Marrows

Marrows – Introduction

You can expect a high yield marrow crop because marrows are easy to grow. They resemble large courgettes. I actually let some of my courgettes grow big and treat them as marrows.

Sowing Marrows

The best growing conditions for marrow are

  • Warm and sunny location
  • Moisture retentive soil
  • Mineral-rich soil

You must sow the marrow first in pots indoors. However, you can also sow them outdoors at their final location. 

Indoor sowing

  • Sow the plants firstly indoors from mid to late April
  • Ensure that soil temperature is 65–70°F at the time of sowing  
  • Sow the seeds in the depth of 0.5 inches
  • Sow the seeds in a 3 inches pot which is filled with compost

Outdoors sowing

  • Dig in well-rotted manure and home-based compost 
  • Sow 2-3 seeds in the centre of the hole
  • Ensure that you have sown the seeds to a depth of 1 inch.
  • Cover the sowing site with plastic, jar or cloche for at least two weeks after germination.
  • Thin out the weaker seedlings  

Growing

· Harden off the plants raised indoors before planting them outdoors

· Choose a sunny and rich soil for planting the marrows.

· Dig a hole 

· Fill in the manure and compost into the hole

· Spread two handfuls of general-purpose fertilizer in each square. Metre/ yard.  

· Now, plant the marrow in the mid of the hole. 

· Ensure a distance of 3 ft between the plants 

· Water the plants regularly and generously when they start growing

· Avoid splashing the leaves while watering the plants. 

· Feed the plants with high potash fertilizer every 10-14 days. Tomato feed is the best high potash fertilizer. You must spread the fertilizers when the fruit start swelling. 

Harvesting

The harvesting time for marrows starts in mid-summer. You can harvest them when they are 8-12 inches long. You can use the marrow immediately after harvesting. You can also leave them to get matured. Even you can store them for winter use.

  • Harvest the marrows regularly for continuous fruit
  • Harvest the marrows before the frost arrives
  • Ripen the marrows in the sun so that their skin is hard. This step is a must if you want to store the marrows.
  • Store the marrows for several months in a frost-free, dark and cool place.

Common problems

Powdery Mildew

Leaves become stunted and shrink as white powdery deposit forms on the leaf surface.

Remedy

  • Grow the plant in colder conditions
  • Keep the soil moist

Fruit rotting or no fruit 

Neither a pest nor a disease is responsible for this problem. However, it’s a physiological problem. It mainly occurs in the cool early summer, which causes inadequate pollination.

Remedy

This problem will go away in better weather conditions. However, you can also go for self-pollination.

Now the question is how you will hand-pollinate?

  • Firstly, you have to remove the male flower.
  • Secondly, you have to brush the central part. Make sure you’re brushing at the female flower’s centre.

This process is time-consuming. So, let the plant correct this issue on its own.

Grey mould

Grey mould is fuzzy and grey fungal growth. It starts with discoloured patches. It mainly occurs in humid or damp conditions. The damaged parts of the plants are responsible for the entry of spores into plants.

Mould is also dangerous for ripening fruits, such as strawberries. The black spores of the mould stay throughout the winter.  

Remedy

  • Remove the damaged parts of the plant as soon as possible.
  • Clear all the debris infected with the mould
  • Reduce humidity in greenhouses. You can do so by avoiding the overcrowding of seedlings and young plants. Moreover, ventilation of the greenhouses to reduce the moisture is also an excellent option to take the mould away from your plants.
