Sow Red Salad Seeds

Sow Red Salad Seeds

Red food stuff is a popular trend at the moment. Good leafy crops add vibrancy to a salad and you are probably eating well if you grow them yourself.

Book Cover

Seeds of fast leafy salad crops can be sown until the end of July and they will be ready to start picking in about 50 days. Loose leaf Lollo Biondi and Lollo Rossa will be ready from about this time and you can pick individual leaves as you need them. Give them some cloche protection in September and you may be picking through October.

Salad seedlings are nutritious and at the peak of flavour so try Red Mustard or Red Chard for early picking but with added colour for your salads. The spring onion North Holland Blood Red is also worth eating as you thin our the crop.

For something with a bit more kick Rocket, Radiches or Nasturtium leaves may suit or try Mizuna or the leaves of Beetroot.

 

Supporting Role of Stakes, Ties and Canes

Supporting Role of Stakes, Ties and Canes

Lush growth in May and June will create abundant growth and plenty of colour. But by mid summer and early autumn a shabbiness of middle age may have crept into your borders. However a border that has been carefully staked and tied in spring and summer will not lapse into slovenly habits.

Tips for Using Canes

  • It makes sense to support single-stem plants like Hollyhocks, Delphiniums and Gladioli early in the season but it is never too late. When tying stems to a cane make a loose figure-of-eight with the twine or a tight knot will damage the the stem.
  • You can make your own ‘pea sticks’ from Hazel, Elm suckers, Beech or even Fir.
  • If you want to grow your own canes then the bamboo Phyllostachys nigra produces unobtrusive black canes.
  • Use thick canes if possible – buy 8 foot canes and cut in two with a fine hacksaw at a joint
  • Freshly bought canes can be cut with secateurs
  • Single canes are not appropriate for multi stemmed plants as the string just makes a noose for the plant to flop into. Put two canes at the back and at least one in the middle then a web of string can provide several supports.
  • If your string slips down the cane your effort will be wasted. use a clove hitch knot slid down from the top of the cane and keep the know just above a joint.

Off the Peg Plant Supports

  • Circular wire grids too set above a plant for it to grow through are available but are not cheap. The green plastic covering on the wire isn’t totally natural in appearance.
  • Interlocking stakes with a hook to link to the next stake helps make a support shape appropriate to the plant can work quite well. I use these for Peonies.
  • Semi circular hoops for the border edges are available to hold plants back from lawnmowers
  • Part off the peg and part DIY you can use a wire grid supported in 4 corners to cover a wide area of the herbaceous border.
  • Obelisks and a variety of cast iron towers are available for training climbing plants

Common Lawn Weeds and Treatment

Common Lawn Weeds and Treatment

Book Cover
Bellis or Daisy is recognised by it’s flat rosettes of oval leaves and small white yellow eyed flowers. They tend to form colonies that hug the ground to smother out nearby grass. From the boots of the ‘My old mans a dustman’ song, ‘it takes such a job to pull them up that he calls them daisy roots’ the best treatment is a selective weed killer that may need a couple of applications. Alternatively each root can be dug out by hand.

Dandelion leaves are recognised by long hairless coarsely toothed leaves that form large rosettes. They form dense mat to suppress the nearby plants or grass. The flowers are bright yellow and self-seed freely from Dandelion clocks the globular seed heads we blew as children. The long tap root will regrow unless removed completely or killed by systemic weed killer. Spot treat the weed with a touchweeder or selectively apply a weed killer. Burning and boiling water on the leaves may have some impact on crazy paving but i don’t find it works on lawns.

Buttercups stunt nearby plants and make the lawn look uncared for. remove by hand or normal weed killers.

Clover has shamrock shaped leaves (not real rocks as you find in rockeries). Clover stays green in drought and as a leguminous plant its roots provide nitrogen for grass but the pink or white flowers are intrusive. As clover thrives on poor soil feed the lawn and use a grass box on the mower to remove seed heads. Lawn sand may be used to treat the problem.

Plantains have large leaf rosettes that can smother grass and compete for vital nutrients. Fork out by hand or treat individually.

Annual meadow grass hosts harmful eelworms and is hard to control with weed killers. The leaves are short tufts and strap shaped with tiny coarse flowers. in summer they can die back leaving patches. Feed the lawn well and use the grass bow when mowing. really bad investations may need re sowing or turfing.

Moss is a dense low growing mat of greenery that affects badly drained lawns. It is too short to be cut by a mower but a lawn that itself is cut too short can attract moss instead of grass. Feed the lawn with a weed and feed fertiliser or use lawn sand containing a moss killer. Scarify and improve drainage by forking over the lawn

Saxifraga Fortunei Cherry Pie

Saxifraga Fortunei Cherry Pie

Saxifrage Fortunei Cherry Pie

Saxifraga Fortunei ‘Cherry Pie’ looks good from late August through Autumn with these cherry coloured flowers. It is recommended as a good plant for moist woodland as it is happy with partial shade. Grows 8-10″ tall with flowering spikes above bright palmate, green leaves.

