May in the Garden

Life-is-a-garden-may

Hang in there gardeners! Your beloved, outdoor sanctuaries will soon be open.  While you wait for your post-pandemic indulgence at favourite GCA Garden Centre, let’s take this time to rejoice in this beautiful and envied continent of ours. May is Africa month with  African Day on the 25th of May. We will also celebrate World Bee Day on 20th May, and then the International Day for Biodiversity on May 22nd. Moms are also in the spotlight this month for Mother’s day on Sunday 10th May, and Life is a Garden highly recommends you spoil her with a little green treat.

With so many festivities, let’s revel in our African sunshine and plant some of our spectacular indigenous seeds and bulbs this season!

Ideas for Mother’s Day gifts from the garden

For kids of all ages: Moms love flowers, especially the hand-picked kind. If you have any of the following good cut-flowers blooming in your garden, they would be perfect as your Mother’s Day gift bouquet:

Tall flowering Dianthus, Carnations, Snapdragons, Larkspur, Alstroemeria or Sunflowers. If you don’t have these in the garden, you could always buy a few plants from your local GCA Garden Centre. The plants and their flowers will last for a long time - even till next year and then they’ll be ready for picking again.

Hot Tip: Pittosporum branches, leather leaf ferns, Aspidistra leaves and a variety of other plants, like those in Autumn berry, such as. the Pyracantha, can be added to your bunch of flowers too.

For the big kids and dads: Our indigenous wild banana plants (Strelitzia nicolai) are trendy additions to the new leafy-look, ideal in high light areas indoors, or as pretty patio plants. This plant is a stunner and even more so when planted in a lovely pot. Make sure mom stays modern and get her some wild bananas.

Hot tip: There are many beautiful orchids, cyclamen and other stunning plants available at your local GCA Garden Centre, just waiting to delight Mom this Mother’s Day.

Edibles

What would sausage and mash be without peas? Peas are also one of the few veggies that kids enjoy eating, especially when combined with corn. If you love peas, you will love fresh, home-grown peas even more. They are just so easy to grow from seed or seedling. Offer the climbing peas a variety of support to climb up, plant with a little compost, feed regularly, and hey presto, there you have your own home-grown peas.

Hot Tip: Peas are loaded with antioxidants and anti-inflammatory nutrients, including vitamin C and vitamin E, and more.

 

What to Sow

Some of the best seeds that can still be sown are indigenous beauties, which honour our African heritage with a parade of colourful flowers. These are:

Gazanias, Livingstone daisies (Mesembryanthemum), Scabious africana (the indigenous cape scabious or pincushion), and Namaqualand daisies (also called African daisies).

May is also a good time to sow Calendulas. Their perky orange and yellow flowers are great in plant borders and their edible flowers also make them a winner in the herb and veggie garden.

The month of May is an ideal time to sow shade grass and cool season seeds. They can provide the following solutions and more:

  • Shade grass can be sown into your existing lawn during winter. This is called over-seeding, which helps your lawn look green and healthy in the winter. Sowing shade grass can also be used to fill patches in an existing lawn.
  • Several different shade lawns can be sown. These are often available as both coarse and fine leaf lawns, and some can even withstand tough wear, such as areas where dogs like to run. .
  • Evergreen lawn seed is available for planting as a new lawn too.
Plant African bulbs in Africa month

There are beautiful indigenous bulbs that rival the Ranunculus, Daffodils and Hyacinths, [M1] especially once you take the time to get to know them:

Sparaxis or harlequin flowers prefer well-drained, composted soil in the sun or partial shade. Striking flowers that are often marked with a contrasting colour in their centre are good cut-flowers. These plants do well in the garden but are also excellent container plants.

Tritonia, also called blazing stars, offer a lovely range of spring-flowering colours - from bright orange to salmon, cream and white, and are also great cut-flowers. Make sure that you plant them in very well-drained soil, positioned in the sun or in semi-shade.

Lachenalias have cheeky and brightly colourful hyacinth-like flowers. Most hybrids have sweetly scented flowers that start flowering in winter. Good drainage is essential, so add some sand to poorly drained soil to increase the drainage. Their flowers are also great in vases.

Hot Tip: Don’t complete your bulb shopping before you’ve purchased bulb food. Before you go, take peek at the following other indigenous bulbs that are really something special and worth looking at:

  • Babiana, or baboon flowers, are the cutest little plants with attractive hairy leaves and fragrant flowers.
  • Freesias, which are fragrant and colourful, are great in containers and are very pretty cut-flowers.
  • Ornithogalum, or chincherinchees, have attractive white or green-white fragrant flowers, which are exceedingly long-lasting cut-flowers.

