Veggie Garden Tasks

April is the final month for the harvesting the last remaining summer vegetable crops. Vegetables that can be grown almost throughout the year, can also be harvested including broccoli, cabbage, cauliflower, silverbeet and spinach. 

Seedlings of classic winter vegetables, cabbages, cauliflower, broccoli, kale and brussel sprouts can now be planted into well-prepared winter vegetable gardens enriched with Garden Time™ Vegetable Mix. Seeds of peas and broad beans can also be sown. 

Always consider light and drainage if you are developing new vegetable plots. The position of the sun changes in winter, especially where there are tall shelter trees that may shade the winter vegetable garden. Drainage may need to be installed or winter gardens raised to ensure the soil does not become water-logged over the wet winter months. 
 

Herb Garden Care

Often in April herbs require a very hard prune and/or replacement. Where plants have flowered and ‘gone to seed,’ replace them with young, vigorous seedlings. As herbs can be successfully gown in containers, this can be an excellent option for the winter months as you can move them to sunnier locations. Parsley, Mint and Chives are robust varieties and do best over the winter season.
 

Flowering Annuals

April is the perfect month for planting your winter flower garden, this can also include containers on decks and entranceways to add pops of colour. 

As with all soil preparation, add generous amounts of compost as this plays a big part in the successful blooming of winter annuals. Seedlings to plant include alyssum, calendulas, cineraria’s, cornflowers, lobelia, Rusell lupins (South Island), nemesias, pansies, poppies, snapdragon, statice, stock, Sweet William, and viola.

 

Last Chance for Bulb Planting

This is the final month to complete the bulk of your bulb planting. This month's must-plant varieties include beautiful Babiana, Daffodils, Ixia, Iris, Ranunculus, Tulips (can also be planted into May), and Watsonias.
 

Harvesting Fruit Trees 

Late-season apples and pears are now maturing and ready for harvest. The bonus of having fruit trees in the home garden means fruit can be harvested when they taste their very best. 

Ripe feijoas are now ready to be collected from the ground, never pick a feijoa from the tree! 

The first kiwifruit is also ripening. Peach, plum and nectarine trees can be given a copper spray to protect against future bacterial diseases. Pruning can begin next month. 

 

Rose Garden Care

April is usually the last month of free-flowering for many rose varieties. Do not over-fertilise existing plants and remember to mulch with Daltons Premium Mulch & Grow or compost. Continue removing finished flowers and regularly check your roses for any sign of rust, black spot or scale insects.

Use this month to assess the performance of your roses to date. New plants will be arriving next month in the garden centres so it’s a good time to plan any additions. Purchasing plants early means you can choose from healthy specimens.

 

Lawn Care

Time to feed or repair lawns while the weather and soil are still warm. To encourage strong, healthy, dark green grass apply Daltons Premium Lawn Fertiliser to established lawns every 4-5 weeks from late February to late April. To repair smaller patches in your lawn, remove the affected grass and soil around the damaged area and at least 15cm beyond it. Then add Daltons Premium Lawn Patching Gold which has everything you need in one bag e.g. lawn soil, seed and fertiliser, and lightly water. Protect newly sown seeds from birds and maintain regular watering for even germination.

 

Houseplant TLC

With lower light levels as winter approaches, reconsider moving plants to sunnier spots. Reduce watering frequency during cooler months, and when you do water, use lukewarm water to avoid shocking the plants’ roots. 

Apply Daltons Houseplant Tabs and keep misting foliage houseplants with lukewarm water to maintain humidity levels, mimicking their natural environment and keeping them thriving.
