What a Plant Wants

After you’ve thought about what you want, consider what you can provide the plants given your environment, space and time commitment. Of course, plants need light, food, air and water, but the quality and quantity varies from plant to plant. (Read more about plant requirements here.)

Read seed packets, plant descriptions or online references and then grow plants with similar requirements together.

Find out how big your plants will be when mature and make sure your container can accommodate that. Dwarf varieties usually do well in containers since they are small by nature.

Potting Mix
Container plants do best in a potting mix rather than in garden soil which can compact easily. Often garden soil contains weed seeds, pests and other critters you don’t want in your containers.

Look for a mix that is light, fluffy, drains well and contains enough organic material to hold water and nutrients. You can purchase a pre-mixed potting soil or make your own.

When purchasing potting soil (not really soil at all) read the package carefully. Instead of buying something labeled “topsoil” or “compost” which could be made of just about anything, invest in high quality organic potting soil.

If you choose to make your own, find a good recipe and experiment. A classic soil-based mix is:

1 part peat moss or mature compost
1 part garden loam or topsoil
1 part clean builder’s sand or perlite
Watering plants in containers is different than watering plants directly in the soil. Potting soil is often less dense than garden soil and thus holds less water. Additionally, the pot restricts the amount of soil to hold water. And because the pots are above ground, they don’t have all that mass around them to keep cool.

Too much or too little water will kill your plants. The idea is to keep the soil moist throughout, but not wet. Many container-grown plants need to be watered once or twice a day when it is hot.

Plant Waterer
Bordy Plant Waterer
Going on vacation? The Scheurich Bordy will watch after your plants for 4 days.

Going on vacation? The Scheurich® Bordy is an attractive and effective automatic plant waterer. Not only a handy plant companion but this cheery little bird makes its mark as cute home decor. Simply fill with water and rest assured that your plant will be perfectly watered for up to four days.

Use a watering can or garden hose to wet the soil directly (not just the leaves!). If you still can’t tell how much water is needed, consider a digital moisture meter for an exact reading.

If you plan to be away from home for several days a drip irrigation system can keep your plants happy. Purchase one or make your own (Learn how to make your own pop bottle irrigation system here).

You can also retain water longer by adding “agro-polymers” (sold under the name Soil Moist) to the soil or potting mix before you plant.

Adding organic mulch to the top of your containers will retain moisture on warm days and add nutrients to the soil (remember that nutrients leach out each time you water and need to be replaced.)

Most plants need 7-12 hours of sunlight a day (especially herbs and vegetables with fruits). If you don’t have that, look for shade tolerating varieties like spinach and chard.

Read seed packets to determine the amount of light an individual species needs. Here’s what the packet terms mean:

Full Sun: Between 6 and 8 hours of direct sunlight per day.

Partial Sun: Plants require between 4 and 6 hours of sunlight a day, preferably in the morning and early afternoon.

Shade: Less than 4 hours of direct sunlight per day, with filtered sunlight during the rest of the day.

When you move your containers indoors for the winter, you may need to give them an extra sunlight-boost with plant grow lights. These specially designed lights simulate the sun and help plants thrive through the dark of winter.
