In The Garden This Week

It's spring and that means tomato planting time. We're again talking tomatoes and their garden companions this week and loads of other jobs to do.

We're planting tomatoes, dividing Cymbidiums, and spreading the mulch to make the most of watering. We'll take the time to admire wisteria and check out what's on in the gardening world around us.

 


Divide Cymbidiums now

 

Questions of the week

Q: When do I divide my Cymbidium orchid?

Perfect timing - right now!

Divide Cymbidium orchids after they have finished flowering. Remove spent flower spikes from the base. Using a sharp knife (or pitchfork if necessary) gently divide orchid into divisions of 3 to 5 pseudobulbs. Replant into an open, coarse orchid compost, water in well with a weak seaweed solution and place into a shady position. After four weeks, start a fortnightly drench with a soluble fertiliser such as Strikeback for Orchids. Bring your Cymbidium out into the morning sun from February onward to encourage new blooms for the following flower season.

 

Q:How do I treat borer?

Unfortunately, there are no chemicals available for home gardens that control borers. Mechanical treatment is best. Remove frass and sawdust to expose borer hole. Then poke fuse wire or similar into the hole. Once satisfied control has been achieved block up hole with candle wax. Fertilise tree, water in with seaweed solution and water well and mulch.

When borer strikes it can be a sign your trees are under stress needing some TLC, they are susceptible to attack, bird populations are low or from just bad luck. Whatever the reason urgent action is required. In large trees it is always advisable to obtain expert arboricultural advice and don't delay.

With smaller trees like native shrubs, citrus, fruit trees, ornamentals like crepe myrtles or camellias, urgent action is also advised.

Q:What's wrong with my tomato?

This week was full of tomato questions, and we expect more in the weeks to come. Tomatoes are very easy to grow and reward a little gardening effort in spades with baskets of fruit through the summer. But there are a few pitfalls to avoid that can lead to some of the most common tomato problems, like wilt virus, end rot, fruit fly damage and grubs.

So we put together a helpful article identifying and discussing the most common tomato problems and their solutions. Check out the full article, 'How To: Fix your tomatoes'.

We're giving away a 25cm Tomato seedling with every Garden Clinic Platinum Membership this week, plus a swag of goodies to keep it happily growing strong. Get yours when you join or extend your membership today.

It's Tomato Time!

 

It's time to....

We are excited about the unfurling new growth and stunning spring floral displays. Here are a swag of jobs, tips, tricks and things to look out for in the garden this September.

Temperate gardens - It's time to boost spring growth above and below the ground by nourishing garden soil with a layer of compost 35 mm thick and a dose of organically based fertiliser. Click here for more spring jobs in the temperate garden

In the subtropics - Clear and prepare vegetable beds for summer crops. Check soil pH and if below 6.5, topdress with garden lime at the rate of one handful per square metre. Water in. Two weeks later, topdress beds with a quality organic garden fertiliser containing ground rock minerals and humates (humic acid), and compost or composted stable manure and dig into beds with a fork.

Flowering now

Rose Mallows Hibiscus

Want big blousy flowers? It’s hard to go past the new rose mallows, Hibiscus moscheutous, which offer truly plate-sized blooms on a fast-growing, bushy perennial that grows to about 1m. This one is ‘Cherry Cheescake’, which makes a dramatic show in late summer and autumn featuring ruffled white petals tipped with magenta and a cherry-red centre. It’s new to the Hibiscus ‘Summerific’ collection from Proven Winners, all of which love moisture (the other common name for these plants is swamp mallow, so there’s a hint!) and respond to generous feeding.

Leptospermum laevigatum, Coastal Tea Tree

A very hardy coastal, frontal dune small tree, 4-5m tall X 3m wide with white bee attracting flowers in spring. Grows in a wide soil pH range from acid to alkaline with a sandy to clay loam profile so long as it’s well drained. Soft grey leaves similar colour to olive trees and also grows well in a large tub.

Suited a wide climatic range from sub-tropical, cool and warm temperate to Mediterranean, and semi-arid zones. It forms a compact open headed small tree in light shade or full sun and withstands windy, exposed gardens. Also tolerates light frost

Can be trimmed into a hedge, or even topiary. Bonsai specimens have been seen. Used in erosion control, street trees and as a quick growing wind break. Several dwarf varieties around including:-

L. l. ‘Fore Shore’, excellent as a replacement for Box hedging, grows tight, compact to 40cm x 1m

L. l. Shore Tuff’, 50cms x 1.5m wide

On the road

Gardens destroyed by Hurricanes

Gardens are often severely hit by hurricanes in the Gulf of Mexico and the southeastern states of the USA. But the the 2017 Hurricane season has been particularly severe, with hurricane Harvey bringing disasterous flooding to Texas, and Hurricane Irma - one of the most severe tropical storm ever recorded.

In Florida gardens like the historic Cummer Gardens remain closed to the public after sustaining significant damage and having been submersed in salt water for over 24 hours during the storm.

The good news for our Mexico & Cuba travellers leaving later in October is that while Hurricane Irma made landfall on the north east coast of Cuba, Havana was not badly affected.

 

Off to Europe

Next week we say farewell to our Italy tour group, hosted by Sandra Ross. These lucky travellers are in for a real treat! They'll be visiting the classic renaissance era gardens that Italy is famous for, enjoying the history, art, stunning scenery and fabulous food!
