Euphorbia Euphoria

May 5, 2010 hortoris

Euphorbia Facts

Euphorbia are the largest genus in the plant world with varieties on every continent except Antarctica.
150 species that grow well in UK gardens are listed in the RHS Plant Finder from over 2000 species worldwide.
Euphorbia exist as tiny prostrate annuals, perennials and even Trees.
Some spiny Euphorbia can be confused with Cacti, If you are in Africa it will be a Euphorbia in America it will be a Cactus.
Spines of Euphorbia will be in pairs.
Euphorbia exude a white, sticky, irritating resin when scratched.

Euphorbia Groups

Annuals, Biennials and Short Lived perennialsÂ – grow, flower, seed and die in a season
Annuals, Biennials and Short Lived perennialsÂ – grow, flower, seed and die in a season
Herbaceous Perennials – die back in winter so cut down when unattractive but some varieties have good autumn colour
Biennial-Shooted evergreen perennials – grow leafy shoots that last 2 seasons then flower to be replaced by new shoots. Cut down to ground level when they look untidy
Evergreen or deciduous shrubs – prune only when they grow too big.

Wisteria Hysteria due to Scale Bugs

Spring flowering Wisteria are starting to clothe the walls with festoons of flowers.
It may be an excuse for newspapers to show pictures of Wisteria in full bloom but they are running a story about Asian insects wiping out our Wisterias.

The Problem

RHS entomologists are reputed to be very concerned about Wisteria scale insectsÂ that are 10mm in diameter.

These insects deposit 1000’s of eggs to later feed on the plant’s sap.

Branches and whole plants will succumb over time.

Infections are worse around London and the south.

Stems can become heavily encrusted with scales.

The Future

Experts fear the bug may spread to other trees and fruit bushes.

Treat with a systemic insecticide – it is no time to worry about organic insecticides.

It also gives me a chance to show a white flowering Wisteria

Tips for Moving Shrubs such as Forsythia

May 4, 2010 hortoris

How do you move shrubs that have out grow their current location? When should you move flowering shrubs?

Tips for Moving Shrubs
Move plants only when unavoidable by digging around the plant to create a big root ball of soil.
Heavy rootballs can be dragged into place on a piece of sacking or an opened out compost bag.
Dig a Â£10 hole for a Â£5 plant, loosen the bottom of the hole, mix in some bone meal, back fill, tamp down the soil and water in.
Replant at the same depth – look for the soil level on the trunk or lower branches.
If the shrub is really big and bulky, prune it back hard before moving. You may loose some blossom the following season but it should regrow.

When to Move Plants
Move flowering shrubs in early winter when the shrub is dormant.
Incase of fatality take and root cuttings before moving.
If moving house ask permission of the new owner or stipulate your intentions when selling your property.
If you must move the plant when it is growing, water well for several days before, prune off unnecessary lush growth and do not allow the roots to dry whilst moving.

After Care
Keep your shrub well watered and mulched until it settles down.
Do not stress the plant by striving for excessive blooms in year one
Revitalise the soil around the old hole for your next plant. Humus and nutrients will be needed.

Growing Basil a Sweetherb

May 2, 2010 hortoris

Fragrant and sweet tasting Basil is an easy to grow, popular herb. Aka Sweet Basil, with many other basil types including Sweet Genovese, Thai basil, Lemon basil and Mexican spice basil there is a good range to grow.

Sow From Seed
In May or June fill small pots with moist multi-purpose compost. I use 3″ plastic pots.
Sprinkle seeds thinly on the surface. About 10-12 seeds per pot.
Cover lightly with fine compost or vermiculite.
Keep on a warm windowsill and seedlings will appear in about 2 weeks.

Growing Onward
After 4-6 weeks the seedlings can be planted into individual pots.
Then leave on the windowsill or harden off for outdoor planting
Treat the Basil as an annual.

Outdoor Basil
Plant out in June or July in a sunny sheltered spot.
They make good fragrant container plants.
Feed with a general purpose liquid feed and water little and often.
Pinch out the growing tip to get a bushy plant.

Using Basil
Leave the stems on pick and come again plants taking a few leaves each time.
Grow several plants if you need large quantities for Pesto or other culinary uses.
The seeds can be used to flavour a drink.

Credits
Basil has medicinal and calming properties.

The Power of a Giant Flower Tower

April 27, 2010 hortoris

Public gardens are building more towers of flowers using bedding plants like Busy Lizzy.

Your Own Edifice
On a small scale you can grow mound for pounds by buying mini plugs.
Build a shape using chicken wire or proper units and incorporate containers at varying levels.
Instal a watering or irrigation method as you build.

Plants to Use
Busy Lizzie are a great start as the have a loose habit and will flower in some shade and that will be important if the structure is 360 degrees around
Trailing petunias will aslo do well at covering the structure quickly.
Tyrolean window boxes should also provide the idea of using red trailing geraniums

Thompson Morgan supplied the photograph and have an advisory service for those interested in the ‘Maxi Tower’ large structure.

New Places for Growing Cress

April 19, 2010 hortoris

Egg and Cress sandwiches from your own home grown cress – marvelous and so easy.

I liked the Cress growing in this large wine glass at a local cafe so I thought I would grow some as I did as a child.

Fill your glass with an absorbent paper towel or blotting paper.
Dampen the paper and if necessary add more paper so the Cress will grow above the rim of the glass. This is a bit low to get at the sprouted cress.
Sow seeds evenly onto the damp paper.
To get good germination, make sure the freshly sown seed is kept in the dark.
These will take from ten to fourteen days to mature.
Mustard grows 3 days quicker than cress so if growing both sow Mustard later.
As there is no drainage do not flood with water keep just damp.
Harvest whilst still young and crisp.

Proper cress as in “Mustard and Cress” is Lepidium sativum and the Mustard is Brassica hirta. Beware many supermarkets sell oilseed rape seedlings (Brassica napus) as Cress with little or no flavour.

Beware if you grow on soil the seed husks drag up the soil as the plant grows and can create a gritty feel to your harvest. I like the scent of growing Cress but it may not be to everyones taste.

Other places or receptacles for growing your crop of Cress could include a smart plant pot, broken or chipped china but not grannies best antiques. I put a pot on top of the TV and the water leaked and broke it!

Tips for Growing Cherry Tomatoes

April 18, 2010 hortoris

Chris Winters

Bush tucker trials could refer to Tomatoes grown on bush varieties because they make great ‘tucker’. I love the sweet sharp taste of some of the new Cherry Tomato varieties.

Quick Tips for Growing Cherry Tomatoes

Buy a variety like Sweet Million or Gardeners Delight.
Garden Pearl has been specially bred by Unwins for growing in containers.
Baby Plum Tomatoes are now available in a variety called Sweet Olive.
The Tumblin’ series can be grown in hanging baskets or containers.

Cultivation of Tomatoes

The surface roots take up the fertilizer and nourishment. Encourage them by building soil around the stem.
The tap roots go deep in search of water. Help by making sure you water well into the soil by sinking a pipe or pot near the plant to fill up & make sure the water gets deep down.
Do not be too greedy with each plant. Stop them growing when you have 5-8 trusses of fruit by pinching out the growing tips. This channels the energy into your fruit.
Feed and water on a regular consistent basis.
I still support my Cherry tomato plants with a cane and string.
