Why are Tulips so beautiful yet so hard to grow?

Well, they're not hard to grow any more. Some great new varieties and a few simple rules to follow will have picture perfect Tulips in your garden this Spring.

Tulips are no longer just suited to the coldest areas of Australia, such as Tasmania and the highlands of Southern Australia. Varieties now available known as Single Late Tulips require less winter chilling to produce tall 60cm plus stems and large bold flower heads. Varieties that fit this category are sold in a wide range of colours from white to almost black. I would encourage anybody south of the sub-tropics that likes Tulips to give them a try. Varieties known to perform well include Maureen (white), Dordonge (apricot), Peking (deep pink), Toyota (deep red), Ollioules (light pink), Avignon (orange) and Queen of the Night (burgundy/black). Several others are also available however good stockists will categorise or label them as Single Late or French Tulips, or sometimes Warm Climate Tulips so you won't make a mistake.

Other Fancy Tulips that may also perform well in a normal climate are Burgundy Lace (cerise fringed), Maya (yellow fringed) and Upstar (pink double). So now you know which Tulips to select. This is the first very important step. There are however a few other easy, yet important steps to remember for great looking Tulips.

Purchase your bulbs by the end of March. This allows sufficient time for a cooling treatment in the refrigerator. Chilling your bulbs for 6-8 weeks in the crisper of the refrigerator (not freezer) prior to planting will ensure the longest possible flower stems. Cold areas will not require as many weeks chilling. If you don't get your bulbs till late in Autumn still refrigerate them for a few weeks, always leaving planting until before the third or fourth week in May.

As a general rule never plant out your Tulips before early May. This gives the soil a chance to cool down sufficiently. Whether you are storing your Tulip bulbs in the fridge or just in the shed or cupboard, make sure the area is well ventilated and away from ripening fruit as the ethylene gasses given off can produce flowering disorders. It is a good idea to keep the bulbs in the packaging they were purchased in as this should prevent mould and fungal attack. Be sure not to put them inside any sealed containers.

When choosing a spot to plant Tulips pick a sunny or partly shaded location. Build up the garden beds if necessary to make sure the area doesnt get water logged throughout winter. If the soil is acidic (pH below 6) add some lime and mix it in (this will help most of the plants you grow). Prior to planting is the best time to add some fertiliser to the ground and Tulips love a combination of Blood and Bone with a little complete fertiliser. Tulips prefer to grow in cool soil so plant them about 20cm deep. How far apart is up to personal taste. Personally I think clumps of at least 10 bulbs planted about 12cm apart look stunning in flower. Between 7 and 20cm apart is normal.

Now that they're planted and fertilised very little needs to be done until you see buds appearing. Aphids love eating Tulips flowers so give them a spray with a recommended insecticide. A systemic spray that continues to circulate through the plant system for some weeks after spraying will be more effective than the simple knock-down kind. Your garden centre will advise on what type will be most effective.

Getting great results from newly purchased Tulips is obviously more simple than getting last years bulbs to perform well again but try the following and you may be surprised.

In Spring don't let the ground dry out until the leaves start to yellow. If you have cool to mild summers try leaving your Single Late Tulip bulbs in the ground. Around Melbourne, the south coast and Tasmania it appears to work okay for 2-3 years. What Tulips ideally like over summer is dry ground and soil temperatures of around 20 Celsius. In hot climates, this may be difficult to achieve so the best thing is to try and duplicate these conditions outside the ground.

Dig up your bulbs from mid November to mid December after the leaves have yellowed. Brush off any excess soil and immediately place them in a cool shaded position with good air circulation. As previously mentioned the closer the temperature remains to a constant 20 Celsius the better the Tulip flower will develop. Take care to avoid subjecting your bulbs to lengthy periods of high temperature as this can kill the developing flower and result in leaves but no flowers the next season. While storing your bulbs it can be a good idea to either dust them with some insecticide or place an insect strip nearby to prevent aphids from feeding on them prior to planting.

Once again give your old bulbs the same cold treatment in the crisper section of the refrigerator and plant out in May. Chances are by making the effort you'll have a great Spring Show every year.
