Delosperma Succulents in Your Garden

Delosperma Succulents in Your Garden

Delosperma are plants to keep your eye on as there popularity increases.
Wild Delosperma are South African succulent perennials related to Mesembryanthemums. Some Delosperma may need some protection from wet in UK winters but the colourful daisy like flowers are attractive and bloom in masses over long summer periods.

Delospurnum Pink Ribbon

There are many forms of Delosperma with vast numbers of showy flowers produced over long periods. Some species form low, dense clumps and are more suitable as groundcover in shady spots.
The flowers are available in a series of bright colours to attract pollinating insects. The leaves are generally green, glossy and sometimes tinged with red.
You can grow Delosperma plants from seed or cuttings and buy examples from a growing number of nurseries.

Plants from T&M

British, French and Spanish Lavender

British, French and Spanish Lavender

I have taken a slight liberty calling English Lavender (Lavendula augustifolia) British, which it surely must be.
Other Lavenders will grow and thrive in the UK including French and Spanish Lavender but they will last only a few years whilst English Lavender can live for 20+ years.

Lavender

English Lavender (Lavendula augustifolia)

  • Varieties to look for include Imperial Gem, Hidcote and Munstead which have a compact habit and Melissa Lilac.
  • These British Lavender flowers in early summer on short flower spikes a few inches above narrow, grey-green leaves.
  • In August the flowers will be virtually over and the plant can be trimmed back hard so they regenerate before winter
  • Cut flowers for drying in late June and early July

You can acquire or just admire plants as part of a collection

Spanish Lavender

Growing Tips for Lavender

  • Water in the first season so the Lavender can develop deep roots then in future years they can survive on very little water.
  • The silvery aromatic leaves indicate that Lavender prefers full sun and good drainage like similar plants.
  • The tufted French and Spanish lavenders are variable in habit and flowering colour.
  • Buy plants from a good nursery who will have a stock of varieties.
  • Grow Lavender from cuttings from May to August

Growing Your Gerbera Outdoors

Growing Your Gerbera Outdoors

New varieties, aggressive marketing or clever breeding are encouraging UK gardeners to grow Gerberas outdoors. The two photographs below are of plants on sale at a local garden centre.
Beware these outdoor Gerberas do not produce flowers as big or robust as the charming florists varieties of Gerbera. Global warming may help but a sheltered sunny spot will have to do for the time being.

Gerbera outdoor

This is a nice red Gerbera but the flowers are only about an inch across. I think these plants are being marketed as Gerbera Garvinea or ‘Forever Daisies’. As regular readers will know I think any plant that needs ‘marketing’ is very suspect.

Gerbera outdoor
The golden coloured flower was bigger than its red cousin but still looked smaller than traditional Gerbera flowers. Traditionally these would be Gerbera jamesonii and Gerbera viridifolia or a cross between.

Photogenic Pelargonium

Photogenic Pelargonium

Photogenic Regals, Angels, Zonals, Scented leaved, Dwarfs, Miniatures, Alpine, Stellar, Ivy Leaved and Uniques are all types of Pelargonium. It is this variety that makes Pelargoniums photogenic and more importantly worth growing as a hobby for house, conservatory or garden.

Secrets of Success With Peonies

Secrets of Success With Peonies

Bold and brash blooms are a beautiful feature of Peonies but being successful is not a real big secret.
Peonies are easy to grow, herbaceous perennials that should be long lived if you follow these five simple tips.

Peonie

Five Secrets of Success With Peonies

  • 1. Peonies need deep, fertile, moisture retentive soil and summer rain or watering.
  • 2. Do not bury the crown too deeply when planting or in later years with over-enthusiastic mulching. 2 inches below the soils surface is adequate
  • 3. Cut down foliage to ground level in Autumn. Top dress with a handful of bone meal or growmore and then again in spring. An occasional top dressing of lime can be beneficial if the soil is prone to acidity.
  • 4. Deadhead plants after flowering to put energy into new growth. Be patient if new plants do not flower in the first year, so long as they are not planted too deep your peonies will eventually flower.
  • 5. Stake with a ring of metal hoops to support the heavy blooms. They get particularly heavy when wet.

Peony Hakugan

Tree Peonies like the one pictured above do not need to be cut down. I avoid pruning Tree Peonies and you can get more tips here.

Aphids and other pests are deterred by toxic chemicals in Peony leaves.

Plant in October or during frost free periods.

Aim to grow Peonia lactifolia whose flowers are longer lasting than Peony officinalis the cottage garden variety of Peony.

Secrets of Success Growing Marjoram

Secrets of Success Growing Marjoram

Get sweet success from the perennial herb Marjoram, the Oregano relative with the nectar that tops bees and butterflies gourmet guide. Marjoram flowers are rich in sugars and the nectar is a great attractor for insects.
We grow Marjoram for the leaves to use in cooking and the flowers can be dried and then used for flavouring during winter.

