January Monthly Tips

The Flower Garden

  • Fill gaps in the garden with instant potted colour – Zinnias, Dahlias, Marigolds, Salvias, and Petunias will all flower on for some time yet.
  • Zinnias are great for providing summer colour. They also attract butterflies, bees, and birds to your garden.
  • Plant Gazanias and Arctotis in drier, sunny spots of the garden for masses of bright colour during the hotter months.
  • Keep dead heading flowering plants including roses – this will encourage more flowers to develop.
  • When picking roses cut a reasonably long stem, making your cut just above an outward facing bud.
  • Feed roses now with Rose food – this will encourage more flowers and growth to harden before the first frosts.
  • It is now time to plant the first of the spring flowering bulbs – Anemone and Ranunculus. More on Spring Bulbs
  • In warmer climates Hibiscus will be in full show. These respond well to plants food high in potash, such as citrus fertiliser. Remember to water well after feeding.

The Edible Garden

  • Regularly harvest quick producing crops this month. Courgettes, cucumbers, gherkins, beans, peas all need checking and picking on a daily basis. This will keep your veges young and sweet and stop them getting too big! It will also encourage plants to keep on producing for many more weeks.
  • Control white butterfly caterpillars with Derris Dust.
  • Continually plant crops of quick growing summer veges such as lettuce, beetroot, radishes, silver beet, bok choy. Now is also a good time to plant seedlings of the first of the autumn/winter veges – cabbage, cauliflower, leeks, spinach. Whanganui vegetable planting plan.
  • Keep feeding the summer garden. Liquid feed around tomatoes and peppers with liquid tomato food or iCan Fast Food liquid plant food. Give leafy veges like lettuce, silverbeet, a side dressing of ‘Sulphate of Ammonia’ to kick them along.
  • Continue to water regularly, especially if the summer is dry. Remember a good deep watering around the roots of the plants 2-3 times per week is more beneficial than a daily light sprinkling.
  • Adding compost and other organic material to the soil helps retain moisture as well as conditioning the soil.
  • Check fruit trees for brown rot and blackspot and spray with ‘Fungus Fighter’ if these are prevalent. More on sprays. or More on Organice sprays
  • Tomatoes will be ripening now. Thin out foliage around lower parts of the plants to allow light in and air around the fruit. This will speed up ripening and help keep diseases at bay. More on tomatoes. or More on tomato psyllid.
  • Garlic and onions can be lifted now and laid out to dry. More on Garlic and Shallots.
  • Harvest new potatoes as flowering finishes. More on potatoes.
  • Collect herbs for drying or making pesto and freezing.
