to think about the size of the plant. If the plant is small, then it can be placed closer to the house. If the plant is large, then it will need to be placed further away from the house. Second, you'll want to consider the type of plant. Some plants need more sun than others, so if you're placing a plant that needs full sun in an area that doesn't get much sun, it won't do well. The same goes for shade-loving plants - if they're placed in an area that gets full sun, they'll likely suffer. Third, you'll want to take into account the climate where you live. In some climates (like tropical climates), it's best to keep plants close to the house so they can receive protection from wind and rain. However, in other climates (like desert climates), it's best to keep plants further away from the house so they don't overheat. With all of this in mind, there's no hard and fast rule for how far away plants should be from your house - it really depends on the individual plant and your specific situation.
