What to grow in April 2017

Torrential rain along much of the east coast means a lot of soil is water-logged as April begins. In areas not affected by wet soil, April is a good time to plant out evergreen trees and shrubs where winters are frost-free. See Planting trees, shrubs and vines
Plant spring bulbs in temperate areas and give almond, cherry, nectarine, peach, and pear trees a drink of seaweed extract tea.
If pests bother your broccoli and other brassicas, sow some dill seed between plants. The smell of dill foliage confuses the butterflies and moths that like to lay their eggs on the leaves of the cabbage family. Also check the soil pH around these plants.
The following gardening advice is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be planted in April in Australia and New Zealand. A comprehensive monthly guide that includes planting times for the entire garden, as well as when to fertilise, prune, weed, take cuttings or divide plants, can be found in my book Easy Organic Gardening and Moon Planting (Scribe Publications, 2006, 2009, 2012, also now available as an e-book).

* For gardeners who do not use moon planting: sow or plant out any of the following list at any time this month, although you may find germination is weaker when the Moon is in Last Quarter phase.

Chickpea can be sown in frost-free areas. Leek, spring onions, chamomile and parsley can be sown or planted out, also silver beet (pre-soak seed) in frost-free areas.

Avoid sowing broad beans and peas too early in frost areas. Although the plants are frost-hardy, the flowers are not.
During Full Moon phase, radish and turnip can be sown directly into beds, and early season onion can be sown or planted out. Swede and garlic can be sown in warmer areas, and raspberry and currants can be planted in cold areas.

Time to plant spring bulbs

Just a reminder that April is a good time for planting spring-flowering bulbs in most areas. Gardeners in warmer climates can put bulbs into the vegetable crisper of the fridge for a month’s chilling before planting in May.
Add plenty of compost and some complete organic complete fertiliser to the planting area. Nutrients will be absorbed by the plants during the growing season and withdrawn into the bulbs as the foliage dies back to ensure good flowering the following season, so remember not to remove foliage before it becomes brown. Bulbs are normally planted at a depth twice the width of the bulb. In warm climates, plant suitable bulbs up to twice as deep as indicated on the packet. After planting, mulch the area in early morning when the soil is cooler and keep the planted area just damp until growth appears, then water regularly. For moon planters, Full Moon phase is the best time to plant bulbs. This year (2014) the Full Moon occurs on 15th of April and May.
