‘Ready’ Primula Plants for Spring

It is mid July and I have just placed an order for some colourful spring Primulas.
Choosing from a good selection at   Jersey Plants Direct  I opted for Auriculas and Rosebud Primroses.  As an alternative I could have ordered  Polyanthus (primrose flowers on stems) or a wide range of self-coloured primroses.

What and Why Buy Now

  • Ordering now, the plants should be delivered in good time to be planted and settled whilst the soil is warm and getting damp.
  • I do not do well growing these plants from seeds (which is very expensive) so I find the investment in plants well worthwhile.
  • My supplier offers various sizes of seedlings from 160  plugs 4-8cm, ‘Ready’ plants 6-10 cm, jumbo 7-11cm and super jumbo 8-12 in 5.7cm wide modules. I opted for the ready size as growing on small plants in the past has caused me higher losses
  • The quantities mean I can split the delivery into two and plant half in a cold frame and half in their flowering position to see which section performs best.
  • As recommended by Jersey I will grow some Rosebuds in pots for the house.

Five Primrose Pictures

Primroses that bloom in the spring tra-la seemed a good title for these pictures with short pithy comments attached.

Primrose
Hedgerow primroses grow well in the shade but flower better when a bit of sun breaks through the woodland branches waiting for their new leaves.

Flowers that Bloom in the Spring, tra-la
The inspiration for these five pictures of Primrose in their many colours.

Primroses in Spring

Leaves can die back shortly after flowering. The longer they are green the more they are feeding the roots and plant for future flowering.
Water and feed after flowering, you would be hungry and thirsty after producing so much seed and progeny.

Haworth primroses

Some colour look good and faithful on computer screens. I think that this applies to these Primroses.

Primrose
Bred as a double flower this Primrose has interesting colouring. Some plants can be over bred and are then hard to keep from one year to the next. This is the second year of this plant.

Primula Denticulata or Himalayan Primrose

Spring flowering Primulas are one of gardens wonders. The ‘denticulata’ flowers are held on firm high stalks up to 12″ above ground. The globular appearance is due to the mass of small florets that group together to form a ball shape.

Primula denticula alba

In early March this white Drumstick Primula Denticulata is full of flowers on stalks that are just breaking free from ground level.
Within a week the stalks will be over 10 inches tall and fully open.
Admired by the neighbors I often split the plants and give examples away.

Repotting Permanent Pot Plants

Hols spain 543

When a plants roots fill the pot then it is time to think about repotting. Compost breaks down overtime, becomes prone to waterlogging and is less aerated. Plants in John Innes No.3 compost will last a bit longer but repotting every couple of years may still be needed to retain vigour.

Why Repot

  • Repotting helps consistency of watering. You are less likely to get waterlogging or dry compacted roots that are hard to water.
  • New compost and nutrient is made available to your plants.
  • Cramped roots will stunt the plants ability to perform above ground.
  • Tip for bulbs like Eucomis- Pot up in black plastic pots, then place inside a decorative pot in summer.

How to Repot

    • Early spring is a good time to do your repotting.
    • Gently ease out the root ball whilst supporting the plant.
    • Tease out some compost (upto a third) from the top and bottom and free any roots that are growing round and round the pot edges.

 

  • Lightly trim the roots from around the edges. If they are very tightly packed slice off a good sliver from one side.
  • Select a slightly larger pot, place the plant in the centre at the same depth and fill in the sides with fresh compost. Push compost down to avoid air pockets.
  • Add some slow release fertiliser granules as you repot and push some into the old root ball.
  • In years when you do not repot, top dress the pot with fresh compost by scraping away the top 2″ and adding fresh compost.
  • An over-potted plant will focus on root growth at the expense of new foliage and flowers.
  • Water the repotted plant and if the compost sinks top up or add gravel as a top mulch

Repotting House Plants

  • The process is very similar to other repotting.
  • It may be obvious that a plant needs repotting when roots grow out of the hole in the bottom of the pot.
  • Water the plant before you take it out of its current pot and let it stand for a couple of hours.
  • Once repotted do not feed for 6-8 weeks as the compost should provide new nutrients.
  • Keep your tools and pots clean and sterile particularly for Orchids.
  • Use appropriate special purpose composts for Citrus trees, bonsai, African Violets, Orchids etc.