Ixia’s star-shaped flowers produce a riot of colour in spring, flourishing in a sunny or semi-shaded bed or container, especially when mass planted

It’s time to plant in the cool season with the 4 P’s. P is for princess and poppies, pansies, petunias and primulas - the royalty of our winter and spring annuals, which are now available as seedlings at your local GCA Garden Centre:

  • Iceland poppies are just gorgeous and available in mostly mixed packs of pastel or brighter colours. They are easy to grow, good cut-flowers, and overall just WOW!
  • Pansies and their smaller cousins, violas (which have edible flowers), are world-wide favourites and available in striking colours and vivid combinations.
  • Petunias are available in an array of colours too. These mound-forming annuals can appear cascading, while others are bushy. We recommend watering according to the natural winter rainfall in that area. Be careful not to overwater petunias.
  • Primula malacoides, or fairy primulas, put on a superb show and are shade-loving favourites for the cool season.

 

Bedding besties

Hot Tip: Regularly remove spent blooms from winter annuals, especially Iceland poppies, pansies and violas, to encourage more flowers.

Hot Tip: Tie sweet peas to their supports and remove tendrils or side shoots to encourage the nutrients in the plant to be used on necessary growth, and later, flowering.

Pick/Prune

Clean up perennials by removing any brown or dead leaves. Remove flower stalks from the summer and autumn flowering ones. Mulch them up with a little compost and water regularly.

The following Summer flowering bulbs require a little TLC at this time of year:

  • Once withered, cut back the foliage of Canna hybrids to the ground. Cover them with coarse mulch or compost and water regularly.
  • Once the leaves on your Liliums have died back, cut them off and cover them with mulch or compost and water regularly.
  • If you are not lifting Dahlias, cut the withered leaves down to about 15cm above the ground.
What to Feed

Do you eat in winter? We sure hope so! And we hope that you remember your winter and spring-flowering bulbs and annuals need food too! After all, they’re growing furiously at this time of year and need a little extra nourishment. Use a fertilizer that is rich in potassium since this will not only promote flowering or fruiting, but also make the plants healthier and stronger against the cold, pests, and diseases. A selection of liquid and granular/pelleted fertilizers are available to choose from at your local GCA Garden Centre.

TIP: The annual stocks and larkspurs benefit from extra nitrogen for growing and flowering through winter. Ask your local GCA Garden Centre for advice on a liquid fertilizer that will do the trick over the next month or two.

Blooming African star

Have you planted water-loving starlet (Spiloxene aquatica) in your water-feature? If you have, you would notice that from May, this indigenous “star” is peppered with little white, twinkly star-like flowers with bright yellow centres. Its spiky dark green, needle-shaped leaves grow up to 30cm long, making it a dazzling plant for a sunny spot in the pond, or water-feature.

Tip: If you have limited outdoor space, any waterproof pot can be turned into an exciting water feature for the patio, balcony or garden.

Rose care

Rose blooms may be picked with long stems. If the plants are in full leaf, continue to adhere to a spraying programme where watering may be reduced. It is a good time to plant winter flowering annuals like pansies, poppies, or compact snapdragons, on the edges of rose beds.

Lift and divide

Hot Tip: If the following perennials have stopped flowering, now is a good time to split or divide them.

  • The obedience plant (Physostegia virginiana). It has eye-catching bright-lilac flowers, is easy to grow and has a resilient nature and ability to spread freely. These flowers are truly beautiful, long-lasting cut-flowers.
  • Japanese Anemones (Anemone japonica) have large, interesting leaves and gorgeous blooms.

Michaelmas daisies (Symphyotrichum novi-belgii formerly known as Aster novi-belgii, have fine foliage and tiny daisy flowers borne on long stems. They are great cut-flowers and available in a range of purples, pinks, and white.

Inland gardening

In frosty areas, it is best to water between 10 am and before 2 pm. If you keep the roots of roses and many other plants moist, they are able to withstand light frost much better than dry plants.

Jack Frost will soon surprise you in frosty regions, especially the very cold Free State areas, closely followed by the Highveld, so start protecting your susceptible plants with frost cover. Frost cover allows the light in, while protecting the plants at the same time. Ask for it at your local GCA Garden Centre.

Hot Tip: To add gorgeous Autumn colours to a medium or large garden, consider planting a Liquidamber (Liquidamber styraciflua), or some of the smaller Maples in modest gardens.

Coastal gardening

If you’re in the Cape, make the most of your abundant winter rainfall by harvesting water from the roof. Check and clean your gutters, which may be clogged up with leaves.

Hot Tip: In coastal and lowveld areas, feed granadillas with a nitrogen and potassium combination fertilizer. You can ask for advice at your local GCA Garden Centre.
