  • 00:00: Early Spring Spraying Have a look, you can see a spying ant. To some a friend to others an enemy. What is he doing here? He is looking for these black dots. These are aphid eggs. These eggs spent the winter on this young tree. The ant is waiting for the eggs to hatch.
  • 00:34: When the buds begin to come up, the eggs will hatch into aphid and begin to eat the tree. In this case a Gloster (Malus domestica) apple tree. I have noticed that aphids like to spend their winter on this tree. You can see these eggs everywhere. After they hatch on this tree, they will begin spreading onto other trees.
  • 01:04: How do we prevent it? We can physically remove it by hand. But there is no guarantee that this will help. And it is not time effective for a big garden. Therefore we will perform an early spring spraying.
  • 01:35: What do we use for such spraying? And when do we spray the trees in spring? And when do we spray the trees in spring? You begin to spray just after the snow is gone. However, do it before the trees are in full bud. Before vegetation. The snow is gone, there is no wind, so we can begin the first round of spraying. What do we spray with?
  • 02:05: You can use a reliable "Bordeaux" mixture. Also called the "Bordo mix". You can use a reliable "Bordeaux" mixture. Also called the "Bordo mix". That is calcium hydroxide (slaked lime) mixed with copper(II) sulfate (blue vitriol). You can buy this mixture anywhere. However, I prefer using urea. You can also buy this set in most gardening shops. This set is specifically for early spring spraying.
  • 02:36: This is urea mixed with copper(II) sulfate (blue vitriol). This is a set for 10 liters of water mixed with 700 grams of urea and 50 grams of copper(II) sulfate (blue vitriol). Why do I prefer urea to "Bordeaux" mix? This is simply because urea also serves as a fertilizer.
  • 03:10: After spraying it gets into the trunk of the tree and the buds. In early spring the tree gets a very good dose of urea as a nitrogen fertilizer. Another benefit of this mixture is it suppresses vegetation. The sprayed buds will begin to burst a week later than others. As a consequence, the sprayed trees will bloom a week later as well.
  • 03:48: Why is that good? In this way we can prevent early flowers of peach, apricot and prunes from freezing. Also, this allows to get rid of scabs (venturia inaequalis) from last year and harmful insect eggs. Apple blossom weevil (Anthonomus pomorum) do not like this kind of spraying. If you spray it directly on them, these insects will vanish immediately. Make sure you spray the tree thoroughly so the tree is damp.
  • 04:27: You must also spray the leaves from last year around the tree carefully. This will stimulate decomposition of the old leaves. It will destroy any unnecessary fungal matter and any harful insects. It will destroy any unnecessary fungal matter and any harmful insects. By the way, urea in this kind of concentrate, 700g of urea and 50g of copper(II) sulfate (blue vitriol) mixed with 10l of water, can be used not only for spring spraying, but also for autumn spraying.
  • 04:57: Bear in mind, timing is very important for autumnal spraying. Autumnal spraying with urea, must be done after the apple trees drop around 20-30%, even 40% of leaves. Never sooner than that. If you spray your trees in the end of August beginning of September, before the leaves begin to fall We could provoke a late growth of the tree. This would result in a widespread freezing in winter. Therefore, in autumn
  • 05:28: you must only spray the entire tree and the area around the tree after the required foliage has dropped. This stimulates decaying of the old leaves, kills fungal spores and of course fertilizes the soil. Let's get started. It is very easy to prepare the mixture for spraying.
  • 05:58: Take a clean bucket, pour 700g of urea into 10l of water and stir until it dissolves completely.
  • 06:28: Next, add 50g of copper(II) sulfate (blue vitriol). Next, add 50g of copper(II) sulfate (blue vitriol).
  • 06:58: There you have it. Pour this mixture into your sprayer and you are free to begin your work.
  • 07:29: When dealing with all toxic chemicals, you must wear a mask. You must. I would also recommend wearing glasses when dealing with pesticides. Try working in calm weather with no wind, so your spraying would be effective and safe. Health and safety is essential. A few last words about urea.
  • 07:59: You can fertilize your trees in summer, but you must use ten times less of the concentrate. In other words, you should use 50g of urea with 10 l of water. you should use 50g of urea with 10 l of water. This will provide more nitrogen to your trees. This is only necessary when there is in lack of nitrogen, usually in drought. In this case, you provide nitrogen through the sprayed leaves.
  • 08:29:
  • 08:59: This is a very simple, but necessary procedure for your garden. You ought to repeat this process with your shrubbery. Although, gooseberries and black currant shrubs bud earlier, so you should spray them a little earlier. Good luck!