Small Tortoiseshell on Marjoram

Marjoram is hardy perennial herb that has sweet smelling, aromatic foliage which is commonly used in Mediterranean cuisine.
Sprinkle Marjoram or Oregano on lamb, pizzas or pork before cooking. Marjoram makes a useful and low maintenance addition to the herb garden growing 18inches high and wide.

Marjoram

Marjoram from Seed

  • Seeds at Thompson & Morgan
  • The best growing location for Marjoram are in a warm sunny spot.
  • Marjoram likes a dry, lime-rich, chalky soil.

Varieties of Marjoram

  • Marjoram is also known as Oregano in America. They are from the same family.
  • There are three main species including Wild marjoram that is often found on seaside cliffs.
  • Sweet marjoram (Oreganum majorana) tastes the best and is great for cooking.
  • Pot marjoram (Oreganum onites).

Windowsill Gardening

Windowsill Gardening

If you have a windowsill you can do all sorts of gardening. If you like flowering plants, herbs or just greenery to clean the air a vast range of plants can be successfully grown on your windowsill.

Windowsill Gardening – The Sun’s Effect

  • Beware the sun is stronger through glass. South facing windows can provide too much sun and burn the delicate leaves. If worried shade plants or move them back from too near the glass.
  • East and west facing windows can also have quite strong sun that will dry soil or compost quickly. Give windowsill plants regular watering and a weekly drink of a dilute feed whilst in strong growth.
  • North windowsills can be fine for plants that do not need direct sun including Orchids.
  • All plants grow towards the light, some more pronounced than others. You want plants to be even all around not ‘drawn’ towards one side. Turn your plants regularly at least a quarter turn every week. (Fuchsias and geraniums need even more frequent turning.
  • Warm compost and dry soil suits Cacti but most plants like humidity. Stand plants on damp gravel or Hortag.

Windowsill Gardening Display Tips

  • Protect painted windowsills as damp from watering can make paint blister. I stand my containers on cork mats. Felt mats look good but hold drips and spills causing more problems than they cure.
  • Windowsills should be decorative and fit in with your internal decor. I use various containers as plant pot holders bought at charity shops to hold and disguise ugly plastic pots.
  • Plants with fleshy leaves like to be watered from below. I stand pots in plastic saucers which I fill with water and let all my plants drink this way.
  • If you grow plants that are a bit tender do not leave them in cold draughts and move them inside heavy curtains on freezing winter nights.

Calceolaria

Favourite Windowsill Plants

  • Pelargoniums like the dry sunny conditions found on many windowsills and can be in flower most of the year.
  • Because windowsills allow you to inspect plants close up I like to grow something a bit different like the Calceolaria above.
  • Windowsill orchids, Streptocarpus or Cape Primrose is one family of plants fit for the purpose. They are available in many colours and some can flower all year round.
  • Herbs are another favourite for a kitchen windowsill, grown for leaves for cooking.

Dahlia Profusion, Propagating and Pointers

Dahlia Profusion, Propagating and Pointers

Pink dahlias

Pretty, perfect, pink Dahlias are alliterative with the title of this post. What is more Dahlias are easy to grow and they produce prodigious posies of pickable flowers (enough with the P’s, Dahlias make a big vase-full not a posy.ed.)

Top Ten Dahlia Pointers

  1. Plant good clean tubers in a large hole that has been well dug and improved with manure or garden compost.
  2. Give each plant plenty of space. Dahlias do not appreciate over crowding.
  3. Support your growing plants with a good stake and string frame work. Dahlias get heavy with all the flowering.
  4. Water regularly and add soluable fertiliser. Dahlias are gross drinkers and feeders.
  5. Pinch out the first early buds to keep the plant growing and not putting early energy into flowering.
  6. To get big individual blooms pinch out any side buds and weak side shoots.
  7. Pick the blooms regularly and new ones will follow. At worst deadhead promptly and regularly.
  8. Plant a range of the many types and varieties – see below.
  9. Flowers will continue until the first frost. Cut back when the leaves are frosted to black.
  10. Save the best tubers for next year in a frost proof shed. In mild zones they can be left in the ground but I prefer replanting in fresh composted soil for the following year.

If in Drought – Try Xeriscaping your Garden

If in Drought – Try Xeriscaping your Garden

Lithrope

If you are doubtful about this summer’s British weather, and how can you be otherwise, then you may need some tips on watering your garden.

Xeriscaping is the creation of a garden that uses less water. No grass to cut, drought tolerant plants and appropriate landscaping are what you need.

Xeriscaping and Other Watering Tips

  • Pull up weeds as soon as they start drinking your water.
  • Plan and plant wind breaks to stop drying winds.
  • Use plants that generally require less water. Grey and silver plants often need less water.
  • Give one good weekly soaking not daily dribbles.
  • Add humus to the soil to retain water and mulch the surface of the soil.
  • Use larger containers rather than hanging baskets, they are easier to water.
  • Use capillary matting in the greenhouse to aid watering
