Garden fresh in a pot

Steve and Louisa Portman share some of the secrets to happy, flourishing container plants.

Pots, tubs and hanging baskets full of flowers or greenery not only brighten up a deck or patio, they are practical too. You can move potted plants if you want to change the focal point in the garden, or if you want to get them out of wind or into sunshine.

The secret to a pot full of healthy plants is starting with quality potting mix. We always recommend buying the best you can. In the long run it will save you money as your plants will not need as much feeding or frequent repotting. Good potting mix also holds moisture well so you may not need to water so often.

The container is also important – it’s easier to grow plants in larger containers as they are less likely to dry out. Plants in too small a pot are in danger of becoming root-bound, particularly if they are intended to grow in the pot for more than a season. And whatever material the container is made of it should have adequate drainage holes.

PLANT CARE

Water both the potting mix and the pot plant thoroughly before planting. Once planted, how often you need to water will depend on the season, size of plant and pot. Keep an eye on moisture levels particularly in summer when you can expect to water thoroughly two to three times a week. Never let pots dry out completely. Using mulch on the top of the pot will help retain moisture.

Container plants are in a limited environment so feed them regularly with nutrients, such as a seaweed-based plant food. Be guided by the health of the plant, but once every two weeks should be adequate.

PICK YOUR PLANTS

You can choose almost any plant as long as they suit the climate, conditions and container. One type of plant per pot can be striking but it’s fun mixing it up with different plants. The rule of thumb is to choose a feature (or a ‘thriller’) plant, a creeper (‘spiller’) and a few ‘fillers’ of greenery to add texture.

TOP TIP FOR HOLIDAYMAKERS

Save yourself a trip to the shops if you are camping or staying at a bach this summer. Two or three weeks before you go, plant out a plastic trough with herbs and salad greens, and take it away with you. And we don’t think it’s too early to say it would be a thoughtful Christmas present or gift for hosts.
