Sure, indoor gardening may be in your house, but many of the habits that keep outdoor landscapes healthy may be surprisingly useful indoors, too. Landscape maintenance relies on observation, consistency, planning and responding to small problems before they become big problems. The same principles can make houseplant care easier and more predictable.
Outdoor gardeners are constantly thinking of light, air flow, spacing, soil conditions, seasonal changes, and plant growth. Indoor gardeners have many of the same factors to deal with but the environment is smaller, and easier to control. Consider houseplant care in terms of landscape maintenance, and you can create better routines, and avoid some of the problems that occur when plants are left unattended too long.
The point isn't to turn your living room into a backyard. It is, instead, to steal the most useful maintenance habits from outdoor gardening and adapt them to the peculiarities of your home.
The first thing to understand in landscape maintenance is that plants don’t exist outside their environment. A tree, shrub or flower bed is affected by how much sun, what kind of soil, how well it drains, wind, the seasons and nearby plants.
Houseplants respond to the environment just like humans do. A plant next to a bright window is in different circumstances than one across the room. Heating vents, air conditioners, open windows, furniture and nearby plants can all affect the environment around a pot.
Instead of just looking at one plant, take a step back and look at the space around it.
Is the plant getting consistent light? Can the air get around the leaves? Is the pot in a place that makes watering difficult? Are the plants next door competing for the same window space?
Such questions are the stuff of the landscape gardener's mind when he is trying to determine where to put the plants outdoors.
One of the most important lessons of landscape design is to think ahead to how plants will grow, not just how they look today.
You bring a small houseplant home and it might look great on a windowsill. Months later its leaves may stretch to the glass, shade another plant, or make the area hard to get to. A plant that looked well spaced at one time can become crowded later.
Outdoor landscapers always consider the mature size of a plant when they select and position plants. Indoor gardeners can use the same technique.
Think about how tall and wide that plant is going to get before you get it in. Consider how much room the foliage will take up and if the plant will need support or a bigger container later on.
This simple habit can reduce the amount of re-arranging you have to do later. It also gives plants more space to develop naturally rather than forcing them into spaces that become too small as they grow.
Crowding is a frequent problem in the garden, whether it’s indoors or out.
A collection of houseplants bunched together looks beautiful, but dense foliage can decrease airflow and make it difficult to inspect individual plants. Leaves may remain wet longer after watering, and pests may be more difficult to see when plants are crowded together.
Outdoor landscape maintenance is a useful reminder that plants need room to grow and relate to their environment.
But that doesn't mean you need several feet of empty space around every houseplant. Leave enough room to access the foliage, to water the soil, to inspect the leaves and to move the plant when necessary.
Good spacing makes routine care more comfortable too. When you can see and reach your plants easily, it’s easier to notice changes before they become big problems.
Outside, gardeners rarely view sunlight as a fixed resource. The position of the sun varies during the day and during the seasons, and different parts of a landscape are affected.
Indoor gardeners can develop the same habit of observation.
A window that looks bright in the morning may receive far less direct light later in the day. Seasons can also affect how much sunlight enters a room, and at what angle. Furniture, curtains, surrounding buildings and even new growth on outdoor trees can change the light that reaches a plant.
Instead of judging a space only on how it looks at a given moment in time, take time to watch your expanding spaces.
See where the direct sunlight hits in the morning, afternoon and eve... Also, pay attention to seasonal differences This can be useful in selecting the better locations for plants with various light requirements.
The University of Minnesota Extension also offers helpful information on lighting indoor plants so you can learn how different houseplants react to the light available to them.
A healthy landscape isn’t healthy because someone comes in and does a big maintenance session every couple months. Small problems turn into big problems and regular attention is how you keep this from happening.
The same principle applies indoors.
Don’t wait until your plants look neglected. Develop a simple routine. While watering, check leaves, remove damaged foliage, clean dusty leaves when needed, check the soil and check under leaves for signs of pests.
The tasks do not need to take a long time. Consistency is the key.
A cursory five minute check every week can catch a yellowing leaf, some strange spots, dry soil or an insect problem much sooner than the occasional deep inspection. Early observation gives you more time to figure out what is going on and adjust your care routine.