Indoor Primula Tips

primula-obconica

Indoor plants that are in full flower in January include the strongly coloured Primula Obconica shown above. They look good in traditional blues, pinks and white with the new Twilly series including a strong red. There are plenty of long lasting blooms particularly if you pick off dead flowers. The hairs on the back of leaves can be an irritant so take care if you have sensitive skin, the plant is also known as Poison Primrose.

Plants at garden centers may have been grown specifically for a quick show of colour that makes them saleable and decorative as indoor plants. They are probably not frost free or very hardy.
Primula 011

Primula Obconica

  • Unlike other Primula obconica varieties, Twilly Touch Me is primine free, so causes no skin irritation.
  • Grown from seed give them dark to germinate. They flower the following spring/summer in the cool greenhouse or as a houseplant.
  • Primula obconica produce a dozen different colours of flowers.
  • The flowers last for several weeks if spent flowers are deadheaded regularly.
  • Do not let the plants dry out and the leaves become floppy.

  • The Yew is associated with folklore and is often found in churchyards.

Yew - Taxus baccata

Gardeners Tips for the Yew

  • The yew can be clipped or pruned into topiary and makes a good hedge or wind break. As it is slow growing it is easy to keep it within bounds.
  • Old trees can have a girth of 20-30 feet.
  • Will grow on dry chalky soils and in the shade.
  • Taxus boccata ‘Erecta’ is a columnar form worth growing in your garden.

Other types of Yew

  • Taxus baccata ‘Fastigiata’ or the Irish Yew is one of over 100 cultivars and the several cultivars with yellow leaves are collectively known as “Golden Yew”.
  • Taxus brevifolia or the Pacific Yew is native to northwest America.

Yew comments from elsewhere

  • ‘The Yew is considered to be the most potent tree for protection against evil, a means of connecting to your ancestors, a bringer of dreams and otherworld journeys and a symbol of the old magic. In hot weather it gives off a resinous vapour which shamans inhaled to gain visions. Yew wood was regarded as especially magical to the Celts, due to its connection with the dead and the ancestors which were deeply respected. Archaeologists have recently found well-preserved Yew wood carvings at ancient sites of springs and wells which were probably votive offerings. ‘read the full story on White Dragon

Very Hardy Tough Plants

poppies

Some plants are so reliable, accommodating and long lived that they earn the sobriquet ‘Bomb Proof’. As soon as I say that there will be howls of complaint that all my bomb proof selection have failed in one garden – well all I can say is you should not need green fingers to grow this bomb proof selection.

Gardeners Tips for Bomb Proof Plants

  • Rosa Rugarosa or Dog Roses are found wild in hedgerows and that means they survive what ever the British weather throws at them.
  • Taxus or Yew trees grows quicker then expected and can be pruned, trimmed and shaped. Old specimens in church yards can be several hundred years old so your tree is likely to outlive you.
  • The Grass in my lawns has been through drought, flood and plagues of children. I chop it down with a mower at least 30 times a year and treat it badly. It may go brown, grow some moss or suffer from Fairy rings but the green grass keeps coming back. If that fails there is also the horrible Gardeners Garters the stripy grass that is worse than couch to pull out.
  • Cat mint or Nepta Six Hills Giant is a robust plant that grows to 18″ but it prefers full sun. It is extremely drought tolerant and will  grow in poor soils.
  • Some plants survive like weeds and in my garden Creeping Jenny Lysimachia fits into this category.
  • Poppies are almost bomb proof due to the volume and longevity of the seed they produce. Iceland poppies and opium poppies Paperver somniferum are a couple of cases in point.
  • Flowering onions or Alliums have hardy bulbs and once a plant is established they are adept at seeding and growing colonies.
