Soils and Fertilizers

By -
The importance of using the correct soils and fertilizers are of big importance to our company. We are striving towards a greener future and using all bio-degradable products is a good start. 
 As previously stated we will be propagating:
  •  Avocados using the grafting and air-layering technique (with root stock from seedling)
  • Arum lilies using micro propagation
  • Tomatoes using seeds and a hydroponic system
All three of these different techniques use different mediums and fertilizers for different phases of the growth of the plant or seedlings.

·         Avocados:

  • For the Cuttings 
·       Medium :

1:1 - peat moss: perlite (good balance of moisture and drainage)
              
·       Fertilizer an Rooting Hormones:

IBA (indool botter suur) – Rooting hormone
Organic fertilizer – Fertilize only after five week transplant(1st transplant),

·       Environmental Conditions:

Indirect sunlight

·         Relative Humidity:

Increase humidity in greenhouse
± 70%

·         Extra equipment

Pot’s for cuttings

  • After about two weaks, check the progress of the cutting by tugging it gently. If you feel a slight resistance, you have a root system. After another 3 weeks, transplant cuttings into a bigger pot or in the ground.

Vegetative growth

· Environmental Conditions:

Trees should be planted from September to November when soil temps have warmed and in an area protected from wind and frost.

· Medium           
  
Avocados are shallow rooted trees with most of their feeder roots at the top ±20 centimeters of soil. Because of this, they need to be planted in well aerated soil.

·  Fertilizer and Fungicide

That is high in Nitrogen (Nitrogen promotes shoot growth in an avocado tree). Calcium ( roots, good structure). Potassium for growth and fruit bearing. Phosphorous for a healthy metabolism. Calcium (roots, good structure). Magnesium ( photosynthesis). Iron and Manganese ( health)The roots of some types of plants, such as schefflera (Brassaia actinophylla), are almost always infected with Pythium spp. despite preventative use of fungicides. Fungicides remain an important method to control losses due to Phytophthora and Pythium spp.


Flowering Stage      
· Fertilizer
To improve the quality of fruit provide Zinc and Calcium during the first 6 – 8 weeks of fruit growth.

First year:
Outdoor trees – Fertilize every month


Indoor trees –Fertilize every 3 weeks


Important Minerals:

Avocados need the right amounts of Nitrogen and Phosphorous for healthy metabolism, Potassium and Zinc in the fruit, Calcium for good structure, Magnesium for good photosynthesis capacity, and Boron, Iron, and Manganese for good health
What minerals do avocado trees use? The first four listed below are the most important minerals for avocado trees.

Introduction to Tomato proagation

TOMATO PROPAGATION At GrowNurs we propagate our tomato seedlings via Hydroponics.Hydroponics is the process of growing a plant in a liquid with added nutrients but without the presence of soil. Tomatoes grown via hydroponics We use Hydroponics because there  are many advantages using this technique,the biggest of which is a greatly increased rate of growth within our plants.Our plant mature faster and produce up to 30 percent more than the same plant grown in soil. The reason for this is because the plants will not have to work hard to obtain nutrients since there is a continual supply of nutrients available via the solution being pumped through the system.This allows the plant to focus more on growing upstairs instead of expanding the root system downstairs. A hydroponic system uses less water than soil based plants because the system is enclosed,which results in less evaporation.Hydroponics is better for the environment because it reduces waste and pollution from soil...

Arum Lillie's Using Fertilizer and Preparation of Soil

Fertilizer: Although inorganic fertilizers are more readily available we believe in using organic fertilizers. Inorganic fertilizers has the ability to burn the roots, the basal plate as well as the leaves if it comes in direct contact with it, which is another reason why we prefer organic products as it does not have these dramatic negative effects when the concentration of the fertilizer is slightly off. Fertilizers come in granular or liquid form. Granular fertilizers are better because the don't dissolve as quickly, they remain in the soil longer, and the longer the better. Nitrogen (N) is important for preparing soils for bulbs to be able to start their leaf growth. Phosphorus(P) and Potash are good for overall health, resisting disease, root growth and flowering. When adding granular fertilizers, mix with soil ate the bottom of the planting holes. Adding a very diluted liquid fertilizer to the misting system, that regulates the relative humidity in the greenhouse, ...