The Saxifrage society modestly claims to be ‘the only international organization dedicated to the best plants in the world; the genus Saxifraga or Rockfoils and its relatives.’ They have 480 species to go at in three groups or sections the “mossies” (Saxifraga), the “silvers” ( Ligulatae) and the Kabschia and Engleria subsections ( Porphyrion).

Book Cover

I am just getting interested in growing some of these plants and I will see how I get on. The Saxifrage Society is to be represented with a display stand at the RHS Harlow Carr Alpine weekend 15-17 April 2016.

For some it becomes a consuming passion or so I am told. Many saxifrages come from mountain habitats that make them well-suited to rock gardens, troughs, and containers.

The increasing interest in Alpines and rock-gardening has resulted in the introduction of countless new varieties

Plant Autumn Crocus

Plant Autumn Crocus

I have just bought and planted some Autumn ‘Crocus Speciosus’ AGM that were part of a birthday present. I could have waited until summer to plant the bulbs. Flowering bright blue are about 4 inches tall. I hope to see the blue veined flowers with  deep yellow stamen  by October  followed by leaves in spring. The thin flowering stems find it difficult to withstand wet and windy weather and are inclined to flop but I have given them some shelter in the rockery.

Autumn crocus are not cheap but they can last for years given favorable conditions. Autumn crocus or meadow saffron is a poisonous member of the lily family.

Autumn Crocus Tips

  • Plant about 4 inches deep and be prepared for them to flower a bit later the first year.
  • Try other varieties of Autumn flowering crocus of which there are many including the saffron Crocus sativus, Crocus goulimyi, Crocus pulchellus, Crocus agrippinum and Crocus nudiflorus, Crocus clusii, Crocus laevigatus Fontenayi, Crocus pulchellus and Crocus Zephyr
  • Excellent for naturalising in wild gardens, rockeries and between shrubs according to my packet instructions (but they are unlikely to say good chance of failure).
  • Many colchiums and autumn crocus they can flower without soil indoors prior to planting out.
  • Increase your stock via freshly ripe seed or dig up the corms when the leaves fade in spring pulling them apart and replant the cormletts.
  • Mice can be troublesome because they eat the Crocus corms so protect them if you are troubled.

Spirea Shrubs

Spirea Shrubs

Spirea

I have two very good Spirea varieties where I have long since lost the names. This example is a strong flowering mauve and white flowering plain leaved type. The other is a pale yellow leaved variety that has great colour in spring as the leaves start.

How hard was it going to be to identify the plants surely it can’t be too hard. I went to my copy of Hilliers Manual of Trees and Shrubs only to find over 80 species, varieties and cultivars described.

Well the next lesson is that I haven’t even considered my Spirea’s habits and Hillier identified those that flower on this years wood and those that flower on previous years wood – how have they thrived on my random pruning regime?

My first shrub is 6 -8 feet wide and currently covered in blossom on the ends of this years growth. I am going to give it a hard prune almost to the ground in March working on the thesis that it is a bumalda- japonica- douglasii .

Red Hot Dahlias

Red Hot Dahlias

‘Fiery’ hardly does justice to this cactus Dahlia.

Often seen as the preserve of competition growers Dahlias are hot and sexy again. I have just restarted the tubers I lifted last Autumn. I use large tubs in a frost free area until the danger of frost has passed. I can take cuttings from new growth and will get flowers in summer and new tubers.

Many suppliers and thus varieties are available at stockists.  Sarah Raven the gardening commentator is keen to promote the flowers for their intense, hot colours that they can bring to the garden. She is not far wrong and I increase the number of Dahlias I grow each year.

What is AGM – Award of Garden Merit

What is AGM – Award of Garden Merit

This is the Royal Horticultural Society symbol for the Award of Garden Merit ‘AGM’. This award indicates that the plant is recommended by the RHS.

Awards are usually given after a period of trial at an RHS garden.

The AGM is intended to be of practical value to the home gardener. It is awarded therefore only to a plant that meets the tried and tested plant varieties using trial methods and  criteria.

AGM Criteria

  • It must be available in the UK
  • It be of outstanding excellence for ordinary garden decoration or use
  • It must be of good constitution – the award includes a hardiness standard – H4 is hardy through out the UK
  • It must not require highly specialist growing conditions or care
  • It must not be particularly susceptible to any pest or disease
  • It must not be subject to an unreasonable degree of reversion in its vegetative or floral characteristics.

Miniature Pelargonium

Miniature Pelargonium

Minature-pelargonium - Golden Chalice

Pelargonium ‘Golden Chalice’

This fancy Pelargonium was new to me. I bought the plant whilst on holiday at a specialist pelargonium nursery in Stokesley Yorkshire some years ago.

As you may be able to see the leaves are a maximum of half an inch wide. This earns it the sobriquet of a miniature bi-colour.

The blooms are pink speckled with red and there is plenty of bud. The flowering should continue virtually on checked through out winter growing it as a house plant. Since it takes up so little space, yet has a distinctive form, I may try to propagate from this stock plant and acquire other varieties to make a miniature collection.

The parent has been a profligate producer of off spring. Many plants have been given away as houseplants and some of my stock is planted in the border. Cuttings root easily and the miniature nature of the plant always attracts attention. I an going to group them together this year and see how they fare.

Pinch out growing tips to make the plant bush out and provide more flowers.
