Tomorrow is the last month of spring
This is the month for planting corn and beans. These cold-averse warm season vegetables have sizable seeds that can be sown direct into the spot where you would like them to grow.
If you are not comfortable sowing seeds, then plants can also be bought in punnets from the garden centre. Beans come in dwarf bush form and as a climber.
Dwarf beans form a self-supporting bushy plant growing approximately 25cm tall and wide. They are quick to reach harvest, ready for eating around seven to eight weeks from sowing.
Planted now they will be ready for Christmas dinner. A highly recommended top producing bean variety is the in the Ican Chefs Best Seed Range called Supreme. It is high yielding, with strong disease resistance and has straight 14cm long beans set high on the plant for easy picking.
The pods are distinctively glossy, very fleshy and have excellent flavour. The bean Supreme comes ready over a two to three week period so a number of sowings every three weeks will give a consecutive harvest through the summer. As a small growing plant they are an ideal vegetable to grow in containers if you are limited for space, as well as in the garden.
Climbing beans form a larger plant and need support. A structure of approximately 1.8-2m high is recommended with trellis, wires or string being ideal for the tendrils to climb around. Climbing beans take about 10-12 weeks to start cropping from sowing but will keep flowering and producing beans for as long as the temperatures remain warm. Some climbing bean varieties will form a tuberous root system that, if left in the soil, will regrow in future years.
To leave your root systems to grow again the next year the vines should be cut off above ground level as the plants die off in the autumn rather than being pulled out roots and all.
A couple of good climbing varieties are; Yates Shiny Fardenlosa which is renowned for long straight, string less, flat glossy dark green pods. It is highly prolific.
Another popular and top performing climbing bean variety is Yates Scarlet Runner, which produces very long pods for a long period through the summer. It's known for continuous picking and heavy cropping. Picking the beans young will give you more tender produce that hasn't had time to get stringy. An added bonus is the attractive flowers before they set pod. Scarlet Runner is also a perennial and will come up again each year.
Corn is an easy to grow and productive crop that grows well in Whanganui. Seeds should be sown now directly into the soil; these will be ready for harvest between mid-February and March. Corn are heavy feeding plants. Before planting I recommend mixing Ican Organic Vegetable Food into the soil and then side dress again regularly as the plants are growing. Corn is best planted in blocks rather than rows as this significantly improves the rate of pollination.
A highly recommended corn variety to grow is tender sweet, like the dwarf bean supreme it is part of the Ican Chefs Best Seed Range.
Its reviews live up well to its description; "extra tender, and full flavour. Very tender husks that do not get stuck in your teeth. Strong germination and vigour, high disease tolerance and early maturing. The best corn variety available."
The Ican Chefs Best Seed Range has been developed by independent garden centres with the aim to put quality and value first. It was addressing the issue that we are in an age where price is often pushed lower at the compromise of quality. This range had garden experts carry out extensive trials as well as advice from vegetable seed specialists in NZ and internationally, to find the very best varieties for NZ home gardeners. The group of independent garden centres have chosen 15 of the very best vegetable varieties for NZ home gardeners.
The varieties have been selected for their superior taste, improved pest and disease resistance, increased vigour and yield. In addition, they are consistent and reliable. As well as bean supreme and corn tender sweet, other seeds from this range that can be sown now include beetroot, buttercup pumpkin, carrot, cucumber, courgette, lettuce, tomato, radish, spinach and tomato.
If you haven't yet planted any potatoes or want a later crop, then it is not too late, potatoes planted now will be ready for harvest in February.
If you have potatoes growing, mound regularly as this increases the length of stem covered on which the potato tubers form. A side dressing of Tui Potato Food around the plants before they are mounded will be beneficial to growth and tuber development.
It is important to now start spraying your potato crop with Yates Mavrik or Yates Success to protect against potato psyllid, which can go undetected for a while but will show up with plants showing a stunting and yellowing of the growing tip. The edges of the curled leaves often have a pink blush. The stem may have swollen nodes and show a browning of the vascular tissue. After a while, infected potatoes develop a scorched appearance and plants collapse prematurely. Potato plants that are infected early end up with small underdeveloped tubers.
The same psyllid affects all plants in the solanaceae family, which includes tomatoes and tamarillo. Using the same mentioned spray treatment as for potatoes is effective.
Protect apple trees from codling moth now
Codling moth caterpillars burrow into apples. They can also affect pears, quince, English walnuts and sometimes plums. Once inside the fruit the insect is relatively safe and will burrow towards the pip cavity and consume the seeds.
The insect "over-winters" as a fully fed caterpillar in a silken cocoon beneath pieces of loose bark on trees or in other sheltered positions. In the late winter or early spring the caterpillars transform to pupae and the first moths generally appear during October-November and can occur into January and February.
The best method for control is an integrated pest management approach. This involves using pheromone traps being hung in a tree. Closely follow the instructions given. Check weekly for population numbers caught in the trap and when larger numbers are recorded, spray with Yates Success to provide a reasonably complete control.
Have a great week.