Outdoor gardeners get to know what their plants normally look like. This makes it easier to see when something has changed.
The same skill comes in handy with indoor plants.
A sudden yellowing of a leaf, unusually stretched growth, or a plant that begins to lean toward a window can tell you something about changing conditions. One symptom may not be a pointer to one cause, but it is an indication for investigation.
Make an effort to observe your plants often enough to have an idea of what is normal.
You may notice slight changes in leaf color, growth pattern, soil moisture or overall form. This is about responding to what your plants are actually showing you rather than following a rigid schedule.
Gardening is simpler when gardeners have access to the plants they need to prune, inspect, water or otherwise care for.
The same rule applies to indoor gardening.
It’s tempting to place plants in every pretty corner of a room. But a plant hidden behind furniture or drowned by several larger pots can be difficult to care for. If watering involves moving several things first, care may eventually become inconsistent.
Consider access when you plan your indoor garden.
Leave enough space to get to containers, inspect leaves, remove dead growth and clean the surrounding area. Plants that are easy to reach are usually easier to take care of consistently.
The accessibility also makes it easy to rotate containers if needed, move plants if their conditions change, or isolate a plant that looks like it has a pest problem.
Another principle of maintenance that crosses over from indoor to outdoor gardening is cleanliness.
Outdoor landscapes accumulate fallen leaves, dead plant material, weeds and other debris. Inside the house the problems are different but the basic principle still has value. Leaves will collect dust, and plant shelves will collect dust, and dropped leaves and spilled potting soil will collect around the containers.
Routine care is easier when the area around your plants is kept reasonably clean.
Also, planting clean leaves helps plants to better use the light they have. Dusting foliage, where appropriate for the species, can be part of a regular care routine.
Don’t assume that cleanliness can replace proper watering, lighting or pest management. Instead, think of it like a minor part of keeping a healthy grow environment.
Maintaining gardening tools and equipment is important whether you grow plants indoors or manage a larger outdoor garden. Indoor gardeners may regularly use pruning shears, scissors, watering cans, spray bottles, plant supports, and other supplies, while those who care for larger outdoor spaces may also rely on lawn mowers and other powered equipment. Keeping these tools clean, functional, and properly maintained makes routine plant care easier and helps prevent small maintenance issues from interrupting your gardening routine. Resources such as UDC Parts can be useful when gardeners need replacement mower parts to keep their outdoor equipment ready for regular landscape maintenance. The same basic principle applies indoors: taking care of the tools you use to care for your plants helps make gardening more consistent and manageable.
Outdoor landscapes vary greatly across seasons, prompting gardeners to modify their maintenance routines accordingly.
And even within the shelter of walls, indoor gardens have their seasons and their changes.
Day length varies over the course of the year. Heating and cooling systems can change the indoor temperature. The humidity can also change with the seasons and the way a house is heated and ventilated.
A plant that gets plenty of sun in the summer may need a different location in the winter. Other factors that can influence how often to water are temperature, humidity and light levels.
Notice how your indoor environment changes and adjust accordingly rather than doing the same thing all year long.
One of the best things outdoor gardening can teach indoor plant lovers is seasonal awareness.
The biggest lesson outdoor landscape maintenance has to offer indoor gardeners isn’t some particular tool or technique. It’s a way of thinking.
Healthy gardens result from observation, planning, consistency and timely adjustments. Plants require sufficient space, light, ventilation, and regular care. Small changes are easier to take if they are caught early.
You don’t have to turn your home into a mini landscape to put these principles into practice.
Plan for plants to grow. Look for changing light conditions. Allow room for airflow and to check the foliage. Keep your growing area clean and open. Care should be adjusted with seasonal and indoor changes. Keep the gardening tools and equipment that make the gardening possible.
Whether you have two plants on a windowsill or a house full of greenery, these habits can help make indoor gardening fun and more organized.
The basic lesson is surprisingly similar whether you're working with a huge outdoor landscape or a small indoor garden: healthy plants require good planning, close monitoring, and routine maintenance.
